“My 2006 Mustang Gt convertible is now on its second Ford battery under warranty for about 3 months now. 36k and while driving home last night the radio shut off and a battery low message displayed on the radio followed by all the yellow caution lights, ABS/traction control off/check engine and am sure I detected a burning wire odor. Alternator at only 36k? The voltage meter was dead as well. I really enjoy the car and am surprised about this.”

“A few weekends ago I purchased a very nice looking 06 Mustang Gt with 87,000 (apx) miles. Car had just been cleaned up very nicely and looked like a good deal. On the way home I took it through the car wash and came to discover why it had been so cleaned out. Water began pouring in under the passenger side glove compartment. Like a water fall. The water didn't stop until there was a good 4 inches on the floor. What a nightmare. The water smelled terrible. I smell a awful mold/mildew smell now that won't go away. There were small electrical issues at the time that seem to have cleared up... …”

“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. …”

“Lost function of brake lights, turn signals and flashers. Ford dealer in winston salem, nc said the drain below the windshield has stopped up and diverted the water via the wiring to the sjb thereby shorting it out. Had new sjb installed and water removed from passenger floor area. Took 2 days for carpeting to dry out. Cost was 610.38 plus the sjb. This situation could have caused an accident for not having brake lights or turn signals. It is now july 1, 2014 and the same part has failed again but without the water issue. The car is going back in the shop tomorrow. …”

“1. Prior unrelated discussion with a tow truck driver advised me that he has had to tow in a couple of cars that are the same make and model as mine. He advised me that the positive battery cable were failing. He advised me to check it. 2. I checked my positive battery cable connection to the battery yesterday. There was severe corrosion and 1/2 of the connecting clamp was eaten away by corrosion at the positive side of the battery/cable. 3. I cleaned the connection as best I could but I will be calling Ford as vehicle is only 1 year old. Cable needs to be replaced before failure. …”
