I am having the same problem with my 2011 Impala I have only had the car 2 yrs in March. Since I have had the car I have had to take it to the service department 3 times. Once because my tires were being ate every other week. Found that my tires lean inward..........Second time it was making a weird noise and they said it was my power sterring pump and now this! It should be a recall on these cars, GM is killing our pockets for their mistakes! FYI as I sat at the dealer I watch 3 more Impalas drive in with the same problem!

I had the issue with the knocking in the glove box area the car. The car was about a year and half old at the time. The dealer had to replace a switch of some type that is connected to the AC blower.
I own Chevy Impala LT 2008, three weeks ago, I took my kids to July 4th fireworks celebrations. then on our way home; we were stranded in middle of road because the REDUCED ENGINE POWER and check ENGINE LIGHTS came on simultaneously. it was scary with all those intense traffic in the middle of the road with kids in the car. on July 24th, 2014 after work; I was going to see a new house, we wanted to move in. Again I was stranded on the road and lost the appointment with the landlord who in turn gave away the house to some one else. I went around to Google the issue until I accidentally just got on this site an read all the similar problems that every one else is having and quite frankly, i cant believe that the GM is not willing to do something to fix this problem. Seriously!!!!! you have somebody with children driving down the crowded road and their cars have no power. That is totally dangerous an they wont even fix the damn problem!! is this how buying american was almost going to take our life? I have already spent over $439.00 and can't afford doing this again and again. can some body fixed this problems to save the life of those who choose to buy and drive made in america!!!!!!!!!!!!!!!!!!
WHY is this not a recall issue? For the past year, my car has had this issue so many times I can't keep track. It's happened multiple times in one day, it's happened right after my car has been on the computer and the code cleared. My code consistently comes up as a general computer error, but the dealership continues to insist they replace other parts. So-far, this has helped with NOTHING but draining my wallet and wasting my time. I would love to have the money to continue to shell out for repairs/replacement/whatever, but if I did, I'd be more apt to just get rid of the car and get a new one. I've been in my car with my two toddlers in the back seat on the freeway and city streets when this has happened. Again, I'd love to have a different car to drive them around in, but I don't, so I'm guessing someone has to die in a wreck after this happens before GM will step up to the plate and recall this. I come from a family of auto workers and have worked at our local plant myself, and I'm ready to start buying foreign. Shame on anyone who works there, knows this is an issue, and has no problem sleeping at night while doing nothing. You have how many thousands of cars recalled already--why not take care of the rest of your mistakes?
A reporter would like to speak to an owner of a GM car who has had a recent experience with a dealer service department during recalls.

I've had a 2007 Impala for 3 years now and have had nothing but problems with the "engine power reduced" and "starting disabled" codes. The throttle body has been replaced three times now (fortunately the second one was still under warranty), the accelerator assembly once, and then the dealer wanted $750 to change the battery and one battery cable. I've had it in the shop six times now for the same issue. Been stranded on a busy Chicago freeway, at the hospital parking lot after my child's brain surgery, at the grocery store, on our anniversary trip, all over. Unfortunately, we are still paying on the heap of junk and can't afford to get rid of it....or keep it. Does anyone know if there is a class-action lawsuit? It doesn't appear that they've fixed this issue on newer cars either as I had the "engine power reduced" code on a 2014 Chevy Cruze I just rented for our vacation. The Cruze's electronic trip and MPG display disappeared, the car overheated, and it gave the engine power reduced code.....and the rental only had 9,000 miles on it. Not what I would expect from a car with so few miles. The rental agency had the car towed and replaced it with another 2014 Cruze....but fortunately that one got us back home. I've always been a GM man but now probably wouldn't buy one that was made after 1998 as my older Saturn keeps running flawlessly at 260,000 miles now
I have a 2008 Chevy Impala and do mostly highway driving. I bought it from a dealership with 46000 miles.It ran fine through that winter but in the warmer months I was constantly getting the engine power reduced. Took it in and the dealership mechanics said that the 'sure fire fix' was to replace the throttle body sensor... They did that and cleared the code and sent me on my way ($400) Then on the ride home it did that same engine power reduced, I turned around and they said that there was absolutely nothing they could do for me. So i just drove it like that (as frustrating as that was). Then in the winter months, everything was fine and no engine power reduced until the warmer months. Then this past weekend it stalled for the first and only time (at roughly 76000 miles) in a drive thru. I took it in to a different shop today and they said they see this issue quite often! They said the code I was having was P1516. I dropped it off and a few hours later they called back with great news!!! They checked the wires and all was good. THEN they checked the battery. That was where the issue was! They put the battery on a charger and an hour later they tried that out. NO PROBLEMS and they diagnosed the issue to being a bad battery giving a low reading to the sensors causing the fail safe mode to occur! For them to look at it, it cost me $63 for them to diagnose the problem and they warned me to avoid cheap batteries!
Glad to hear your dealership was able to take care of this issue for you, tyler995! If you happen to have concerns with your Impala in the future, we'd be more than happy to offer our assistance. We're available via private message if interested.

Nine days after getting my car out of the shop after getting the "engine power reduced" code issue fixed again (6th time), the "engine power reduced" code is back. Was 55 miles from home and had to limp it all the way home as I can't afford yet another tow. Wow, this is frustrating!
I have 2008 Chevy impala LT while driving to my daughters this past Sunday the reduced engine power light and the engine light came on!!! The car wouldn't go above 20 miles

maybe GM should issue all Impala owners a code scanner for FREE!!!
Needless to say I WILL NEVER BUY A GM PRODUCT AGAIN.

Amber N, please assist all of us in getting a resolution so that we do not cut our ties to GM and go with another vehicle company.

FWIW. A top tech would make easy work of the majority of the reported problems in this and many other threads just like this one. The trouble is the culture of the trade has made it so that they are few and far between and its going to take years to undo that for the consumer. That isn't even going to start to happen until the manufacturers and dealers accept their role in this and take the steps to address it.
I truly apologize for this, and understand how uncomfortable this may make you feel. We would be happy to look into this further for you and contact the dealership on your behalf. Please sent us an email at socialmedia@gm.com ATTN: Patsy including your VIN, current mileage, contact information and a preferred dealership. I look forward to your response.

PROBLEM: The reduced engine power and stabilitrac warnings came on with check engine light.
ACTION: Work with local repair and dealers of problem and will sell impala once the issue is fixed. Cannot have my young daughter with me in that car.

Trying to make a long story short, the first time I had an issue I was on a short trip on the highway, a day after a large snowfall. The highway was clear and clean though the day was very cold and the car started shaking with the traction control light coming on but the engine reduced speed thing etc did not happen. I did reduce my speed to reduce the shaking. I thought wow is this road in that bad shape or are my tires coated in hardened snow and then I thought it might be snow/ice build up in the wheel wheels. Got off the road as soon as possible and sure enough every single wheel well had snow/ice build up that was actually rubbing against the tires and it was ice hard. Managed to get that all removed and the car started with just the check engine light on so I stayed on the city roads and then took the highway home, all was fine. and check engine light did not come on the next day.
Had this problem a few more times a few weeks later on the morning start after a very cold night. Same routine Start car, car starts to shake get the Service Stabiltrak warning, engine reduced speed. Shut engine off. Cleared out any and all ice/snow from the wheel wells. Car starts no problem with just the check engine light on and after a few starts the check engine light goes off.
Was at the dealership for a service appointment and mentioned this as an afterthought and the service rep said yeah we've been getting a lot of complaints about that you just have to keep the ice and snow clear. And I didn't pursue it.
Everything fine for a week until the weather got colder again and had issues the last few days.
But now I realize this is dangerous and ridiculous so to the dealership asap. I am disappointed that the service rep seemed so nonchalant about this issue and didn't suggest getting that looked after. After all I didn't have this issue in previous years though this winter has been particularly cold - I don't recall the snow/ice build up being so hard even last year.

I was assuming it was a sensor issue but I realize from reading this forum it might be something more serious but at least I know what the dealership should be looking at and how much this may cost me.
