While driving at highway speeds the car will act up and the engine will shut off, I get the message on the odometer display that reads, Engine power is reduced, service throttle, starter disabled. This is not a good thing to have happen while driving.

Heating and air conditioning actuators and/or blen door getting stuck so the air will not switch from cold to hot or hot to cold without pulling the glove box out and manually turning them by hand. Heater will blow hot air and then randomly switch to cold air. When it's cold outside, I cannot defrost my windows cause it gets stuck on cold air which impairs visibility.

While wife was driving at normal speed car went into limp mode many times over last few months causing accelerator pedal sensor codes.we have since changed this pedal sensor 6 times and same issue and codes pop up. We also changed throttle body w sensor and connector pigtail.I think there is corrosion in ECM and all these items have failed. These items should have been recalled as manufacturer defects in my opinion.we are still having problems same codes and im not the only one!

When first purchased I had to change accelerator pedal. When I took it to the shop I was told they get a lot of people w Impala same as my year 2008 that needed to have the accelerator pedal changed every so often because they would go out and it would cause the check engine light to go on and off because the vehicle was sending the wrong signals.I would drive on the highway and street it would cause reduced engine to come on and slow my car down almost leading into accidents because I did not know it was about to happen. It would come and go on as it wanted. The electrical part of the car is something in the car continues to drain my battery. I've gotten a new battery and it still drains causing me to have to get it recharged. The suspension I was also told for the year of my car is bad. When purchased I found out that again people that purchased these years of vehicles had problems with the control arms and that I now have to take it to get fixed because one hit to a pot hole can cause the under part of the car to break and cause a bad accident. I did not know Impala had this many problems. I seen the police Impala for 2008 were recalled for suspension, but they all seem to share this common problem as well as the actuator continuously clicking. It seems to be an easy fix, but I shouldn't have to fix something that is a common problem for the Impala.

Rear door locks, defrost, trunk lid stopped working. Noticed smoke on my passenger side while driving in town. I took it in and was shown that it melted the wires together and melted the rear body harness connector. ( I kept the part if needed) this is a danger to drivers. The fire can start at any time while driving! I believe this should be a recall. After researching I see this is happening to many of these cars.

The contact called on behalf of the owner of a 2008 Chevrolet Impala. On several occasions, the vehicle failed to start and the reduced power warning indicator illuminated. Additionally, while driving 55 mph, the vehicle stalled. The contact was unable to restart the vehicle. The contact stated that the failure was intermittent. The vehicle was diagnosed by an independent mechanic and fault code: P-2135 was retrieved. The mechanic replaced the ECM, throttle body, accelerator pedal mechanism, and the wiring harness between the ECM and throttle body; however, the failure recurred. The dealer and manufacturer were not contacted. The approximate failure mileage was 80,000.
