We have had issues with this car since it was bought new. All issues have been looked at by the dealer during the factory warranty and still remain unresolved. I have written a letter to Ford headquarters but they sent a complete rejection letter. I was told today by a Ford customer service representative to file a complaint here. I can supply documents and the original letter to Ford if needed. The main issues from purchasing new and driving off the lot are (in rough order of importance): -major paint and clear coat issues (brought to dealer two days after purchase to complain. They have never resolved problem and it has continued to get worse to this day. ) -driver door window stops working intermittently. -car engine surging making car lurch forward (my wife was involved in a minor accident because of this. It was reported to insurance. ) -engine acts like it wants to stall when turning steering wheel in reverse. -headlight lenses completely clouded early on (have had to have restoration done to headlights several times. ) -engine sounds like diesel when ambient temperature is high. -bulge in seal above windshield frame where convertible top seats against it. -stereo interference (loud continuous buzzing sound. ) -ac thump (high pressure coolant line hits firewall when compressor starts. ) -driver door rattle (after the window was worked on but was not fixed. ) -light burned out in ac panel (occurred after stereo was replace to try to eliminate interference, but was not resolved. ) we have maintained and kept our low mileage Mustang in excellent condition otherwise. We don't know where to go from here. Thank you.
