In motion on highway with cruise control car dashboard shows 'stop safely now' loose acceleration. Turn car off then back on and can drive. Check engine light on. Told vacuum pump creating issue. Replaced and car okay. While in motion on highway during acceleration 'stop safely now' entire car shuts down while driving. Loss of brakes, steering, acceleration. Get car towed back to shop and told acid leak degraded wire harness. But also told they can't ensure the car will be fixed from repairing. How does a battery leak so bad without any cracks. No shop can confirm the acid leak is causing the brake issue. Possible ABS module, electronic control, o2 sensor replacement too.

Takata recall I was driving and the car began to slow down rapidly. I was unable to control where I was going and unable to accelerate or decelerate. I have no control over the vehicle when this happens. It is not an all the time problem, but does happen very often. The check engine light comes on when it happens and the car accelerates briefly before instantly shutting off. The wrench symbol also comes on before this all takes place. I could be using cruise control or just normal driving and it happens in both situations. The vehicle tends to do it no matter where you are such as a high way or on a regular city street. I have had the vehicle checked out numerous (six) times to see why it does this. The mechanic hooks it up to the computer every time and states there is nothing wrong but then resets the symbol lights so they go out. The car will be fine for a week or so and then do it again! It is scary when it happens and I try not to drive the car due to this issue. How can you fix something the mechanics state is not broken? Something isnt right with the vehicle and something needs to be investigated to see why it does this! It can not only be my car!

While driving at highway speed with cruise control engaged, the cruise control de-activates, the check engine light comes on, and the wrench icon comes on at the instrument panel. The engine begins to run very rough, surging, then slowing down, and the cruise control cannot be re-engaged. The throttle body was replaced by the ford dealer 18 months ago, and the condition that exists now was the same that existed prior to the throttle body being replaced 18 months ago. Vehicle currently has less than 68,000 miles. Fuel economy is 20% lower than normal. It is frightening to attempt to pass on 2-lane roads, because you never know when the engine will sputter. This started occurring occasionally in mid-june, 2017, and now occurs every time you drive the car. Code that was stored was p2119, "throttle body range."

I was driving for about an hour down the freeway in cruise control. The car jerked slightly and went limp, decelerating while maintaining a rough idle around 1000 RPM's. The gas pedal was non-responsive while idling and I was able to coast off to the side of the road where there was no throttle response. The wrench light was on the dash. I turned the car off and tried to start it again, it started fine and I was able to drive it the rest of the way home without further incident. I have been afraid to drive anymore on the freeway since or any serious length knowing there is a serious issue with the vehicle. This is a terrible feeling knowing I have a fairly new car that I cannot trust to drive safely in. I have read others stories about this problem and seriously hope the vehicle's issues do not cause me to be involved in any accident on the freeway at high speeds. There is obviously an issue with a serious flaw and needs to be addressed.

Tl* the contact owns a 2010 ford fusion. The contact stated while driving approximately 70 MPH using the cruise control, the vehicle stalled as the wrench warning light and the brake light illuminated. The vehicle was merged to the side of the road where it was restarted. The failure recurred multiple times. The vehicle was taken to an independent mechanic. The technician diagnosed that the electronic throttle body needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 69,000.

I was driving on the interstate at approx. 55 MPH, with cruise control activated. The vehicle suddenly deactivated t he cruise control and started slowing down. Wrench light came on, and it stopped responding to pressing of the accelerator. I steered the vehicle off the interstate and on to an exit ramp, with brakes and steering unaffected. When I put it in park, the engine was sputtering and the car shaking. After shutting off the engine and restarting, the vehicle ran normally without warning lights. Repair shop employees said it was probably the throttle body, but because the car computer had not recorded the codes, they weren't sure.

We had been driving for 175 miles on the highway with the cruise control set. The car suddenly lost power with no warning and started slowing down. The service engine light came on as did the symbol of a wrench. I pulled off to shoulder. The car was idling very rough. Stepping on the gas did not raise the engine speed. I shut the engine off and looked under the hood. There was nothing obviously wrong. I tried to restart the engine. It started and ran just fine. The warning lights were off. About 16 miles later the same thing happened. There was a small ford dealer a few miles away so I took it in. The person I spoke with was aware of this issue and indicated there was a service bulletin about it. Apparently the problem is with the throttle body. They did not have one available. He said the car should always restart and we should be able to make it home. We drove the next 300 miles wondering what would happen. The car was fine for the rest of the trip. When we got home I looked this up on the internet and found countless postings of the same issue. It is obviously well known. Given this, I think there should be a recall. This is very dangerous. We were on vacation (myself, wife, children) on a rural highway when the engine failed the first time. A semi truck was behind us and started catching up fast as I drifted off to the shoulder. They were blowing the air horn at me because there was another truck coming the other way and he could not move over.

I bought my 2010 ford fusion sel v6 with 12000 miles and drive it daily 120 miles/day to work. It has 106,000 miles now. Last week, for the third time, the "service power steering now" and "service advancetrac" indicators flashed on while driving 70 MPH at night, using cruise control. Arrived home safely, next morning, no power steering. Drove car to ford dealership, who hooked it up to diagnostic machine, and cleared messages, power steering now functioning again. The second time this occurred the dealership looked at something to do with the wheel on the passenger side. I have not used cruise control with this car since the second episode, nearly a year ago. Last week, when the third failure occurred, my friend was driving the car and had activated the cruise control, and I had warned him that I believed there was some relationship factor with using cruise control and the loss of power steering. I drive quite roughly, aggressively, and have hit many bumps with no loss of power steering. During the first and second occurrence the cruise control was activated, a rough spot was encountered, and the "service power steering now -advancetrac" messages came on, with consequential loss of power steering. No mechanical work seems to matter, only effective action is clearing the messages and reestablishing power steering by hooking up to diagnostic machine. I believe it is a software glitch maybe involving a sensor. I am not a mechanic. Will the recall/replacement of throttle assembly solve this problem?? Ford needs to step up and respond to this problem.

Traveling on I-10 near beaumont tx, with cruise control on when the car suddenly lost power/speed. I pulled off the freeway, tachometer jumping and with brakes and steering working. I could not get idle to steady, wrench light on; so I shut down engine. Restarted was slow but I was able to continue normal driving. Next morning took it to kinsel ford dealer, they checked it out friday and found no issues. Yesterday may 3rd it happened again. Knowing the posted throttle body issues, kinsel should not have sent me on a 7 hour trip back to dallas!!! This almost got me killed.

Driving highway speed with the cruise control active, on my way to work. Turned off the cruise and the car "bucked." the wrench warning light came on. It would lose RPM and then go back up again. Turned around and went home. I didn't want to be stranded at 4:30 in the morning. Got home, turned the car off, and restarted, and the light was off. Took it to the ford dealer and they said it's the throttle body. But...my car for some reason isn't covered under the extended warranty. I have a 6 speed manual. It uses the same throttle body as automatic transmission cars. What gives??

Driving down the road, my car looses power, the gas petal has no effect on the engine. I press the petal and it has no response, no RPM response. Each time I must pull over, put the car in park and shut the car off (reboot). It appears to be a throttle body issue - it continues to take place at variable speeds and with and without cruise control turned on. It's taken place several times on the interstate, causing me to cross 2 lanes of traffic to "reboot" my car. It's taken place for rthe past 10k miles - getting more frequent each week.
