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.

Electrical system: ignition
- What is wrong
- This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
- Risk
- If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
- Remedy
- GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1‑800‑521‑7300 (Buick), 1‑800‑458‑8006 (Cadillac), and 1‑800‑222‑1020 (Chevrolet). GM's number for this recall is 14299.

What 2009 Chevrolet Impala owners say
Most recent owner complaints, unedited.
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
2009 Chevy impala Airbag light comes on and off when it wants to bought it from a use dealer ship in 2022
Throttle body and throttle pedal
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.
