What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
On june 21, 2020, on a city street. My white bmw was traveling westward and a black bmw was traveling southbound. The black bmw ran its red light to my green light.
On 8/31/2026 this 2020 BMW X4 was serviced at an authorized dealer ([dealer]) to execute the remedy for official NHTSA Safety Recall Campaign 25V-636 (Engine Starter Relay Fire Risk).
The vehicle recently began making a noticeable noise while turning. I reported this to an authorized BMW dealer before/during service and requested review for possible front-end, steering, suspension, axle, swivel bearing, tie rod, thrust rod, or vehicle-control safety issues.
Water entered through the roof shark fin antenna, leading to corrosion /severe water damage to the Telematics Communication Box Module. -Failure of BMW Emergency SOS Call System, GPS, and Microphone/ Voice for hands-free access.
The contact received notification of NHTSA Campaign Number: 25V636000 (Electrical System). The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was not notified of the issue. The contact had not experienced a failure.
This defect presents a serious safety risk, as failed or leaking tension joints can lead to: Loss of steering control Poor braking stability Increased risk of crash Despite the known nature of this problem, BMW has not issued a recall or provided coverage, placing the financial burden and safety risk on consumers.
There were no warning lights or leaks prior to the vehicle malfunctioning. I ubered to get coolant and once filling the reservoir the coolant immediately leaked out resulting in me needing a tow to the dealership.
No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the driver's side seat belt. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 20V164000 (Seat Belt, Air Bags) but the VIN was not included.
