NHTSA Complaint #11619815 — 2014 BMW X3

I have a 2014 X3 xDrive28i with 114, 000 miles. On August 4th 2024 while I was going 15 miles per hour on a residential road, when my iDrive instrument notification panel displayed "drivetrain malfunction! pullover shut off engine". I immediately came to a stop and turned off the engine, I was unable to re-start it afterwards. I had it towed to my local Ralley BMW dealer, where it then restarted after being removed from the flatbed tow truck. They were unable to determine the cause of the issue. They did a software update and told me that was probably all it was. I soon found out there is a massive issue with the timing chain & chain guides that can cause the timing to skip, resulting in premature shutdown or catastrophic engine failure. I took it to a reputable independent shop who later identified that the timing chain had excessive slack and was not able to be adjusted for proper tension, due to the catastrophic failure of the timing guides. Required repairs will cost upwards of $4,000.00, which I am currently in the process of completing.
