Example complaints

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

“My rear subframe is rotted out but won't be replaced under warranty because there are no rust holes in the metal. The rust is very extensive, and the car isn't safe to drive. The rear metal brake lines are also rotten and need to be replaced. I've owned many cars older than this one with more miles, and I've never had rusted-out brake lines. This is a safety issue.”

NHTSA complaint #11607686, filed 2024-08

“I brought my car in to my local mechanic and was told my rear suspension was corroded. He said it would cost around five thousand dollars to repair. I researched online and found mercedes did not have a recall but has extended the warranty and will cover the repair to the rear suspension. The mercedes dealer called me and told me my brake lines were rusted out and needed replacement and that it was not covered by the extended warranty and would cost thirty five hundred dollars. …”
