2003 Ford Mustang Owner Comments

problem #5

Mustang 6-cyl

  • 100 miles


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

I was driving on the freeway at 65 mph. All of a sudden the car just stopped running. All dash board lights came on including check engine and theft light was blinking. Luckily traffic was light during the time I was driving. I ended up getting pushed off the freeway by the chp. I had to tow the car to the dealer, and the service advisor stated to me, that a wiring harness that was mounted above the cat converter, and the wire shorted out. Whatever was holding the wire in place must have came off, and that over time the wire shorted out because the wire harness was resting on the very hot surface of the cat converter. The dealer took pictures, and I could not believe that they put such a vital wire harness directly above something that gets extremely hot. I was lucky, but someone else my not be so lucky. No warning lights and a car just shuts completely down while driving. I hope you will look into this issue and not just the year and model of my car. This must be recalled before someone gets hurt or killed.
