“Again, I am writing. I implore you to reinvestigation Gmc for rusted brake lines. We replaced ours after they were so rusted, being a camping family, towing a trailer we could have all died. I understand that your office has investigated this and for whatever reason determined it was normal wear and tear but I think that your department is on overload and didn't want to handle another GM recall. Gm and consumers know that the company got away with not issuing a recall. …”

“After a full day of driving with my child in the car I went out on my own to get him medicine. While attempting to stop at the end of my block the brake pedal felt funny. I went to the next stop sign and attempted to stop and my vehicle wouldn't stop. I ended up rolling right into the middle of the intersection. I realized there was a big problem so crawled back to my driveway. I then noticed the whole underside of my vehicle was wet and now my driveway was soaked with brake fluid. One of the steel lines burst. After I looked at them I noticed they are all rusted and in very bad shape. …”
