Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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.”
