2021 BMW X5 Problems

The drivetrain warning light came on shortly after I started the vehicle. I noticed acceleration issues both while driving on side streets and on the freeway. I took the X5 45e into the repair center the day after the notice came on especially given the experience on the freeway, which happened during rush hour traffic. Upon inspection, I was told the starter was beginning to fail and that while there had been a recall on starters on many other BMW models, it did not include the X5 45e. BMW advised I replace the starter immediately due to safety, which cost $2,600. Two weeks later, the same drivetrain light has come on and the X5 is back at the service center for diagnosis.

Auto Start/Stop button needs to be pressed three times to start the vehicle.

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.

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 reporting a front differential/front drive axle failure and a separate steering wheel/steering column adjustment issue. The vehicle was brought to an independent BMW/German repair shop for a routine oil change/inspection. The shop advised me that the front differential/front drive axle assembly had failed or was severely damaged and needed repair/replacement. The vehicle/component is currently at the shop and should be available for inspection upon request. I am concerned this could put my safety and others at risk because the front differential is part of the AWD drivetrain. If it fails further while driving, it could affect drivability, traction, or vehicle control, especially at speed or in poor road conditions. The issue has been confirmed by an independent service center. To my knowledge, it has not yet been inspected by BMW, police, insurance, or government reps. A third-party warranty inspector may inspect it before repair. The exact cause is UNKNOWN. I was told BMW appears aware of this issue because the replacement part has a newer/superseded part number. This suggests BMW may have revised or updated the original part. I do not know if BMW has formally acknowledged a defect, but I am concerned this may be a broader issue given the low mileage. Separately, the power-adjustable steering wheel/steering column sometimes makes a grinding/vibrating noise when I start the vehicle and the wheel automatically moves out/down into the driving position. There were no warning lamps or dashboard messages. The exact date it first appeared is UNKNOWN, but it has occurred more than once. I previously raised this type of issue with a BMW dealer and was told it was a known issue. The exact cause is UNKNOWN. I am concerned it could involve the steering column adjustment mechanism or related components. I am reporting both issues because the vehicle is low mileage and I am concerned they may be safety-related defects rather than isolated maintenance items.

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.

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 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.

Described by BMW as a "malfunctioning passenger restraint system", the sensor detecting weight in the seats is faulty without any external factors. The safety of both minors and adults is placed at risk when a system like this malfunctions, either keeping the airbag on or off. The automatically-adjusting seatbelt is also affected by this. There was a warning message for this displayed.

Formally reporting a serious and recurring safety issue with my 2021 BMW X5. Over the past five months, I experienced three separate incidents where the vehicle abruptly stopped while driving, each time displaying a red car warning light on the dashboard. The red malfunction symbol was similar to the below image (found online) Description of the Issue: Each of these terrifying safety experiences occurred while the vehicle was in motion—all on surface streets—the car suddenly came to a jarring and immediate stop on its own without my input or applying the brakes. There were no cars close to or in front of me or debris in the road that would require the car to stop to avoid impact. The red car icon appeared on the dashboard (commonly associated with collision warning or automatic emergency braking systems). The abrupt stop caused my seatbelt to constrict, jarring of my neck and ongoing concern that it will happen again. Thankfully, no accident occurred, but the abrupt stops could have easily caused a serious or fatal accident, especially under highway conditions. My Concerns: This represents a serious safety hazard not only to me and my passengers but to other drivers on the road. The issue appears to be a malfunction in the automated safety or integrated systems, possibly involving the forward collision warning or automatic emergency braking systems. My local BMW dealership (Gwinnett Place BMW) has given me an estimate of $480 to perform 2 hours of scans/diagnostics to inspect the vehicle. No loaner car or transportation offered. This is a known issue and documented in online forums and comments. I have lost confidence and trust in my vehicle and feel unsafe. For a $70k automobile that should not be the case. Requested Action: I am requesting BMW investigate this matter urgently, outline next steps at no charge since multiple reports exist of similar incidents, and provide a clear resolution, including any necessary recalls

Good Morning, I was driving down the road at around 60 mph in my car. Abruptly my car had simultaneous warning lights about 12 of them. More importantly, I lost my power steering and brake by wire putting all of our lives at risk. The speedometer , air bags, restraint systems all failed and went out. The car wouldn't turn off on the side of the road and after about 5 minutes I was able to get it off and called BmW assist for a tow. Since it was night and raining I and waiting for a tow truck was dangerous I attempted to restart my car and get successfully got it to the nearest exit. All the warning lights were off. About 15 minutes later on the limp home the same thing happened with all the fault codes so my family decided to Uber home. I took the car to BMW Rockville and they did diagnostics and we're not able to replicate the problem. They returned my car back to me the same day with no repairs. I'm concerned. There was no indication or warning lights before the electrical failure. It was completely out of the blue.

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.

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 vehicle's HVAC system failed due to a leaking air conditioning evaporator core. This single component handles both cabin cooling and the windshield defrost/defog function, so its failure compromises a safety-critical visibility system in addition to climate control. The failed component is available for inspection upon request. Safety risk: The vehicle is operated primarily in Florida, where ambient temperatures regularly exceed 95°F and interior cabin temperatures without functioning AC can exceed 130°F. Operating a vehicle in these conditions causes driver fatigue, reduced reaction time, and heat-related illness — all of which compromise safe vehicle operation. Loss of the defrost/defog function also creates a visibility hazard in the humid and rainy conditions common to the region. Vulnerable passengers including children and elderly riders are at additional risk of heat-related illness. Confirmation: The failure was diagnosed and confirmed by an authorized BMW dealer service department as a leaking evaporator core requiring complete dashboard removal to repair, with a quoted repair cost in the multiple thousands of dollars. Inspection: The vehicle has been inspected by the dealer only. It has not been inspected by the manufacturer, police, or insurance representatives. Warning indicators: No warning lamps or dashboard messages appeared prior to the failure. The first symptom was sudden loss of cabin cooling from the AC system. Critical context: This failure occurred at only 12,500 miles on a five-year-old vehicle that has been driven an average of approximately 2,500 miles per year. AC evaporator cores are not wear items and should not fail under any reasonable use conditions at this mileage. This is a widely documented defect pattern affecting 2019–2026 BMW G-series vehicles (X5, X6, X7, and Alpina XB7). Numerous owners across multiple model years have reported identical premature pinhole evaporator leaks at low mileage. The leading technical analysis attri

I was driving and I heard a huge explosion so I pulled over and found that the panoramic sunroof had exploded.

Unintended acceleration when slowing to a stop. Car accelerated requiring significant brake pressure to avoid hitting the stopped car ahead. This has happened on two separate occasions. Checked to see if carpet or any other physical interference could have caused the issue. No issues found. Cruise control was lot activated and incident was a low speed.

DROVE AT THE SPEED OF 75 MPH IN THE HIGHWAY ALL IN A SUDDEN THE CAR LOST POWER UNTIL ITS SPEED DROPPED TO 62 MPH. IT IS A HYBRID. DASH BOARD SHOWED SOME RESERVED BATTERY POWER AND HALF TANK OF GASOLINE. IT IS A BIG SAFETY ISSUE. NEED TO FIND THE CAUSE OF IT.

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.

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.

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.

The low beam headlights do not illuminate the road sufficiently when there are dips in the road or going up hill. The dealer says the lights are fine but relative to the other cars, there is clearly a problem with low beams on undulating roads. On undulating roads or going up hills, the low beams often only illuminate about 20 ft in front of the car. The problem appears to be BMW has drastically limited the upward lighting from the lights for safety of other drivers. However, they have gone too far and created a safety issue with too little upward illumination to be safe on uneven roads. The low beams are great on a perfectly flat surface, but even with a small up hill grade, the low beams are not set to provide enough lighting of the road. I have taken to driving with high beams on for undulating roads because of the lighting provided by the low beams is so bad. This means inadvertently blinding oncoming drivers because I don't turn the high beam headlights down soon enough. I often need to use high beams to read the names of side street signs. The turn signal does a better job illuminating these side street signs than the low beams. By trying to enhance safety for on coming drivers from low beams, they forgot to account for real world driving condition of undulating roads and have created a worse safety issue by forcing more frequent use of high beams that absolutely blind on coming divers.
