Living near a salt mine ohio uses salt like crazy I'm fortunate that I do all the work myself rotten brake lines fuel lines that's what happens in the snow belt rot my jimmy is mechanically sound with 190000 miles drive it almost 200 miles a day to and from work unfortunately it will rot to pieces before it dies and I don't think I should have to accept this need to find other ways to get ride of ice on roads in ohio or different alloys to make lines with. A lot of mechanics in the south won't or don't know how to work on corroded parts or some even charge a higher rate.
I replaced my front pads and rotors. Been fine for a week till yesterday I stopped at a light brakes felt slightly spongy, not long after maybe ten minutes three cars ahead of me had stopped as I hit the brake my foot went straight to the floor and I smacked the vehicle in front of me doing appx. 35-40 MPH. It was a four car pileup I took heavy front end damage more or less totaled the vehicle but the airbags had failed to deploy causing me to hit my head on the steering wheel and suffering a concussion. The seatbelt didn't lock as it should have either therefore causing my whiplash to be severe.
The rear brake line keeps giving out even after replacing it and, there is loss of the rear brakes. There has to be some kind of fix that a gmc dealer can provide to resolve this issue.
Ever since I got my jimmy my driver side door will not stay closed unless I slam it. Now the inside panel is tore off due to the slamming. Everyone I meet after this has the same issue but gmc refuse to recll this problem!!!
