Mandatory speed limiters are systems built into cars to stop you from driving too fast. However, they’re not as restrictive as you’d think. 

Speed limiters are becoming a legal requirement across the UK as lawmakers aim to make roads safer and reduce road accidents. 

On this page, we’ll explain how they work, which cars are affected, and what British drivers need to know for 2025 and beyond.

Mandatory speed limiters are systems that use smart speed-limiting tech (also known as Intelligent Speed Assistant ISA) to monitor and restrict your driving speed.

ISA uses GPS and camera-based traffic sign recognition to understand the speed limit in any given area. 

If the driver goes over the speed limit, the mandatory speed limiter reduces the engine's power and slows the car. The driver will also receive a visual or audio warning if they exceed the speed limit. 

For example, if the car determines that the speed limit is 30mph and you try to do 40mph, your car will push back slightly on the pedal to warn you and reduce speed.

Sometimes, you need to break the speed limit if a situation puts you or others in danger. 

 be overridden so, if you need to accelerate quickly to avoid a dangerous situation, you still can, but the system will kick back in soon after.

The main reason mandatory speed limiters have hit UK and EU roads is safety. 

Speeding is one of the biggest contributors to unsafe roads. The European Commission has stated that speeding is a key factor in

The idea is that if everyone sticks to the limits with the help of speed limiters, roads become safer for drivers, passengers, pedestrians, and cyclists alike.

These systems are part of a wider push towards smarter, safer driving tech. Just like automatic emergency braking and lane-keeping systems.

What are the legal requirements for speed limiters?

Speed limiters have been a legal requirement for cars manufactured in Europe since 6 July 2022, and from 7 July 2024, all car manufacturers will be legally required to guarantee that all cars in their showrooms have speed limiters fitted. 

The limiters aren't just an EU scheme, though.

The July 2022 ruling was also put into UK law. So, it applies to all UK cars, even though they're not part of the EU. If you’re buying a new car from July 2024 onwards, it will come with a mandatory speed limiter. 

Cars affected by the UK speed limiter rules

All new cars sold from July 2024 must comply with mandatory speed limiter rules, including every major brand and model introduced since then.

Every new car sold, whether a fresh design or a long-standing favourite, must be equipped with a speed limiter. So even familiar models like the Ford Fiesta or VW Golf will include the technology.

Used cars that were registered before this rule came into effect won’t need to have the system retrofitted. So, if you’re driving a car that’s a few years old, you don’t need to worry (yet).

Yes. Some specialist vehicles, such as emergency services cars and vans, may be exempt.

Older cars registered before the rule changes also aren’t affected or required to have speed limiters retrofitted. This may change in the future, but for now, you won’t have to worry about this in your car repairs. 

However, if you need to manage the cost of any future repairs

options can help you spread the cost of essential services.

Upcoming mandatory speed limiter regulations

The July 2024 ruling was the last big mandatory speed limiter ruling. 

Since then, no further updates to the law have been put in place, and there aren’t any further changes to be aware of. 

Some want to expand ISA systems and make them stricter to enforce speed limits more thoroughly. But for now, the focus is putting these systems into all new cars.

If your car was made after July 2024, it very likely has a speed limiter. 

You can check the steering wheel or indicator stalk if you’re unsure. Look for a button with the letters “LIM.” You can also check for a cruise control symbol. This is signified by an arrow on the speedometer. 

Do speed limiters mean you won’t get speeding fines?

No. You can still get caught for speeding if you have a mandatory speed limiter, as you can override the system by accelerating harder. Ultimately, you’re still responsible for driving the speed limit.

Mandatory speed limits at first sound like a dramatic change, but really, they’re a soft push towards safer driving without taking away your control.

If you’re purchasing a new car, make sure you ask about the ISA system and how it works to ensure you understand how the limiter will affect your drive.

The Ford Kuga. It’s practical, good-looking, and comes with all kinds of features. But like any car, it’s not without its problems. If you’re driving one (or thinking about it), knowing the Ford Kuga’s common quirks can save you a whole lot of stress and money down the line. So, let’s get straight into it: what should you keep an eye out for when it comes to the Ford Kuga?

Ford Kugas often suffer from engine issues, especially diesel models, ranging from rough idling to full-blown engine damage. There have also been reports of software bugs causing misfires or delays in response, especially after updates. 

And while the car's diagnostic check can help spot things early, these engine gremlins are often frustratingly vague until they become expensive. Worst case? You’re looking at an 

What is the clutch problem on the Ford Kuga?

Premature clutch wear is a known problem in manual Kugas, particularly older diesel models. You might notice a strong smell, difficulty changing gears, or a clutch that just doesn’t feel quite right. The issue often comes down to a failing clutch pressure plate or a worn clutch pedal. Some drivers even have to replace their clutch more than once. 

If you're staring down a big bill, Bumper's 

 lets you break it into easy monthly payments. It’s a smarter alternative to high-interest loans – and way less painful than paying it all upfront.

Blocked DPFs (diesel particulate filters) are a well-known issue in Fords, including diesel Kugas. And this is especially true if you mainly drive short distances. It’s especially common for city drivers, where the car doesn’t get hot enough to clear the filter properly. Symptoms? A strong smell, reduced power, or a warning light on your dashboard. If you ignore it for too long, it could cause serious problems under the bonnet. 

What is the battery problem with the Ford Kuga?

Battery drain, flashing warning lights, and dodgy wiring are common electrical problems in the Ford Kuga. Most of these problems stem from ageing battery components or dodgy wiring. If your Kuga won’t start or keeps dying after short trips, it’s worth checking the main and backup systems. Get it checked as soon as possible. Those

Brake pads on the Kuga tend to wear out faster than expected, typically if you're driving in stop-start traffic or carrying heavy loads. But it’s not just 

 you need to watch out for with the Kuga. Over time, discs can warp, callipers can stick, and fluid can leak. This affects performance and bigger repair bills if left unchecked. 

What is the coolant problem with the Ford Kuga?

Some diesel Kugas have suffered from fuel injector issues, leading to rough performance and unexpected fuel leaks. There’s also a risk of coolant leaks. If ignored, these can lead to overheating and a damaged engine. It’s not always easy to spot these early, so watch out for strange smells, puddles under the car, or sudden drops in fuel efficiency.

What is the gearbox problem with the Ford Kuga?

Sticky shifts, slipping clutches, and rough gear changes are some of the most common gearbox complaints on the Ford Kuga – whether you’re driving manual or automatic. Some drivers report hesitation or lag after software updates, while others struggle with gears grinding or refusing to engage smoothly. It’s not always a quick fix either. While some issues can be sorted with a software tweak, others may point to clutch wear or deeper gearbox trouble.

Ford Kuga problems: Should they put you off buying one?

The Ford Kuga’s problems shouldn’t put you off if you’re in the market. It’s one of the UK’s best-selling SUVs – and for good reason! But, like any vehicle, it has its problem areas. Knowing what they are means you can spot the signs early, stay safe, and avoid nasty repair costs. With Bumper’s easy

Ford-Kuga-Probleme: Worauf Sie achten sollten

The Ford Puma is a relaunch of an old model, but instead of a sporty 2-door coupe, the new one is a crossover-style SUV, to cater to a modern market. The Puma borrows many of its underpinnings from the outgoing Fiesta, but is it as reliable as the Fiestas of old?

In this guide, we take a look at any common problems with the Puma, and its overall reliability. We’ll cover:

Overall, the Puma scores quite well on reliability charts, with a score of 90% on WhatCar?’s survey; that said, it placed near the bottom in their small–SUV ratings, placing 17 out of 22.

Thankfully, most issues were resolved pretty quickly, but reports ranged across most aspects of the car, from engine issues to electrical and build quality. 

A manufacturer recall is when a defect with the design or manufacturing of the car is detected, forcing them to offer a free remedial service via main dealer garages. The Ford Puma has had a number of recalls since its introduction in 2019.

To check if your car has been recalled, enter your VIN number on the 

Part of the assembly that holds the driver's airbag to the steering wheel was found to be faulty. The remedy is pretty simple but vital: a new spring is fitted to the assembly at a Ford dealership.

Around 24,000 vehicles were affected by this issue, so be sure to check if your car is one of them.

eCall is Ford's automatic emergency services telephone system, which sends your location to the emergency services in the event of a serious accident. A software update at the main dealer is all that's needed to resolve this issue. Thankfully, only around 100 cars were affected.

An oil separator is part of the engine's PCV system, something that helps to reduce harmful emissions from the engine by recirculating them through the engine. An issue was detected across many Ford vehicles, including the Puma, Fiesta and more. 

The issue came about from a damaged batch of Oil Separators that were fitted to around 9,800 Pumas. The fix involves checking for damage and replacing if necessary.

On some Hybrid Pumas, it was noticed that the battery terminals on the hybrid battery system were not tightened to the correct torque level, potentially giving rise to them loosening over time. 

This one was a very easy fix for the Ford mechanics, and only affected around 430 cars, so whilst it isn’t a huge concern, you should still be sure to check if your car has had the recall work done.

Almost every Puma available in the UK is fitted with an EcoBoost petrol engine, which is most likely due to its high fuel economy and respectable power figures. However, the Ford EcoBoosts used to be somewhat infamous for their reliability issues.

The main problem in the UK with EcoBoost engines is caused by the wet cambelt design, however, the Puma uses the redesigned EcoBoost engine with a timing chain instead. Although the oil pump is still driven by a wet belt. 

You can read more about the issues with the wet belt here. In short, the belt can cause issues with the oil supply to the engine, so make sure you select a car that has a full service history.

Some owners have reported overheating issues with their Puma, something that can lead to serious engine damage if left untreated. Most owners find the issue presents at higher RPMs. Symptoms include a high temperature on the gauge and a lack of hot air from the car's heater. 

The cause of the fault lies with an electric valve between the coolant hoses and the heater matrix. This causes a restriction in the flow of coolant around the engine.

The Puma offers a good compromise between style, compactness for city driving and an elevated SUV driving position. If these features are important, and you can secure a car with a great service history, the Puma is definitely worth considering.

First introduced in the early 90s, the Sportage still makes up a large proportion of Kia’s sales, proving the SUV body style coupled with a wide range of engine and trim options is a crowd pleaser in the UK market. 

Kia offers a great warranty as standard on their cars, but does that mean you should consider buying one for a reliable, dependable family car? In this guide, we’ll find out:

Petrol-engined Sportages are generally considered to be reliable, scoring over 90% on WhatCar?'s surveys, with most problems being minor and fixed promptly. The Diesel engined Sportage, on the other hand, has quite a poor record. 

Over half the diesel cars surveyed had an issue, most of these being engine-related, and taking over a week to resolve. This gave the Diesel Sportage a reliability rating of just 66%.

Recalls happen when a manufacturing or design fault is detected after the cars have been sold, requiring the affected vehicles to be brought back to the dealership garages to have the issue resolved. Recalls are paid for by the manufacturer. 

The Sportage model made from 2019 onwards has a few recalls, some affecting a large number of vehicles. Check for outstanding 

Nearly 7,000 cars, made between August 2022 and March 2023, are affected by a software glitch that affects the start-up of the instrument cluster in certain situations. This can mean the driver is not shown the digital dash correctly. 

The fix is simple, a software update applied by the Kia main dealer.

An issue with the tandem oil pump inside the engine can affect the lubrication of the vacuum pump and cause premature failure. In turn, this can cause a loss of vacuum pressure, reducing the effect of the power-assisted brakes. Ultimately, this fault can reduce braking effort.

With quite a large number of cars affected (around 21,000), it’s vital to check your car, or any prospective cars for this issue. The remedy is fairly involved, requiring the oil pump to be checked and repaired if found to be faulty.

Another vacuum pump-related problem, this time the fault is with the ECU’s software, causing increased RPM and therefore load on the vacuum pump at start-up. This again can cause the vacuum pump to fail, resulting in reduced braking assistance. 

Thankfully, this fault is good bit easier to resolve, requiring just a software tweak. This fault only affected around 3,000 cars, so it’s less likely to affect yours, but it’s still worth checking.

The most common engine faults to occur with the Sportage involve the diesel engine variant, rather than the petrol. Faults range from blocked DPFs, faulty EGR valves and rough running. 

A DPF or Diesel Particulate Filter is a device that filters out a lot of the emissions produced by a diesel engine. It does this by trapping the soot and performing a high-temperature flushing cycle called a regeneration. Faults have been noted by a number of owners that, despite using the car for longer journeys, the DPF became clogged. Check out the average 

An EGR valve is another emissions-limiting device that recirculates an amount of exhaust gases back into the engine. If it fails or becomes clogged, as some drivers have reported with the Sportage, it can cause poor running and a rough engine idle. Typically, resolution involves removing and cleaning the EGR valve, which can be costly depending on the severity. 

Offering a good compromise between efficiency and interior space, it’s clear to see why the Sportage is one of Britain's best-selling cars. That said, with the number of owners having issues with the diesel engine variants, I would definitely recommend the petrol or hybrid options.

The Toyota Yaris Cross, introduced in 2021, is a crossover version of the extremely popular Yaris. It features a similar compact layout, making it great for city driving, with the higher driving position of a crossover. 

But should you consider a Yaris Cross for your next car, are they reliable, and do they have any known problems? In this article, we explain all.

Yes. Toyota regularly ranks in the top three manufacturers for reliability, and did so in 2023, only being beaten by their sister company, Lexus. The Yaris seems to follow this trend too, placing 5th out of 22 cars in WhatCar?’s small car reliability test.

Further to that, Toyota offers a good 3-year warranty from new, which is extended for a year every time you get a service done at a Toyota dealership - that’s a pretty good deal and should give peace of mind.

A number of owners have reported issues with the Yaris Cross’ 12V battery system not being able to start the engine when leaving the car for more than a few days, or doing many short trips. The cause is thought to be the hybrid system not charging the battery sufficiently.

Some owners, via their Toyota warranty, have had the problem fixed with a larger capacity battery. This is a pretty simple fix, but it is a problem that most cars never have an issue with! The consensus is that the original battery is too small capacity.

If you are experiencing this issue, be sure to contact Toyota before fitting a larger battery yourself though, as a non standard battery could void the warranty.

One of the many concerns from would-be hybrid owners is the longevity of the hybrid system, especially the battery. It’s a justified concern, as it’s vital to the function of the car, and can be expensive to replace. 

Unfortunately, as the Yaris Cross only came out a few years ago, we don’t have much information on this. There are very few reports of hybrid batteries needing to be replaced. 

For peace of mind, Toyota typically offers a 10-year battery warranty on the high-voltage battery used to power the hybrid system, but be sure to check this is the case with your car. 

The Yaris Cross, like many modern petrol cars, comes fitted with a Petrol Particulate Filter (PPF or GPF). Much like a Diesel Particulate Filter, this reduces the amount of particulates that are emitted from the car's exhaust.

Some owners have reported issues with the PPF becoming clogged, despite using the car, and this causing the car to have limited power whilst driving. This can be a scary experience if it happens whilst on the motorway.

Like issues with DPFS, this clogging is mainly caused by limited usage, short journeys or infrequent use. This means a car with very low mileage might not be as reliable as one that’s done nearer the UK average per year.

Whilst this is not really a reliability issue, it is something that many owners pick fault with on the Yaris Cross: cabin noise at high speeds. This is probably a symptom of the car's lack of sound insulation - to keep weight and fuel consumption down - and its raised ride height. 

In some cases, owners have resorted to cruising at lower speeds when on the motorway, or swapping the car for something else altogether.

Again, whilst this isn’t going to leave you stranded, it’s something to consider if you do lots of high-speed motorway driving. 

From our research, the Yaris Cross seems to have very few recurring issues. I’d be happy to recommend this car to anyone, provided the storage space, styling and wind noise are not a limiting factor! 

Considering also the impressive Toyota warranty, I would say a Toyota of any kind is one of the best buys on today's new, nearly new or used market.

The Ford EcoBoost engine was first launched in early 2012 as a 3-cylinder turbocharged petrol engine, with a power output comparable to that of a much larger engine, whilst still keeping emissions low. 

Since then, the EcoBoost has been available in almost all of Ford UK’s range of cars, but it has not come without its issues, to the point where you’ll get many people suggesting not to buy any EcoBoost-engined cars at all. 

So what's the truth behind the Ford EcoBoost engine reliability, and should you avoid them?

What is the Problem With EcoBoost Engines?

The wet belt: Engines require a system to keep the rotation of the crankshaft in time with the rotation of the camshaft(s), in most modern cars, this is done with either a cam belt or cam chain. Learn more about the 

The EcoBoost engine used what’s known as a “wet belt”, this is a rubber cam belt that runs in a bath of oil to reduce noise and friction within the engine. The issue comes in that engine oil, particularly that contaminated with fuel, degrades the rubber of the belt over time. 

This degradation led to remnants of the belt becoming clogged in the oil pickup at the bottom of the engine. This leads to improper lubrication, premature wear and/or catastrophic engine failure.

It’s important to bear in mind that despite some owners having issues, if well maintained, the vast majority of Ecoboost engines offer reliable and efficient service to their owners. That said, some engines in the lineup don’t have the aforementioned “wet belt” issue.

Certain 1.5-litre engines, and certainly those made after 2019, do not suffer from the wet cam belt issue, but some do still use a wet belt to drive the oil pump, so these can experience similar issues.

With the likelihood of having a cam belt issue depending on the year of manufacture, engine model and service history, it’s best to double-check the car you are looking at sufficiently before committing.

Since the EcoBoost was released, most of Ford's cars have the engine, including:

How to Avoid EcoBoost Issues With Your Ford

If you already own a Ford with an EcoBoost engine, don’t panic, there are a few things you can do to avoid the dreaded engine failure issue, starting with:

How Much Does Repairing an EcoBoost Engine Cost?

If your EcoBoost has suffered significant damage associated with the wet belt clogging the oil pickup, it is likely you will need a new engine. On average, owners pay around £5,600 for a new engine to be fitted. 

In some cases, the engine is not a complete write-off and can be repaired at a lower cost; this will depend on how long the engine has been running with low oil pressure. 

In some cases, as a “gesture of goodwill”, Ford have assisted with the cost of replacing the engine. This is rare, however, and will often require a comprehensive history of the car, and even an independent report proving the belt is the cause of the problem, rather than servicing.

What to Do if Your EcoBoost Engine Fails?

If you have a Ford with an EcoBoost engine that has broken due to a wet belt issue, and the car is outside of warranty, you really only have two choices: either replace the damaged engine or sell the car as-is. 

With replacement engines costing over £5,000, it is a careful balance to decide if the car is worth it, compare prices of cars on the used market, with similar spec, mileage and year. 

If your EcoBoost Ford has an issue, related to the timing belt or not, Bumper’s zero-per-cent interest financing can help you get your car back on the road

A diesel scrappage scheme offers cash incentives to trade old, polluting cars for cleaner models. 

Scrappage schemes first launched in 2009 to cut emissions, boost air quality, and encourage the switch to greener vehicles. The goal? A cleaner environment and more sustainable transport for 

Right now, there’s no UK-wide scrappage scheme in place. But there are some great alternatives out there, we’ll explain these and how they work below. 

There isn’t currently a UK diesel scrappage scheme. But there are a few manufacturer-led projects that aim to take older 

 scrappage scheme in London aimed to cut air pollution by removing older, high-emission vehicles that didn’t meet Euro 6 diesel or Euro 4 petrol standards. 

It offered financial incentives for switching to cleaner cars, including up to £1,000 for motorcycles, £2,000 for cars, and £10,000 for wheelchair-accessible vehicles. 

The scheme closed on 8 September 2024 after receiving over 54,000 applications. You cannot apply now, but 

existing submissions will still be processed.

 vehicles must still pay the £12.50 charge when driving in the zone in 2025.

offering discounts of up to £6,000 when you trade in an older diesel vehicle. This incentive applies when buying a new, more environmentally friendly model from their range.

The scheme encourages drivers to replace high-emission cars with newer alternatives, helping reduce pollution and supporting the shift towards more sustainable driving, whether that’s a fuel-efficient petrol, hybrid, or electric Volkswagen Group vehicle.

 aims to remove high-polluting vehicles from the road and gives you three great options if you’re eligible. You can get:

You need a non-compliant vehicle and live or work in the CAZ to qualify. You must’ve owned the car since before the 1st of June 2021 and meet certain income or job criteria.

The good news is that there's no fixed end date—the scheme runs until the £4m Government funding runs out.

When searching for diesel scrapped schemes, you might notice one trend—lots of options and brand-led initiatives pop up, but none seem to be in action. 

To help you separate the past from the present, we’ve rounded up the inactive UK scrappage schemes below:

Other manufacturers that used to offer scrappage/trade-in deals include BMW, Fiat, Ford, Mazda, Mercedes, Mitsubishi, Skoda, and Vauxhall. 

Hopefully, we’ll see some new schemes appearing in the next few years.

What cars qualify for a scrappage scheme?

Your car must meet certain age and emissions standards to qualify for a UK scrappage scheme. 

, UK scrappage schemes typically accept cars registered after 2015 that do not meet current emissions standards. If petrol cars are accepted, they must be registered after 2005.

The vehicle must also be in the owner’s name for at least six months. Some schemes may have additional criteria, such as income or location restrictions. 

If a manufacturer runs the scheme, you’ll have to have one of their vehicles participate. They usually don’t allow competitor makes.

Always check specific scheme rules for complete eligibility details, as they are never exactly the same.

Scrappage schemes let you trade in your old car for cash or discounts on a new, eco-friendly vehicle. 

Simply, you trade in your old car, and in return, you get a financial incentive to upgrade to a cleaner model, reducing pollution and saving you money in the process.

You’ll also need your car registration details and certain documents to prove ownership. Gather these beforehand to save time.

However, you must meet strict eligibility criteria, as detailed above.

Do you get money for scrapping a car in the UK?

​Yes, you can receive money for scrapping your diesel car through various scrappage schemes. 

Government-backed programs may offer grants up to £4,000 (Birmingham CAZ), while manufacturer-led initiatives can provide discounts on new vehicles ranging from £1,000 to £5,000. 

Is the government car scrappage scheme still running?

No, the UK government does not currently offer a nationwide car scrappage scheme. The last national program ended in 2009, and there are no plans for a new one.

Since then, scrappage schemes have been localised or manufacturer-led, such as the options listed on this page. 

Do you need to tell the DVLA if you scrap your car?

You must tell the DVLA if you scrap your car so they can update their records. 

Once your car is scrapped or traded in, you should inform them using the V5C registration document. This lets them know the vehicle is off the road, and you’ll avoid fines for not keeping your details up to date!

A diesel scrappage scheme is key to making greener decisions, and hopefully, we’ll see more of these in 2025 and beyond. 

Keep learning about sustainable initiatives and the latest auto news today. 

Scrappage schemes can save you money, but they don’t help with pesky repairs.

If you own an MG ZS, you’ll know it’s a decent all-rounder – affordable, practical, and easy on the eye. But like all cars, it’s not without its quirks. When something starts making a weird noise or a warning light pops up, it’s always better to know what’s going on. So, here’s a quick look at some of the common problems of the MG ZS. 

For the most part, yes, the MG ZS is a reliable car. But it depends on how well it’s been looked after. If you’ve been keeping up with your servicing, using the right oil, and dealing with issues as they come up, you’ll likely have a good run with it.

But if your MG ZS has been skipping services or spending a bit too much time doing short, stop-start journeys, you might start noticing a few of the niggles that other owners mention.

Engine problems MG ZS drivers often report

The engine’s generally solid, but a few faults do come up. Here’s what people talk about most:

If your MG ZS has started feeling a bit sluggish, it might just need new air filters, an oil top-up, or a clean-out of the fuel system. Nothing dramatic, but worth sorting before it gets worse and you need to
