Check Engine Light On problems of the 2009 Ford Flex

2009 Ford Flex pcm. While accelerating off ramp onto interstate, mph 70, the Ford begin to shank violently then suddenly stops. . . . . . . . . . . . . . In the middle of traffic/interstate in the middle lane at 70 mph. Flex goes to shop and 3 coils are melted, converter needs to be replaced, and pcm needs to replaced. This is a serious hazard and needs to be looked into as there are many many post and complaints about the pcm. The safety of the Flex and it's passengers are in grave danger when this happens as it is out of no where. 70 mph on an interstate at a sudden stop will kill someone. No check engine light appears until after the fact. This is a Ford malfunction that needs to be recalled by Ford and addressed instead of TSB's before an individual is seriously hurt.

Driving stopped at a stop sign noticed the wrench light on (happens often while this happens will not accelerate like normal until it hits 2-3rd gear). I press the gas to accelerate after making the turn I had to make another turn about 1/4 mile up the street. I released the gas to make the turn but my car kept accelerating it was not going very fast but the engine was accelerating pushing the rpms up to 6000. My foot was not on the gas and nothing was pressing the gas no floor mat or items in the way of the pedals. I pressed on the break (with the engine still accelerating) put the car into neutral and pulled over. Turned the engine off and restarted the car. The car ran fine after restarted it. No check engine light was on at any point just the wrench light. The light did go off after I restarted the car. I drove it about another 40 miles since this has happened and has not recurred since. I did have the car taken in to check the codes at about 90k miles (without the wrench light because it goes off as soon as you restart the car) nothing came up for codes.

Check engine light went on and when diagnosed it was one of the oxygen sensors. It had to be replaced in order for the rest of the safeties to operate properly. It was a defective part that cost over $400 to replace. Warranty was declined, however, the design life of the part must be in excess of 150000 miles. If this part were failing all the time, there would be a recall. My defective part was not replaced by Ford as it should have been. There are no moving parts, it should not wear out.

The contact owns a 2009 Ford Flex. The contact stated that while driving 40 mph, smoke was seen coming from the air vents. The vehicle was then pulled over and then driven slowly back to the contact's residence. The contact stated that prior to the failure, the vehicle was taken to an authorized dealer for a service done due to the check engine light illuminating. The vehicle was not diagnosed or repaired. The failure and the current mileage was 88,000.

Vehicle running sluggish approx. 3 weeks prior. Check engine light warning came on and immediately took vehicle to Ford for a diagnostics check. Vehicle had a code p0422, test ran verified evaporative system leak. I was told it was a safety issue and not drivable. Fuel filler pipe was cracked and needed replacement. Ford has prior recalls for this part over the years, although Ford did not cover this repair. 1 week prior one of two engine fans went out requiring replacement.

I purchased my Flex new on oct 2009 and it has shut off while driving three times since I bought it. The first time it happened I was driving through my neighborhood (with my children in the car with me) at 20mph all the warning lights came on my engine shut off, loss of power steering, loss of brakes. Luckily I was able coast to the side of the street. I waited a few minutes and it wouldnt start. I tried to start it again and it started up. The second time I was driving on the highway(with my children in the car with me) at 55mph engine shut off, loss of power steering, loss of brakes and check engine light came on, I coasted to the shoulder, waited a few minutes and it started right up. I took it to the dealership; they told me they couldn't find any issues that would cause the vehicle to turn off while driving so they didnt attempt to fix it. The third time was last week while driving through my neighborhhod(with my children in the car with me) at 20 mph, engine shut off, loss of power steering, loss of brakes and check engine light came on. I took it to the dealership again and again they told me that they couldnt duplicate the issue so they didnt attempt to fix it. My children were in the car with me all three times. I've taken to the dealership 3 times for this issue and they cant duplicate the issue so they can't find the problem so they didnt even attempt to fix it. I just dropped it off this week for the fourth time. Its very frustrating to have this issue especially since im scared to drive the vehicle with my kids in the car. I feel its a huge safety issue. Its a total inconvenience to have to keep going back to the dealership and drop off my vehicle. I have three children and need a dependable vehicle. Luckily we werent injured but im worried that the next time it happens an injury could occur. Why hasnt Ford listed this issue in their TSB!.
