Is the 2021 BMW X3 recalled in the UK or Europe?
Recalls issued by the UK's DVSA and through the EU's Safety Gate system that cover this model and build period. European models can differ from U.S. ones, and "years estimated" means the recall gave no build dates, so confirm your own car with your registration or VIN.
UK DVSAReplace the Engine Starter Motor
Risk: The Safety Recall relates to the engine starter motor. The fault relates to the RSW22 starter RWT (reinforced water tightness). It was found that with RWT starters an increased abrasion of the magnetic contact can cause the growth of deposits at the lowest point of the relay interior. This in turn may increase the relay contact resistance resulting in false starts or even causing short circuits and possibly a thermal reaction. In case of a short circuit the possibility of a thermal event cannot be excluded. This may happen while attempting to start the vehicle or while driving due to vibrations causing a short circuit due to moving deposits.
Fix: On the affected vehicles the starter motor will be replaced with a variant by another supplier with a different design. Until the repair has been completed it is recommended to not leave the vehicle running unattended after starting the engine.
UK DVSAReplace the Engine Starter Motor
Risk: For affected vehicles there is a concern involving water ingress and corrosion to the starter motor for where a short circuit cannot be ruled out. It is strongly recommended to park the vehicle outdoors and not in the immediate vicinity of buildings until the repair has been carried out.
Fix: Replacement of the starter motor.
UK DVSALuggage Compartment Lashing Rail G01 F97
Risk: On affected vehicles the screw connection for the luggage lashing rails may not withstand the forces in situations of a rear end impact. This may result in the lashing rail to not crumple as expected in these situations.
Fix: On affected vehicles the luggage lashing rail screws will be replaced with revised screws.
UK DVSALuggage Compartment Lashing Rail G01 F97
Risk: On affected vehicles the screw connection for the luggage lashing rails may not withstand the forces in situations of a rear end impact. This may result in the lashing rail to not crumple as expected in these situations.
Fix: On affected vehicles the luggage lashing rail screws will be replaced along with additional washers.
UK DVSAOn affected vehicles the bolted connection to the starter-generator may not have been tightened according to specifications.
Risk: On affected vehicles the bolted connection to the starter-generator may not have been tightened according to specifications.
Fix: Check and rework the ground connection to the starter generator if required.
UK DVSAThe affected vehicles possibly have an inadequate laser weld seam on the seat mechanism/frame of the driver s or front passenger seat.
Risk: The affected vehicles possibly have an inadequate laser weld seam on the seat mechanism/frame of the driver's or front passenger seat.
Fix: Replace the defective seat mechanism and backrest frame on the affected front seat.
UK DVSAUndetected EGR System leaks may cause thermal activity in the intake manifold
Risk: Undetected EGR System leaks may cause thermal activity in the intake manifold.
Fix: The engine management control unit (DDE) will be programmed with improved software incorporating the latest OBD functionality.
UK DVSAThe exhaust gas recirculation cooler may leak over time and cause thermal incident
Risk: The Exhaust Gas Recirculation cooler may leak over time and cause thermal incident.
Fix: On the affected vehicles the EGR cooler module will be replaced.
UK DVSAThe battery cables on the 48v starter generator may not have been sufficiently secured during production
Risk: The battery cables on the 48V starter generator may not have been sufficiently secured during the production process.
Fix: Check the screw connection of the 48V positive / negative battery cables on the starter generator and rework if necessary.
UK DVSARemaining particles in the cells of the high voltage battery can cause a short circuit
Risk: A possibility of impurities contained in the HV batteries may cause short circuit.
Fix: Testing of battery charge cycles and replacement of the HV cells where necessary.
UK DVSAOn affected vehicles seat belt mounting bolts may not be securely attached
Risk: On affected vehicles seat belt mounting bolts may not be securely attached.
Fix: Check connections of both front seat belts and rework if necessary.
EU Safety GateThe RSW22 starter with reinforced water tightness (RWT) may experience increased abrasion of the magnetic contact, causing deposits to…The RSW22 starter with reinforced water tightness (RWT) may experience increased abrasion of the magnetic contact, causing deposits to build up at the lowest point inside the relay. These deposits may increase relay contact resistance, leading to starting failures or short circuits. If a short circuit occurs, either when attempting to start the vehicle or while driving due to vibration-related movement of the deposits, it could cause a thermal event and increase the risk of fire.

(NHTSA complaint 11726141, March 2026). Recall repairs are free at a dealer; check your VIN at nhtsa.gov/recalls.
Check your own X3
Counts are a starting point, not a verdict: popular models collect more complaints because more of them are on the road, and NHTSA does not verify individual reports. To see whether a recall is still open on your car, enter your VIN at nhtsa.gov/recalls (U.S.) or your registration at check-vehicle-recalls.service.gov.uk (UK). Had a safety problem? Report it to NHTSA; complaints are what trigger investigations and recalls.
