What owners report
While driving on the highway, my vehicle unexpectedly caught fire due to no fault of my own. Upon investigation, it appears the fire originated from a short in the rear window defroster wiring, which led to significant damage in the right rear C-pillar area…
I smelt and saw smoke coming from the back of my vehicle. I pulled over on to the left side of [XXX] bound. Then, I jumped out of the car to check the truck. I didn't see anything, then i popped the hood and still did not see anything visible.
Car just shut off when driving at 65mph and never started back up, took it in and repair was a bad fuel pump and fuel rail line causing metal shards to go through fuel tank and injectors.
Was simply driving my vehicle to work. It started overheating parked it right away before it got worse as the car alerted had it towed to a shop.
My 330i 2018 bmw has a cracked in the oil housing unit. This is due to bmw putting plastic parts instead of aluminum. After researching this I found thousand of people complaining about the sane thing.
