What owners say
Reference tsb 11-10-21, the car will surge and try to move forward quickly when at low idle and slowly moving at times when the car is close to another car such as parking in a parking lot. If the driver isn't quick-reacting with the foot already on the brake pedal, the auto could move quickly and contact the nearby auto or structure before the brake is pressed stopping the vehicle from lurching/surging forward. There is a tsb issued, but it should be a safety recall due to the risk of contacting another nearly vehicle or structure. It has steadily grown more frequent over the past year.
The car has been lurching forward and decelerating randomly. Keeps going into "failsafe engine mode" and the wrench light comes on but only for a few moments, then runs normally again after restarting. Haven't been able to have the light on long enough to get diagnostics done. Happens while driving or when starting occasionally.
Car runs great for about 20 minutes then I get a surge in the engine, dash cluster goes dead, car jerks and I lose power randomly. Everything comes back on but will go out multiple times getting worse everytime. I have lost power to transmission once, no forward or reverse. Replaced the dash cluster and car ran great for 2 days then started all again. This happens mainly while in the city, hasn't happened on highway yet thank goodness. Car just sits in driveway, afraid to drive it. I see countless people with this issue all the way back to when car was released and still no solution.
My 2005 mercury montego shuts off while going down the road. I have paid around $4000 to try and have the problem fixed and it has never stopped. The reverse gear is unusable, as soon as you put it in reverse it shuts the car off. The transmission jerks and will not steadily accelerate at random times. The car will randomly shut off when going down the road losing all power steering and power braking ability. This is particularly a problem considering I have an infant in the backseat most every trip. I saw this lawsuit and every single thing listed about the CVT transmissions has happened and is still happening to my 2005 montego.

When braking it jerks and shifts into neutral and the engine reeves to 5000+ RPM. After braking and slowing it again shifts back into drive. This only happens when braking or increasing speed. No dash lights illuminate, indicating a problem. Having to slow suddenly in traffic is very dangerous. A ford dealer recommends a new transmission and a transmission shop recommends a new electronic module..this is an intermediate incident problem occurring approximately every two to four weeks. .
I just pulled my car off the lot not even 10 minutes later there was jerking then my car stopped dead in the middle of a busy street.this has happened numerous times with the worst being on a one way and my nieces no more than 10 years old in the car my car made a kind of a loud humming noise,jerked then stopped in the street.at times I can't even reverse or go up steep hills.
