When the weather is hot (close to 100 degrees or more) and I am driving with the a/c - my vehicle on 3 occasions will not start after parking the vehicle and trying to restart it. The red padlock sign blinks and it won't start. At first it is trying to turnover but then will continually sound worse and all other warning lights go haywire. I leave the car alone for half a day and it starts up again like nothing happened. On the fourth occasion, the car stopped while driving, just a quiet shutdown and the car glided. This time it did not work for over 24 hours and then started up again like nothing happened. Multiple mechanics and also the dealership cannot figure out the problem because by the time i have it towed to shop, it works again. They did a full check on the car and cannot find anything wrong and there were no diagnostic codes. This issue happens when the weather is hot and poses a safety concern as now it is shutting off while driving and I become stranded each time. (First incident happened 8/25/18, last incident 5/14/22) Total of 4.

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.

The vehicle was in motion at a stoplight. The light had turned green, and the vehicle was breaking to stop behind the first vehicle. I pressed the gas pedal to follow the first vehicle and the car stalled. The car could not be turned back on or put in motion. There was no indication of a problem prior to this throttle body failure. The car was pushed off the road by 3 people and into a nearby parking lot. The problem that made the vehicle unsafe was a defective Ford throttle body. The reference consumer satisfaction program 13N03. I received the recall notice June 2014, but Ford only suggested a recalibration (not replacement). The recalibration was completed at Ford autonation on June 23, 2014. Ford had estimated a throttle body reduction in movability and not failure. The mileage of this Mercury Mariner on the date of repair was 142551 and the in-service date, 06/18/2010. Therefore, the reimbursement should be covered under Ford's extended warranty of 150000 miles/10 years. The repair was completed 06/08/2020. Ten days prior to the expiration of the extended warranty. Ford claims they will not reimburse for the throttle body failure. This was well-documented in the previous claim 13N03 and this case should be reopened, based on the fatality possibility of a throttle body failure with the original part that came with the vehicle, which was also re-calibrated per Ford's recall in 2014. This incident proves that Ford's re-calibration did not prevent failure of the throttle body. Asking for a recall for the throttle body for the similar makes and models still in circulation as it's a safety hazard and also reimbursement for this service for vehicles that had it completed.

Having two issues. The first one is the check fuel intake warning light comes on and my check engine light stays on. This appears to be causing my car to cut out dangerously at intersections as well as the wrench light to come in and my car 'limps' home.

While driving this vehicle we have stalling issues. The issues have happened while driving the car on the road while making turns and stopped waiting for a light, the vehicle stops running without warning. The car will restart after you have placed the car in park and restart. The dealership has not been able to duplicate this problem.

Vehicle electronic throttle body (etb) was replaced at veterans Ford dealership in tampa, fl due to this part severely effecting ability of the vehicle to run properly (several times). Customer paid for this repair. Sometime after 3/4/14 when NHTSA completed their investigation, we received a notice that Ford was replacing this item. Since we already paid for the repair ($381.32) at a Ford dealership, we tried to get the reimbursement that Ford owes us. We were informed we had to have the original receipt, which to this day is still packed up in storage if we have it at all because we moved from fl to nc and are still involved in buying a new home. The bottom line is Ford (Corp) is refusing to honor their agreement to reimburse customers. The craziest part of this whole dilemma is that Ford has and controls 100% of the information needed to process our reimbursement, but absolutely refuses to do so without the original receipt. I could understand if we had this repair done at some unrelated, third party service facility. However, we went to a Ford dealership and they have record of completing the repair and us paying them for the repair. So again, Ford has all the information (proof) in their possession to take care of this reimbursement, but refuses to do so. I have called the customer (dis)satisfaction department at Ford corporate, but that is like talking to a brick wall as far as anyone having in common sense, accountability or decency to do the right thing (certainly any kind of good will is lacking in that organization). So here I am having to complain to the NHTSA to get Ford to do what they promised in the first place. I look forward to a timely reply letting me know you guys have this handled. Additionally, Ford should be reprimanded severely for such [xxx] behavior and attitude. Maybe a consumer reporter needs to get involved in all this. Thanks.

During normal driving on the highway the engine lost power, the wrench light on the dash lit. The vehicle sputtered and suddenly decreased in speed, making for hazardous driving conditions. I moved to the side of the 4 lane highway and into the breakdown lane. I placed the vehicle in park, the engine idled roughly. I turned off and restarted the car and the symptoms were gone. A week later the same trouble returned. Please press fmc to resolve at no-cost to consumer the obvious and dangerous manufacture defect with a recall on the affected parts/system.

Was going home from work, about 20 mph, car sputtered and stopped accelerating on ramp, engine and wrench light came on. This had happened before so I knew to turn the car off and back on to get my car to work again. But alas, I am driving at about 30 mpg for only 2 minutes and it happens again! I was again on another ramp, completely blocking traffic. Thank god I was not yet on I-95 going at a high speed, or even worse with my child in the car. If I ever get in an accident with my child and we are injured because of this, my family will sue the heck out of Ford. Has to call my husband to drive the car to the dealer after I pulled off the road, I was shaking too bad to drive.

Slowed to make a right hand turn into a parking lot and the vehicle stalled. There was no warning of an impending stall and no console lights came on other than the battery light and the oil light. The incident did not create an error code in the computer system as I took the vehicle to a Ford dealership for service and to check for any issues with the vehicle. Ford repair shop found nothing wrong with vehicle upon inspection and said there was nothing they could do without an error code in the computer system. A stalling incident occurred again on 3/18/14. In this instance, again there was no warning. I had just exited off of the highway and was accelerating after a stop sign. The vehicle stalled in the middle of the road. Again, only the battery light and oil light came on.

Twice in two days while speeding up to get on highway my Mariner looses complete power and the wrench light comes on. Lucky for me it was just before I was turning on to merge. Seconds later it would have been a serious accident, due to the sudden stop. I had to shut the car off and start it back up in order to get going again. After reading #PE13003 has been file for the same exact problem with same make and model. Someone better react before someone looses a life. This is horrible.

In 2011, while driving at approximately 60 mph, I pressed the gas pedal and could not accelerate. The engine stayed on but I could not accelerate. I was able to turn on the hazards and pull off to the side of the highway. I turned off the vehicle and after waiting 5 minutes I restarted the vehicle and the gas pedal was working. Then again in October 2013, I was driving approximately 30 mph when I lost acceleration capability. This time the throttle body indicator light was displayed. I took the vehicle in to a mechanic and he stated that nothing registered on the computer as a malfunction. He looked at the intake valve and could not see any build-up. In January 2014 this happened 3 times and I was able to restart the vehicle and proceed. However, on January 11, 2014 after the malfunction the vehicle did not reset immediately now the check engine light is displayed.

- Austin, TX, USA

Was at stop light completely stopped. When the light turned green, I stepped on the accelerator and my car did not accelerate. The engine light and another light came on. I tried multiple times to move the car and nothing happened. I powered my car down and restarted it, at this time the car started moving again when I pressed on the accelerator.
