“After changing the battery on my 2006 Ford Mustang Gt with 5 speed manual transmission it idles very rough and sometimes dies during driving or idles so low the power steering is not fully functional resulting in excessive steering effort. The car ran fine until the battery was replaced. I followed the relearn procedure in the owners manual but it did not help.”
NHTSA complaint #10369024, filed 2010-12, 40,000 miles“Happened 2 consecutive days. My wife was driving at around 30-40 miles per hour and all of a sudden it's like the car took off and began accelerating on its own. Breaking would not really slow it down. She was lucky enough to be able to throw the car in neutral ti shiite down but the vehicle kept revving. She had to shut it down and remove the key before it would stop. It's scary when it happens. It happened to me a day earlier at the time I thought it was a fluke. Hopefully too many people don't get killed before the NHTSA takes action. …”
NHTSA complaint #10592673, filed 2014-05, 25,370 miles“My 2006 Mustang Gt has been in the service department three times within 2 months time. When you make a left or right turn there is a grinding sound. They have installed 2 clutch packs (kit-axle dif, 3 gear and pinions, and a new flange. I know it is not the way the vehicle is driven. It was bought new in march 2006 and it only has 7000 miles on it and this is february 2007. The car is not beat at all. If these vehicles are supposed to be high performance vehicles. Could you imagine what would happen if the rear end was to lock up? Am I the only one having this problem? …”
NHTSA complaint #10182275, filed 2007-02, 4,400 miles“Squealing/grinding noise from rear end on low speed turns at 7000 miles. Dealer identified the source as the rear axle and put in a new diff clutch pack. Vehicle was fine for a few months but the same sound has returned, however it is intermittent and quieter. Mileage is now about 14,000. Rear ends should not be wearing out every 10k miles on a high performance vehicle.”
