I have the same problems with my impala 2009. Has anyone complained to Chevy about this? I have send them an email about the problem and I think we all should do this. If they get enough complains, maybe they will get this problem fixed.
Here is the website to send the complain:
I don't see why we have to pay for repair cost if they put in a faulty part.

I went round and round with Chevy customer service, they refused to pay for anything...I had to pay for the repair 160 was the total...I just hope it doesn't happen again...they told me that didn't have enough complaints to do a recall
#437 of 483 09 impala traction control and engine power reduced
Jul 11, 2013 (6:52 pm)
We would receive traction control alarm then shortly after we would engine power reduced. Chevy looked at the car and quoted $850 for the repair. We had a friend run it on a scanner which showed throttle position sensor. We purchased the part from Rockauto.com for around $60, received the part in 3 days and fixed the entire problem. While ordering this part we also had to purchase mode door actuator because the wonderfully engineered gears in it are plastic. The Impala has around 70000 miles on it and all of these problems already! I've been a firm believer in American made my entire life, but this along with our 09 Traverse and all of it's problems have really made me rethink it.

I have this problem with engine power reduced as well, on my way home last night from work my car just shut off on me. So i've only had the car 1 year so I called the dealer i purchased the vehicle from Royal Chevrolet in Coldwater, Michigan and since the car has no extended warranty it will cost me around 400 dollars to fix. Well this tees me off I can't believe GM don't recall these things to correct the problem. I guess i will have to quit buying Gm altogether my fiance has a 1998 Ford Explorer and it has 250,000 miles on it and she don't have these problems and she won't get rid of it for anything. there i go problem solved buy a FORD.

For my 2008 impala, I saw traction control light reduced engine power lights on when I had uneven air pressure in my tires, or the air pressure in one or more of the tires exceeded the low or high tire pressure. To fix this on the road, I turned of the traction control switch. I adjusted the air pressure in the tires later. The sensors are in the air valve, and they varry wildly in driving and garrage parking.

Thank you so much for the info. I recently got an estimate of $458. I haven't seen the light on in about a month so hopefully it has adjusted somehow. I don't have that kind of money to put in a new car.
#441 of 483 Same problem?
Jul 23, 2013 (9:13 am)
About 2 months ago I was on the interstate & I received the message 'service stabilitrak , engine power reduced '. I was using cruise control at about 75 which immediately cut off but the cars speed never dropped below 60. I stopped for gas about 50 miles later . Turned the car back on about 20 minutes later & the message was gone. Car drove fine. Took into the dealership & they said there were no codes coming back. Just 2 days ago I'm driving & the message reappaears but this time my car seems jumpy , hesitant at acceleration & when it does it seems to jolt . I have a 36000 mi warranty but I don't find it's even worth the money anymore because nothing is ever covered . I took it took a local shop & he says its the 'throttle body actuator ' . I read over everyone's posts & hadn't seen in mentioned , is anyone familiar ?

The last mechanic told me that was what I needed although diagnosis at AutoZone said something about a sensor in the gas pedal. Anyways I was given an estimate of $458 to replace the throttle. I haven't received any error messages for about a month. I emailed GM and they called me; I asked about a recall and was told the don't have anything in effect for that issue. I've only had my car 1 year and to be experiencing this is not right.

If you haven't already, you should report the issue(s) to the NHTSA at www.safercar.gov.
They're the only agency authorized to gather consumer complaints and investigate them - that's how many recalls come about.
