While driving, the vehicle displayed a 'Drivetrain malfunction' warning on the dashboard and began jerking. I safely pulled over and turned off the vehicle. Immediately after stopping, there was a distinct, strong electrical burning smell coming from the engine compartment. The vehicle was inspected by an authorized BMW dealership. The dealer diagnosed a catastrophic failure of the starter motor. The vehicle's computer logged fault codes 21611A (excessive counter-torque), 21A511 (Start system: Timeout), and 216119 (Line disconnection). These codes confirm the starter motor suffered a severe electrical overload and thermal event. This premature failure and fire hazard identically matches the safety risks outlined in BMW's recent massive starter motor recalls (such as NHTSA Recalls 25V-636 and 26V-056), but my specific vehicle is currently excluded from those recall campaigns. The starter requires complete replacement due to this overheating damage

I am writing to formally express my concern regarding serious and repeated safety-related failures with my 2022 BMW X5 xDrive45e, VIN [XXX] . I purchased this vehicle in 2022 through a custom build, at a purchase price exceeding $80,000, with the expectation of reliability, safety, and premium quality consistent with the BMW brand. In October 2025, while my wife was driving with my son in the vehicle, the hybrid component safety box failed without warning, causing the vehicle to stall on the roadway. This created a dangerous situation for my family. The vehicle was towed to the dealership, repaired, and returned to me on November 4, 2025. Unfortunately, on February 3, 2026, a second serious incident occurred. After my wife picked up my son from school, the vehicle began jerking violently while driving, and a strong sulphur-like odor entered the cabin. Fearing for their safety, she immediately stopped driving. The vehicle was again towed to BMW of Jackson. I was informed today by the service advisor that the failure is due to another hybrid-related component, specifically the EME Hybrid Inverter, and that BMW North America is declining to cover this repair under warranty. These repeated hybrid system failures are deeply concerning, particularly given that both incidents involved my wife and children and posed clear safety risks. As a result, both of my children are now fearful of riding in the vehicle, and this situation has caused significant emotional distress to my family. Given the nature of these failures, the vehicle’s purchase price, and BMW’s emphasis on safety and engineering excellence, I find it unacceptable that a critical hybrid component failure would not be covered under warranty—especially following a prior hybrid system failure less than four months earlier. I am requesting that BMW North America review this matter promptly and provide a reasonable resolution, including warranty coverage for the EME Hybrid Inverter repair.

Like numerous other BMW owners, my transfer case is failing in my vehicle. It’s actively causing jerking/shuddering/locking up at low speeds and while making turns. This poses a significant danger to the driver and passengers in the vehicle, and other drivers as well while turning or trying to merge with traffic. I’ve brought the car into the dealer had the transfer case fluid changed according to the service bulletin that exists for this problem but it persists. I’ve brought the vehicle back into the dealer and told that now BMW suggests paying for another fluid change. This is obviously a known problem (thus the service bulletin), it’s persisted with models like mine for over 5 years, had cost numerous owners significant amounts of monies out of pocket, and poses a safety risk given the transfer case is a foundational component of these vehicles’ drive trains. Finally it’s a problem BMW openly admits they caused with improper fluid in the component. I believe the above meets all criteria for a formal recall that BMW should cover (or reimburse) the costs for given their negligence and the risks it poses. Can you confirm why this hasn’t risen to a formal recall? And confirm the steps you’re actively taking to elevate this to that status with BMW?

Sudden loss of power. Vehicle warning after starting stating power supply issue even after a brand new battery from the dealership. 3 similar incidents in a month. During the final incident the vehicle was again towed to the dealership where it’s been there for over a week and power supply issues persist. They are changing the whole high voltage box due to some unfixable errors.

The malfunction is my water pump is cracked & leaking coolant at 40k miles. The get up performance speed is lagging and delayed especially driving using Eco mode. The safety is at risk as the car is overheating, slow to accelerate and drive comfortably or safely. BMW of Riverside, CA has had to top off my coolant levels twice in a month or so. Bavarian Auto House located at 1009 E Balsam Ave, Anaheim, CA 92805 inspected my vehicle during a brake fluid flush and noticed my cracked leaking water pump. The low coolant levels pop up alert first appeared on my vehicle a month ago in the end of January 2025.

On Dec 9, 2024 I was driving my 2022 BMW X5 45E on (in EV mode) local roads at approximately 30-35mph when all of a sudden I lost power and the steering wheel became tight. My instrument panels all showed a multitude of errors including: "Chassis stabilization", "Power Supply", "Reduced Power", "Transmssion Malfuction", and others I do not recall. I was fortunately able to turn into a parking lot slowly, but the steering was tight to the point I had to use 2 hands to make turn. There was also no throttle response. As soon as the car came to a stop, I powered it off and turned it on. The car's screens were blinking and the car would not turn on. I contacted BMW Roadside and the car was towed to the dealership at East Bay BMW in Pleasanton. As of today I am still waiting for a reply on the condition of the vehicle. Yesterday I was told that they will change out the battery first and see if this solves the problem. My biggest concern is that had this happened to me on the highway that I or someone would have gotten seriously injured or may result in death from an accident. I lost power to the car and the steering became stiff.
