38 problems related to vehicle speed control have been reported for the 1999 Ford Taurus. The most recently reported issues are listed below.
I have had three instances of engine races to 3000 rpm when stopped in idle and in gear. Dealer can't repeat problem and therefore hasn't fixed the problem.
Decelerates poorly (won't slow down) when removing foot from accelerator (gas pedal); especially speeds above 50 mph. Can be reproduced with the transmission in "od" after the car is warmed up. Might even be worse on colder days (less than 50 deg f). It's like the speed control is "on"; the rpms on the tachometer don't drop, and the car continues at the same speed or even accelerates! you can't coast down, it requires braking to slow the car down. It also seems to take longer to stop - when braking - because of the engine working against the brakes. On roads that have a slight decline, it requires you to brake often to maintain the posted speed limit. Driving this car is just unnerving; I'm not used to using the brakes so much. I've taken my car back to my Ford dealer twice for this problem. On the first visit (3/16/99), the service manager took my car for a drive and agreed my car had a problem. He then gave me an appointment for the second visit when I left the car to be worked on. Later that day, he called me at work to tell me apolgetically, that Ford considered this "normal"; needless to say I was very disappointed. He left me a copy of ssm#12066 (special service message) that states: "1998-1999 Taurus/sable 1998 & 1999 Taurus/sable 3. 0l 2-valve, 4-valve and sho vehicles calibrated with increased air flow at closed throttle to prevent tip-in-bumps. A result may be reduced deceleration feel and less engine rpm reduction at closed throttle with the vehicle moving. . . . No repair should be attempted for these symptoms as they are normal. " since Ford has an ssm that addresses these symptoms others must also have complained about this. My wife owns a 1997 Ford Taurus, with exactly the same motor and transmission and it does not have this problem. It decelerates when you lift your foot off the accelerator under all conditions. I've already contacted Ford by letter and have talked to them on the phone. I have little confidence that they will be fix it.
