Why 24,732 BMW Owners Are Being Warned About a Fire Risk Under Their Bonnet

BMW has issued a formal safety recall covering 24,732 cars in the United Kingdom due to a manufacturing defect in the starter motor that could, in the worst case, cause a vehicle fire. The recall, registered with the Driver and Vehicle Standards Agency, affects 11 different BMW models built between July 2020 and July 2022. Globally, the recall covers an estimated 575,000 vehicles. If you own one of the models listed below and it was built in that window, your car may be among those affected.

The DVSA operates a free online recall checker at gov.uk/check-vehicle-recalls. Entering your registration number takes under a minute and tells you immediately whether your car is subject to an open recall. BMW is also contacting affected owners by post, but if you have recently moved or changed contact details, do not wait for a letter.

Which BMW Models Are Affected and How to Check

The recall covers BMW cars manufactured between July 2020 and July 2022 across the following model codes: the 2 Series Coupe (G42), 3 Series Touring (G21), 4 Series Coupe (G22), 4 Series Convertible (G23), 4 Series Gran Coupe (G26), 5 Series Saloon (G30), 5 Series Touring (G31), 6 Series GT (G32), 7 Series (G11 and G12), X3 (G01), X4 (G02), X5 (G05), X6 (G06) and Z4 (G29). That is a broad spread across BMW’s range, taking in family estates, executive saloons, SUVs and sports cars from those model years.

In plain registration terms, that generally means cars carrying a 20, 70, 21, 71 or 72 plate. A car registered between March and August 2020 carries a 20 plate, between September 2020 and February 2021 a 70, between March and August 2021 a 21, between September 2021 and February 2022 a 71, and between March and August 2022 a 72. If your BMW sits within those years and matches any of the model types above, enter your registration at check-vehicle-recalls.service.gov.uk or check BMW’s own recall lookup page at bmw.co.uk.

What the Technical Fault Actually Does

The problem lies in the magnetic switch inside the starter motor. BMW describes the defect as a manufacturing issue that causes the switch to wear at a higher rate than normal. Once the switch wears sufficiently, a short circuit can occur. That short circuit causes localised heat to build up around the starter motor assembly, and in a worst-case scenario the heat becomes severe enough to cause a fire under the bonnet.

The starter motor is engaged every time you start the engine. On a petrol car, this happens when you press the start button or turn the ignition key. On mild hybrid variants within the affected range, the starter-generator unit also supports energy recovery and provides additional torque functions, meaning it may operate more frequently than a traditional starter and could wear faster. BMW says affected owners may notice a smell of smoke while driving or, more commonly, after they have parked and walked away from the vehicle. The risk of fire after the engine is left running unattended is the principal concern.

It is important to understand that not every affected vehicle will develop this fault. The defect creates a risk rather than a certainty. BMW identified the issue during internal quality control reviews and acted proactively before widespread incidents were reported. That said, the consequences of a starter motor fire are serious. This recall sits alongside other recent safety notices affecting UK drivers, including the 44,000-vehicle Stellantis recall over engine fire risk and the three new DVSA recalls affecting 40,000 UK cars registered in May.

What BMW Is Telling Owners to Do Right Now

BMW’s immediate safety advice to owners of affected vehicles is specific: do not leave the car running unattended. That means not warming the engine on a cold morning while you go back inside, not leaving it idling in a car park while you load shopping, and not using remote start features that keep the engine running without you present. This interim measure reduces the risk while you wait for your recall repair appointment.

The manufacturer is working through its authorised dealer network to contact affected owners by post. Letters include instructions on how to book a free repair appointment. The fix involves inspecting the magnetic switch inside the starter motor and, where the defect is identified, replacing the switch. BMW says the repair typically takes around 30 minutes per vehicle and there is no charge to the owner whatsoever. Courtesy cars or a collection and delivery service may be available depending on the dealership, so it is worth asking when you call to book.

If your BMW was purchased on a finance agreement, the recall remains your responsibility to arrange. Leaving a known safety defect unaddressed could affect your insurance position if an incident occurred and an insurer discovered an open recall had not been resolved. This applies whether you own the vehicle outright, hold it under a personal contract purchase or lease it under a personal contract hire arrangement.

How to Book Your Free Repair and What Happens If You Do Not

The quickest check is the free government recall database at check-vehicle-recalls.service.gov.uk. Type in your registration number and the DVSA system returns any open recalls registered to that vehicle. The check covers all manufacturers and all current UK recalls, not just BMW. It takes under two minutes and requires no account or registration.

Alternatively, call your nearest authorised BMW dealership with your Vehicle Identification Number (VIN). The VIN is a 17-character code stamped on a plate visible through the base of the windscreen on the driver’s side, and is also printed on your V5C registration document. The dealership can cross-reference the VIN against the recall register and book a repair slot. BMW’s own recall lookup tool at bmw.co.uk also accepts VIN numbers directly.

If you cannot get through to a dealership quickly, the DVSA recall helpline is available on 0117 866 8009, Monday to Friday from 7:30am to 6pm. The helpline can confirm whether your vehicle is affected and, in cases of difficulty booking a repair, assist with escalation.

If you have recently bought a used BMW in the affected model year range, check immediately regardless of what the previous owner told you. A recall attaches to the vehicle’s VIN, not to any particular owner. A change of ownership does not close an open recall. Sellers are not legally required in the UK to disclose open recalls before a sale, so it is always worth running the check on any used car you are considering purchasing. For a broader picture of your rights when a recalled car causes an incident, the Citizens Advice consumer helpline at 0808 223 1133 can provide guidance specific to your circumstances.
