The transmission go out at any time while you're driving it'll just stopped in the middle of traffic which can cause an accident the company Chevrolet new that they put bad transmission in those cars and lights blink on and off. Electrical issue the speedometer and the gas meter in moves by itself when the car is off and when you are driving the car it'll move by itself displaying accurate information and that's very dangerous I was on the highway in the transmission just went out in cars almost ran into me I like to buy that day because of the transmission everybody I know with this car has the same issue something really needs to be done about it before someone dies

My Chevy Impala when in motion has signals for service stabilitrac, the check engine comes on and the a message that says reduced engine power shows up. It seems like alot of Impala owners are experiencing this and something should be done! the stabilitack goes off and the check engine ligts stays on but usually goes off, and then a few days later it will happen again.

Driving home one night after just having my vehicle repaired a few weeks earlier, without warning, my vehicle began to stall. Just before the stall it was driving completely normal with no issues at all. Suddenly the check engine light came on along with the messages of service stabiltrack, traction control disabled, and low engine power. When I took the vehicle to the dealer I bought it from I was told that there was an aftermarket senondary air check valve that was causing the issue. With this they gave me the following codes; P0068, P0340, P0651, and P2135. Due to me just recently getting this part replaced this past February I took it back to the mechanic that replaced it. When I received the vehicle back it would no longer even start. The mechanic then informed me that the air valve would not cause this issue and there was something else wrong with the vehicle and to take it to another dealer. When that was done I was told a second time that it was the air valve. I have now come out of pocket twice for tows that I can't afford. Along with paying for an expensive part possibly twice. Vehicle only has 50K miles on it and has never given me any issues until this year.

Driving 65mph on highway when "reduced engine power" and "service stabilitrak" lights came on and engine started to throttle down. Had no choice but to pull over onto left shoulder with a semi close behind. Turned car off for 1 minute and restarted and the "reduced engine power and "service stabilitrak disappeared. How is this not a safety issue requiring a recall?

- Lansing, IL, USA

I was traveling West bound on interstate 22 when the stabilitrak requires maintenance displayed across driver's information center. Next the traction control light and display lights up followed by, reduced engine power, in which I lost almost all power to my vehicle. I was traveling around 70 mph in the left lane and had to navigate two lanes of traffic to reach a safe spot on the shoulder of the interstate.

Major safety issue! while driving on the expressway hours from home reduced engine power/service traction control/check engine lights came on. Cruise control disabled as well. Car stopped on the expressway, steering wheel locked up. Luckily we were able to coast to the side otherwise this could have been a disaster! vehicle was towed to a nearby service station where it is currently located. There are several complaints out there like this. GM needs to recall and fix this problem!

2010 Chevrolet Impala. Consumer writes in regards to vehicle sudden acceleration caused by sticky throttle accidents before receiving accelerator pedal position pedal sensor and throttle position sensor recall notices. The consumer stated she was backing out of the driveway, when the vehicle took off like a missile. It traveled across the street, jumped a curb and hit a parked vehicle in the driveway causing damage to both vehicles. The dealer claimed there was nothing wrong with the accelerator. However, the accident was caused by a sticky throttle. When the second accident occurred, the consumer was attempting to back the vehicle up, but instead it accelerated backwards at a high rate of speed making a high pitch whining noise. The consumer quickly applied the brake. However, it not reduce the speed. The consumer hit an oak tree, and in doing so, caused the tree to fall on the vehicle. The vehicle was totaled. Between the first and second accident, the throttle was repaired and the accelerator was replaced.

Engine power dropped significantly on a two lane hwy. Traveling at 60 mph. Almost got rear ended and experienced road rage from driver behind me. Scary. I then noticed a service traction control warning, and engine speed reduction notice. Cruise control would not function. This warning will clear itself but continues to occur. I took it to my mechanic several times and they can not identify it even when the warning and condition is active. Veh. Mileage 126700.

As I was driving on a state route, alerts appeared for "service traction control" and then "service stabilitrak" followed by "engine power reduced". the engine light also came on. I pulled over and shut the car off, waiting a few minutes before restarting. The messages stopped, but the engine light was still on. I drove a few more miles and approached the on-ramp to the interstate. As I accelerated to merge onto the interstate, the same alerts came back on in addition to "starting disabled, service throttle". shortly thereafter, my car became completely disabled and shut down as I was on the interstate- the engine cut off, no power steering, no acceleration!! thankfully, I was able to safely pull off the side of the interstate. I had the vehicle towed and the car started right up and seems to run fine at the repair shop. Worried when and where it will happen again.
