Alternator/generator/regulator problems of the 2007 Ford Taurus



Three problems related to alternator/generator/regulator have been reported for the 2007 Ford Taurus.

car   Alternator/generator/regulator problem 1
Failure Date: 04/19/2012

I have already had the throttle body replaced 3 times on my vehicle. It lope, headlights dim/bright, and jutts. Also slight unexplained acceleration occurs, and occasional hesitation on acceleration. Fuel filter replaced, fuel pump checked out working properly, and injectors are running fine. Also alternator checked out good, new spark plugs, wires working fine, new battery. Mechanic cannot find anything wrong with the car, but it runs terribly. It`s loped since around 60k miles, and seems to be steadily getting worse. Also on third radiator. A friend told me it could be the ac getting low or charging, or possible iac motor going out, but there`s no real good way of testing it. Dealers keep telling me they won`t fix unless it`s for sure broken. Will take till I`m stranded till a mechanic will fix the problem.

car   Alternator/generator/regulator problem 2
Failure Date: 08/15/2010

Engine cranks easily but acts as though there is no fuel or spark. Gauges in the dash start to jump and tick. Generally car starts and runs fine after a few attempts at starting. Dealership said that alternator was bad and replaced alternator at Ford dealership and it did not fix the problem. Problem has been occurring weekly, once or twice a week.

car   Alternator/generator/regulator problem 3
Failure Date: 03/10/2009

2007 Ford Taurus 10/25/2006: with 23,774 miles I took the car to webster Ford for a knocking noise I heard coming from the alternator. They found parts were missing in the motor during production which resulted in replacement of the motor. (invoice #32124) 04/18/2007: at 30,308 miles I returned to dealer for noise coming from around the alternator. They replaced the tension control arm (which they damaged during the motor replacement in April 2006) and also a new serpentine v-belt (invoice #38704) there service bills state all parts and labor warranty are 12 months or 12,000 miles which ever comes first; good from the original date of service. 2/24/at 39,448 miles I experienced an electrical failure while driving, the battery light indicator came on. 2/25/midas checked engine found battery failure no other symptoms. Replaced battery $118. 79. 3/9/at 39,455 miles the indicator light "check charging system" comes on. Midas replaced the original 2006 alternator. A 2007 alternator was ordered but would not fit/work because it was too large. After replacement of alternator the indicator light" check charging system" came back on, $382. 32. 3/10/at mileage 39,348 took car back to webster Ford found to find the alternator ground wire, in an enclosed wiring harness assembly, that had 3 separate shorts. All 3 were split open (I have two of the pieces). The wire was twisted too tight which caused the splits, invoice #50848 $242. 46 the shorts happened either during production in 2006 or during the service at webster Ford in April, 2008. Total cost $743. 57.
