    Hi ihotaling

    I am so sorry that you are dealing with a repeated issue. Work/parts done at a GM dealership is warrantied for 12 months. The wire should be replaced free of charge. If you want more information or need my assistance could you please email me at socialmedia@gm.com. Please include a link to this thread or a brief description of the issue, your current mileage and VIN. I look forward to assisting you.

  • Most entries about loss of power are for 2008 - 2011 Impalas, most of which have some miles on them. I test drove a 2012 Impala that was repossessed by a Credit Union and has less than 13,000 miles on it. My main complaint was that it was sluggish, without the quick acceleration that I like in the car (and also, the seat was uncomfortable, but most of them are!) That's why I started to research Impalas. Any recommendations for what I should do to check it out further? Have there been any recalls for 2012 models? Would I still be getting the power train warranty if I buy this car? And why wouldn't it be covered under it, if it is a known problem from past years and wasn't fixed in the newer model?

    I believe the 2012 Impala has the 3.6 liter V6 engine. Numerous problems have been reported on older versions of this engine (e.g. 2005-2008 Cadillac CTS's and 2007-2008 GMC Acadia's) with the timing chains stretching. If you want an Impala, I would look for a low mileage 2006 or 2007 model without the Stabilitrak. Most "reduce engine power" problems are associated with Stabilitrak (GM's version of electronic stability control). The 2006/2007 models have GM's 3.5 or 3.9 liter V6 engines which are generally reliable with the exception of head gasket and crossover pipe gasket problems. I would think a 2006/2007 would have had the gaskets already replaced. A well cared for 2006/2007 could be a good buy. Good luck.
  • I will also never by a chevy again. I was so proud when I bought my 08 impala in 07 but I had issues practically from day 1. Thank the lord a lot of my issues surfaced while it was still under warranty, but I'm dealing with the reduced power issue now. GM...you suck!!!

    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!
  • 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 son is having the same issue this morning with his 2007 Impala. Can you tell me which sensor you had changed/replaced? Thanks!

  • 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.
  • What kind of sensor is it called
  • Annoyed10,

    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...
  • I have bought new tires every year since I have had mine,I was always a chevy person too,but I am thinking of switching,I have told all my friends and family of my problems,I am sure none of them will ever buy an impala.
  • Hi Sarah,

    I'm back and still disgusted. Same issue. Again. And again, while on a busy highway, in the DARK and ICY winter weather. Clearly if this is weather related (based on my Jan 2012, Jan 2013 and Dec 2013 issues), the design is shoddy. I can't wait to pay off enough of this piece of crap so I have an option besides fearing for my life every time I get into it.

    When will a recall be issued for this? And please do not ask me to contact customer service. Their only assistance last time was to look up my car and tell me it was still under warranty and to take it to a dealer and "discuss my concerns". SO helpful. Not.

    This is a KNOWN safety risk that continually occurs with no action on the part of GM. That is negligent in my book.

    No Love,
    Me

    this is ridiculous , almost got into a big accident two days ago... engine light came on and reduced engine power light, then car shut off, since wednesday been over shop and no one knows what the problem is ,snap on scanner said the amount of alcohol was ditributed to engine is 75% (not Gas) code p0172 (running rich) . Wow. why is it showing more alcohol level than Gas?
    reset the fuel ratio (scanner said 1% alcohol) and car is running fine for about two minutes then roughand 75% alcohol. funny isn't ??
    any suggestion GM? anyone?
    scared in ny
  • Its 2 months later and same problem and just about had a major collision. Driving 25 mph when bells go off, engine light comes on, and my car almost completely loses all power. On top of that it is snowing and the car behind me hits his brakes and ends up on the curb so as not to rear end my car! Really GM! ?Still don't think there is a reason to recall this shotty product of yours? Yes I am angry. I put my family in this car thinking we are safe but we are not. NO MORE GM/CHEVY cars for this family. Unfortunately we will most likely have to sink our Christmas money into fixing this lemon...AGAIN! I'm stuck with this nightmare until we can find something affordable but safe. Very disappointed for your lack of concern for those who are keeping you in business. This is a problem that has been going on for years. Shame on GM!

  • So why do you only respond to certain people on here. We all have the SAME problem. In fact, I just fixed this problem 2 months ago and now it is doing it again, but 10 times worse. The 2011 Impala that your company made just about caused a wreck. It was snowing when my car almost completely lost power. Bells went off, engine light came on, reduced engine power/service stabilitrac sign came on. The poor guy behind me didn't have a clue what was happening since my car pretty much just stopped on slippery roads. He or she...ended up on the curb to avoid me. I only wish that they would have stayed so I could get them as a witness to a near collision so as to point out the importance of this safety issue with your companies vehicles. Not only am I putting myself in danger every time I get into this death trap, but also my family. Its not like I can just go out and get another car!!! Now I will probably have to pay $300. plus again to fix this witch. There goes Christmas! If you are thinking "Geez, what a jerk" ...then try putting yourself in my shoes. Would this be ok with you?
