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.
On October 18, 2018 I received the power steering assist failure error on my instrument panel when turning on my vehicle. I had driven it earlier in the day without issue. Previously I had the occasional warning noise and quick flash of an error (too quick for me to read all the way) and would have momentary difficulty turning. This issue makes it almost impossible to steer the vehicle. Research indicates that it is most likely a malfunctioning torque sensor. I reached out to Ford after learning of recalls for the 2009 model year. I was informed that my VIN was not included in the recall. Ford was unwilling to assist with the cost of repairs in any way. Their suggestion was to keep the receipt on the slim chance that the recall would be expanded. This is unacceptable. Had I been on a highway when this occurred it could have been fatal to myself or others. This repair will cost in the neighborhood of $1000 or more. I will need to have the work done at a dealership to ensure the repair is done correctly and that Ford won't give me reimbursement issues should the recall be expanded. This occurred less than a year after the fuel inlet valve failed on the vehicle, causing it to shut down while driving and rendering it unable to be started. The rear hatch has not been able to be opened for over three years because of an issue with the latch. I have had issues with the climate control system and well. There were issues with air conditioning when I purchased the vehicle (April 2015). The issues were not apparent previous to purchase because of the weather at the time. Within a month the weather warmed up. When I attempted to use the a/c it was only blowing hot air. The dealership was willing to fix the issue free of charge because of the circumstances. However, the issue is occurring again even after having an a/c recharge performed.
The vehicle randomly shuts down while operating on the highway between 65-75 mph. There is no warning and it becomes very difficult to steer the car. After waiting for 10 to 15 minutes the engine can be restarted and all seems to operate, until it happens again.
While unit is running on road engine still running car stop for absent of power but engine keep running, pressing gas pedal will do anything , you have to turn engine off wait and turn engine on back in order to kept driving , this very dangerous because this happens in the middle of the hay way at any speed , please consider a recall we almost get kill by a rear impact if we did react fast . Update does not fix situation, this a troubleshooting from factory and they now this very clear. This happens in hay way 147 going north to south at 9. 10pm on 06/13/2018 where we were driving speed limits of 55mph.
Tool light comes on and car loses power in traffic, very, very dangerous. Dealership updated with computer but vehicle is still doing it. Please do a recall Ford.
While in motion the car will stall causing me to pull off to the side of the road, turn the car off, then back on in order for it to work again. This happens every 10-15 miles and its really unsafe! I believe it is a defective throttle body and needs to be fixed ASAP before I can continue driving it.
My 2009 Mercury Mariner stalls while its idle, at a intersection or just waiting. It stalls then I started up right after it stalls.
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.
During normal highway driving conditions, car suddenly stopped accelerating, could push the accelerator all the way to the floor and get no power. Engine did not stall out, but would not provide power. Was able to pull over and turn off car, then turn back on, and problem was gone. After another 15 miles or so it happened again. Took the car to the dealership and they reported that it was a bad throttle body and had to be replaced.
Driving home from work the car went into "limp mode", pulled over to side of road, called for tow and had car taken to shop for diagnostics and repair. Shop determined it was faulty throttle body ( there were over 700,000 orders for replacements on website at this time)part was on backorder---came in, was replaced and I paid the bill of $720. 60 for parts, labor, towing and taxes. I got letter from Ford that part is now a recall item so I take the bill to kerry Ford in cincinnati, OH and they take all of my info and send me a check for $167. 85 and tell me too bad for not having work done at Ford store, that's all I am going to get. This does not even cover the cost of the part alone. So as a stranded motorist, I was supposed to think of a Ford dealership first instead of safety first and getting my car repaired.
While driving approximately 35 mph, the vehicle lost all throttle. The engine continued to run. Pulled over and placed the vehicle in park. Pressed on accelerator but nothing happened. It would not rev the engine. Restarted the vehicle and the throttle worked properly. This happened twice today.
This actually first occurred on Friday. I was traveling on the thruway at about 65mph when the car felt almost like it downshifted and then I totally lost acceleration and the wrench light appeared on the dash. I limped to the side of the road and the car jerked and sputtered before I shut it off. After a few minutes I restarted the vehicle and it sounded like it was flooded at first then it turned over normally. I was an hour from home and made it back without further incident. I took it to the dealer the next morning and it did not show any codes. They suggested I replace the purge valve, and as I had a busy week of work related travel scheduled I went ahead and had them do it for $120. Better safe than sorry. Right? today I get an hour from home and it happens again. I call my dealer and they suggest I find the closest Ford dealer and take it there immediately. Closest Ford dealer couldn't take me for 2 weeks!! I was an hour from my destination, so I decided to chance it. I drove about 20 minutes and it happened again. Same exact scenario. I started it again, got back on the road and drove 10 minutes and again, except this time the engine light also came on. I called roadside assistance and was towed to a garage. I am 2 1/2 hours from home and driving a rental. Garage will diagnose and hopefully fix tomorrow. Service tech said if he had to diagnose without a code he would say throttle body! it also sounds like this is not covered by my 5 year/60k warranty either. With all of the similar stories I have read online Ford needs to be forced to do a recall and reimburse us all for our expenses.
2009 Mercury Mariner with about 90,000 miles. Was on the freeway driving about 65-70 mph when suddenly the power to car cut off - was not able to accelerate vehicle; drove to right side of the road. Car was still on, but gas pedal would not work, wrench light was on, car idling very roughly. Turned car off. Turned car back on, wrench light was off, drove another 30 minutes to destination without incident. In the two hour drive home, the car cut off five more times. I heard a bell alert audio sound a few times, but the only light that came on was the wrench just as the power cut off. The very last time it happened, the engine light came on, and stayed on even after restarting the car. I feel very thankful to have got home alive and without getting into an accident. Dealer recommends a 90m service package ($547), a diagnostic test ($104), and possibly a throttle body and/or sensor ($300-ish).
The vehicle has stalled while in motion 6 times now, while stopped 3 times. Stalled once while driving upwards of 40mph. I had to stop in the middle of the street, put emergency blinkers on, and restart the car. Vehicle seems to spontaneously falter in acceleration and loses power. Turning off ignition and restarting engine fixes the problem but it will then reoccur at an unknown time. Some incidences have been in the same day, others have been up to a week apart.
Driving along and unexpectedly engine goes in limp mode with no warning and no acceleration- extremely dangerous as was driving on expressway when this occurred.
Driving at highway speeds when the vehicle lost all power. Was able to the vehicles momentum to pull to the side of the highway. After turning the car off, waiting, restarting the vehicle, I was able to restore power to the engine to return home. Turning left through cross traffic, the vehicle lost power again. Was able to quickly turn the vehicle off then on again to restore power and move out of the way of oncoming traffic. The dealer diagnosed and replaced the throttle body for being defective. The vehicle is no longer under warranty and I was required to pay. This is the second time this problem has happened. 1. 5 years ago the same problem happened and the throttle body was replaced under warranty.
Recently purchased 2009 Mercury Mariner (Ford escape) has three times simply quit while driving at low speed and the throttle is gently pressed. Latest incident was while traveling uphill with two grandchildren and a 18 wheel truck on the back bumper. Luckily my wife had the presence of mind to shift to neutral, re-start the engine, and accelerate away from the truck. No error codes have been set during these three events.
On June 11th, 2013, I was turning a corner and my vehicle was not allow me to accelerate. I was able to pull over to the side of the road and turn the vehicle off. I sat with the vehicle off for about five minutes and was able to start it back up. I then drove a few feet, and it stalled again. I then turned it back off and let it sit for a few more minutes, in which I was able to restart it and drive home. He same problem has occurred at least 5-10 more times since then. Since then I have had the throttle body cleaned, put the issue still exist. The most recent occurrence was this morning at 30 am. I contacted after-market auto part stores and they do not carry a throttle position sensor. I contacted the local Ford dealership and they told me that the part was on back order and it would take some time to get the part in.
2009 Mercury Mariner engine stalls, surges then no acceleration. Coast to side of road, while trying to not get rear-ended. Engine still runs, is extremely rough. After turning the ignition off, then wait and restart, runs okay. This has happened on many occassions in past month and half. I contacted Ford dealer and service guy says it is most likely the throttle body starting @ $500 repair not covered under the warranty. Happens at any speed. From start or just while driving. First incident 5-31-2013.
I was driving through a town and the car cut out and lost all power. I steered it off the road safety. It restarted just fine and I took off again going four blocks were it died instantly in the middle of the road. It is now in the shop to figure out what caused stalling in the car, and then allowing it to restart and continue down the road. Very unsafe with traffic behind me and oncoming to be stalled on a curve on the road.
As my daughter was driving on the freeway, the engine suddenly lost power and she had to work her way to the side across 3 lanes of heavy traffic with no power. Our mechanic replaced the throttle body at our expense. The news today indicated that you were investigating the circuit board which controls the throttle and we wanted you to know that this problem was a threat to her safety and appears to be occurring to many people. This was the fourth time the vehicle has stopped while driving.
I was leaving work and driving down a road at about 50mph when all of a sudden my car jumped and I then was coming up to a red light so I was braking and behind a car. At the red light I was a few inches from hitting the car because my car kept jumping forward. I then got scared and turned my car off and back on and it was driving fine. Then all of a sudden it did the same thing and I couldn't accelerate I would press on the gas and my car was just shaking and losing speed and wouldn't move. Thankfully I didn't drive the highway home that day.
While driving the car will it suddenly stop receiving any fuel, car does not necessarily stall, it is very dangerous, because I will have to pull over shut the car off and it will restart, the wrench icon will come on, sometimes the engine icon, this at first was random, no pattern, once on the tobin bridge in boston, with very heavy traffic, thankfully was able to pull over out of the way, it would happen randomly for a few months and now it happens so often I am afraid to drive it, I have no money to bring this to a garage as I fear it will cost me way too much to fix, very disappointed with the vehicle, along with this issue the heater,ac fan only works on high, being a widow with very a low paying job I bought this and am still paying over 300 a month I am at a loss, there must be some way I can get this fixed at no cost to me, this vehicle was the first one I have ever financed and it turns out to be a lemon.
When being aggressive with the accelerator the engine stalls and the accelerator stops working forcing the driver to pull off of the road. When bring the car to a stop it jerks forward until it is put into park, still the accelerator does not work no matter how pushed. After turning it off start up takes longer than usual and either the little wrench or the engine symbol appears. After taking it to a mechanic it is diagnosed that is has a bad electronic throttle and it will have to be replace. Prior to this there has not had an accident, instance or work done that would cause this.
Was driving down country road and all of a sudden felt then engine what I thought was kick out of gear. Had no acceleration at all. Pulled off road and the vehicle was running in a rough idle, but still could not give it gas. Once placed in park the idle leveled out and still no acceleration. The wrench symbol was on. I stopped the engine and waited 10 minutes then restarted engine and everything was ok. For about 3 months. I took into the Ford dealer only to be told there was no code and they could do nothing without it. Problem has gotten steadily worst. And now it is at point where wife can not drive her car! I am driving it and finally yesterday the engine light came on. I ran it to autozone where they confirmed the dreaded p2112 code. I took it to the Ford dealer today figuring alright less than 5 years old and 42,000 miles I would finally get it fixed. No go! although for $106 they did confirm what autozone already told me that the throttle-body was shot and would cost another $430 to fix. I promptly called Ford customer care line and was told that they would contact the service manager at my Ford dealership to work out a payment plan for me to get it fixed still at my cost. This is crazy that I payed over 26,000 for a vehicle that I still owe 11,000 on and under 5 years old with 42,000 miles and this is my 3rd major problem with it. . Have already had the engine pulled apart once to be fixed and one of the drive shafts had to be fully replaced. This is unfortunate but will be the last Ford I ever own!!!.
