My Flex has repeatedly lost power while driving. I can feel the car lose power, and the yellow wrench light comes on. After reading up on it, I learned that you have to turn the vehicle off, wherever you are, and restart it after a few minutes. The wrench light turns off, and the car runs as normal, with no records of codes. This is talked about over and over in online forums. The safety issue is that it has happened on the freeway several times while traveling at a high rate of speed. The car loses power, and you cannot accelerate. You have to find a way to stop immediately, put the car in park (and listen to the transmission clunk) and turn it off. This last instance put me in harms way on the freeway. The car lost power while traveling 70mph. I immediately lost speed and had to cross 3 lanes of traffic to pull over to turn the car off. All of the forums talk about the throttle body, but everyone says that’s not the issue. The oss and tss sensors are also discussed. The dealerships cannot find out what’s wrong because once the car is turned off and restarted, any codes are erased. The issue persists, and the car keeps losing power wherever and whenever. I am referencing the most recent incident on this form, however, this has happened at least 12 times since September, 2020. Please, please force a recall on this issue!.
Tl-the contact owns a 2009 Ford Flex. The contact stated that while the key is in the ignition the antilock indicator warning light illuminated. The contact try to start the vehicle which failed to start. The vehicle was towed by the contact insurance company all-state to a independent mechanic where it was diagnoses but was unable to determined the failure. However, stated that the secure lock system would need to be reprogram by the dealer. No dealer was contacted. The vehicle was not repaired. The failure recurred. The manufacturer was made aware of the failure and transferred the contact to NHTSA to place a complaint about the failure. The failure mileage was approxmently 169,000. Ck.
As I am driving come to a stop. Proceed in motion making a left turn or right turn vehicle will lock up slowing down with grinding. Now this has happened 3 times on the road causing traffic to stop.
This in reference to the transmission, I have had it looked at and no one can seem to narrow down the exact problem. The vehicle stalls while driving. After stopping and restarting the vehicle it hesitates and the kicks into gear and drives. This doesn't happen every day, but not knowing when the vehicle might stall is troublesome. There is TSB 11-12-10 that describes this problem, the Ford dealerships do not have any safety recalls in reference to this.
Part of my power in my car shut off on the freeway, at 1:39 pm at 67 degrees outside . I had been driving for 40 minutes. My dashboard went dark, and only my clock time was on. I glided to the side of the road, and was able to pull the car very hard to the right (as the power steering was off). Then turned the key to off, waited 3 minutes turned the key and it went back on. It has not happened again.
Transmission shifts very rough. While in motion.
Transmission. When the temperature is 40 degrees or below I sometimes have an automatic transmission problem. In the morning after the vehicle was parked over night I start the vehicle, put it into reverse, I back 40 feet down my driveway which has about a 30 degree grade down to the street. . I stop on the street, put it into drive and turn to the right to proceed forward up the street with about 10 degree grade for about 300 feet, then the street has about a 15 degree grade for the next 200 feet after which it has a 5 degree grade for 75 feet at which point there is a stop sign at a busy two lane cross street that is fairly level and has a 35 mph speed limit. I stop until the traffic gives me a 100 to 150 feet more break between passing vehicles so I can turn right, many times the engine revs to 4000 rpms but the vehicle accelerates vary slowly at picking up speed. I often travel 600 to 100 feet before I attain 25 mph. Then it shifts into the correct gear. I have had it to the dealer 3 years ago but the Ford dealer charged to test it but found no problems. Four months later I took it to aamco who found a problem and repaired it, "they thought" replacing some parts. The same problem persists after the "repair". The excuse is that the car is warmed or the conditions cannot be reproduced. The Ford dealer said that they cannot come 8 miles to my home in the morning to reproduce the conditions. The transmission fluid level has always been declared to be ok.
The power transfer unit (ptu) fails on a number of Ford models. The seal leaks and in my case the unit needed to be replace because of metal shavings. The cost for repairs $2,600.
Car started 2 years ago with "stuttering" when driving between 50-60 mph, as if the car couldn't determine which gear to stay in. Had transmission flushed and refilled in April 2016. Problem was less but still remained. Added dr shutter in June 2016 to the transmission fluid and problem has went away, that was last year. Paint on the hood is peeling and started out as a small chip may 2016, and is now the size of a 2 basketballs. Black body pieces that are between the windows on the side and in front by the windshield are loose and coming off. Will provide photos if needed.
My Flex started making a little grinding noise when only turning right at first. Now it sounds really bad turning either way. And it shakes when accelerating.
Vehicle stop running no power.
Engine stumbled and then lost power. It re-started but idled at 750rpm. Car would not accelerate. Placing the car into neutral and depressing the accelerator did not increase the engine speed. This persisted about 3-4 minutes. Afterwards, the engine speed responded to the accelerator, and when placed in gear, accelerated normally. This has happened three times in the past year.
Tl-the contact owns a 2009 Ford Flex. The contact stated whenever shifting into the reverse position the transmission would jerk violently. The vehicle was taken to an authorized dealer six times for the identical failure. The technician detected a trouble code and an unknown repair was performed on the transmission. The malfunction recurred after the repair. The vehicle was currently being repaired. The manufacturer was notified of the defect. The approximate failure mileage was 80,000. The VIN was unavailable. Js.
1) driving at steady speed. 2) let up on gas pedal and car did not slow down. Occurred twice in three times that vehicle was borrowed from a friend; one time with a witness. 3) pulled my foot completely off floor and applied brake; problem (in my opinion) is poor pedal orientation which leads one to believe that gas pedal is no longer pushed when one just lets up on pressure on gas pedal, along with too lite of pedal return pressure. Have been told Ford is aware of this but feels it only happens if someone is wearing big and heavy work boots. My incidents happened with running shoes. . . And I only wear a size 10.
