2009 MERCURY MARINER Complaints

The contact owns a 2009 Mercury Mariner. The contact stated that while at a complete stop, the steering wheel was jerking independently. There was no warning light illuminated. The contact stated that upon starting the vehicle, the power steering assist failed to operate as needed. The contact stated that the power steering warning light was illuminated. The dealer and the manufacturer were notified of the failure and informed the contact that the vehicle was not included in NHTSA Campaign Number: 14V284000 (Steering). The vehicle was not repaired. The failure mileage was approximately 150,000.

Charcoal canister and purge valve defective stuck at open. Check engine light, dropped fuel economy. Forced vehicle to shut off engine and no power, stop on freeway at full speed.

The electronic power steering is not working and have already replaced the torque sensor twice. I need a ECM and steering column to fix it.

Purchased used car in what appeared to be very good condition. Within a few months, Power Steering Failure. Very difficult and dangerous to drive without power steering. Need car for work.

About 3 months ago, my power steering started to fail. After researching to find out the problem, we learned that my car does not have a power steering pump, as it is electronic. I learned that my car had a recall from Ford pertaining to the power steering failing. I called Ford and they told me that my car was part of the recall and was "fixed" in 2015. A month ago I took it to a Ford dealership to have them do a diagnostic on my car and they informed me that it was my power steering torque sensor, which I already knew this by researching the issue. The issue now lies in the fact that the part is on back order and there is no available date. I believe that Ford should have replaced the parts needed instead of doing a "bandaid fix" by doing a software update, which they knew would not be the fix to the problem. Ford got away with not fixing something that is very dangerous to those who drive the Mercury Mariners. Mine is an 2009 and it is now dangerous on the highways to drive. I would like to add that while driving my car now with this issue, my battery light comes on, which is also a known issue to Ford.

The PCM shorts out and fails when sparkplug and Coil packs replaced this cause the steering system to fail speedometer to quit and no transmission connection

Driving and my steering totally quit...almost wrecked it was so hard to control. Had not had any previous issues prior to this. I had my vehicle towed to mechanic and code that came up says steering assist has failed and will need to replace whole steering column assembly. There was no warning light...nothing! Upon my research, I see this is a frequent problem and there was a recall (1 million vehicles) but only for certain models, and of course mine is not one, in fact I haven't read any reports where the steering column was replaced, only reprogrammed and then the problem comes back. My car was manufactured at the Kansas City plant, which I have seen complaints numerous times for this problem coming out of this facility. Mechanic contacted Ford to inquire about the part...was told it was a 6 month minimum time to get the parts!! 6 months...am I just SOL for 6 months since my car cannot be driven safely? I purchased a Ford because they were not part of the government buyout...big mistake. At this point, I cant have it repaired with no parts. They know this is an ongoing problem, yet refuse to do anything about it.

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.

The power steering gets stiff as i go down the road after a ding from the dash and no warning lights

Electronic Power Steering System, which was part of a previous recall, and was allegedly fixed, but continues to experience the same loss of power steering. This is a continual problem, meaning that it is not a one time incident. Yes, the vehicle is available for inspection at any time. When the power steering goes out while driving, the steering wheel jerks to one side, and feels like a lock-up. The vehicle is still drivable, but can be dangerous in a situation where attempting to avoid an obstacle, could result in an inability to do so, because the maneuvers are being executed for a vehicle with power steering, so when it goes out, those same corrections will not successfully avoid a collision. The dealership is aware of the problem. They did a system check and insist that the steering column needs to be replaced, and that it has nothing to do with the previous recall, but it is exactly the same problem involved with the recall, therefore I do not believe they are differing issues. I believe the initial recall repair was unsuccessful, or the wrong fix. There were three or four options for fixing the issue. There are no warning lights that come on prior to the power steering going out, but a click can be heard however, at the exact moment when the mechanism for the power steering goes out. The same click can be heard when the vehicle is started and the power steering does come on. It usually comes on when it is cold outside. It will then go out once the car gets warm. I bought the car in January of 2000, and I did not experience the issue for a few months. When it did start happening, it was only once in a while - maybe every few months. The problem started happening more frequently with time, with the current status being that the power steering is predominantly not working.
