It must have something to do with the oil change because before that everything was oil...I when for a regular oil change and now I have oil spots on my pavement in the front and back on my HHR.
Reminder...I always back up in my driveway and I'm the only car who parks there.
If only I would have oil leaks in the front but...also at the rear? Weird.
I am sorry you are experiencing an oil leaking issue. Are you thinking about going back to the dealership to check out this concern? Let us know if you would like assistance throughout this process. We can be reached via Email at socialmedia(at)gm.com.
Sincerely,

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.

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!

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'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,

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?

I had the same message about Stabilitrak/Traction Control/Reduced Engine Power on my 2009 Impala SS with 94,000 miles. Car slowed to 40 mph. I pulled off and waited a couple minutes for computer to reset and drove safely to my dealer. Code for Throttle Position sensor. Since I was still within the 5 year/100,000 mile power train warranty, the dealer replaced the throttle body without charge. He also found excess play in the left front wheel hub and replaced that at no charge under the power train warranty.
I came across this forum tonight because the same thing just happened to me today with my 2011 Buick Lucerne CXL. I had just left my job and was about 3-4 miles along, getting onto a very backed-up ramp to the freeway (subzero temps, black ice and snow today). Another driver had just let me merge in front of them on the ramp and my car just stopped. I saw alternating warnings of 'Service Stabilitrak' and the 'Low Engine Power' thing too and also the service engine light. In my panic I can't remember for sure but at times it seemed like the brake pedal was intermittently stuck down as well (not 100% on that). I pushed the OnStar button for assistance- they called for a State Patrol Officer who arrived maybe 10-15 minutes later. My car then did move as I followed the Officer to the nearest exit and the car was pretty shaky/bumpy at times, feeling like it could stop again at any time. I had to wait a couple of hours to get a tow truck and by then the Service Stabilitrak' and low power warnings were gone- only the service engine light was still on.
I bought the Lucerne new in 2010 and it has 53,000 miles on it. I just paid about $500.00 for a 50,000 maintenance at a GM facility about 10 miles from my home and thought all would be well for the winter but obviously not! I have a 34-mile commute through heavy traffic (as well as some wicked winter weather conditions at the moment) and after reading what's been posted here am not feeling very comfortable about what might be to come. Due to transportation issues I had the vehicle towed to a local auto repair shop- not a GM specific one- so will have to see what they come up with. Obviously this issue has been going on for quite some time and it does sound like some type of recall should have been done. I know that on the 50,000 service that I just had that they did a couple of warranty things but apparently they weren't aware of this issue. Like some others have posted I too fear for my safety because with the type of weather, traffic and freeways that I have to deal with, a loss of power/control could be very dangerous to myself and others.
I have a 2007 Impala with the engine loss of power issue. It just started today. My mother in law had a 2006 Impala that had this same problem. hers started when her mileage reached about 65,000 miles. my impala has 66,000 miles on it. I don't have the resorces to keep going to a mechanic over and over to get it fixed. I would like to see if anybody has a true fix for this issue. It sounds as if maybe a recall is in order.
I had to take my 2011 Impala in for a third time. I told the mechanic that Chevy had a pretty good money maker on their hands. Of course he didn't say anything. I asked him if this would take care of the problem and his answer was that there are several stabilitrac sensors and he couldn't say. I put $900 into this car in less than 3 months for the same problem. I almost got into an accident because of this problem that Chevy refuses to address. I would like to know what must happen before they finally do a recall on stabilitrak. I think it does more harm than good. I have written GM with no response. Am I surprised...no. We are nothing to them, they got their money maker and are not about to give it up.
I have a 2013 Chevy Impala with the same issues. reduce power and traction control issue. It was in the shop during Christmas week and now it has been in the shop for the last 6 days and they cannot seem to find the problem. Very frustating, I drive 3 hours a day to work, very concerned with the reduce engine power while driving on interstate, safety is my major concern. You cannot drive safely on interstate at 40 mph. The car only has 24,000 miles on it and already having these type of issue.
I have a 2009 Impala LT. The Reduced Engine power problem started around 42k. The dealer replaced the accelerator pedal. Then at 80k it became sporadic, but same code Reduced Engine Power. I took it to a dealer they could not find anything. Problem continued. The car will code even when sitting in the drive way. I have changed 3 throttle body's and taken it to the dealer to get programmed, and still it continues. Recently it does it when it’s raining or icy, or snowing. I believe it has to do with the wheel speed sensors and GM needs to pay attention to were they place the wiring harness mine was on top of the engine bolt. I moved it and wrapped it with electrical tape. It helped but still trips. Today I reset the codes, turned off the traction control; I drove it 2 miles from the house barely 30mph, and caught a slick spot. The Reduced Engine power came on and shut the car off while I was turning. It keeps tripping P2176, Throttle Position, P2138 Accelerator position sensor. I love the car, but it has become Dangerous and blimishing the Chevy name! The problem is not only to Impala's, but to Malibu, Equinox, Traverse, and Silverado. Please don't make it a Ford Pinto problem, and Chevy needs to recall this before people get hurt or killed.
Well after reading these post Chevy can count on me not buying a impala. I already own a Yukon with the same issues. Thought buying a car would make life simpler for me until the Yukon is figured out. So long GM/Chevy from a long time buyer. Now it is time to take a look at Ford!
Add another one to the list- 2010 impala same thing have not taken to service yet just came on last night then went out came back this morn. Really makes you wonder why it has not been a recall. I use to be a diehard Chevy but lately not so sure. 55,000 mile
Day 1
Hi all,
As I see on the forums there are many issues with what seems to be the Throttle Body, sensor etc. Here is my wonderful story and I will be updating regularly in the next few days. I will add that I commute at least 2 hours per day and rely heavily on my car for work and to take care of my 2 children - 1 of which is special needs.
Car: 2011 Chevy Impala LS 61K miles (90% of which were highway) Running full synthetic oil - changed every 5-6K miles
Problem:
Left work last night and not driving for more than 30 seconds when the engine light came on followed quickly by what can only be described and mild to moderate jack hammering of the car and the "Service Stabilitrak & reduced power to engine" message. I pulled over, checked the manual - then Google/Edmunds which brought me here.
Status:
I got a ride home after securing the vehicle and came back this morning. Got it towed to the dealership and was told that it was out of bumper to bumper warranty and that it wouldn't be covered under the Powertrain warranty if it was the throttle body or any of the associated sensors.
I'm currently awaiting the call back from the dealership regarding the diagnostic result ($125) and will post everything as it becomes available in an attempt to help anyone else having a similar issue.
It's a shame too - after the research I had done on this car I thought it would be more reliable than my old 2005 Ford Focus. But since May 2013 I've now been left dead by the side of the road twice... first time with a blown thermostat!
So - as I said - waiting on service calling me back. I've also taken the liberty of emailing socialmedia@gm.com with the details of the vehicle. I'm trying to take a positive approach to this in the hope GM customer Service will pull through for one of its customers... I can only hope they do!
Good luck and safe driving! Updates coming soon!
Day 2
So I sent a little email to GM regarding this issue and my situation.
90 minutes after sending the email I received a call from a GM customer service rep that passed me through to a district agent. Linda (the agent) was exceptionally nice, took the details of the issues I'm having as well as previous issues with the vehicle (blown thermostat), contact info for the dealership/service center I dropped the car off at etc.
She said she'd contact the service center directly to follow through and see what could be done with my case.
Upon hanging up the service center called and confirmed that it is indeed the throttle body, that it isn't covered under the 5 year/100K powertrain (as of 2010 on all models apparently) and that it would be $650 out the door for parts & labor.
At this time as I need the vehicle I've approved the work and will be picking it up on Saturday as I'm currently travelling for work... more updates to follow!
Follow-up as of today (Day 3)...
No return call from the GM district rep but got a call today to say my vehicle had been repaired, that the GM rep had called the shop directly and that GM has discounted the cost of the repairs.
Initial cost was an even $650 + tax ($679) Discounted cost is $571.98.
At this point I'll be forking out the money as I need my car back. Not sure if anyone else has attempted to contact GM with any similar results - would be good to hear from you if you did!

I am totally sickened & disgusted by the fact that there are all these stories on here about people that are having serious, possibly life threatening issues with their Chevy Impala's, and nothing is being done about it. There are pages and pages of the exact same issues with not always happy endings. I got my first message this morning on my car about the engine power being reduced. After spending some time reading all of these posts, I am quite frankly terrified. Why has nothing been done about this? I am so pissed off about this. We only matter when we are paying for the vehicles?????? I'm just sick.

I was driving and the REDUCED ENGINE POWER warning flashed and check engine light came on. Also the car dropped down to 20mph while I was driving on a very busy street.Thank God I wasn't on the highway !! I took the car to AutoZone to have the check engine light diagnosed and came up with two codes : P2119 and P2135 . 2135 goes to a throttle position sensor but they told me at AutoZone that it does not come separate and I'd have to buy the whole throttle body. I researched online and discovered that now they have started selling the replacement part separately (AC Delco part 19300180). Is there an easy way to tell what I need to replace ? I really don't want to go to a Chevy dealership as I've had bad experiences already with the two closest to me.
Had the issue today with my 2009 Chevy Impala which has 67,000 miles on it. Was on the highway when the service transaction control and engine power reduced came on. Car would not drive over 30mph. Thank god the weather was bad and was only driving around 30-40. I was able to get off the high and drove back home. Called my dealership Sunny Side Chevy in Elyria Ohio and they had me bring it in said by me telling them they knew exactly what was wrong. $454 later the replaced my Throttle Position Sensor, Gas Pedal, Solenoid, Harness. They do a good job at the dealership and always put me in a loaner car so I can go about my day. This seems to be very common in Chevy's and even the dealership said the same thing. Why wouldn't GM recall on this. If the weather wasn't bad this could have turned out different from me and I could have been hurt or killed in an accident. This will be the last GM OR ANY AMERICAN CAR I buy. I would like to stay American unfortunately it is just not practical.
