- I have experienced a sudden loss of engine power and speed on 5 occasions. Very scary and dangerous to completely lose power on the highway with cars behind you. Had to pull off onto the shoulder(s) in dangerous conditions, with two young kids in the backseat. Hazards, turn off the car, restart the car, etc. - when the power loss happens, the vehicle's dashboard lights turn on, including the engine and wrench icons along with the words "see manual. " - based on my research, I believe it may be due to a defective throttle body and/or software, related to the "terrain management system. " - problem was not reproduced or confirmed by a dealer or independent service center - no inspections by the manufacturer, police, insurance representatives or others - no warning message is provided prior to the failure, which is another issue.
On September 27th 2023 I brought my vehicle in because it was having shifting and vibration issues. To shop notice that the information I gave them was related to the transmission and with further review there was a recall on the transmission part of me coming into the shop. Which I wasn't aware of even when I brought my vehicle in months before that for recall maintenance. I had to pay for my transmission to be repaired we should have been done by Ford. The car was driving fine until early this year when it starts to do the vibration that was the issue previous when my transmission was going out. So I set up appointment at Ford dealership while I was in route to the dealership my car started to sputter and shake and fall out of gear. So I turned around tried to make it home in the car just stopped moving. I wasn't able to move forward or reverse there is no connection within the transmission for my car to move. I got my car towed to the dealership who diagnosed my car and my transmission and they stated that there was metal fragments found in the fluid level and I also said that the torque converter clutch performance never engage when it was testing it. I told him about my previous transmission issue with Ford and I also states them that four has have many federal recalls dealing with their transmissions in their vehicle.
Since the car was new I experienced occasional situations where the car would not accelerate. I thought it might be the transmission slipping as it seemed to "bottom out" when hitting the gas. The car would not respond and I would coast onto the side of road for fear of getting hit. After a minute or so, the gas pedal would work and I could keep moving. I reported it to the dealer and at that time it was winter and the roads were icy so they were not able to test it. Nothing showed up on diagnostics. It has been happening more frequently (twice since June 2022). Upon further research it seemed to be the throttle body so this week I took it to the Ford dealer where I purchased the car and told them what was happening. They confirmed that it is a bad throttle body. They are now replacing it at a cost of $781. I have found numerous sites on the internet that this is a well-known problem and in some cases it seems that Ford issued an extended warranty on defective throttle body assemblies and sensors for 10 years or 150,000 miles from the original purchase date. So why does this not apply to me? this is very dangerous and I was lucky to not get hit. When the car stops accelerating in the middle of traffic, it would be easy to get rear ended or worse.
When driving the car I corrected to move further to the left on the road. In doing so it felt like I ran over something and all of a sudden the car accelerated (initially I was driving around 20-25 mph) and I struck a tree. I sustained a t spine fracture and was hospitalized for 5 days. I just have a case number with Ford but they seem disinterested. When the car accelerated I felt it was going a 2x the speed.
While traveling with adaptive cruise engaged we were in left lane following a semi approximately 1000� ahead of us and when he moved over to make an exit our vehicle passed by and auto braked hard causing vehicles behind us to take evasive action from hitting us along with vehicles in the right lane of traffic. This also happened again the following week except passing by a dump truck. I was aware that time an mashed accelerator in time as instructed as per operating manual. I don't feel safe using my cruise with or without adaptive on and now several weeks later I'm getting an �adaptive cruise not available� message displayed on instrument panel.
I have been experiencing acceleration/transmission concerns, where the vehicle essential stalls and will not accelerate. After approximately 5 seconds, the computer and transmission appear to �sync� and the vehicle will accelerate, but the issue will continue to happen until the vehicle is turned off and back on again. The first time this happen, I was in a costco parking lot, so I did not think much of it. The second time this happen, July 12th, 2020, I was crossing a busy road of traffic near my home and was almost involved in a serious accident as a result of this failure. As I was crossing the 2 lanes of traffic to make a left hand turn, my vehicle stalled and I was almost side swiped by an oncoming vehicle. After this incident, I had my vehicle towed to a Ford dealership for inspection. Upon extensive analysis of the vehicle, the technicians could not find anything wrong with the vehicle including no failed sensors in the computer and the technicians were not able to replicate the concern. On August 19th, 2020, my check engine light came on and I immediately returned the vehicle to Ford dealership hoping this was a result of the issues I had been having. Upon another diagnosis, the error was cleared for an engine knock sensor, but this was not related to my concerns with the acceleration or transmission.
After 4,000 revolution the SUV comes to stop the engine and run quickly again.
