2003 Mercury Sable Owner Comments

problem #4

Throttle cable stuck, engine at 1800 tpm, engine revved to 2600 RPM, inability to slow vehicle, surging. Required hard breaking. Once car stopped, idle dropped to 900 RPM after 15-30 seconds. Happens with increasing frequency. Engine surges at start, revs to 2100 then to 2600. Inspected cable, throttle and cruise control cable point of entry to supporting bracket plastic shattered. Cable emits sound from binding. Took to Ford dealer, they indicated my vehicle was not part of the recall although the problem has been clearly documented with the same make, model, year and engine.

The contact owns a 2003 Mercury Sable. The contact stated that the vehicle accelerated independently to 25 mph after shifting from park to drive. The vehicle was taken to the dealer who stated that the idle iac valve needed to be replaced. The vehicle was not repaired. The manufacturer was not notified. The approximate failure mileage was 155,000.

I pulled up to a stoplight. When it turned green, I depressed the accelerator and the vehicle's engine revved as though it were in neutral. When shifted into any forward gear or reverse gear, it would not move. It was as though it were stuck in neutral. The transmission specialist said it was a common problem, knew exactly what it was, and quipped that he was surprised mine had lasted this long. Upon researching online, it appears that this is an incredibly widespread problem. In fact, Ford knows it is a problem as it has recalled two of their minivans that contain the very same transmission. It is the same part failing. Why does it warrant a recall in one vehicle but not another??

Driving on I-25 northbound, at 50 mph, the vehicle started to accelerate, with my foot off the accelerator. Went from 50 to 65...stepped on brake, brakes slowed/stopped the acceleration...pulled off at the first exit ramp. Looked under hood, for anything not correct...nothing visually detected. Did this one more time...3 days later. Have not experienced since.
