“I have a 2005 Mustang Gt that when temperature drops below 50 my speedometer will stay at different speeds when I am at 0. Sometimes 40 70 when I am stopped. When you turn off key restart car it will usually drop gauge 5 to 10 MPH. I have been reading online of numerous gauge failures on this year model. Sometimes my gas gauge will not work properly.”

“My speedometer and tachometer stopped working around 45000 miles. I took this to the Ford dealership as there is numerous complaints online about this problem expecting this to be fixed. They said it was uncommon and I was out of warranty and would have to pay for this. This should be a recall by Ford for repair.”

“I have replaced 2 batteries on my 2005 mustang. Dealer says there is always a small draw on battery even if nothing is plugged in. They have checked the alternator and it's ok. If I don't drive my car at least 2-3 times a week my battery always dies. The other day I shut my car off for about 20 minutes and it didn't want to start.”

“The instrument cluster on my '05 gt stopped working. It will sometimes show that I am driving at 120 MPH when I am in first gear and in my driveway. Other times it goes 25 MPH on the freeway in fifth gear. This is a serious safety issue as you never know how fast you are driving.”

NHTSA complaint #10473036, filed 2012-08, 29,000 miles

“I am having problems with my speedometer. The needle on the speedometer often gets stuck at a certain speed and will not move when I accelerate. It also starts at 60 and 80 MPH as if it were 0. When this happens the needle goes the max distance as if I were driving 100+ MPH.”
