2010 Mercury Mariner: jerking or lurching

Filed Aug 13, 2021 · Engine, Transmission · PA

I was driving when it felt like the vehicle was reving in park then the "wrench" icon appeared on my dash. I went a couple blocks & my vehicle felt like it wasn't shifting automatically as it should. I pulled over & turned it off. It started right back up with no lights on, I went half a block & stopped at a stop sign but while stopped the engine reved up. I was worried I was going to be in an accident. Then the "wrench" light came back on, since I was close to home I figured I'd just try to get home. About another block, the check engine light came on & was making strange noises. I kept my vehicle at about 5-10 mph & got it home. My car was very jerky.

After receiving ford's recall notice 16s41/16v‑777 (fuel delivery module potential leak), my husband & I took our 2010 mercury mariner to lebanon ford to perform recall "repair". We were not having an issue with the mariner, but we were following ford's instructions (via their mailed recall notice to us) to have the recall done. Now, our mariner is messed up! It now won't start without a delayed crank (we have video recordings of how long it now takes for our mariner to start!) & sometimes while driving, the mariner jerks (both problems seem to be as though the car is not getting fuel). We made a 2nd trip to lebanon ford after informing them of the issue they created, but they did not fix the delayed crank issue or the car jerking issue! Lebanon ford service is stating they can only perform the recall repair "according to ford's guidelines". My husband asked lebanon ford if the old parts could be put back on, but lebanon ford said they had to send back the old parts to the manufacturer. So, now our once nice mariner has significant issues because we had a recall "repair" done! We regret having the recall addressed! Prior to the recall "repair", we had a nice mariner with under 60k miles. Now, we have a mariner with problems due to recall. It's not a repair! It's damage! Further, they're not offering us any fix to the damage ford did to our car.

I was driving my 2010 mercury mariner premium fwd to my mothers for christmas '14 when the engine light wrench came on and I felt a loss in power. Luckily I was near a rest stop and I shut off engine and let it sit after running a vehicle health report. Report said: urgent power train malfunction / reduced power. After restarting the vehicle, it seemed fine. This was when I still had about three hours left of driving in my eight hour drive. When I was about an hour away again the light came on and the same power reduction occurred. I took it to be looked at to the local ford dealer near my mothers and was told the valve body needed to be replaced. This was at 74,000 miles. So I did. I had this happen once before (I had 58,000 miles on it) when driving to a shopping center after driving 45 minutes on the highway from home. Only happened when driving long distance. When I got off the exit, it jerked and quickly stopped and I had to pull over. If a car was behind me it could have caused an accident.. I drove it to the dealership and was told that I had a couple recalls (computer updates) and a service extension for the throttle body. Should fix the issue so it won't happen again said the mechanic. Transmission fluid was flushed cause it was burnt also. Had no issues afterwards until my christmas trip. I feel I could have been in an accident and seriously hurt if it had jerked while changing gears on a busy road. I would like to know why there is a throttle body recall but not a valve body recall? If these issues can cause a quick jerk or lost power causing a quick slow-down, seems like there should be a recall for both. It appears I am not the only one with these types of issues after googling the issue. Seems like its time to get these transmissions fixed correctly before someone is killed or seriously injured! Please recall now b4 it's too late!

My 2010 mercury mariner has started jerking when I attempt to slow down. It is jerking unbearably hard. I took it to a local garage, had both front and back brakes replaced. That did not fix the problem. While the backend of the car is jacked up, the back right wheel will still turn while holding the brakes??? The jerking of the car is almost as if the car is skipping a gear or trying to switch gears. The car is also making a whinning sound. I feel as if this is a safety issue that ford should be responsible for. This is my second ford SUV with my first being a 2002 ford escape and I had a lot of "mystery" problems with it that no one could fix!!!

I was driving along on the highway (I-77 n) and all of a sudden my car started to jerk. The wrench tool light lit up on the dash board and the car immediately began to loose speed. The change in power and speed was quick and I had to quickly check the surrounding traffic and pull the car over to avoid and accident. After pulling over to the side of the road I cut the car completely off and it started back up. I took the car to the dealer where I purchased the car and I was advised to replace the filter. I purchased a filter from ford and my car ran smoothly for about 2 weeks. I would push on the accelerator but it would not accelerate. Each time the wrench tool would appear and the engine light would come on. I have lost speed in the middle of an intersection. After my car started to cut off again following the installation of the new filter I took the car back to the dealer and was instructed to purchase throttle body spray. They cleaned out the throttle body and the car drove fine for a few days until I began experiencing the same problem. Some times I would have to cut my car off a few times and restart it on one round trip. I keep regular maintenance on this car, changing the oil and rotating the tires, etc. I purchased the car in december 2012 because the car I had over $2,500 of needed maintenance. I needed a reliable car to get around as the primary transportation for my family. I took the car back to the dealer a few times and they explained the code and explanation of the problem: trouble code p2111, throttle body actuator stuck open and closed. I really hope this investigation is expedited and that ford recalls the mercury mariner 2010 due to the faulty throttle bottle. I have had zero maintenance issues with my vehicle other than the throttle body issues.

While my wife were going out to dinner we were driving on the highway at 45 MPH. I noticed a yellow wrench warning light appear on the dash. The car started losing power and began jerking. I could not accelerate and the speedometer dropped to 0. I coasted to the shoulder and stopped. I had to have aaa tow the car to my mechanic. He ran different tests and the readout he got from the computer was the throttle body assembly. He has a priority order for the part and said there is a national backorder on this part. I have an extended warranty with (nac) and they told him they will not pay for the part. I have to pay close to $820 for the part and labor. Ford has known about this problem with the 2010 mariner but will not have a recall. Do people have to die before ford motor company acts? This is a disgrace for the consumer.

I was driving at about 25 MPH when the car suddenly lurched forward, then began rapidly decelerating. I had to get off the road and coast to a stop. I turned the car off then restarted it and everything seemed fine, but the problem happened again later that day and several more times in the coming weeks. It has happened at various speeds and under diverse conditions. It is intermittent and unpredictable. After nearly causing an accident on the interstate due to this occurrence I am now limited to surface streets and only when I have no other option but to drive my car. After doing some reading it seems that this is a known defect with the throttle body and I worry that even if I pay out of pocket to have it repaired I will only be buying another part with the same defect. My hope is that ford will issue a recall of the vehicles for which this is a known issue!
