My complaint concerns my 2007 Chevy Impala transmission floor shifter is locking in park.. I could not depress the button on the floor shifter, to shift to reverse. I tried turning the steering wheel which of course is locked when the vehicle is in park. I am worried that next time it will not get unstuck. So I checked the internet and saw many comments about 2007 Impala shifter's locking and realized I needed to file a complaint.

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.

- West Park, FL, USA

I was driving down the road suddenly check engine light came on speed reduced get a reduced power/traction control message and speed drop to 40 in matter of seconds engine running very rough. Almost caused a accident due to this happening at the morning rush hour on commute to work. I looked online this seems to be a common complaint that there needs to be something done about it. I have had other issues (eg: Steering mid-shaft failure front end shimmy, brake issues, connector to rear defrost melting, wires in shifting console breaking to where couldn't remove keys or get out of park) with this vehicle and called GM about them and they assign a case number and tell you sorry you will need to pay and keep receipt if there is ever a recall issued.

After driving it for many years and having no problems, I drove it a short distance and parked and could not remove the key, I tried taking it out of park and putting it back in park and after trying that several times and it not working I tried (jiggling the shifter when it was in park) and it released. It happened again for the 2nd day in a row. I will bring it to a local repair shop after the weekend is over and see if it is a bad wire or something.

The vehicle failed to shift into park. The vehicle was taken to the dealer where the technician diagnosed that there was a broken wire in the BTSI solenoid terminal which needed to be replaced. The vehicle was repaired by re wiring the ground wire to the shifter where the pin had broken. On May 3rd the key got stuck in the ignition and would not come out. Let the car sit for 24 hours the battery died and the key released out of the ignition. Took the car to the dealership on May 5, 2014 and the shifter wires were re constructed. Car still acts as if the shifter is not going to shift.

Started having trouble with my transmission a while back. If I was at a stop and tried to accelerate it was slowly take of then all of sudden slam into the right gear then take off. It also happened even if I didnt come to a complete stop and tried to go again. My check engine light came on after about a month of this happening. I had it checked. It was a shift solenoid. Since I was still under warranty I had it replaced. It was fine till about a two weeks ago 08/20/2013. Now my transmission is doing the same thing again.

After stopping, I push on the accelerator, the engine revs but the transmission does not engage, after two seconds the car will slam into gear and violently lurch forward. Powerful enough to strain my neck. Very dangerous.

2007 Impala ss. Transmission hesitation occurs when going around 45-60 mph. Car semi-engages shifting, but then backs out, giving a chugging sensation while driving in that speed range. Higher speeds above 60 produces an incredible screech/whine noise. Currently in shop for transmission diagnostics. At 74,000 miles clutch was replaced due to it being cracked in half. GM has either mad poor transmission engineering, using shotty parts, or this transmission is overly underrated for the power of the engine.

First, when I slow down to turn a corner, I take my foot off the gas. After the turn, when I press the gas I have no power. It doesn't die, it just won't go anywhere for about 15-20 seconds, no power. That doesn't sound like a long time unless you are sitting in the middle of a busy intersection. I have to come to a complete stop for about 20-30 seconds, then take off. Sometimes it goes, but feels like it jerks into gear. That's ok at stop signs but stop lights that turn green as I approach can be dangerous. Also, if I turn a corner onto another street, it hesitates. And sometimes I have almost been hit from behind. People expect you to turn and proceed. When you just stop, they may not. I also noticed one day, when I just coast on a level road, my car sometimes accelerates for quite a while, instead of slowing down immediately. I once took my foot off the gas at 45 mph and coasted on flat road for 2.5 miles. The latest related problem is.. spring 2013, twice, I turned a corner and it just died. I had to pull over to the side of the road to get out of traffic. After a few minutes, it cranked back up. Thankfully, I was on a city street and not a four lane road. I also have problems with parking. I put my foot on the brakes and pull into parking spot. When I put it in park, it lunges forward. Or if I stop in traffic, sometimes it lunges after it stops. I have to make sure that I leave plenty of room in front for this problem. I think it has something to do with the computer allowing the gas to flow or stop. I had the transmission rebuilt and it still does it.
