Failure Date: 07/05/2010

2006 Mustang gt manual transmission. Replacement of battery results in engine stalling with air conditioning on when clutch depressed. . The owners manual states on replacing battery the computer needs to relearn idle. This does not work at least not in a reasonable amount of time. The vehicle has been driven over a number of days with no improvement. With the air conditioner running and depressing the clutch either coming to stop or turning a corner the engine idle will drop far enough where the vehicle will stall resulting in a loss of power steering and power brakes possibly creating a dangerous situation. The vehicle ran correctly before the battery replacement and only has 22,000 miles. Googling this issue on the internet finds numerous problems which are identical of which owners of the 4. 6l Ford v8 (not just Mustang) are reporting idle and stalling problems after replacing the battery and with the issue not resolving itself as the owners manual states resulting in either a computer reflash or throttle body replacement. This defect could result in a crash causing serious injury or death. Ford should recall affected vehicles and have the default idle setting set for a higher value so the air conditioner when engaged does not result in the engine stalling. The idle of engine is erratic with the air conditioner on since it is engaging and disengaging due to the low idle speed < 500rpm. By not using the air conditioner the idle speed will return to its normal speed of around 600 to 700rpm but still fluctuates slightly. Not being able to use the air conditioner is not acceptable, especially in the south east. The control feed back of the idle system is incorrectly operating with the air conditioner load on it.

Failure Date: 04/02/2008

The battery in my 2005 Mustang convertible has gone dead twice. There is a technical service bulletin out on this, TSB 07-5-13 which says to tell the owner to buy a battery charger. This TSB applies to 2005-2008 Mustangs, 2005 explorer sport trac, 2005-2008 expeditions and explorers, 2007-2008 explorer sport trac, 2005-2008 Lincoln navigator and the 2005-2008 Mercury mountaineer. Ford knows there is a constant drain on these cars that drains the battery unless the car is driven basically every day. They refuse to even replace the battery.

Failure Date: 12/15/2005

I have a 2000 Ford 3. 8 liter Mustang. It has a vibration and covert Ford says its needs new motor. I bought this car new, took great care of motor, it just turned 70,000 miles. Covert says it has excessive end play on the crankshaft due to wear. I think I have an american-made problem. 70,000 miles???? thanks for any help that you can give me. They want $4,600. 00. I think Ford owes me most of that at the very least because I sure can't afford to fix it. You know its funny also because up to this point that car had never broken down and had never been in the shop . This is other than 15 oil changes two batteries and two sets of tires. . . I just think its not normal. Please help with suggestion.

Failure Date: 05/15/2003

I bought the vehicle used on may 03, 2003 from ramey Ford in tazewell, va and under the terms that they would check the clutch for vibration. Upon checking the clutch, I was advised that the clutch rod needed replaced and this was completed. After getting the vehicle back the first time, I have gone through an ongoing problem with the clutch making a vibration/rattle type noise that comes and goes even after the pressure plate, throw-out bearing, and fly-wheel were replaced. Also, for 3 1/2 to 4 months the service engine soon light would come on periodically and start blinking and then go off, this has finally stopped after 3 attempts at fixing the problem, after the pcm was reprogrammed and a coil pack was changed. For a car that looks brand new inside and out, these constant problems have been very troublesome and aggravating especially after 6 repair attempts (going on 7).
