Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2008-2011 Mercury Mariner has a dangerous problem with the power steering that Ford says they fixed when they didn't -- at least not 100%.

I received a message on my dash display "power steering assist fault" while driving. After parking, shutting off my vehicle, and then restarting my vehicle, my power steering was locked. The brighton Ford dealership assessed my vehicle and told me I have an issue with my torque sensor which causes the power steering to lock up. I looked up torque sensors for my vehicle, and discovered that torque sensors in many vehicles matching the same description as mine were recalled for the same exact malfunction. My car was manufactured during the dates listed on the recall as well. It is recall number 14S05. This recall is not showing up for my vehicle. Why could this be?

Received Ford recall #14S05 in July of 2014, for a "loss of electric power steering assist" in affected vehicles. The recall notice indicated that Ford would perform a "software update", or, "replace affected components for free of charge". took my vehicle to a nearby Ford dealership, had the recall "software update" performed on my vehicle. After the "software update" was performed on my vehicle, my vehicle suffered a complete loss of power steering assist, requiring the replacement of the entire steering column. This was the exact reason Ford had issued recall #14S05 in the first place and the exact components Ford said it would replace as part of recall #14S05. Ford has since refused to pay for, or, reimburse me for the cost of this repair under the premise that the "software update fixed the power steering assist defect". as a result, Ford continues to perpetuate increased risk of accidents and subsequent injury to owners of the affected vehicles.

Drove to work about 15 miles and shut vehicle off. Then started vehicle to move vehicle to another spot and steering was tight and on dash it said power steering assist fault. Was unable to steer car. Called Ford customer care because I wanted to know if my vehicle had been fixed with campaign14V284000 and was told campaign was closed.

My power steering went out and on the dash it said "power steering assist fault". I took it to the Ford dealership and they said the torque sensor went out and the electric steering column has to be replaced. There was a recall on the torque sensor in 2014, recall 14S05, and their solution was to do a software update instead of replacing the steering column. When I called Ford's corporate office about this they said they have not decided to pay for the steering column to be replaced. I am filing this complaint because the solution to the recall did not fix the problem because the torque sensor still failed and Ford should be responsible. I know there is an ongoing investigation about this issue and hopefully Ford will do the right thing and reimburse everyone that has had to pay for this to be replaced.

My wife was driving on her way home, and out of nowhere the steering felt weird, and while driving the car shut off. No power steering or power brakes (due to engine shutting off) and we do not know why this happened.

It started off when you get on the freeway you have to hold the steering wheel tight because it jumps in the next lane. And it's hard to steer especially trying to turn and guide it going straight.

Safety recall 14S05 -as a result of the recall Ford upgraded the software in my car in Dec. 2015, but three months later the steering failed. (the car was parked on a quiet san francisco street when I tried to start it and realized that the steering wouldn't work.) I first towed the car to my local mechanic, who looked at it for a week and then told me that it was related to this safety recall; he advised me to take the car back to Ford. When I re-towed the car to Ford dealership, they refused to honor their written commitment to repair the problem and instead tried to argue that because I got a software update, their responsibility was over. When I asked if the symptoms in my car matched those the recall was meant to fix, the dealership admitted the symptoms matched. They say they can't do anything B/C a "code" didn't trip. I also noticed that the recall says that software upgrades "may" fix the problem and should at least notify the driver by beeping. My car never beeped, but more importantly a software update that "may" fix the problem is not sufficient for safety! the steering issue should be fixed/replaced by Ford! Ford is negligently putting customer lives in danger. Moreover, Ford shouldn't be able to push the cost of a malfunctioning, core product feature onto customers. When I purchased the car, at the top of the market price for it, I was not told "in 50,000 miles you will have to pay several thousand dollars for a completely new steering column because this one will fail and people in your car may die." Please investigate as many consumers are complaining about how Ford is trying to push responsibility for recall 14S05 onto individual car owners.

Power steering failure while in motion. Safety recall 14S05. Failure required steering column and motor replacement. Flash memory had been re-programmed 2 years earlier and that did not prevent the failure. Ford would not pay for repair or discount the repair. Young adult driver temporarily lost control of the vehicle at the time of failure on a busy city street while turning. $1,223 repair estimate is attached.

I got a recall notice in the mail for the power steering that it could go out. Took it to a Ford dealership - autonation in white bear lake mn_ and they did a software update and closed the recall out as complete. Almost immediately the steering wheel began shaking intermittently and randomly. It got to the point it was shaking violently so I took it back in and was told the steering column needed replaced. Even though this was one of the options to do in the first place on the recall they said it was no longer covered and would cost $1300. I called Ford and they refused to cover it as well because the software update was done. Now it is not able to be driven safely until I can afford the repairs. It clearly is related to the recall as I know the 3 options were to update the software, replace torque sensor or replace steering column. I have read countless similar complaints online - yet autonation nor Ford will fix the car.

Vehicle lost all power steering while underway (extremely dangerous when vehicle lost power steering, lucky to have avoided a collision). Vehicle was "serviced" under previous power steering recall. Vehicle steering wheel would intermittently rock back & forth before final failure. Ford is claiming no responsibility for fix, after already issuing a recall for steering related defect. This is a dangerous defect in controlling/steering these vehicle's.

Steering wheel shakes and grinding sounds coming from steering column this happens when the vehicle is in motion or stationary. Local Ford dealership diagnosed as a faulty torque sensor which would result in a loss of power steering. Had a recall on the vehicle approximately a year ago because of loss of power steering due to the torque sensor. At the time of recall my torque sensor was not failing so the dealership only did a computer software update. Clearly the update did nothing to correct the issue with the torque sensor associated with the recall, however now Ford will not correct the issue with the vehicle. I have not personally lost my power steering yet in a situation that could have caused injury however there are a whole slew of complaints from people reporting the exact same problem. A sudden loss of steering is a big deal and very dangerous, it is something Ford should be required to correct.

Trying to edit complaint # 10823464. Please update recall 14V-284 was performed on this vehicle in stevens point, Wisconsin on 12/30/15. Service performed was a software modification that was described to prevent the vehicle from going into manual steering mode without warning as a result of torque sensor defect. 01/27/16 the power steering assist stopped functioning while driving and moved to manual steering mode, 29 days after the recall service was performed. A "power steering assist fault" warning display on the dash. I contacted Ford consumer line was told that recall on my vehicle is closed. The update was applied. Now I have to pay for a torque sensor, a cost of $700. My understanding of the recall on this vehicle was to prevent this problem. Now we have an error the "power steering assist fault" or with torque sensor, would this repair be allowed under the recall due to these circumstances? I was told the recall was closed and I may have to pay for repairs. I do not believe the initial repair was sufficient. We have never had any problems until this one happen on January 29th. This safety recall 14S05/NHTSA recall 14V-284 was performed on December 30, 2015. The National Highway Traffic Safety Administration website has several hundred common complaints the software update did not correct the problem. We feel we should not pay for any repairs with torque sensor at $700. This should be covered by the recall. We have made an appointment for service and is at location today at a Ford dealer. I call Ford customer service line at and file a complaint, case # 8728537 and was told to save my receipts in case Ford has a new recall that comes out to reimburse the cost of repairs. Please NHTSA, speak with the Ford about this. Request for a determination, if they feel they adequately met its obligation to remedy this recall and why the problem continues.
