Are BMW cars reliable?

79.3%

MOT pass rate

vs 72.4% national average

BMW vs other premium brands

BMW vehicles pass their MOT at 79.3%, above the national average of 72.4%. Among premium brands, BMW sits mid-pack. Only Porsche breaks clear at 87.5%; Jaguar, BMW, and Audi cluster around the 78-79% mark.

The brand's reliability varies significantly by model and age. The i3, 2 Series, and X1 perform well above the BMW average. Larger models and older cars fare less well.

Reliability data shows part of the picture. A vehicle history check reveals the rest, including outstanding finance, stolen markers, write-offs, and mileage discrepancies.

What is the BMW MOT pass rate by age?

Pass rate at each vehicle age, from 3 to 20 years old. National average shown for comparison.

Newer BMWs (3 to 5 years old) pass at 87 to 89%, well above the national average for the same age range. The gap holds through the first decade of ownership. From around age 12 onward, the gap narrows but BMW pass rates remain above the national average at every age through to 20 years old.

The clear takeaway: BMWs age well relative to the market. Even at 20 years old, they pass at a higher rate than the average car of the same age, though reliability does decline steadily from around 10 years onward.

Top 5 specific BMW failure reasons

These are the specific MOT examiner findings most frequently recorded on BMW vehicles, along with what they mean.

Not working (6.73% of BMW failures)
A lamp, indicator, or electrical component that has completely stopped functioning. Usually a blown bulb or faulty sensor.
Damaged but not adversely affecting driver's view (6.24% of BMW failures)
Windscreen damage such as a chip or crack that has not yet spread into the driver's line of sight. Commonly caused by road debris.
Tread depth below requirements of 1.6mm (5.76% of BMW failures)
One or more tyres worn below the legal minimum tread depth. The legal limit is 1.6mm across the central three-quarters of the tyre.
Has a cut in excess of the requirements deep enough to reach the ply or cords (4.53% of BMW failures)
A deep cut or gash in a tyre's sidewall or tread that exposes the internal structure. Usually means the tyre needs replacing immediately.
Has ply or cords exposed (4.30% of BMW failures)
A tyre so worn or damaged that the internal cords are visible. This is a serious safety issue and an immediate MOT failure.

BMW's failure profile broadly matches the national pattern. Lamps and electrical equipment, suspension, and brakes account for the bulk of failures on both BMW and every other brand in the UK. Where BMW differs, the differences are small: a slightly higher share of suspension and brake failures, likely reflecting the heavier and more complex chassis of the range.

Which BMW models are most reliable?

Top 15 BMW models ranked by MOT test volume. Pass rate shown for each. Green bars beat the national average of 72.4%. Red bars sit below it.

Model	Tests	Pass rate	Most common failure
BMW 3 Series	311,206	72.5%	Lamps, reflectors and electrical equipment
BMW 118	135,399	78.8%	Lamps, reflectors and electrical equipment
BMW X1	94,713	81.9%	Tyres
BMW 116	89,865	72.1%	Lamps, reflectors and electrical equipment
BMW X3	79,492	79.0%	Lamps, reflectors and electrical equipment
BMW 1 Series	69,051	77.6%	Lamps, reflectors and electrical equipment
BMW X5	68,387	79.1%	Lamps, reflectors and electrical equipment
BMW 520	64,561	77.3%	Suspension
BMW 5 Series	64,492	83.4%	Tyres
BMW 420	54,847	82.3%	Tyres
BMW 218	41,327	80.8%	Tyres
BMW 320	35,839	85.7%	Tyres
BMW 120	34,517	71.3%	Lamps, reflectors and electrical equipment
BMW Z4	31,305	77.6%	Lamps, reflectors and electrical equipment
BMW I3	23,268	86.8%	Tyres

The BMW i3 and 320 are the top performers in this list, both passing above 85%. At the other end, the 116, 3 Series, and 120 sit at 71 to 73%, below the national average. The 3 Series is BMW's highest-volume model with over 311,000 tests, so its lower pass rate has a real impact on the brand's overall average.

How many miles do BMW vehicles typically cover?

Average recorded mileage at each MOT test, by vehicle age. National average shown for comparison.

BMW vehicles track close to the national average through their life. Younger BMWs (3 to 6 years) sit slightly above average, consistent with the executive-car and company-fleet profile of the brand. Older BMWs are broadly in line with the national curve.

Our Premium Vehicle Reports compare the recorded mileage at every MOT test to flag discrepancies. A drop in recorded mileage between two tests is a strong signal that the odometer may have been tampered with.

Are there any BMW safety recalls?

Safety recalls are issued by BMW when a manufacturing defect could affect the safety of the vehicle. The DVSA records every UK recall and links it to affected vehicle identification numbers (VINs). Recalls are free for the owner to have fixed at a franchised dealer.

Recall lists change over time as new issues are identified and old ones are resolved. For that reason we do not maintain a static list here. When you check a BMW via Brumble, the report shows any outstanding manufacturer safety recalls that still need action on that specific vehicle.

How do you check a BMW's full history?

Before you buy any used BMW, a full history check protects you from problems that a physical inspection would miss. Here is what a Premium Vehicle Report from Brumble covers.

Has this BMW been written off?

An insurance write-off means the car has been declared uneconomical to repair after an accident, fire, or flood. The report shows the category (Cat A, B, N, or S), the date, and the cause. Cat A and B are permanently unroadworthy. Cat N and S can legally return to the road but often carry hidden damage and are worth significantly less.

Is there outstanding finance on this BMW?

If the previous owner has an active HP, PCP, or loan agreement secured against the car, the finance company legally owns it until the balance is paid off. Buying a car with outstanding finance means the finance company can repossess it, even after you have paid the seller in full. The report checks with Experian for any active finance agreements.

Has this BMW been reported stolen?

The Police National Computer records stolen vehicles. The report checks the PNC for any active stolen marker. Buying a stolen vehicle means the police can seize it and return it to the rightful owner, with no compensation.

Has the mileage been tampered with?

Every MOT test records the current mileage. The report shows the full mileage history from every recorded test and flags any drops or unusually flat periods. A drop between tests is a strong signal the odometer has been clocked. A car worth £15,000 with 60,000 miles on the clock might be worth £10,000 if the true mileage is 120,000.

Has this BMW been used as a taxi or private hire vehicle?

Ex-taxis and private hire vehicles have typically covered high mileage under harder use than a private car of the same age. Insurers may view them as higher risk, and resale value is significantly lower. The report checks whether the vehicle has ever been registered as a taxi or private hire vehicle.

What is this BMW worth?

The report includes current trade, retail, and private-sale valuations based on the vehicle's make, model, trim, mileage, and condition. Use it to check whether the asking price is fair before you negotiate.
