In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.

Intermittently when lifting foot off the brake pedal and commence to depress the brake pedal again it causes a lack of braking. Vehicle had been to the dealer, who informed the consumer that they could not locate a problem. *ak

I have a 1994 mercedes benz e320 wagon and the engine wiring harness insulation is completely failing. This resulted in me having to replace it for $1100.

While driving, heard a rattling sound from the front end of the car. Short while later, started to proceed from a stop and the front passenger side suspension coil spring came off the car and exited out the wheel well with a big bang and rolled down the street about 75 feet.
How to read this page
Every figure comes from the National Highway Traffic Safety Administration's public complaint database, which holds every safety-related defect complaint filed by owners since 1995. We refresh it monthly and count each complaint once per component it names. Data through September 6, 2026.
NHTSA only accepts safety-related complaints. Rattles, paint, infotainment bugs and other annoyances are under-reported here, so this page is a map of what fails in ways owners consider dangerous, not a full reliability score.
Counts are raw. Use the year-over-year shape and the component mix, not the absolute numbers. Where a component maps to parts we stock, the row links to that category filtered to the year you are viewing. Air bag and seat belt complaints link to the recall checker instead, because those repairs are almost always covered.
