Example complaints

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

“Headlight wiring jackets flaked off. Had the ballast and bulb replaced in passenger side headlight, because the headlight no longer worked. Noticed that the wiring was bare & looked like someone had clipped 2 of the wires. After replacing both the ballast & headlight it still did not work. But a couple of days after, turned on the headlights and now it works again. I know this is not safe, I see where others have had the same issue. Not sure how to get the new wiring for the headlight or does the whole thing need replaced? It should be a recall with this many cars having the same issue.”

“The car (2004 330i zhp) often shudders at start up with an erratic idle and continues to do so even when warm. There are no computer fault codes and no check engine light. It feels as if it is ready to stall at any given time with severe idle fluctuations of 100-200 RPM's during stops. Problem is widespread across dozens of zhp (performance package) owners as well as many 2003 and 2004 3 series car owners, particularly those with manual transmissions.”
