2007 Mercury Mountaineer. Consumer writes in regards to acceleration and console lighting issues and problems with back windshield wipers.

When braking the vehicle accelerates, when slowing down to a stop sign or a red light and it happens when parking forward or reverse. I recently purchased the vehicle 8/2012. I am very dispointed because I really like this SUV. I hope the dealer will fix this speed control problem free of charge because this situation could get dangerous.

The contact owns a 2007 Mercury Mountaineer. While driving 12-14 mph and attempting to slow down to a stop, the vehicle lunged forward. The contact depressed the brake pedal more firmly to stop the vehicle. The vehicle was taken to a local mechanic who could not duplicate the failure. Once while driving in reverse, the vehicle lunged forward and pinned his son between his vehicle and another. The child sustained arm injuries. No police report was filed. The failure had been occurring since 2008. The vehicle was taken to the dealer but the contact was unsure of what the dealer did to remedy the problem. The failure continued and progressed to a more consistent problem. The vehicle had not been repaired. The VIN was unavailable. The failure mileage was 50 and the current mileage was 50,000.

When coming to slow stop, the vehicle will lunge forward before completely stopping. This behavior started several months ago and was very random in the beginning, but has become more and more frequent - almost every time I come to complete stop. Vehicle also hesitates when gas is pressed and then surges forward. That behavior is very random at this stage, but car has done that over the past year. Because of the "lunging" at stops, I have taken vehicle to repair shop and they indicate the vehicle's computer needs to be updated. This appears to be a common problem with this make/model/year.
