The contact owns a 2008 Chevrolet Impala. The contact stated that while exiting a parking lot, the vehicle suddenly stalled without warning. The starter disabled, service throttle and engine power low warning messages displayed on the instrument panel after the failure.

The failure mileage was 115,000.

Ignition failure and associated power loss occurred while driving on a crowded expressway after hitting a bump in the left lane. A very heavy key chain was in the ignition at the time. With no signals, flashers, or power steering, using only rapidly fading inertia for power, I had to make my way over to the right lane and on to the shoulder through thick, unyielding 70 mph traffic. Terrifying; collision narrowly missed.

Every time I would drive the 08 Chevy Impala the key would not turn all the way out. It did that for about a week. Then when I made it to work it did the same thing. Came out to go home it would not start at all the key wouldn't turn over. So we had to put it in manual mode to drive it to a shop. A wire in the handle to change gears broke because I was told the wire was to short. Now this was 42 or 43 thousand miles now at 82 its doing the same thing again. Why no recall?

While driving I noticed rear window was still covered with ice, the rear defroster was not working although the switch was on and light was illuminated, after that I searched internet sites and found that a connector on the passenger side has commonly burnt up so I checked mine and sure enough it is, another guy at work has the same thing on his Impala, currently car is at dealer being insp but they have said so far they won't cover repair, this is a fire hazard inside the passenger compartment of the car.

Whenever it is raining or I drive through a puddle of water on the ground, the steering wheel locks up for about 10-15 seconds and the car seems to lose power. I've concluded that this must be some sort of serpentine belt issue as a lot of components are affected at once such as alternator, power steering etc. This is extremely dangerous in my opinion as onset is unpredictable especially in hazardous conditions such as raining and for this reason I dread driving my car when it rains. Please someone acknowledge this as a legitimate concern!!!

Door lock problems: First the driver door failed to work. Then the right passenger door..(which has to be manually opened and closed). Now the driver side passenger door lock is undependable. The problem is becoming a hazard to driving the automobile in that the safety of the ingress and egress of the passengers cannot be guaranteed and this can become a definite hazard, especially in times of an accident.

The power door locks work interrmittenly, both with the remote key fob and the interior door lock buttons often resulting in manually having to use the key to enter the vehicle or physically pulling up the lock once inside the car to unlock a particular door. This is not a battery issue for the remote as I've even noticed on several occasions when using the remote to unlock the driver's door, the door lock register the "input" and attempt to move up to the unlock position, physically look as if something were preventing it from doing so, and remain in the locked position. And, its completely random as for which door lock will operate and there are stretches of days when all locks will operate properly with both the remote and the door lock buttons. Also, there is no pattern to which doors will operate as to front/rear, driver/passenger side and/or one, two, three, four, or zero doors locking/unlocking. This situation is extremely inconvenient (particularly when raining), potentially unsafe, and problematic in keeping your vehicle and its contents secure.

Rear window defrost stopped working. Replaced fuses and relay. Light comes on but defrost does not work. Investigation by owner showed wiring harness under front passenger kick panel burnt badly. Further investigation online indicates this has problem has been experienced by a large number of Impala owners. Due to the badly burn connection, passenger cabin fire could have occurred. Local Chevy dealer service department denied any knowledge of similar instances. Recommend investigation.

Impala 6-cyl

  • 150,000 miles
Both rear and the passenger door locks have stopped functioning with either fob key control or driver/passenger door controls. Totaling three door lock failures in two years. This is a large safety hazard to small children in the back of the car as there is no fast or easy way to open the rear doors once locked to get the child out in an emergency. I request this be looked into further for a recall as it creates a safety hazard especially for children in car seat on the back seat, which there is no quick way to unlock the doors to remove them in an emergency. Mechanic states: This is a known issue with 2008 and 2009 Chevy Impala vehicles. These model years were produced with a type of grease that bleeds into the latch actuator. After time the carbon from the motor brushes builds up around the actuator motor and shorts the communicator. Resulting in no power lock or unlock function. Requiring full lock replacement totaling over $1,500.

Every time it rains, or even if the air has been damp overnight, my front in-door speakers fail. The front passenger side, in-door speaker is completely burnt out and the front passenger side door lock actuator has also failed. I called the local dealership who wants to charge me to repair this. There is water leaking into the doors causing electrical failures to occur. Once the inside of the doors dry, then the driver's side front door speaker begins to work again. The passenger side front door is completely dead but the window works.
