Owner report 11534711 · 2023-07-27 (July 27, 2023)
Fuel tank started leaking gasoline on the driver's side of the car. I only noticed because of the strong smell of gasoline and slipping a puddle of gas. I feel that my safety was at risk if I was to drive around with gasoline leaking out of the car that could have caused an explosion. I took the car to the dealership and the dealership will not cover the repair even though there is an emission warranty on the older versions of this car that have the same fuel tank issue. There was no warning light.

Owner report 11759039 · 2026-08-24 (August 24, 2026)
While driving, suddenly, with no warning smoke came from under the hood. I got off the road and turned off car immediately. Luckily, since I did turn off the car so quickly, it did not burst into flames but did create a fire within the engine. I have video of fire damage and BMW quote on repair stating fire damage. As in the past with BMW, there is a documented history of PCV-heater fires. NHTSA Recall 22V-119 states the BMW PCV valve heaters can short circuit, overheat and cause a fire.
