BMW X5 Reliability by YearBest & worst years, problems & recalls — NHTSA data

The contact owns a 2021 BMW X5. The contact stated that while driving at an undisclosed speed, the air bag warning light unexpectedly illuminated. The vehicle was taken to the dealer where it was diagnosed that the air bag had failed and that the air bag and/or the sensor needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA hotline for further assistance. The failure mileage was approximately 63,382.

Front Differential - Repair/Replacement on 2021 BMW X5 M50i. Extreme safety issue. Ironically failed right after 50k warranty. Currently at 50742 miles. Brought vehicle in 6 different occasions in the last year and a half. One time for a similar issue (approx. 1 year ago) and instead of addressing the problem at the time they just replaced the transfer case, masking the root issue and pending complete failure of the system.

Water pump failed while driving on highway. Completely shut down and began to smoke violently. Luckily wife was able to pull over immediately without crashing. Wife and children very disturbed. Looked up issue and 720000 BMW x5 have been recalled with same exact issue. Ours is not. Why?????

The original B58 engine (B58B30M0, 2015–2017) utilized a conventional mechanically robust gerotor oil pump with predominantly metallic internal construction and demonstrated strong reliability in field operation. Beginning with the B58 Technical Update introduced for 2018 production (B58B30O1), BMW redesigned the lubrication system by integrating the engine vacuum pump and oil pump into a combined variable-displacement assembly. This redesign introduced a thermoplastic internal adjusting ring (carrier) responsible for regulating oil pump displacement through rotor eccentricity control. This component, constructed from reinforced thermoplastics including PA66-GF materials, operates within a chemically aggressive and thermally cyclic environment involving continuous exposure to engine oil additives, fuel dilution, condensation, and repeated heat cycling. While acceptable under accelerated validation testing, real-world operating conditions increasingly demonstrate premature degradation consistent with polymer embrittlement and fracture. Observed Failure Mode Documented owner and technician reports indicate that under cold-start conditions — particularly in sub-freezing climates — elevated oil viscosity and startup load impose increased mechanical stress on the thermoplastic carrier. Fracture of this internal component allows debris intrusion into the pump mechanism, resulting in unstable oil pressure regulation. Commonly reported precursor symptoms include: • Inability to perform electronic oil level measurement via iDrive • Erratic or oscillating oil pressure behavior • Intermittent lubrication warnings or absence of warning prior to failure • Rapid progression to bearing damage and engine seizure In many cases, drivers receive insufficient warning before catastrophic lubrication loss occurs. Vehicles may become disabled without notice, including during highway operation or winter driving conditions, leaving occupants stranded in potentially dangerous environ

The contact owns a 2021 BMW X5. The contact stated that while starting the vehicle, the Push to Start button failed to function as intended. After several attempts, the vehicle started. The drivetrain warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed, and determined that the starter had failed and needed to be replaced. The dealer informed the contact to cease driving the vehicle due to safety concerns. The vehicle was not yet repaired. The vehicle remained at the dealer unrepaired. The manufacturer was notified of the failure. The failure mileage was 47,600.

The contact owns a 2021 BMW X5. The contact stated that while driving at an undisclosed speed on the highway, the vehicle shut off. The vehicle was pulled off to the side of the road, but failed to restart after several attempts. The vehicle was towed to a local dealer, where it was diagnosed with starter failure. The dealer referenced NHTSA Campaign Number: 20V761000 (ELECTRICAL SYSTEM); however, the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 30,000.

the vehicle delays to start and will not recognize that key is in the vehicle. the starter button has to be pushed three times until the vehicle recognizes the key is in the vehicle. the vehicle was inspected at a BMW dealership and no codes or errors were found. battery is still good but possible issues with the starter.

The contact owns a 2021 BMW X5. The contact received notification of NHTSA Campaign Number: 24V608000 (ENGINE AND ENGINE COOLING, ELECTRICAL SYSTEM); however, the part to do the recall repair was not yet available. The contact stated that the VIN no longer showed the recall as being open. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

The contact owns a 2021 BMW X5. The contact stated that while attempting to start the vehicle with the Push to START button, the vehicle failed to start. There was a clicking sound coming from under the hood. The failure was intermittent. The contact replaced the hybrid battery; however, the failure reoccurred. The contact stated that after several attempts, the vehicle started. The vehicle was taken to a dealer; however, the failure was not duplicated. The vehicle was taken to an independent mechanic, where it was diagnosed with a pinned-out emission circuit and starter failure. The contact was informed that the starter needed to be replaced. The vehicle was not repaired. The contact was informed of an unknown recall; however, the VIN was not associated with the recall. The vehicle was manufactured a month outside the date for the vehicles included in the recall. The contact was advised to contact the manufacturer and make the manufacturer aware of the failure. The manufacturer was made aware of the failure. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 60,000.

The contact owns a 2021 BMW X5. The contact stated that while driving at undisclosed speeds, unknown warning lights illuminated on several occasions. The failure had occurred while driving and while restarting the vehicle. The vehicle was taken to a dealer, where it was diagnosed, and determined that the starter had failed and needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for further assistance. The approximate failure mileage was 44,000.

I am writing to formally file a complaint and request an expansion of recall coverage regarding a starter motor failure on my 2021 BMW X5, which occurred at approximately 38,000 miles. Recently, my vehicle experienced a sudden failure to start. After inspection, the issue was diagnosed as a starter malfunction. I am aware that BMW has issued a recall addressing starter-related defects for certain vehicles of the same model year and configuration. However, I was informed that my vehicle’s VIN is not included in the current recall list. Given the relatively low mileage, the nature of the failure, and the existence of an official BMW recall for the same defect, I believe this issue represents a manufacturing or design defect rather than normal wear and tear. A starter motor failure at 38,000 miles is both unexpected and unacceptable for a premium vehicle such as a BMW X5

In the middle of driving, multiple warning lights came on in the car and the steering became very stiff, which made it difficult to steer the car. We brought the car to the dealer service station and they identified that the crank pulley system had a failure and the vibration damper needed to be replaced. Apparently, this issue also resulted in the engine not properly charging the car battery, which also resulted in battery failure. This car only has about 38,000 miles on it and has been plagued by safety issues. The difficulty steering the car could have resulted in an accident on the road. This same car also had a water pump failure at approximately 35-36k miles that was separately reported to NHTSA previously.

BMW 2021 X5 Engine starter failed. BMW South Miami dealership troubleshooting found the starter motor faulty and replaced it. This failure is NOT part of the current starter recall for BMW X5. (25V644000) My X5 maufactured date is June of 2021. I purchased the X5 In July of 2021. I paid $2166.35 for repairs and I am seaking a refund.
