2008 Mercury Sable Owner Comments

problem #10

  • 75 miles


While on cruise control on a 6 lane divided highway the car suddenly accelerated from 72 to 85+ mph. Brakes did not disengage cruise control and could not slow down car. I had to shut the engine off to regain control and with flashers on I managed to get to the shoulder of the road and stop the car. Tried to restart the car to establish if condition cleared up, but could not. Had car towed to Ford dealer who was unable to duplicate the condition the following morning. They changed the mass air sensor but said it was unrelated to the acceleration problem.

Unintended acceleration resulting in an accident car rev'd on it's own and bolted forward while at a full stop at a red light and hit the car in front of it. Car was driven in twice and towed in once to the local Ford dealership, over the course of the 2 years prior to the accident, with the same complaint. They have not been able to find anything wrong with the car. Cause unkown. Problem is intermittent. After doing some online research I've discovered that there have been similar complaints. Tried to attach repair invoice and insurance claim, but "select image or document link " button below is not working.

The contact owns a 2008 Mercury Sable. While driving at a low speed, the brake pedal was depressed and the vehicle accelerated independently. As a result, the contact crashed into a light pole and the air bags failed to deploy. A police report was filed and no injuries were reported. The failure recurred on numerous occasions. The vehicle was taken to multiple dealers who were unable to diagnose or repair the vehicle. The manufacturer was not notified of the failure. The failure mileage was 35,000.

We were stopped behind traffic, and as we slowly started to proceed, the car surged at a high rate of speed, and as the brakes were applied, they either were not working or else it was the ABS coming on. This was a dry, sunny day-no moisture on the road-of course that would not have had a bearing on why the car surged/accelerated. Then the car shut itself off completely. We then got it started again, and nothing happened getting it back the aproxx. 4 miles back to home-all was normal after the incident all the way to home, though it has not been driven since. It has been reported to Ford hq's and to the dealership we purchased from.

There were two separate incidents with this same vehicle. Incident #1 with first driver: At about 5 mph, the gas pedal was pressed significantly down. The gas pedal then stuck down in that position and the car started to quickly accelerate. After a quick tap on the gas pedal, the gas pedal started to operate normally. At no point was the cruise control on. We took our car in to the local Ford dealer. They inspected the car but didn't find any problems. Incident #2 with second driver: A couple of months later (estimated mileage 38,000), we were driving at about 45 mph and I pressed the pedal down almost all the way. The gas pedal stuck again and the car started to accelerate quickly to about 65 mph. I am not sure whether cruise control was on or not. I shifted out of drive into neutral while the engine was at high RPM. After aggressively stomping on the car pedal, the gas pedal started working again normally. I shifted back into drive and the car then drove normally. The first driver was in the car when this happened. Both drivers have about 35 years of driving experience. This is a very serious issue that needs to be investigated! in our case, no one was injured but with less experienced drivers it could have been much different.

2008 Mercury Sable AWD had an electrical issue[melt down] that required replacement of the main electrical harness. Then in September of 2008 a sudden acceleration problem caused it to jump a concrete parking lot barrier and travel down into a drainage basin--40 feet. $9000+ damage. Repeated attempts to Ford has fallen in deaf ears. Updated 05/12/10 updated IVOQ 05/17/10.

On a 2008 Mercury Sable, on two separate occasions when the accelerator pedal has been fully or near fully depressed, it has become caught under the driver's floor mat, causing the engine to continue to race even when all pressure has been removed from the accelerator pedal.
