2022 BMW X5

The high-voltage battery system (this is a plug-in hybrid) began intermittently displaying a "battery not properly charging" warning approximately 6 months ago; the issue would resolve after plugging in and charging. On July 14, 2026, while driving, the vehicle displayed a "critical battery failure - pull over immediately and drive slowly" warning. The driver pulled over and shut off the vehicle; the warning cleared and the car appeared to drive normally afterward. This warning recurred several times over the following weeks under the same pattern. On August 6, 2026, the same critical battery failure warning appeared while driving; this time steering feel and drivetrain response were abnormal, and the air conditioning and several electronic features stopped working. Our safety, and the safety of other drivers on the road, was put at risk by the sudden loss of full vehicle control while in motion. The vehicle has been at an authorized BMW dealership for inspection since August 7, 2026; a full diagnosis is pending. Dealer service staff independently remarked that two other BMW X-series plug-in hybrids came in that same morning with the identical warning and symptoms, suggesting this may be a widespread component defect rather than an isolated issue.

The electric A/C compressor on my 2022 BMW X5 xDrive45e (VIN [XXX] ) failed internally at approximately 59,000 miles, causing metal debris to circulate throughout the refrigerant system. The failed compressor and contaminated components are at BMW of Sterling (Sterling, VA) and available for inspection. This is a safety concern because the A/C refrigerant circuit provides thermal management for the high-voltage hybrid battery. BMW of Sterling's service advisor confirmed in writing that the A/C system is "a critical component of your vehicle's HV system," that there is no independent backup cooling system, and that the failure "can cause potential high voltage battery failures." Without active cooling, the HV battery is at risk of overheating, which could result in a thermal event. The failure was diagnosed and confirmed by BMW of Sterling. They categorized the repair as "EHV: FULLY ELECTRIC OR HYBRID VEHICLE DRIVETRAIN DIAGNOSTICS" with the complaint "HIGH VOLTAGE SYSTEM ERROR." The repair estimate is $11,356.59 and requires replacement of the compressor, condenser, all expansion valves, and a double system flush. BMW Service Information Bulletin SI B64 09 21 documents this exact failure pattern for the G05 X5 xDrive45e, and BMW created a dedicated repair kit (part 64 50 5 A5B 590) for it. This is my second major HV component failure. A battery cell replacement was performed under warranty in 2025. Both failures were confirmed by the dealership to be component defects unrelated to owner use. Prior to complete failure, a fan noise was present in the front driver's area for a period of time before it stopped, consistent with the compressor degrading before failing entirely. A high voltage system error was displayed. BMW NA (case #XXX) has declined warranty coverage despite the vehicle being within the 8-year/80,000-mile HV battery warranty.

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.
