2009 Chevrolet Impala: engine overheating

Filed Jun 25, 2018 · 10,999 miles · OK

2009 chevy impala lt malfunctions 'blend door actuator not turning causing the temperature control system to not work properly: *the heater blows cold air when in park *there is a loud knocking sound coming from the dashboard. When I start my car, unlock my car, open a car door (driver, passenger, front, back) and while my car is parked with the ignition off. 'the front driver side door lock mechanism not working: *I have to manually lock and unlockthe drivers side door with the key and sometimes my kids have to unlock door from inside the car. 'left passenger power window won't roll down. The last two items could result in a short in the circuit board. A short may cause the power door lock and power window switches to become inoperative. These could cause overheating, which could melt components of the door module, producing odor, smoke, or a fire increasing the risk of personal injury. Mechanic said that these malfunctions are a common problem in chevy impalas so it seems that these are obviously faulty parts. I am extremely aggravated that this is a known and consistent issue with this car yet have not been recalled. Not good! There are several actuators, they all need to be replaced. Gm should do a recall on this model to fix these items. Could be significant if there's an emergency and I can't unlock the door and can't roll left passenger window down. The last two conditions could increase the risk of injury during a crash.

There appears to be many issues related to brakes and suspension for the chevy impala. After only 10k miles, the brakes began to pulsate. The dealership resurfaced them. They were fine for a bit longer but then the issue reoccured. I am not sure if its a overheating issue or what but it has had other brake and suspension issues as well. There is under 30k miles on the car and it has already had: left front tensioner replaced, rear left sway bar removed/reinstalled, rotors refinish, and a whole new set of tires now. We have had many other gm vehicles over the years from both chevy and buick. No other vehicle has given us as many issues in such a short period of ownership that this car has. It all appears to be related to the brakes and suspension. Based on online searches, we are not alone as many impala owners have had similar brake related issues/complaints.

Tl* the contact owns a 2009 chevrolet impala. The contact stated whenever you are driving down a hill the steering wheel began to shake violently and the brakes overheat. The vehicle was taken to the dealer who installed new rotors under the warranty but within two months the identical failure occurred. The vehicle was taken again to a mechanic who installed new brake pads and heat shields behind the rotors so they would not overheat but the failure recurred within a month. The manufacturer was not notified. The failure mileage was 25,000 and the current mileage was 35,000.

In june 2010 I was driving on the interstate 90 west toward denver co. The terrain was steep and winding and due to heavy traffic the pace was fast. The traffic ahead of me began slowing and I began to slow by steady light pressure on the brake pedal. My brakes heated up fast and I found myself without breaks for a short period of time due to the rotors feeling as though they were warped and the front end started vibrating. I down shifted to 3rd. Gear but that was not enough to slow me enough so I downshifted to 2nd and this still was not enough to maintain a downhill speed to keep from having to use the brakes. Finally I shifted to !st gear to maintain the safe speed that I needed. The problem seems to be that the car freewheels so excellent that even on lower grades as experienced in the carolinas in october when we were there the car is almost impossible to gear down so as not to overheat the brakes when trying to maintain posted speeds in mountainous country. I discussed this with solomon chevrolet in dothan where I get the car serviced and the dealer from whom I purchased the car. They had no suggestions but assured me there was nothing they could do dealership wise to help me. I feel it is a very dangerous situation which does not surface unless you drive in the mountains.
