2021 BMW X5

Around September, 2025 several small puddles was under the vehicle. Made an appointment with BMW to have a 2021, X5 inspected. The BMW dealership technicians diagnosed the problem as a Water pump -Engine coolant. There was no previous warning messages notifying a problem with the vehicle cooling system. Vehicle total mileage was around 58,000 miles at the time of problem found.Cost of damage was over $2,000 to fix at dealership.

Steering the vehicle in a low gear causes the vehicle to tremble or shudder. The dealership identified the problem to be the transfer case fluid. In manufacturing, BMW put a fluid which did not meet the specifications of the vehicle. The transfer case fluid is documented in the manual of BMW X5 M50i (2021) to be something which does not require replacement in the lifetime of the vehicle. I raised this issue when the vehicle was under warranty, but the dealership ignored the issue. After the warranty period was over (62,000 miles), the dealer recommended that I replace the fluid to fix the shudder issue. It is a very well known issue, and there is a service bulletin issued to the dealerships to deal with this particular case (SIB 27 02 20). After the fluid replacement, the issue went away. This issue is widely known by the dealership, and it is a safety issue. I had to pay for the fluid replacement, and I believe BMW should have recalled this issue to replace the fluid for ALL X5s manufactured in 2020 and 2021. This is a safety issue.

Component Failed: Water pump (engine cooling system) - Part has been superseded by BMW with upgraded version, indicating manufacturer awareness of defect.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 Mechanic documented that BMW has superseded the original part with an upgraded design, suggesting manufacturer acknowledgment of defect.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.

Started car and 2 error messages popped up, one for powertrain warning and one for battery charging system. contacted dealer and was informed as long as vehicle drives it is ok to bring it in however on the way to the dealer car died and would not start. Dealer mentioned they charged the battery and reset system however could not find any other faults with the car. approximately 1 month has gone by and the exact same warning appeared. Had vehicle towed to a different dealer and they said they will once again be resetting the system to see if that fixes the issue. Car is still under warranty but near expiration

Drivetrain - A drivetrain malfunction message came-up a few weeks back on the high-way indicating “It is safe to drive but with reduced power” and the vehicle suddenly slowed down on the highway with less power to drive putting us in unsafe condition. The vehicle has less than 25,000 miles. The incident was reported to a BMW dealer for reporting to BMW and with a request for investigation and fixing prior to warranty expiration. Unknown - After a long drive (some times after a short drive) when the vehicle (PHEV) is parked and plugged-in, a loud noise can be heard. The noise goes away once its unplugged and locked. The incident was reported to a BMW dealer for reporting to BMW and with a request for investigation and fixing prior to warranty expiration.

The contact owned a 2021 BMW X5. The contact stated that while sitting in the vehicle and with the vehicle running, it suddenly accelerated on its own. As a result, the vehicle jolted into traffic and collided first with a bicyclist before continuing on to collide with the rear of another vehicle. The bicyclist sustained minor injuries. A pedestrian later reported that they were also struck by the vehicle, but the contact stated that she was skeptical of the validity of their claim. The air bags did deploy. A police report was filed, and injuries were reported. The driver and passenger were both treated on scene by EMS and later evaluated at an area hospital for injuries resulting from air bag deployment. The bicyclist and a pedestrian were both treated at an area hospital for unknown injuries. No warning lights were illuminated. The vehicle was towed to a tow yard and declared a total loss. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 36,000.

While driving on highway/turnpike with cruise control on at 70 mph, drivetrain malfunction warning appeared and lost power. After turning off cruise control and playing around with buttons, could only get car to go about 35-40 mph, top speed with peddle to the floor. Very scary situation in traffic on busy highway. This happened twice about a month apart. First time, had to drive about 10+ miles in right lane with blinkers on to get to an exit. It was late at night and I didn't want to stop on my own. Once turned the car off and on a couple of time seemed to clear the error and I was able to drive city roads at minimal speed limit. Next day car was back to normal. Second time, drove about 2 miles to the exit with the blinkers on. This time when I restarted the car there was still not a lot of power. Drove for a bit but wasn't able to make it to speed limit of 45 mph. Made it home and turned car off again, next day it was okay. After restarting car a couple of times problem seems to go away. Took it to the dealer and all they did was "reset the system" which does not seem like anything is fixed. Will wait and see.

Car was parked in fairly level spot with engine off, gear selector in park position, , key fob not near vehicle. Approx 30 minutes later, I returned to find vehicle approx 30 feet behind parking spot, having apparently drifted into another car in parking lot. No idea how car moved. I believe some electronic release of parking selector allowed car to roll.

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.
