I was told from a mechanic the car has either PCM or ECM problems. The car starts to die out when I'm driving it then I have to turn it off then restart it. It jerks really hard when driving it. The oil pressure low stop engine message comes on. It just has a lot of electrical problems and the mechanic told me the other Impala like mine are having either all the same problems or some of the same problems. Recall

My car stopped on 630. It said disabled full throttle. I had to sit for 15 minutes before it would start. I then hear a clicking noise that started at 830am and stopped at 832am. I've had nothing but problems with this car. Do not buy any Impala, unless you have a lifetime of fixable recalls. It's hot in Arkansas and to stall for 15 minutes with children in the car is unacceptable. When you call Chevy customer service, they can not help you with anything. They just take your VIN number and state oh I don't see a recall for your vehicle, although you read 5598 problems/same issue you are having with your car. Erratic transmission is the whole problem. So to Chevrolet and company please think about families and children when attempting to sale a new car with used products. It's not cool and the sad part is you will not fix it. Warrant my behind Chevy need a lifetime of recalls for everyone on all cars. May jesus be with your company. Sincerely a mother of 3 boys.

Two different outcomes but stem from the same issue. While trying to start my vehicle I get a click and care won't start at all. Sometimes after several tries it does fire up. Also when it does start it will sometimes stall. Most recently while traveling didn't the interstate it stalled going 75mph leaving me to coast and disrupt 4 lanes of traffic.

Rear passenger door locks do not function electrically when the vehicle is warm. Automatic lock function when the vehicle is placed in 'drive' does not function under these circumstances. Due to the position of the manual lock releases, it is very difficult to manually unlock the rear doors manually. In an emergency situation, if the rear door locks do not function, it can delay escape from the vehicle.

I was left sitting on the side of the road. I was going 70 mph on I-94 when the "service traction control" light came on, followed by the "engine power reduced" light, then something about "disabling throttle" sensor... my car shut completely down, leaving me to coast across 4 lanes of traffic on interstate 94. I've owned this 2008 Impala for just about a year... I don't know what to do I received the letter about an extended recall back in December and I called GM because there's a stipulation of the amount of miles you can have on your car to have this problem repaired... because my car has 276000 miles GM told me there is nothing they can do, at that time I asked why this item wasn't recalled. I was told if I felt the problem called for a recall I should reach out to the national highway and safety commission. I don't even feel comfortable driving my car anymore... this is a death trap!

The air conditioning actuators goes bad to a point where a knocking noise will start to come from inside the dashboard. This eventually will kill the electrical system and cause the car to cut off completely, even while driving.

This vehicle has been recalled due to air bags, and in a year no one has been able to get the repairs done to the vehicle. But furthermore the car has several other mechanical issues that I am showing as a trend with Impala being that my sister and cousin have one also in different years, the car makes a ticking noise when the air or heat is turned on the passenger side delivers opposite temp as the driver so if air is on the passenger will deliver heat and vice versa. If the car goes over a speed bump the engine reduces power and service stabilitrak appears across the lighting as well as the car dropping out of gear if I go over any bump. This is very dangerous especially being that my children and I were in this car and it decided to do this on the interstate at night in 70 mph traffic. After doing research on the vehicle I am showing that I am not the only person with all of these problems listed, and it bothers me that none of these issues have been recalled just as the air bags were even though I think the recall, is just to save face because no one is actually doing the work to get them fixed. At first I thought these things were just mechanical problems with age of car but after research these are issues that are in cars made in this time frame and warrants a recall for the safety of consumers.

Heater fails to deliver any air to driver side and only minimal amount of air to rider side when cab heater is in floor distribution mode or dual mode. Dealer advises this is by design and there is no problem. This is a ridiculous explanation and is a problem. Car has approximately 55,000 miles.

Issue occurred twice so far. Service traction control error message appeared followed by reduced engine power. 1st time this occurred the car came to a complete stop and would not run. Was on a small side street and only doing about 15 mph. I let the car sit after calling for a ride. Car restarted and drove to dealer 2 miles away. 2nd time same set of error messages, car was doing 70 on the highway at the time and dropped to below 50 mph. Drove to dealer. Both times, repair was identified as being a defective acclerator pedal position sensor. 2nd time vehicle had 92149 miles on it. Do not have the record for the mileage for the 1st time but it was about 1 year prior with estimated mileage of 77000.

Door locks will not lock or unlock. Door locks have quit working one by one. Front driver door only door with key lockable unlockable feature. Therefore, doors can only be unlocked by unlocking driver door and crawling into car and manually unlocking all other doors. I have owned no other car that had this feature where out in less than seven years. This is a safety hazard not being able to unlock/lock doors. The locks don't work whether car stationary or in motion.
