I can't agree more! I will never buy a GM produce. I had to replace the gas pedal, and last week I had to replace a side airbag to the tune of almost $750.00 The way they have it set up is if one air bag goes bad, it disables the complete airbag system so none of them will work. So in my opinion GM products are unsafe to even drive, and will never touch another one!
#478 of 486 Same problem for at least a year

I have a 2009 malibu. This same problem started for me around 80,000 miles. I had gotten the lights before then but none of the symtoms til around 80. I get esc off, traction off and reduced engine power. I can always tell when its about to happen because it will start jumping and jerking while trying to shift. Then the lights come on along with engine light and the car starts shaking violently and then most of the time will stall out unless i turn it off for at least a few minutes. Sometimes it will be ok for a little while sometimes it comes right back on. I am currently at the dealer for the 6th time. Up until now they've been covering the repairs under the powertrain warranty. So far i have had some wires under harness replaced, ecm replaced, throttle body replaced and timing belts replaced... Today they told me its some fuel wiring and that this time i have to pay $300 out of pocket. Which i have to at this point because i need the car. My husband is a government employee currently not receiving a paycheck so its important that i get my car back and get to work. This is my second time here just this week. I just picked the car up last night because they couldnt get it to duplicate the symptoms. I picked the car up after the service dept closed or i would have taken it right back but it did it to me literally as i was turning out of the dealer. I emailed GM yesterday and theyre supposed to be calling today! I am so overly frustrated im at the point of trading it in and making it someone elses problem because nothing they do seems to fix it! The last time the wiring under harness was replaced it went 5000 miles before starting again so even if you think its fixed its probably not fixed!! Beware

I have a 2011 Impala LT luxery edition with 41,000 miles, I bought it used about a year ago with 19,000, and it has had the Service Stabilitrak and engine power is reduced show up twice. I called the dealership that I purchased it and they told me they could run a diagnostic (for $69) to tell what is wrong, I took it to advanced auto parts and got a free diagnostic done. they said it read that there was a bad throttle positioning sensor switch. I went to the dealer and asked if it was covered under warranty, its not. I don't k know anything about mechanic work but I am going to check into price and try to do it myself. This is the only Vehicle we have and it is used to transport my two young kids (3 and 6) back and forth to school, activities, and dr. appointments. It is ignorant that it is not covered under warranty and that there are so many complaints and problems that GM is ignoring.

I too have this issue. 2009 Chevy Impala LT 5.3L, Accelerator Pedal Position sensor error. Not covered by warranty - WHY NOT?!
Is there anything new about recall on this part?
I am inclined to pick up the sensor at local parts store and replace myself.
There appears to be a simple replacement procedure? Any reason why I should not just spend $80 for the part and replace myself vs. $350 at the dealer?
GM should certainly look into the quality of this sensor!

Just buy the part and replace it yourself. It is a easy replacement. Do not give GM any of your hard earned money! I know I will never buy another GM product.

I had my car taken to the dealer and what they found causing the (engine reduced power) was a short in the wiring in the harness by the plugin socket down under the power steering pump. they cut the plugin socket off put a new one on. The part cost 35.00 dollars but the lieghbor cost was 360.00 bucks for 3 hours because they had to pull the power steering pump to get to it. from what i see this problem happens around plugins the wire gets stretched shorts out over time. i hope this helps out some.

Has your car acted up since this was replaced? I dont see any posts on here since March so I'm Hoping it hasn't.
I have a friend who Finally got a nice car and now it's doing this (Chevy's Flag ship Impala).
I'm a Dodge guy but I've always liked Chevys. She's had a lot of issues this car. She got it with low miles at a pretty good price, beginning to figure out why...
