2006 Mercury Mountaineer: jerking or lurching

Filed Apr 22, 2021 · Acceleration, Transmission · MN

My car will jerk as I'm driving rpms going high while no speed is picking up. With jump out of gear when at stop light. Loud grinding noise from tires could have foot all the way down on gas petal and go no faster.

My 2006 mercury mountaineer has intermittently jolted or lurched forward when stopping for lights and stop signs after speeds over 30 MPH. Hasn't gotten away from me but feels as if I am going to hit something or someone ahead of me. Extremely scary when people are in cross walk. I took my car to the ford dealer shortly after buying it used. The dealer checked it out and denied it was happening. That was years ago and tonight I saw numerous complaints on another website about this problem. Was looking because now I am getting a grinding noise from my wheels which persists after a brake job that didn't fix it as I thought. Both problems are separate but I see a pattern of them on this vehicle now.

Tl* the contact owns a 2006 mercury mountaineer. The contact stated that while driving approximately 50 MPH, the radiator started to overheat. The driver was able to continue driving and added water to the radiator. The vehicle was not inspected by a dealer nor repaired. The manufacturer was contacted and they advised him that the failure was caused by normal wear and tear. In addition, he noticed that when shifting from park to reverse, the vehicle would hesitate and jerk violently into the correct gear. The failure mileage was approximately 53,000. The VIN was unavailable.

My car has had a continuing problem with the transmission. It shifts roughly and lurches when beginning to move. For example, when stopped at a stoplight, and then beginning to drive, it will lurch, jolting the passengers. Our driveway is sloped toward the street. When I park the car, I always set the emergency brake as well. The car always rolls a few inches before the brakes lock, even though it is stopped and in park. On sep. 4, 2009, my mother borrowed my car to go to lunch. She couldn't find the emergency brake release. She put the car in park and got out to locate the emergency brake. She found it and released it. The car popped into reverse and rolled backwards to the street. The door knocked my mother down and she hit her head hard enough to sustain a closed head injury with minor bleeding in her brain. The car rolled across the street, over the curb and hit a neighbor's poplar tree. The entire tailgate was destroyed, there was some interior damage and the frame was warped. The tailgate had to be replaced, the bumper and trailer hitch had to be repaired and the frame straightened. My mother was in hospital overnight and had to have two ct-scans. She still has headaches and transient dizziness. We are just fortunate the car didn't run her over, hit a pedestrian (there are a lot of walkers in our neighborhood), hit a car or a neighbor's house.

My 2006 mountaineer has transmission problems. While coming to a stop at a light there is a loud "pop" or thud like noise as if the transmission is popping into place. Also transmission slips when going forward. It jerks especially at low speeds such as pulling out of a parking space. There is definitely something wrong with the transmission. Poor design or manufacturing but definitely something is wrong. You feel like you have been struck from behind when the popping/thud noise occurs at a light. Very unsettling. Also car lurches forward when pulling off from a standing position such as at a light and you feel like your going to hit the car in front of you.

2006 mercury mountaineer. The transmission has problems. It punches in and out of gears, makes a loud grinding noise and pulls the car to the left. It has problems going into reverse. It does not happen all the time but I would say about 3 to 4 times a week. It is not safe to drive when the car does this. I am driving my 1 year old in this car and I have to concentrate so hard to make the car go straight and to put minimal pressure on the gas pedal so it doesn't jerk us too hard. It is at the dealership now and from what I have read online they will try to put a bandaid on the problem until the warranty runs out! This car only has 26,000 miles on it! I just bought it used about 8 months ago.

Transmission problems that resulted after recalibration in response to recal notice. Vehicle now lurches forward by itself when stopped at a traffic light. One needs to stand on the brakes to prevent vehicle from striking other vehicles.

The transmission in my 2006 mercury mountaineer has "popped" into reverse twice once it was placed into park, causing it to roll backwards. It also rolls forward and backwards when placed in park until it "catches" and finally locks in place. When climbing hills or steep grades, the transmission will surge, and when coming to a stop, the transmission will shift hard and jerk.
