Received called an hour later saying they found problem and that it would cost $1,000 to fix. Far too much money! When I picked up car, there was diagnosis fee of $125!! Doug (svc rep) never advised me there would be a diagnosis charge, which he most certainly did not. Doug flat-out lied saying he did advise me of the fee. Then he took a rude tone and said whether or not he mentioned, the charge was valid and due! With as much money in repairs I have paid to Courtesy and GM due to the poor quality of that piece-of-crap car, Courtesy was going to charge me $125??? No way! Asked for manager, and he waived the charge. Found a repair shop with stellar reviews on Yelp. They gladly diagnosed the car (with no fee, even if no repairs were made with them). And the cost? Only $396. Courtesy Chevrolet has permanently lost my business!"^^ .
