Example complaints

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

“I went out to my truck in the morning and my dash board indicator told me to get my brakes checked; everything was fine the night before. I brought the truck into mymechanic and found out that my brake line is corroded and broken. Also found out that this a recurring and consistent problem with the Gmc sierras. I have my truck serviced by an authorized service center on a regular basis and this has never been mentioned to me. This needs to be a recall item! Serious safety threat. Cannot imagine what could have happened if this occurred 2 days later when I was pulling our 40 foot rv. …”
