Car Stall problems of the 2012 Ford Flex

Bad throttle body. Stall when driving and jerky motion, both when going slow and when going highway speeds. Red wrench light comes on, pull to side of road shut off and turn back on and drives fine until the next time. I had it replaced w/ brand new part at a shop and it is still malfunctioning.

We have a 2012 Ford Flex normally aspirated engine. Starting in August, we had an issue with our electronic throttle body which caused our car to shut down. We had the part replaced, shortly after a similar problem occurred. This was due to the dealership frying the computer. This was replaced, by the dealership, after calling Ford directly. In February, the electronic throttle body failed again. Replaced under warranty. The same issue occurred last night and the vehicle will be taken back to the dealership. All signs point toward the electronic throttle body again. Every time this issue arises, the car goes into a safe mode while traveling down busy streets. This results in speeds of around 5 miles per hour and can cause major safety problems. The vehicle and the part installed are no longer considered safe to drive any distance greater than five miles from our residence, in case we need to get home. To clarify, the vehicle was in motion .

There are several different incidences that have occurred. (1) while turning a corner or slowing down the a/c will shut down. (2) the control panel instruments will go all the way over to the right and then surge forward when turning a corner. (3) car has died on several occasions especially while trying to accelerate onto highway. (4) a/c will turn on by itself and blow on maximum even when power switch is turned off. (5) when car loses power, all codes are reset so dealer is unable to get a clear reason why car is doing this. We had a black box installed for two weeks with some results pinpointed but after it was "fixed" we continue to have the same problems. Dealer connected a computer while we drove around block and the computer diagnosis was that we were pushing the brake and gas at same time. . . Not possible! the reading was that the brake had been touched more than 2000 times while driving 20 miles. We have had this car in repair shop 8 times and no resolution yet. Dealer said they would stand behind vehicle with an extended warranty at no cost while we tried to find problems but now warranty is up and they want us to pay for extended warranty. We were told by dealership that if we apply for lemon law that we would most likely lose the case and it would only cost us money. According to texas law. . . This car definitely qualifies~ we are waiting to hear from our attorney. I hope no one else buys this type of vehicle~.
