I'm having a recurring nightmare with my charging system, and after replacing two alternators and two batteries, I'm just about as happy as Dick Cheney. I suspect it may be related to the overall electrical problems that have plagued this car (2005 Mustang GT) from jump street, many of which also marred my driving experience in my previous two Mustangs (2000 and 2002).

Why, you might ask, do I continue to buy the same problem? Short answer, other than masochistic tendencies, is that I still love the 'Stang bang for the buck, and they actually declared my 2000 a lemon because of these electrical issues and replaced it with that 2002. But since all three models suffer from this issue, which in one case nearly caused what could have easily been a fatal accident, isn't it time for a recall and some kind of customer compensation?

Whatever is wrong with this dingbat electrical system, it means everything from my dashboard gauges to ragtop and window operation work intermittently, if at all, and this can mean not being able to close up and lock the car, which is highly problematic, especially in high crime areas. Sometimes the windows just open and close themselves. Nice to know, after giving my car a name, that it's alive. But maybe I should've named it "Christine?"

Have never had a Ford. won't have another one. Had Toyota, Honda, Dodge cars, all reach 200,000+ miles, never had an alternator failed. Add that to the $900 to removed 8 spark plugs for the 100,000 mile checkup, and you got yourself a poorly designed car.

Mustang 4.0L

  • Automatic transmission
  • 92,000 miles

So, alternator acts up ...limp car into Courtesy Ford, they say it was battery(which i just replaced). I had too argue with them to check the system and they blew up my battery. This repair cost over four hundred dollars, 2 days before a surgery, and I had no vehicle while recovering from surgery and had too rely on family and friends for follow-up appt rides and groceries.....REALLY.

Mustang Convertible 4.0L V6

  • Automatic transmission
  • 108,000 miles

Batteries weren't lasting as long as they should have since I bought the car with 18K miles so the original alternator was probably not working 100%. Battery light came on at 108K. Replaced alternator and now have 14 volts showing while car is running.

Mustang Conv 4.0L V6

  • Automatic transmission
  • 30,000 miles

Ok, driving down the road, everythings going fine. Oh wait! The radio turned off! Oh, the lights and all turned off! Windows wouldn't roll down either, electric locks could barely work. Stranded on the side of the road, had to have the car towed and then pay the dealership to fix it! It was under warranty, but wasn't covered! It's been another 30k miles and I guess this new alternator is going to die soon also...
