After 2 weeks in the dealers service group they have decided to replace the rear evap coil and a number of valves…..I guess their approach is to keep replacing parts until the problem goes away. Unfortunately their timeline for obtaining the replacement parts is unknown……they report 45 days or longer. The dealer does not have a comparable loaner to offer, so my daughter’s family of 7 will be forced to cancel their summer vacation plans. Texas lemon law states if the consumer is without a comparable loaner for a period of 30 days total in first 2 years of ownership, then the vehicle is classified as a lemon. In 6 months of ownership this vehicle has spent 1 month and counting in the dealer’s shop. Apparently GM and the dealer aren’t bothered by any of this……lemon law in Texas only requires the dealer to refund the purchase price minus a fee for use of the vehicle before returned. Since market for these vehicles is still good the dealer can just turn around and sell it again. No accountability or consequences to dealer or GM.
