What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2020 BMW X6, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
This issue of the Starter not functioning properly was identified by the manufacturer and brought to my attention through their correspondence. Later confirmed on the NHSTA website. To date, no fix has been made available.
The contact owns a 2020 BMW X6. The contact stated that while the vehicle was parked and attempting to start the vehicle, the vehicle failed to start. The vehicle was towed to an independent mechanic, where it was diagnosed with battery failure. The contact was informed that the battery needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The contact stated that while driving at an undisclosed speed, the engine seized. The contact stated that while attempting to start the vehicle, the vehicle failed to start. In addition, the engine overheating warning light was illuminated. The contact stated that the failure had occurred while the contact was driving on a busy interstate. The contact stated that the failure could have caused a crash. In addition, the contact stated that the situation was very dangerous and scary. The vehicle was towed to the dealer, and the contact was informed that the failure was the result of over attempting to start the vehicle, which might have damaged the battery. In addition, the contact was informed that the battery might need to be replaced. The contact stated that neither the dealer nor the independent mechanic had mentioned the unrepaired recall. The contact later received a recall notification for NHTSA Campaign Number: 25V644000 (Electrical System); however, parts were not yet available. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 67,786.

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
I’ve been having issues with the front end since I purchased the vehicle. The dealership had not diagnosed this issue yet in 3 years. It had caused my vehicle to be in the shop continuously, my front driver side tire is worn out. I had to replace all brakes and rotors after 2 years, numerous sensor issues, radiator loses fluid as well as software issues.
On July 27, 2024, the parking brake on this car would not disengage, thus, I was unable to drive my car. We had to turn off the car for 15 minutes and then step on the gas and brake at the same time at which point the park brake "disengaged." I believe this is a safety/manufacturer issue that needs to be addressed and should be under a broader warranty protection (like 100,000 miles or more).

Seat belts
Reports naming seat belts, buckles, retractors and pretensioners.
From owner reports, verbatim
On December 28, 2023, the "Fasten Seat Belt" sign (rear passenger side seat) and sensor in my BMW x6 starting buzzing even though no one is seating on that seat. I subsequently brought my car to the dealership and the service consultant did an ocular inspection of my seat belt and looked inside the buckle with a flashlight because the seat belt will not lock in place. I was subsequently told that the metal that is supposed to hold the seat belt in the buckle is missing or stuck. Because at that time my car has 59,000 miles, I was told that the warranty has now expired (50,000) and that I have to pay for the diagnoses and fixing of the car seat. Now, the "Fasten Seat belt: sensor for the rear middle seat is also lighted and making the "buzzing sound" even though no one is seating in the middle seat. I believe that my seat belts have become defective and given that I purchased my car around May 10, 2020 - I should not have to pay for fixing seat belt problems for a new car given the safety need for these belts. I would like NTSB to compel BMW to fix my seatbelts.

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.
