I am having the same problem with my 2010 Impala, I just got it 1 month ago and it was also a rental. I have not called the dealership yet . But I am really concern, with what I have been reading, I do not want to get the run around. I want the problem to be fixed. So if someone can tell what I need to tell them , so they correct the problem the first time around that would be wonderful. Or if you can point me in the right direction on how to handle this situation . I would appreciate any feedback

I apologize for the problems you have been experiencing with your vehicle. I would encourage you to take your vehicle to be diagnosed. Please keep me posted on any information from the dealership.

I am taking my car in today, Now the engine shut off while I was on the freeway yesterday, it stated ignition something I could not read it completely it due to me being so scared that the engine died, and I had to get off the freeway. The car started back up in about 10 mins but I was so scared that I just drove home . , What is going on with this vechicle I haven't even had it for 2 months and all I have been having is electrical problems. I called the dealership andf all he stated was we have to dignose it the problem. I am very disappointed with Chevy . The Service guys attitude was very rude. Hopefully it will be better once I get down there with my husband . If you can tell me if you have heard of this problem and what I can tell them before i get there to help fix this problem. I am ready to give this car right back to them.

I have a 2008 Impala and this has happened twice. I was on the highway and the engine dropped from 60 mph to 20pmh. VERY SCARY!!! I was told the problem was fixed and then it happened again today. Now, I'm told that they do not know why this is happening and they will try something else.
Disconcerting as I drive highways to work --- and it is a huge safety factor.
If anyone learns anything, I would be very interested.

I am experiencing the same issue. The reduced power displays on the console, the car slows to a crawl and the Check Engine light comes on. I travel 40+ miles each way to work in Atlanta traffic with speeds around 65-80 (big trucks). I am so frightened that this will occur when I am on my way to work and no time to recover and get off to a safe location. What is happening to these Impalas? I have transmission issue (jerking and sluggish performance); oil leak diagnosed on last oil change and now this. I am on my way to NISSAN today to trade it in as I am so tired of all the issues with this vehicle. I want to buy American, but not much confidence since I bought my Impala. I am surprised there are no recalls with all these issues. What is the threshold for this to happen? Or is it cost prohibitive for them to address it after such GLOWING recovery after the bail out? Chevy (GM) do the right thing please!
#13 of 486 Engine power reduced/Service Traction control

Not sure if this is related or not but after driving my 2008 Impala (3.5) in the rain for about 5 hours I had two lights come on in addition to the Service Engine Light. The service traction control and then engine power reduced as well. I had the code read and it came up P 2135. If you google the code you will see that GM has issues with a water leak somewhere in the A pillar on the driver's side which allows the water to run down inside the left foot kick and I understand that there is a wire connector inside that takes on water, corrodes and throws the codes. My windshield has been leaking so it is at the dealership today. They have the window removed and are waiting for a encapsulating seal for the window to arrive and then will work on the code issue. There is at least one bulletin for this fix plus a revision for the bulletin so they have had the problem for quite awhile. I have 125,000 K's on a used car so not sure if I will have to pay for the repair or not. Will find out tomorrow.

I experienced the EXACT problem today my car just displayed the message and then took me from 50 miles an hour down to 20 mph. Then the car just completely CUT OFF while I was still in drive and I could not even steer the wheel to get off the road. I had my 2 month old son and my 2 year old daughter in the car. There should be something done about this. It's scary and its overall DANGEROUS! It is not a situation that you can control because it is a computer issue. AGAIN...SOMETHING NEEDS TO BE DONE. I was in the middle of the road and it completely shut down that is NOT OKAY!
