Forgot to install C clip on temp sensor on radiator hose which popped out causing major engine damage and blown head gasket which was denied for many months. In Oct. 08 they forgot to tighten bracket which caused wires to smoke and fire.Aug 08-trimmed serpentine belt rather than replaced and car stopped running in middle of interstate. Sept 09 replaced oil pan but forgot to put plug back Oct 08 oil residue on damper they threw out and did not replace. They forgot to put bolts back on sub frame and miracle I was not killed. This caused axle problems. When they replaced bolts they did not have bushings in stock and they released car without these bushings which is a safety violation. When bushings came in they refused to work on our vehicle and we had to go to different mechanic. They told us we needed timing belt when the headgasket was blown. Now there is new recall for coil packs and they refuse to work on our car. The new GM is listening to the service mgr. Who is not telling the complete story nor is the new GM reviewing the facts. Our lives are in danger with this vehicle and since we still owe $15K we cannot trade it in. Started June 2008 and continues until today. Coil packs which were just recalled are causing car not to run and we are stuck

I bought a 2003 Audi A4 convertible in November 2008 and since then the defective convertible top has resulted in the rear glass window to be nearly completely loose. This is a major hazard and represents a danger since the window could fall out and hurt other people. Audi of santa monica said they can't/won't fix it and referred me to an upholstery shop who said they have seen this problem before and can't fix it (despite Audi recommending them for fixing this). A detailed check of numerous online discussion boards (in the U.S. and germany) shows that this is an extremely coming problem for 2003 Audi convertibles that Audi simply refuses to acknowledge. 2003 was the first year that karmann manufacture the roof and, interestingly, harmann in germany seems to accept some responsibility and has fixed this problem for some people, charging only for labor. I strongly recommend that NHTSA look into this faulty manufacturing issue and force Audi to accept responsibility for it.
