2007 Chevrolet Impala: stuck in gear or won't shift

Filed Sep 16, 2023 · Electrical, Engine · PA

I started for the first time in early June of having reduced engine power. At this time I get several warrning lights on dashboard. I get engine power is reduced, traction control and engine light. The car goes into limp mode. I replaced the accelerator pedal position sensor after the first event. Since this time I had it happen 4 more times. This situation can be dangerous if a car is behind me and I slow up real quick due to going into limp mode. I try to pull over where I can when this happens. Once I pull over for 10 minutes the car will resume like normal driving with just the engine light on. The next day the engine light usually leaves. It is hard to know when this will occur but it can be a dangerous situation to be in.

The shift gear has become stuck in park twice. The shifter will not move. I had to have it towed to the mechanic twice in order for the vehicle to become operable again. The shop replaced some wiring and mechanics inside the shift area. Since they have replaced it twice, along with the original parts, I am on the third round.

On december 24, 2009, after parking my 30 month old 2007 chevrolet impala ltz on level ground at 6:30am in the morning and minus 13 degrees fahrenheit, I attended my morning workout for 1 hour. On return and after successfully starting the car I found the stick shift access button could not be pushed, despite following the recommended procedures, and the car was stuck in park. It was towed to the local gm dealer for $100. After six days and $150 in expenses for another car the gm dealer reported that the problem was a "broken ground wire" in the "shift lock solenoid connector" [inside the centre console where the shift lever is located]. The cost of repair was $137. My internet research shows this problem occurs often in chevrolet impalas, which suggests that the problem is in the design and manufacture of the vehicle. This problem could be life threatening if the problem occurs in a remote area at this temperature. I thought this was a power train problem since the part allows the transmission to engage, and therefore should be covered under warranty. Gm claims it is not part of the power train. My complaint is that the problem could be life threatening, is a defect in design and manufacture, and that the problem is a power train problem and therefore should be covered under warranty.

Parking brake will not hold in reverse. Dealership and gm states this is "normal." does not even hold on a slight incline, and on some drive ways the car gets stuck in park because of this. Known as "torque lock", the car will not disengage from gear because of load on transmission. I have to have someone rock the car back and fourth to disengage transmission. Fear the transmission is experiencing excess stress and may not hold causing accident or injury to unsuspecting people behind the vehicle.
