I purchased 1of 11 General motors vehicles with known documented transmission failures. (2008 Saturn Aura) GM dealer (my oppinon) misdiagnosed the first failure, charging $1, 610.35 for repair. After repair, Vehicle still had similar shifting problems. Immediately called dealer (Williamson Automotive) in Miami, FL. spoke to service advisor (Tony Martinez), he advised driving for a while, (corroborated by service manager, Rolondo, later) if the problem still continued, bring the vehicle back for evaluation. I drove the vehicle for approx 300 miles, experienced "total" transmission failure.. The vehicle was towed back to the dealer. Was told an additional repair cost of $3, 222.00 was needed. General Motors. according to service manager, refused to honor the mileage limit (120, 000) stated in the published service bulletin and pay for repairs, for faulity transmission, because time limit was not met. $4, 832.00 for General motors mistakes..
