2009 Mercury Mariner transmission problems

Filed Feb 9, 2023 · Steering, Transmission · IL

I have been intermittently losing power steering. The code is B1342. After researching, it looks like Ford is aware of this problem but is unwilling to fix the issue. This fix must be done at a dealership since it is a software issue and going to cost $2,000. Obviously losing power steering when going at fast speeds is incredibly dangerous for myself and others. There is no check engine light that comes on when the issue arises.

Driving my 2009 mariner premier about 35/45 MPH when wrench symbol comes on indicating throttle control powertrain / transmission problem car is not accelerating properly and transmission is jerking when I step on the gas pedal and the car shakes vibrates and feels under powered. Got home and parked it. Started it up and now check engine light is also on. Is this covered by the recall for extended warranty from ford ?

I am getting continual throttle body errors on my 2009 mariner. It goes into low power mode so I can "limp home". It happens mostly on highways when I need to "punch it" and get alot of acceleration.

On 1/1/2016 I was driving on 495 w in queens, ny heading back to manhattan where I live. Out of nowhere the car began jerking, a wrench light on the dash panel came on (which I never saw before) and I could tell the car was decelerating. I tried hitting the accelerator again, the car would jerk, the engine was revving but was barely moving. I knew I had to pull over and luckily I was able to navigate to the shoulder of the road. This was an extremely dangerous situation. I am a confident driver, however, a less confident or timid driver most likely would have panicked and gotten into a potentially serious collision.

While driving down the road anywhere from 20-55 MPH, the car seems to stall out and the accelerator no longer works. You have to pull over and shut the vehicle off and it will start again. Sometimes the same problem will occur again within seconds, minutes, or days later.

Normal driving when suddenly there was no acceleration & the wrench light came on in the dashboard. Car was running but there was no acceleration & idled roughly. Mechanic put a diagnostic on it which read p2112 throttle control actuator system stuck closed. Binding throttle body stuck closed. There was no warning and the incident was very scary since I could not get out of the way of traffic. The car would go about 1mph until I was able to pull off the road. When the car was later shut off and restarted, acceleration returned. This is frightening as you do not know when it could happen and could cause a serious accident.

Transmission fluid leaking from left hand halfshaft seal on my automatic transmission. Took into shop to have it diagnosed, found out something is wrong with the bearings do to low fluid. Then I find out there is a service kit available for this seal issue, however we have not received any notice of such service kit being available. I'd like to know who is going to cover the $2500 its going to cost to have my transmission fixed as opposed to a few hundred dollars it should have cost me had I been aware of this service kit.

I was driving at 45mph when all of a sudden, the car stop running. I had to pull over and cut the car off. I started the car again and it went about one mile before it cut off again. Then a wrench symbol came on the left side dash board. I drove the car home and it cut off on me three times before I could get it home. I look in my car book to see what the wrench symbol means and it says that it is the throttle control/powertrain.
