Example complaints

“Engine seized 10 miles after oil filter housing gasket was replaced. Car has 107k miles and has been meticulously maintained. Now I'm going to have to spend from $8k-$10k for a new engine. Never received a warning light. From what I've been reading, this is not uncommon after that specific job is done and the gasket starts leaking around 100k so it is necessary to address.”
NHTSA complaint #11162866, filed 2018-12, 107,000 miles“For 8 mos now, my car has been stalling. I have taken it in twice and they have not been able to replicate the problem. It happened again yesterday and I called but now it is not under warranty! It happens about 15-20 minutes into my morning commute, stop and go traffic on highway or expressway. Usually at a complete stop or rolling to a stop. It always starts right back up.”
NHTSA complaint #10782912, filed 2015-10, 46,200 miles“Well maintained vehicle with approximately 81,000 miles when the rod bearing broke. Bmw has a record of rod bearing failures and recalls. Bmw is not helping in my case and from my research there has been rod bearing failures in the same year and model as mine. I was driving when I heard knocking in the engine. I pulled over, had to be towed ajd Bmw said the rod bearing went. They said it just went. Plenty of oil in the engine so it wasn't that. I was going about 60 MPH when all of this happened”
NHTSA complaint #11387757, filed 2021-01, 81,000 miles“I was driving in a parking lot at about 5mph, and the vehicle suddenly stopped on its own while I was still pressing the accelerator. I continued to press the accelerator, but the vehicle would not move. After 3 or 4 minutes of trying to determine what the issue was, I put the car in park and restarted the engine. The car was able to accelerate once I turned the car off and restarted. If this would have happened while in traffic, it would have put many people at risk. …”
