#318 of 483 2011 Chevy Imapala - Reduce Engine Light
Feb 26, 2013 (7:34 am)
I purchased my 2011 Chevy Impala Lt. with 31,000 miles on it. I was on my way to work when the Reduce Engine Light/Servce Stabilization Trac/Engine light came on. When you turn the car on , it sounds like a vacuum is on. I went to Advanced Auto where they ran a diagnostic on the car and told me that the (Throttle Position Sensor) was going bad (Codes-P20/21) and that this was a dealer part. I then went to Grays Chevy dealership and they told me that I would have to buy the whole Throttle assembly which would be ($399.00 plus tax) and with the labor, it would come out to $500 plus. I have a 100,000 powertrain warranty which I thought would be covered only to be informed that it wasn't.
I purchased the part and had it installed and for (1) day, the car sounded fine. The next day on the way to work, going up a hill the Reduce Engine Light/Servce Stabilization Trac/Engine light came on again.
I would really like to here what GM is doing about this problem that thousands of people are having with there chevy impala's. I figured if I bought a fairly new car, that I would not have to deal with these problems. I guess I was wrong

I just had this happen to me also. Took it to my buddy that has a dealership. He said this is a common problem. It was a throttle positioning sensor kit. It was $110 for the kit. They installed the kit and cleaned up the throttle body and works great. No problems so far. I would hope that GM does do something about this so I can recover the money I spent but we will see.

Ok is Chevy planning to own up to this???
This is way to common issue for chevy to give a blind eye.
I have a 2010 Chevy Impala and basically its falling apart like seriously 58000 its got so much electrical issues starting from airbag right to rear window defrost which was livable but now this Stability Trak that runs like I'm on a motor cross track and loss of power.
I've always liked chevy but now I can't even stand to drive by a lot.

Today as I was driving to work, I too saw a message on my cars dashboard that said "Low Engine Power" at that point my car started to drag and the engine light symbol stayed on.
After reading the several messages surrounding this issue. It appears that GM should insist upon a recall for this situation so that the consumer does not have to pay to get this corrected.

#325 of 483 impala reduced engine power

Hi, it's annoyed10 with an update. (see posts 311 and 314) Last time we met, the part was supposed to be in on Monday (throttle position sensor) and the service guy said they would look into having the job covered by chevy. Well, it is now Wednesday. The part has to be ordered from the manufacturer and I was told would not be in until Thursday, so I would not get the car back until Friday at the earliest. But, I could PAY EXTRA to have it overnighted, and have the car back for Wednesday. The cost (since it is NOT Covered) of this and Everything else would run between 300.00 and 350.00 depending on shipping charges for this small part. So, I call on Wednesday, NO PART, it is backordered and now they have to find one at another dealer who is willing to give it up. (Only God knows what that will cost me). Hmm, a small sensor, from a manufacturer that makes 10s of thousand of them, and they can't keep up with demand? Does anyone else see a problem with this defective system? Chevrolet/GM evidently doesn't see the problem, even though the messages on this board keep adding up, and this is just one forum on this. Supposedly, the part will be here on Friday, and the car will be fixed then. Tune in on Friday for the next installment of this soap opera.

I own a 2009 Chevy Impala and I am having the EXACT same issues as you are. My car was just in the shop yesterday (Chevy Dealer) and I paid around $700 total to fix this supposed issue.(Harness broken in left pedal & air bags were bad) The strange and fishy thing is that almost EVERY post I read has the same issues. My car left me stuck 2 times and also almost caused an accident. I have two children that also are in my car on a daily basis. I called GM they could care less. They try to smooze you with B/S. I am going to attempt to take this further. I thought I was buying a reliable car that would last me for the price I paid. ENTIRELY WRONG. My suggestion to anyone is GET RID OF IT NOW IF YOU CAN.
#327 of 483 REDUCED ENGINE POWER MESSAGE
Feb 28, 2013 (6:37 pm)
I have a 2007 Chevy Impala LS and after my REDUCE ENGINE POWER light came on I came to this forum to get some feedback. I saw that this has been an ongoing problem for what looks like hundreds of Chevy owners. I've since had my sensor replaced for $25 by a mechanic I know. I paid $104.00 for the sensor (from dealer) but saw it online for about $70 (didn't have time to wait for deliver). I was told two different things about the throttle systems. One was that the whole thing had to be replaced and the other was that I needed to know if my system was one that allows you to remove the sensor separately. I decided to go to my guy in the end. Car running fine so far...had it done about a month ago and it took less than 15 minutes for him to do the work. Nevertheless, I'm a bit upset that it has not been a recall on this. Just saw a Ford vehichle problem just like this and a recall is expected. PLEASE POST RECALL IF IT HAPPENS SO I CAN GO GET MY MONEY BACK FOR THE PART! THANKS
