Example complaints

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

“Unknown battery drain causes premature failure of battery and more than average replacement intervals - every two years as opposed to 5-7 yrs. Car will not start if idle for 24-48 hours. I would like to file a claim for the charging system and associated equipment for any Bmw M5 (e39) built between 2000-2003.”
