1 Vehicle Speed Control problem

Failure Date: 05/14/2021

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!.

3 Vehicle Speed Control problem

Failure Date: 10/26/2018

My Ford Flex 2009 turns on then when I go pout the car on reverse it pulls my car and makes a loud sound then I put it to drive and it does the same when I go to press the gas pedal it does not go at all. The ac turns on but it does not accelerate and the airbags light starts to turn on and off this is now . But a month ago it was drivable and when I was driving in the freeway going 70 miles the airbag lights would turn in and off then the tire pressure sensor fault turned on then the miles o was going when clear nothing on the dashboard would mark and the car was still going but wouldn't wanna go faster and if I break it wouldn't accelerate more.

4 Vehicle Speed Control problem

Failure Date: 09/08/2015

My Flex started having a hard jerk and bang when going from reverse to park. Was not always but frequent. The car started to run hot when sitting in a drive thru or traffic but would go right back down when I started moving. I took it into s mechanic and he replaced the fan. After replacing the fan the car began to have a really bad grinding noise when idling or traveling. Do bad I did not want to drive it. I took it into the Ford dealership and after 2 days they call and say they can't find anything wrong. Within 4 minutes I get another call daying I need a new transmission. The car would eccellerate on its own, shut off intermittently, and car would lag between 3rd and 4th gears. Ford dealership advised me to have a knew transmission put in. Car will shift properly most of the time even on highway. Only get whining noise at low speeds. I was also in an accident causing $13000. 00 worth of damage to front end and airbags did not deploy after hitting a car doing 35 mph.

5 Vehicle Speed Control problem

Failure Date: 03/24/2014

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.
