2009 Chevrolet Impala Owner Complaints

For the last 2 years, the car willl come up saying airbag system issues. There airbag sensor under the passenger side seat will randomly throw a code for the erorr and then turn off. It does not have to be a bump, move the seat, Just goes off. We have had it professionally scanned and it is always the same sensor with the issue. We noticed certian models had recalls but our was not on the list for some reason even though it fits all the other models with same issue. The cost to get it repaired and a chevy dealer is astromical. There are too many dates to count of the light and sesnor error.

I believe the passenger seat occupant sensing and airbag issues from recall 16V507 have not been fixed. I am still having issues related to it, even though I had it fixed.

Smelled an odor of burning wires when using rear defroster. Defroster then stopped working. After further troubleshooting I observed the wire pigtail under the front passenger door was charred and burned. The pin inside the harness that was burned was the rear defroster. After further research I found this is very common for the Chevy impala. However no recall existed. I feel it is a fire risk due to the fact that the wires over heated enough to melt and char the plastic surrounding the electrical pin within the harness. Pictures was taken of the damage.

I have a 2009 with 77000 miles 0n it I have fix the knocking noise under dash 3 times now it is a actuator there are 2 of them. I have also found by spraying Carburetor cleaner in the throttle body just remove the the big air hose and spray all around in side this stops the the speed reduction control lite from coming on saying you have no power. The problem I'm having now is while I'm driving the dash lights go out and radio light goes dim. after a while the lights come back on bright and working great they go on and off when they want to The lights showing me the mileage works great all the time its just the dash lights going on and off and my car just pass smog in California in June. I now live in Texas ,I have to have my car inspection here and it failed do to a EVAP and a 02 sensor not responding. They tell cause I replace the battery this cause the computer to reset and these 2 sensors have not reset yet and I have to drive the car 100 miles to make sure they reset to the computer So these are the problems I have been having with my car. You can find your car problem on you tube by putting in the year and make of your car saying what light came up and usually its a easy fix

Driving home one night, August 8th, 2023 (thank goodness it was night) took a turn and got a service traction control light with a ding ding ding noise (I assume to alert me that something is wrong) and then it said engine power reduced which I assume happens because if your traction control is bad, it doesn’t want you slipping. Immediately called my father and he said to just drive it home and we’ll check it out. Not 2 miles later, my engine just stopped and it went into ignition. I couldn’t steer, I couldn’t stop because the engine was no longer running. I’ve driven a time or 2 (more like backed up) when I didn’t turn my key all the way and it was in ignition and that’s how it felt because it wasn’t on. This was very scary because I thought the car had just gave out. The engine just stopped and I got warning saying "STARTING DISABLED, SERVICE ENGINE THROTTLE " this is my first car, and after reading the complaints on it, I thought it was a recall. We ended up changing out the gas pedal, which made the problem go away right away, and I haven’t had issues with it since. Failure Mileage: 175K

The support frame rusted due to water collection from rain. This has caused the entire frame to rust through and collapse when the car was jacked up, with the manufacturer supplied scissor jack, to replace a tire. Because of this the DRIVER SIDE door is no longer able to open, causing the driver to be put at risk where they can not escape the car in case of an emergency.

"Air Bag Malfunction light is on. There is a NHTSA Campaign Number: 16V507000 (Air Bags, Electrical System) which I am associating with the failure and it tends to happen at the 80,000 mile mark which this car is almost at. Why isn't this VIN included in the recall? It's a 2009 Chevy Impala. Shouldn't this recall capture all of the 2009 Chevy Impalas?

While driving the car it would pop up a message saying “ENGINE POWER REDUCED”. Today while driving it home it popped up with a message saying “STARTING DISABLED, SERVICE THROTTLE” and then the car wouldn’t drive and I had to pull over on the side of the road. For months now when I drive and accelerate at times the car would almost grind. I believe it has to do with the traction control or the transmission.
