#431 of 483 FIXED THE PROBLEM! Changed Accelerator pedal sensor on impala
May 27, 2013 (11:52 am)
My issue was that I was four months into driving my new 2009 chevy impala and while driving on the highway driving 65mph my car showed flashing signal reading "engine reduced speed" "check stabilitrack" and my check engine was on. This all happened yesterday. After researching and hearing complaints about GM and how they are charging people anywhere from $250 - $600. We decided to take matters into our own hands. Once this happens you must fix it right away or it could lead to transmission issues. We took my car to autozone had them run a FREE test on my car order the accelerator pedal sensor which is $72.99 at autozone. And my dad replaced it today within 5 minutes. My check engine light no longer on. My car is no longer jerking and they're are no scary flashing signals! I can't believe GM did not send out a recall on that faulty part with all of these reviews. Crazy. Hope this saves someone some money!! For more info visit my YouTube video. Step by step instructions on how to DIY!

#433 of 483 Impala Engine Power Reduced
May 28, 2013 (6:34 am)
Ok, can't believe it, but I had my car in last Wed. May 22, got it back Thurs. May 23. Was told they believed the battery was causing the problem! I have had the car in for the same problem and had various things done. Well, lo and behold, went out today and the same exact thing happened for the 6th time!!! Thank God for OnStar. Called them and they got me assistance. Guess paying that $170 for a battery wasn't the problem!! I have a 2010 Impala LT and have been dealing with this problem since January 2013. What we have noticed from the last time it happened, it seems as if every time it has rained the night before or is raining at the time, this problem has occurred. I am tired of seeing Engine Power reduced, service Traction Control and service Stabiltrak!! I am losing my patience with this matter!!

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.

Be sure to report it to the NHTSA as well - the link is at the top of this forum page.

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.
#438 of 483 2008 Chevy Impala

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.
