What owners wrote
Dt: purchased vehicle in november 2003, and on 12-22-03 had a minor accident. This occurred at a low speed at which consumer tapped another vehicle from behind. Took vehicle to a dealer. He checked the vehicle diagnosticians via computer, but the codes checked out as well as a test drive and inspection from the service department. This checked out as adequate, no problems found. About 2 months later, experienced a similar accident. Consumer called GM to inquire about this problem.
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.
