Example complaints

“Rusted out/ corroded brake lines burst while stopping for a deer running out on the road. Was warned of this problem upon purchase of the vehicle in 2010 and personally coated all brake lines b4 winter every year...never saw worse lines! I own classic cars that are twice as old with shiney original brake lines. The fuel lines also rotted out spilling fuel over the top of the fuel tank and on the ground while filling up. All fuel lines and fuel pump connections were severely rotted. Worst I have seen. Dash consistently changes languages rendering odometer non functional. …”
NHTSA complaint #10818811, filed 2016-01, 120,000 miles“I was leaving my driveway and completely lost all brakes and could not stop. I had to slam on the parking brake to stop. A brake line blew. All the brake lines and fuel lines are completely rotted.this vehicle isn't even 10 years old yet. The fuel line and brake lines are a major safety issue. This truck is a 2500 and I use it for towing trailers if that brake line went while towing it would have been a major accident. The entire underneath of this truck is so rusted the frame brake line and fuel lines are terrible. Someone is going to get killed from GM's cheap steel.”
