As the replacement for the formidable 190 in 1993, the C Class had a lot to live up to, especially in the reliability stakes. Early cars enjoyed the same reverence, but does the current generation have the same bulletproof reliability?

In this article, we’ll take a look at the C Class’ weak points, any manufacturer recalls that have been issued, and ultimately, if they’re worth buying.

In 2024, Mercedes as a brand placed 22nd out of 31 manufacturers. This makes them statistically less reliable than most other luxury marques, including Lexus, BMW, Audi and even Skoda. The 2014 - 2021 C Class placed 14th out of 20 cars in WhatCars? reliability rating, and the current one was given a 6.8/10 score by MotorEasy for reliability.

Whilst most of the faults were covered by Mercedes’ warranty, it’s difficult to give too much praise to the C Class’ reliability based on the figures alone.

Recalls are issued by the manufacturer when a defect with the design or manufacturing of the car is noticed, especially one that affects the vehicle's safety. Recalls are always repaired by the dealer, free of charge. 

It's easy to double-check if your car is affected by any outstanding recalls with the 

Worryingly, the current generation of C Class has quite a few recalls in the short time it's been in production; 38 to be exact. Whilst some of these are for software and minor things, such as an incorrect sticker fitted, many do involve serious safety features of the car.

The behaviour of the emergency call system might not meet expectations

No extra detail is given regarding this recall issue, just that the fix involves a software update to the communication module. This is the part of the system responsible for the emergency call system, should a car be involved in an accident. 

By my calculations, taken from data just pertaining to the non-AMG version of the C Class built in 2021, nearly 420,000 cars had this issue. It might not be a case of finding a car that has had the issue rectified, but if Mercedes has time to repair all the affected cars!

Inside the fuel pump is a small blade called an impeller that spins at high RPM to deliver fuel to the engine. On certain models made in 2021, this can deform under load and stop working effectively. 

The issue affected just over 1,000 cars, and the remedy is the replacement of the fuel pump. 

On around 800 cars, an issue was detected relating to the front passenger airbag, and its effectiveness when needed in an accident. The repair involves the replacement of the airbag at a Mercedes dealership.

These are issues that are reported by multiple owners; they don’t necessarily indicate lots of cars will have problems, just that these are the ones you are most likely to encounter.

It's easy to find many owners discussing problems related to the emissions system, specifically the AdBlue injectors and tank. The urea-based fluid can crystallise in the system if certain conditions are met, often resulting in needing a new injector - these can be very expensive.

It’s unclear if these problems are through a design or manufacturing fault of the car, or if the owners are not using the vehicle as intended - i.e. running a diesel only on short journeys, or forgetting to fill the AdBlue tank.

A common fault on the previous generation of C Class, is faulty door mirrors. The folding mechanism uses a motor inside the mirror and sensors to detect when it’s folded or unfolded. These become noisy and weak over time, resulting in mirrors not fully opening or closing.

To replace the mirrors with new parts can cost an arm and a leg (some sources state £500+ per side), so make sure to listen carefully when looking at a used C Class. 

The 7G-Tronic automatic gearbox used on certain C-Class models is great, providing fast, smooth changes and high efficiency. It is however, a complex system, and needs routine maintenance to ensure it works correctly. 

A G-Tronic gearbox that has been neglected could leave you with some big repair bills if it goes wrong.

Mercedes C Class Reliability Guide

Whether it's a low-speed scrape in a car park or a surprise knock from a rogue bollard, bumper damage can be frustrating and expensive. But here’s the good news: you don’t always need to replace your bumper; sometimes it just needs a quick repair. Let’s see what affects bumper repair costs, what your choices are, and how to make paying for repairs easier with Bumper’s 

How much will it cost to repair a bumper?

The cost of fixing a bumper in the UK depends on a few key things: the type of damage, the make and model of your car, and whether you go for a replacement or repair.

Luxury cars and specialist paints can push these numbers higher still, but if the damage is mostly cosmetic, you’re likely looking at a relatively low cost.

In many cases, yes, it’s worth getting your bumper repaired. If the structure is intact and the damage is mostly surface-level, a skilled technician can fix cracks, fill dents, and repaint it without needing to replace the entire bumper.

Bumper damage can knock hundreds off your car’s resale value. Even small scuffs can make potential buyers wonder what else has been neglected.

Worse still, cosmetic damage can expose your car to rust or structural issues over time. In other words, try seeing it as a way of retaining your car’s value when it comes to selling – not doing so could have a big impact on your car’s final price.

What does bumper repair cost in the UK?

The 1 Series was launched in 2004 as the German brand's smallest and cheapest car. It was, however, immediately considered the premium option in the segment, an honour it still holds today. Buyers loved the great handling, much of it shared from the 3 series, and the compact practicality of a hatchback. 

It went from strength to strength, with its popularity never really waning. However, did the 1 series inherit the same German engineering as the larger cars, and are the newest models as reliable as you’d hope?

With a reliability rating of 97% from WhatCar? Magazine, it's safe to say the current generation is pretty reliable. Only 15% of cars involved in the test reported any faults, with 40% of these being fixed for free by BMW, in a day.

As a brand, BMW finished 12th out of 31 manufacturers, placing above the other big German brands: Audi, VW and Mercedes-Benz. 

When a car develops a fault, particularly a safety-related one, the manufacturer will issue a recall, encouraging all owners to bring their car back to the dealer for the issue to be fixed, free of charge. 

You can do a search of what recalls affect your vehicle on the 

, either by searching by make and model, or by number plate. Reassuringly, the 1 Series has very few recalls, and most only affect a small number of cars. 

Camshafts are what open the valves of an engine, allowing the fuel to enter and the exhaust gases to escape. They are driven by the 

, and have bearings to enable them to rotate efficiently.

On a very few cars made in 2021 – 38 to be exact – these bearing holders were not installed correctly. This requires either new bearings, or a new cylinder head – a major engine component – presumably depending on the amount of premature wear the issue has caused. 

A slightly more prevalent issue, affecting just over 1,100 cars, is one relating to the driver's airbag and the design of its cover. The recall wording states that the fabric of the airbag itself could be damaged by the cover upon deployment - a serious issue in the event of a crash.

The issue affected cars made in 2020 and requires a new airbag to be fitted at the dealership.

Incorrect screw material on the rear seat belts

On 38 cars made in 2021, some of the screws used to fasten in the rear seatbelt assembly were not of an acceptable grade material. The remedy is to simply remove and replace the screws with ones of superior quality.

All cars have common faults, be it a design fault, or a weakness that becomes apparent after a certain amount of time and miles. It doesn’t necessarily mean the cars are unreliable, but it does highlight something to look out for should you be buying secondhand. 

A number of owners have complained about issues with incorrect or intermittent dashboard lights on their current generation 1 Series. It’s not clear if this is a sensor problem, an issue with the ECU/wiring to it, or a problem with the dash module itself. 

Many owners reported needing multiple trips to the dealer for software updates and reboots, though the dealership experience was positive for most.

While the previous generation of 1 series was well-famed for its reliability, there is one issue that gets mentioned a lot online, that is, the washer jets becoming blocked all too frequently. 

This is generally resolved by removing them and cleaning through with a narrow cleaning tool, but is not something you’d expect on a BMW, only 5 or so years old!

Because the older generation 1 series is fitted with the same complex type of suspension found in the larger 3 series, owners found their cars consumed suspension bushes and joints faster than they expected. 

Whilst the wear was probably not more than typical for this type of suspension, other cars in the segment use less refined but less complex systems that are more robust at high mileage.

BMW 1 Series Reliability

First introduced in 1975, the 3 Series is one of BMW’s most popular models. The current generation, the G20 model unveiled in 2018, continues with the same recipe: comfort, driving performance and rear-wheel drive. 

However, with cars becoming more and more complex, is the 3 Series as reliable as we’ve come to expect from BMW? We’ll take a look at some common problems, recalls and discuss if the 3 Series is a good buy in 2025.

The petrol and PHEV versions of the latest 3 Series ranked 2nd in the executive class with a 97.5% reliability score in the 2024 WhatCar? survey, while diesels achieved around 96%. BMW as a brand scored 8th out of 31, which is pretty good!

According to the same WhatCar? survey, the most commonly repaired fault related to the engine or electrics, but BMW paid for 96% of the repairs needed, and fixed nearly 70% of faults in less than a week.

There have been a few recalls on the 3 Series since its launch in 2019; thankfully, any recall work is to be completed by the manufacturer, free of charge. Check to see if your car, or one you're looking at buying, has any outstanding recalls 

On certain vehicles built between 11 March and 9 July 2019, a bearing bushing was not properly installed into the engine's crankcase, whilst only a small part, it requires the engine to be removed and potentially replaced - it’s a good job, recall work is paid for by the manufacturer! 

Even though only 53 cars were affected, it's still worth double-checking any potential car, as the fault can lead to engine failure, which will be extremely inconvenient even if the repair cost is covered!

Certain 3 Series models (made from March–September 2020) had battery pack debris left from welding that could cause short circuits. Affected units may need battery replacement.

Symptoms of this fault could be quite severe, so it’s important to get your car checked. 

’s cooler system may develop a leak. The type of coolant used, mixed with sediment from the EGR system, can cause “ignitable” deposits. 

If your 3 Series was made in 2018, this one is definitely worth checking, as it affected nearly 64,000 cars.

Suspension components rank among the most frequent repairs. Symptoms include uneven ride, steering pull, or audible knocking when braking. This could also be related to the poor condition of UK roads and the G80’s firm suspension.

Fixes include general suspension replacements, such as shocks, suspension arms and bushes.

Many UK owners report occasional iDrive bugs, Bluetooth dropouts, and touchscreen unresponsiveness, which is something we see across all makes and models of modern cars.

Typically, a software update is needed from the dealer, but these things can also be remedied by a system reboot.

Electrical issues include warning lights without a clear cause, central locking or body control faults. A forum post advising people to check battery ground wires got a bit of attention, indicating there are a few common electrical issues.

Despite the few ‘common’ faults listed above, the 3 Series seems to be a very well put-together car. It also receives lots of praise for its driving characteristics, and achieved an impressive Euro NCAP score. 

Residual prices of most BMW models are also strong, which is usually a good indicator of a brand's overall reliability; it also helps with depreciation come trade-in time.

Overall, if you are happy with the slightly elevated repair costs associated with German marques, and the few niggles listed above don’t put you off, the 3 Series is a perfect executive saloon.

BMW 3 Series Problems/Reliability Guide

The Polestar 2, promises Scandinavian design, thrilling performance, and a tech-first experience. But as an early-generation luxury EV, it comes with some minor issues.

This guide explores reliability ratings from independent surveys like What Car?, common problems from real-world owners, and important recall information to help you make an informed decision.

What Car?’s 2024 reliability survey ranked the Polestar 2 10th out of 20 electric cars with a score of 89.3%, placing it favourably ahead of models like the Kia EV6 and Porsche Taycan, though behind the Tesla Model 3. 42% of owners reported issues, mostly related to infotainment and electrical systems—but almost all were remedied swiftly and under warranty.

Auto Express’ Driver Power survey ranked the Polestar brand 2nd overall in 2023. The Polestar 2 model itself came 17th out of 75 but 69% of first-year owners reported faults, resulting in a poor 71st-place in reliability rankings.

Recalls are manufacturer-led responses to a common and premature fault on a vehicle; it can be on any part of the car, but they are most often issued when it affects the safety of the vehicle. 

Recalls are fixed by the manufacturer at no cost to the owner/driver of the car. To see if your vehicle is affected, check the 

Inverter Capacitor Terminals Causing Short Circuiting

The terminals of the capacitors found in the inverter module are plated with a tin-coating, likely to reduce electrical resistance. On some models, this plating was found to be defective and could cause short-circuiting or other issues with the inverter. 

This was leading to driving issues and warning lights on the dash. The fix involves replacing the inverter module with a non-affected one. Just under 700 cars were affected, and were all made in 2020. 

On nearly 2,400 cars made in 2021, an issue with the contactors in the battery energy control module. The issue seems to be from the car's software, as the solution to the recall is to update it at the dealership. 

Symptoms of the issue are unexpected and unintentional losses in power, accompanied by warning signs and lights on the dashboard. The fix is free of charge and carried out at a Volvo or Polestar dealership.

One of the most commonly reported issues from UK owners is frequent infotainment glitches, such as touchscreen freezes, audio drop-outs, and system resets. Seemingly, some owners have remedied the fault with a system reset, but others needed intervention from the dealership.

Even after a dealer software update, some owners reported repeated faults occurring.

Similar to the above, another common issue is faults with the antenna module. This connects the car to the internet and, therefore, the Polestar service centres. This means functions such as app control, eCall, GPS, and digital key stopped functioning.

Thankfully, many owners reported that having the module replaced by the dealership solved the issue, so it might be a faulty batch/software version.

Some UK reports echo early shutdowns and limp-mode errors, often requiring recovery services. These may or may not be related to some of the above-mentioned recall issues.

 sudden loss of power from the motor, “Propulsion System Service Required”, and warning lights on the dashboard. Some owners have said that a software update from the dealership helped.

Owners have noticed knocking or clunking noises from the front suspension, especially during braking or on uneven surfaces. Members on a Polestar forum discussed a service bulletin that was issued to replace the strut bearings with upgraded parts. 

It is unclear if this same bulletin was issued in the UK, and if that is the cause of some of the problems, but be sure to keep a lookout for any test drives, and get the seller to sort the issue before you purchase the car.

Data shows mixed reliability. While it’s technologically advanced, fun to drive, and well-appointed, issues with electronics, connectivity, and drivetrain errors are common, especially in early models. 

That said, most of the issues from earlier cars should be ironed out by now, and the later cars seemed to fare much better, making the Polestar 2 a compelling choice. 

Polestar 2 Problems / Reliability Guide

Almost all vans are bought primarily as a tool, a device to get people, materials and tools to and from a job site. Even a quickly-repaired breakdown can cost thousands of pounds in lost work and missed deliveries. That’s why we’ve put together this list of the most reliable vans currently available in the UK.

Many of these long wheelbase vans have a load length of over 4m, and can be specified with the high roof, giving an enormous amount of room. 

The Sprinter is considered the gold standard for LWB vans, with its dependable 2.0 diesel engine and over 1,200kg carrying capacity. In 2024, the Sprinter made no.2 on the most reliable van list, the first time in a decade it didn’t win 1st place!

If diesel feels a little old-fashioned for you, Mercedes offers a fully electric version, with up to 272 miles of range from its 100 or 150w motor. Need even more hauling capacity? The EV version of the Sprinter can tow a 2,000kg trailer, too.

Alongside the Sprinter, the Transit is one of the most common LWB vans in use on UK roads. Between the options of wheelbase, height and bed type, and drivetrain, there are dozens of options available for the Transit, so there’s sure to be one to suit your business’s needs. 

Now available with an 8-speed automatic transmission, replacing the old 6-speed unit, but most are likely to be optioned with the traditional 6-speed manual. 

In addition to the two above, which are also available as short-wheel-base versions, these vans are medium-sized panel vans that give a large amount of space, whilst being easier to park. They are a favourite of tradies and those looking to build a campervan.

In 2024, the Transporter took the top spot for reliability from the Sprinter, in a bold move from second place for a number of years. Its reliability is said to stem from its dependable time-served diesel engines and robust build quality. 

The Transporters of 2025 and onwards will be replaced with badge-engineered Ford Transits, which typically place much lower, so be quick to buy if you’re set on a VW.

Inside the van, the VW has everything you can expect in a modern commercial vehicle, DAB and electric windows as standard, with a whole host of additional safety and convenience features on the higher trim levels. 

As it’s been on our roads now for nearly 25 years, the Vivaro is almost as well-known as the Transit for being a tradesman's van of choice. Since 2019, Vauxhall's partnership with Renault ended, and the new vans were based on a Stellantis design, being shared with 4 other marques.

Despite this cost-cutting measure, the Vivaro still regularly places around 5th in the reliability rankings, strangely 4 places above one of its sister vehicles, the Toyota Proace. Despite the new design looking slightly smaller than the old one, the Vivaro can carry an impressive 1,384kg, and has a choice of two diesel and one electric powertrains.

These small vans are ideal for those needing a dedicated cargo area, but without the need to carry particularly long or large items. Often using the engines and suspension setups from medium-sized passenger cars, they tend to drive better than larger vans, too. 

Landing at number 3 on Fleet News’ reliability ranking, the Caddy is just as reliable as its bigger brother, the Transporter. The current model, released in 2021, is based on the current model of Golf, meaning it offers great ride quality and comfort. 

Payload weight is limited, at only 780kg, but the clever floor design gives a very low floor in the back, making it easier to load heavy items by hand. From the driver's seat, it’s hard to tell you’re in a van, with premium materials, an appealing steering wheel and a usefully large infotainment screen. 

Ford Transit Connect - from £23,500 + VAT

Launching in 2021, the current generation of Transit Connect is a re-badged Volkswagen Caddy, another aspect to the Ford-VW deal we discussed earlier. Styling is, therefore, very similar, with the two being almost indistinguishable from the rear.

This means the new Connect has roughly the same load area, payload and specs as the Caddy, although it is a little cheaper to purchase. One notable difference is the presence of a plug-in hybrid option for the Connect, which is not offered alongside the VW-badged van - something to consider.

QUIZ TIME: Guess the car from the car part

Until a few years ago, the only place you’d see a pickup truck in the UK was on or near a farm. But since various manufacturers started making them more luxurious and comfortable, and their tax status has made them very attractive to business owners, they have exploded in popularity. 

That tax situation has since changed, with double-cab trucks now being classified the same as private vehicles, but this just means the market is great for private buyers. Here are some of the best pickup trucks on sale today. 

Heralded as one of the most reliable vehicles of all time, in part thanks to a classic Top Gear episode, the modern Hilux is a capable, 1-ton carrying pickup that has all the bells and whistles of many modern SUVs. 

The current new model was facelifted in 2020, but has been using the same drivetrain and chassis since 2015, meaning parts should be easily accessible, and the drivetrains and design well tested. It’s available with a 2.4 or a 2.8-litre diesel engine, and can tow 3,500kg.

Its load bed is 1555mm long, which is decent, but not class leading. The Ford Ranger beats it by over two inches, but the Isuzu D-Max extended wheelbase is the truck to get for load bed length at over 1800mm.

The Ranger is one of the UK’s most popular pickups, well reviewed both as a comfortable cruiser and a useful work vehicle. There are quite a few engine options available, ranging from a modest 170hp diesel, up to the most powerful version - the plug-in hybrid. This offers nearly 300hp and an electric-only range of 26 miles. 

The current shape of the Ranger is clearly inspired heavily by the American versions, with large chunky bumpers and quietly flared arches. Something particularly impressive is the generator function of the PHEV Ranger. A standard 3-pin socket in the bed allows the use of small hand tools and charging of power tool batteries.

The astute driver would probably notice that the Amarok is very similar to the Ford Ranger in power and driving dynamics, because they share the same underpinnings. Despite VW’s success with the first-gen Amarok, they paired with Ford to cut costs on the development of the new one - this isn’t a bad thing, though. 

Despite the underneath being similar, the body and interior of the Amarok are completely different. The front and rear aspects are decidedly Volkswagen, with the grille lines blending into the headlight shape. 

Inside, the Amarok features a few more steel-edged controls and leather coverings than the Ranger, but they’re both clearly well-thought-out products. Unsurprisingly, the bed length is around the same as the Ranger at 1600mm give or take. Its carrying capacity is 1130kg.

Unlike the rest of the cars on this list, Isuzu don’t make any passenger vehicles anymore, focusing solely on commercials and pickup trucks. This makes sense when you look at the base “utility” version of the D-max. That said, the DL20 model being discussed here is very much a player in this SUV-like Truck sector.

This is mainly due to its alloy wheels, Apple CarPlay with an 8” touchscreen and a plethora of assist features like a reversing camera, cruise control and tyre pressure monitoring. It still maintains usability, though, especially the extended model with its 1800mm bed length.

The T90EV is currently the only fully electric pickup sold in the UK. It has a claimed range of 200 miles and around 200hp from the single, rear-mounted electric motor. Ride comfort and handling are described as not as good as the competition, but the feature list is reasonably long with things like a backup camera and a large infotainment screen. 

The bed is a reasonable length at 1,485mm and can take a one-ton payload. One of the upsides of having a pickup truck over a van is the off-road capability - unfortunately, due to the T90EV’s rear wheel drive and lack of ground clearance, it’s probably best kept on the road.

A rebrand to KGM should help the Ssangyong’s image, as some may remember previous vehicles such as the Rodius, as being not particularly good or easy on the eye. The New Musso truck, however, is not too bad to look at and comes with some impressive features, for the price. 

The long wheelbase version has a bed of around 1,300mm in length, and can carry over 1,200kg. Inside, there is an infotainment screen, but smaller than those found in the Ranger, etc, flanked by physical buttons, something that could actually be an upgrade, especially for a work truck. 

Once you're sorted and on the road with your pickup, it's essential to keep your new vehicle in top shape with regular maintenance. Thanks to Bumper's
