“On 8/31/2026 this 2020 BMW X4 was serviced at an authorized dealer (BMW of Tyler) to execute the remedy for official NHTSA Safety Recall Campaign 25V-636 (Engine Starter Relay Fire Risk). INCIDENT DESCRIPTION: Within minutes of picking up the vehicle post-repair and entering an active roadway, the vehicle suffered an immediate, un-warned, total loss of all electrical power. The engine stalled, all digital dashboard instrumentation went black, and power steering/braking assistance were compromised. The vehicle came to a complete stop in moving traffic. The total power failure prevented the activation of hazard lights, rendering the blacked-out vehicle invisible to surrounding traffic and nearly causing a high-speed rear-end collision. The vehicle was towed back to the dealer center. TECHNICAL BASIS FOR DEFECT/WORKMANSHIP FAILURE: Campaign 25V-636 requires replacing or manipulating vulnerable electrical relay and starter assembly points tied directly to the main 12V electrical infrastructure and power distribution system.

“I am filing a safety complaint for my 2020 BMW X4, VIN [XXX]. 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.

I was quoted approx. $1,950 for thrust rods and approx. $3,450 for motor mounts. I am concerned the worn thrust rod bushings involve the same general front suspension/steering/vehicle-handling system as the turning-noise concern I reported. I asked BMW North America and the dealer to review whether this condition may relate to or overlap with known BMW X4 steering/front axle/suspension recalls, including NHTSA Recall Nos. 19V678000, 19V738000, and 20V355000. BMW/dealer representatives stated there are no open recalls for my VIN and that BMW NA will not provide assistance, but I have not received a complete written explanation confirming that the dealer’s actual findings were reviewed against those…”
