Overall, the Mini Cooper brand is ranked 3rd in the subcompact car category by U.S. News Consumer Reports. It is generally considered a good car with a well-built engine, sporty handling, and an interior with all the bells and whistles.
But there are some common problems to look out for. Some of the most common Mini Cooper problems include:
- Clutch failure: On standard Minis, especially in cars made from 2002-2016, the clutch has been reported to wear out quickly, causing damage to the car’s transmission.
- Power steering pump failure: Cars made from 2002-2007 and 2012 have reported problems with Mini’s electro-hydraulic power steering system. Steering pumps in these cars often fail because of a faulty cooling fan.
- Automatic transmission failure: While this isn’t the most common complaint, it is one of the most costly to repair, and it happens enough to make the list.
- Water pump and thermostat housing leaks: First and second-generation Mini Coopers' use of plastic housings has led to leaks. Replace plastic housings as part of preventative maintenance.

Common problems by model
Now that you’ve seen the most common Mini Cooper problems, let’s take a look at some of Cooper’s popular models individually.
Most common Cooper S problems
Average annual repair cost: $846
CarComplaints.com complaints: 130
Do you hear a little rattling under the hood? The
Cooper S
is known for loose timing chains that require replacement. If the issue is ignored, the chain will break, which stops your car in its tracks and can cause major damage to your engine. Whether you have an automatic or standard transmission in your Cooper S, you may encounter issues with automatic transmission failure or clutch failure with a standard transmission. In either case, routine transmission maintenance can help.
Most common Cooper Hardtop problems
Average annual repair cost: $846
CarComplaints.com complaints: 108
Once your Cooper Hardtop gets over 50,000 miles, it is common to have leaks from the water pump or thermostat housing. Mini pros recommend replacing the pump and housing at 50,000 miles to prevent a more expensive and time-consuming repair down the road. Expect to spend about $200 on a
thermostat housing replacement
.The Hardtop is also known to experience similar issues with a loose timing chain and automatic transmission failure.
Most common Cooper Countryman problems
Average annual repair cost: $880
CarComplaints.com complaints: 19
Topping the list of unexpected and startling problems is the
Countryman
’s exploding sunroof. The 2013 Countryman had numerous reports of the sunroof unexplainably shattering while the car was being driven. Another common and unexplainable issue is with the 2011 Countryman’s brakes. This model tends to develop loud grinding noises that continue even when brakes have been newly replaced. This causes a lot of anxiety for Cooper drivers. If your
brakes are grinding
, make an appointment with your mechanic ASAP.Most common Cooper Clubman problems
Average annual repair cost: $484
CarComplaints.com complaints: 32
The
Clubman
shares many of the same transmission, fuel pump, and power steering issues as other Mini Cooper models. They also experience rear brake grinding noises, and problems with the automatic windows rolling up and then retracting a few inches on their own. If this happens to you, get a windows inspection
from your mechanic. Are Mini Cooper cars reliable?
When it comes to reliability, Mini Cooper is ranked 25th out of 32 car brands. Keep in mind that this score is based on the frequency of repairs as well as repair cost and seriousness of the issues.
The high cost of repair and maintenance for Mini Cooper has significantly hurt its reliability rating, especially when compared with non-luxury (and thus cheaper to repair) counterparts.
The least reliable model: 2005 Cooper S
Most common problem: Loose timing chain
NHTSA complaints: N/A
The 2005 Cooper S seemed to be the perfect storm of all the common Mini Cooper problems. When the second generation Cooper S was introduced in 2006, many of the original bugs were worked out to offer a better experience for drivers.
The most reliable model: 2021 Cooper Hardtop
Most common problem: Clutch failure
NHTSA complaints: 1
With the newest generation of Coopers on the market, drivers are experiencing common issues with much less frequency.
Cooper Hardtop models with a standard transmission still tend to experience early clutch failure, but overall the kinks have been worked out.
Still, elevated repair costs are a major influence on the Hardtop’s reliability ratings.

How long do Mini Coopers last?
With proper maintenance and responsible driving, you can expect to get an average of 200,000-250,000 miles from a Mini Cooper.
Taking preventative measures to replace the plastic thermostat housing, tighten the timing chain, and flush your transmission will help prevent some of the Cooper’s most common (and costly) issues.
Why is Mini Cooper unreliable?
The biggest factor in Mini Cooper’s reliability rating is the frequency and cost of repairs. As with other luxury vehicles, Mini Cooper is made for performance, style, and technology—but that doesn’t always translate to durability.
Luxury parts need to be replaced at luxury prices, so the Mini Cooper’s repairs can add up quickly.
