“On the way to work, the check engine light went on. After a few miles, at an intersection, my car jerked and I didn't have enough time to make the signal light. I decided to go back. After I shifted to reverse, the car didn't move back and stopped there totally. I had to turn off the engine and restarted, the car worked. I took the car to the dealer right away, it needs entire valve body/conductor plate assy-replace and retest and total cost is $2000.”

“I was driving on the highway and could hear that the engine didn't sound right, it was revving at a higher RPM than normal. I pulled over to see what was wrong and it continued to do this every time I tried to accelerate. I turned the car off, turned it back on and then only had 3rd. Gear available. Nothing else. I later found out that it's called limp mode it wouldn't go faster than 40mph and nothing else worked, just 3rd. Gear and reverse. After doing extensive research I learned this is a problem with most 7-speeds and the amount of people having or had this issue is appalling. …”
