My vin should have been included in this: N182186881-01 - Special Coverage Evaporator Core Icing, Leak Revised Warranty section I have had the issue for many years due to not receiving the notice. The car leaks, hisses, smokes and does not cool at all. I was told I must only take it to them for 250 diagnostic but they also said it was a havoc reprogramming that cost the 2,500 to fix. I have a estimate from a triple a recommended mechanic that says its the evaporator coil. My miles just hit 80,000 but its been going on for years because I haven't had the money to fix it and make payments. Chevy arbitrator states the miles are low and the dealer i bought it from, Conly in Brighton Michigan, should put my vin on the recall list. They say they don't know how/will not. The arbitrator didn't give me on digit for her call back extension. …

The check engine light keeps turning on. And the car has trouble shifting. I took it to get it checked out and they informed me that it has to do something with the transmission and that multiple people are having this problem with the same type of vehicle.

I would like to place a complaint about my 2016 Chevy Impala ltz that I purchased from car max in glencoe, il on November 11 2016. I am a frequent traveler to central michigan and on my return trip to chicago on January 6, 2017, I was traveling south on highway 127 just south of mt. Pleasant michigan when all of sudden, the car lost power and it slowed down rapidly, there was a car behind me who almost rear-ended me, my wife and I were terrified. I pulled over to the side of the highway and put on my flashers. I looked at the dash and the following error lights were on (service engine soon, check engine light, reduced engine power, and stablitrack light). I looked at the owner's manual and it suggested that I turn the vehicle off and that it would reset. I followed instructions, turned on vehicle and all lights were cleared except check engine light. …

For the past 3 mo. Upon starting the vehicle I hear a "pop" noise. It only happens every once in a while in the morning or the evening when I get off work. Sometimes it will go a week or more without making the sound. The sound will not repeat itself if I immediately turn the car off and restart it. The 1st time I took it to the dealership, they siad nothing was wrong & they didn't hear the "pop". The 2nd time they said it was the exhaust so they repalced some hoses, the 3rd time, in which the "pop" was more frequent and louder, they said it was the starter sticking. After replacing the starter, a week later, I still hear the "pop" upon starting it. The vehicle is not in motion when this happens. Obviously, they don't know what the problem is if they diagnosed it as the exhaust first & then the starter and it's still making the same noise after servicing both said problems. …

I was stopped at the top of the hill on a private road. When I took my foot off the brake and pressed the accelerator, nothing happened. The car began to roll backwards and I pressed down on the brake. The brake was very weak and it took 50-60 feet and all of my pressure on the brake pedal to bring the car to a stop. After I stopped, I realized that the engine had turned off and the ignition was int he off position. I rotated the key in the ignition back to the start position to start the engine. I continued back up the hill normally after the engine was started. Luckily, there were no cars behind me on the hill or they would've been hit.

My vehicle turned off several different occasions once as I was driving freeway speed approximately 60-65mph engine completely shut off I attempted to put in natural and re start the ignition as the vehicle was still moving with no power vehicle did not start I merged to the side of the highway breaked to stop and placed the gear shift on park and tried turning the ignition on and still did not turn on a few attempts later car started. Another incident I was driving came to a red light as I was waiting for my green light my car shut off while I had my foot on the break I put the shift gear I to park turned the ignition on and car started

These impalas are downshifting on gears 2/3 and when trying to accelerate it is not shifting as they should this is from multiple auto shops and Chevrolet dealerships in dearborn and detour michigan are aware and both are staying they are getting alor if complaints about this issue I am. Not one of those individuals who have 4000 just sitting around I am also not working due to covid I have only had this car 15 months when this issues started GM and Chevrolet need to do a recall to check and replace and provide loaner vehicles at their expense.

I was making a right turn and the traction stabilization error popped up on my dash and the check engine light came on. I came to a stop and the car started shaking while it was at a complete stop. The car never slid or anything so I don't know why the stabalization error would come on and this is the 2nd time it has done this. The vehicle is fairly new so I don't know why it does this. Once I stepped on the pedal slowly to go again the engine felt like it jerked. I have read many complaints on this issue on other forums.
