Example complaints

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

“Noticed brake fluid on floor of my garage. Found that the brake line to the rear brakes was rusted and leaking. Gm dealer said it was out of warranty so I paid a local garage to install new brake line. It has failed again, 98,000, while I was driving. Lost braking ability. I find that GM will sell me a set of brake lines for $500 and I can have them installed anywhere I want to. Considering the current GM situation with the ignition switch I think they should be made to recall all effected vehicles and fix their rusting brake lines.”

Fuel lines had to be replaced because they completed rusted through and gasoline was leaking out all over. …”
