The front driveshaft universal joint failed causing the drive shaft to bust a hole in the engine and crack the transmission. There was no knocking noise prior to failure. It suddenly failed, disengaged and caused damage. I was told by service manager the u-bolt must have been defective to have failed without warning.
I am having issues with the starter motor / battery. I have read extensively about issues with BMW X5 models having recalls during the production period of my vehicle. BMW is trying to charge $3,000 for a new starter and battery. I feel that this is a known and significant issue with BMW X5 vehicles produced during the same period as my vehicle and would like for this to be covered under recall.
After the car was.parked in sun for aome time during shopping at Costco, it did not start. We had to use remote starter which worked. However, upon doing some research I found that overheated starter is a known and recalled problem with 2021 X5 and remote start could have caused fire. Dealership also confirmed it to be the smae pronlem , but BMW has not listed this vin as recalled. I contacted BMW and they denied that it was same.problem, although mine is also 2021 X5 with smae.overheated starter problem.
2021 BMW X5 xDrive45e PHEV, built October 2020 by BMW AG (Germany). In-service Oct 28, 2021. Vehicle intermittently shows "Drivetrain Malfunction — you can continue driving" warning. DME scan reveals 5 fault codes, all for the conventional 12V pinion starter: 21A50A — Pinion starter: timeout occurred several times in succession 21A511 — Pinion starter: timeout 21611A — Pinion starter: starting torque could not be built up; high counter torque and/or undervoltage 216119 — Pinion starter: line break in starter control (KL50/KL30) 216115 — Pinion starter: attempt to start with blocked starter detected 21A50A and 216115 are protected memory codes that cannot be cleared by standard OBD-II tools. The main 12V AGM battery was replaced and registered; codes continue to recur. This signature matches the B58 pinion starter defect addressed in NHTSA Recall 24V-576 (Aug 2024) and 25V644 (Nov 2025, physical starter replacement). The vehicle's German manufacture date falls inside the production windows of KBA recalls 15630R, 15632R, and 15633R — all covering X5 G05 for short-circuit and fire risk from starter relay corrosion or inadequate mounting. BMW AG has issued an ADAC advisory not to leave affected vehicles running unattended after starting. BMW NA Customer Relations was contacted. Initial verbal response: U.S. recalls don't apply because the xDrive45e PHEV uses a different starter than non-hybrid B58 vehicles. However, codes 216115 and 216119 only exist on vehicles equipped with a conventional pinion starter — confirming this vehicle has the same component. The subsequent written denial pivoted to warranty expiration without addressing the technical or recall-scope questions. Filing so the field record reflects this defect signature for future U.S. recall scope expansion analysis.
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 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.
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.
The vehicle shakes at low speeds with a jolt and vibration when turning. When I pressed the accelerator from a standstill, the gas pedal broke off from its floor mounted bracket.

The contact stated that while driving at an undisclosed speed, the coolant warning light illuminated with the message "Coolant Dangerously Low - Fill Right Away" displayed on the instrument panel. The message was displayed on several occasions. The vehicle was taken to a dealer where the dealer discovered coolant leaking from the bottom of the vehicle and diagnosed that the water pump needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure and informed the contact that the vehicle was no longer under warranty. The failure mileage was approximately 40,000. The VIN was not available.
Component Failed: Water pump (engine cooling system) - Part has been superseded by BMW with upgraded version, indicating manufacturer awareness of defect. Failed component retained and available for inspection upon request. Safety Risk: Complete water pump failure at 56,611 miles created immediate risk of catastrophic engine overheating and potential engine seizure while driving. BMW-certified mechanic warned that driving vehicle even short distances could result in total engine failure, creating risk of: Sudden loss of power on highways/intersections Engine fire from overheating Being stranded in dangerous locations/conditions Complete loss of steering assist if engine stops Confirmation: BMW-certified independent mechanic (formerly employed by BMW) confirmed water pump failure and identified it as "common B58 engine issue." BMW dealer (Silver Spring) immediately quoted exact repair cost of $2,300, indicating familiarity with this failure pattern. Mechanic documented that BMW has superseded the original part with an upgraded design, suggesting manufacturer acknowledgment of defect. Inspection Status: Failed part preserved by mechanic with full documentation including BMW's superseded part number from their system. Vehicle not inspected by BMW due to dealer network failure - three dealers failed to respond, one took 5+ hours to return call, none could provide service in reasonable timeframe. Warning Signs: No prior warning symptoms. Failure was sudden and catastrophic. Temperature gauge spiked without warning during normal driving conditions. No previous cooling system issues or warning lights. Regular maintenance performed per BMW specifications. Additional Pattern Evidence: Research reveals extensive documentation of identical B58 engine water pump failures between 40,000-60,000 miles across multiple BMW models (X5, X3, 3-series, 5-series) on owner forums. BMW's decision to supersede the part without issuing a recall suggests they are aware of the defect.
A drivetrain malfunction warning, chassis warning, auto level suspension was locked, and check engine light was on while driving on the freeway. We made it home safely and parked the BMW X5 45e inside the garage. I plugged in my charger and was not able to charge. Went to start on electric mode/hybrid mode but was not able to turn on. Then I switched to sport mode via gas and engine started but stuttered, and was unable to switch gears from parking to reverse or to forward. Engine continued to shut studded and then engine and electrical completely shut down. I will contact BMW Riverside on Monday.
In the middle of a busy intersection, the car just completely shut down. The car only had ~35,000 miles on the odometer and has been serviced only by BMW. It turned out that the water pump broke, which led to downstream impact on additional surrounding systems. BMW X5’s up to model year 2019 had recalls due to faulty water pumps. From an independent search online, it appears there are many owners of 2021 BMWs who have experienced water pump failures like I did. This could have led to a major safety incident as my husband nearly avoided an accident. If this had occurred suddenly on a highway, for example, that could have resulted in a multi-car accident as the car very suddenly died and came to a stop.
The contact owns a 2021 BMW X5. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was not taken to the dealer or an independent mechanic; however, the contact used an OBD scanner, which diagnosed a failure with the water pump. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 24V608000 (Engine and Engine Cooling, Electrical System), but the VIN was not included in the recall. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was 72,500.
Starter problem . When starting the start button , we have to do couple times .i saw recalls for starter problems on ur website and internet too

In a parking garage I found a open space and slowly moving towards that to park, car was approaching space at about 10 ft from that, all of a sudden car accelerated and lurched forward and hit the parking structure wall. Airbags deployed for all three of us, one of my colleagues was in passenger seat, another in the back seat. There was no warning on no time to react, this happens in seconds.
While driving about 60 mph on a freeway, the vehicle rapidly flashed several "advanced driver system failure" messages, lost all power and came to a stop. It was not possible to prevent the vehicle from rapidly decelerating even by depressing the accelerator all the way to the floor. The vehicle rapidly decelerated, forcing other drivers behind to swerve to avoid a crash.
The contact owns a 2021 BMW X5. The contact stated that as her husband was stopped at a stop light, the vehicle began to rev after he had taken his foot off the brake pedal without warning. Once her husband placed his foot back on the brake pedal, the revving stopped, and her husband was able to resume normal driving. On a separate occasion, her husband was waiting for a vehicle to move out of a parking spot; the same failure occurred as her husband took his foot off the brake pedal. Her husband was forced to slam on the brakes as the engine continued to rev and the vehicle lurched forward. The contact who was seated in the passenger’s seat, shut off the vehicle to avoid hitting the vehicle in front. Her husband restarted the vehicle and drove it home; he then had the vehicle towed to the dealer the next day. The dealer inspected the vehicle but could not duplicate the failure. The service tech was not satisfied with the results and decided to call the manufacturer to approve more testing of the vehicle. The vehicle had yet to be repaired and remained in the possession of the dealer. The failure mileage was approximately 14,000. The VIN was not available.
Previously reported that the BMW X5e, Plug in hybrid, shuts itself off once the driver's door is opened leaving anybody in the car at risk of serious health problems or even death! A menu selection option should disable this unsafe practice but it does not work. As if there is a software glitch. Other models, the X3e stays on when the driver's door is opened. I've previously reported this item but now my father has injured himself recently. After a medical appointment and retrieving his medications my father was in the car in unsafe and deadly heat and attempted to exit the vehicle due to the car shutting itself off and he fell and hurt himself. The manufacturer has been contacted several times and at times they say this should not be happening but the dealers are saying that is how the vehicle is designed. I also have videos of the other models not shutting off for review. PLEASE FIX THIS ITEM!
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
