Having a problem with our low mileage 2008 Taurus. When on the interstate and it gets up to 70mph, dash goes bezerk–can’t get any info–no speed, gas gauge, etc. (Doesn’t have this problem around town.) After this, when the car comes to a stop, it takes it forever to get back up to speed. Took it to trusted small town mechanic who knows what he is doing–he says car didn’t show any codes. He felt the computer was out of whack and straightened that out. He said if that didn’t work, take it to the transmission place in nearby larger city. He feels it could be the OSS.
Transmission place can’t find anything wrong. Says car shows no codes. I am 99% sure no one drove it on interstate. Place has a great reputation but is understaffed.
Take it to the Ford dealer. They kept it over a week–and guess what??? They couldn’t find anything wrong with it and it showed no codes. When I go to pick it up I am not happy with the shrugged shoulders and ‘we can’t find anything wrong with it’ answer. I ask if anyone even drove it on the interstate. Eventually manager comes out and goes for a ride in it with my son. Within 2 minutes of it being on the interstate it does exactly what we have been saying it does. Manager comes back and tells guy at desk it is the OSS and the engine is misfiring. I hear him say that when the car stops, it still thinks it is in 4th gear.
After over 3 weeks at dealership and lots of excuses and missed promise dates and what sure sounds like outright lies, nothing has been done to car. I pick up car and we go back to transmission place because we feel they really are our best option–great reputation.
Message there is that it could be OSS itself, the wiring, or the computer–there’s no way of knowing. We call another Ford dealership in another town–they say they won’t work on anything that doesn’t throw a code. They want to replace the whole transmission.
What do we do? This has always been a dependable car and son needs it for work. Please advise.
