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. I do have proof of the car having no air at 49,000 miles when a mechanic couldn't find the issue because it was to far down in the car. I don't trust taking the car to them after being diagnosed without seeing the car. BBB auto said I exceeded milage but i wouldn't have if I would have been informed asap My vin should have been in the recall. I have the same make and type of car. Why did they exclude me? I hardly drive the car and was an essential employee . everything was closed I was in the year allowed and under the miles if I would have got the notice Please help

I was driving and entering [XXX] at [XXX] when my power steering went completely out! I was unable to steer my vehicle at all and was on a windy road with my children in the vehicle! I pulled to the side of the road! Shut my car off waited a couple minutes and turned it back on and the problem went away! This has happened twice now. My power steering is due to it being electrical and not a fluid issue. This is extremely dangerous as you are unable to steer the vehicle at all when this happens!

When my car is exposed to water (rain, a car wash) the trunk completely floods and does not drain. It has flooded so much now that my amplifier does not work. I took my vehicle to Chevy to have the known recall on this vehicle repaired but Chevy claims that they will not do anything for me. I am afraid that the car can potentially catch fire and burn my home down as I park this car in my driveway. With this being a known recall for this vehicle, can I please have this fixed immediately!!!! I have already replaced my tools that have been damaged, please just have this fixed or id likely take further steps after this. I have been going back and forth with GMC and Chevy for over 7 days now! Just recently, my car was producing sparks from the trunk area, THIS IS NOT GOOD!!!

2016 Chevy Impala with 3.6L V6 has a design fault that causes failure of the evaporator core including leak of freon and inoperative Air Conditioning. Leak of freon and lack of air conditioning in 100 degree plus outside temps endangers the driver and passengers. Local auto service and local dealership both confirm failure of evaporator core. Issue has been identified by Chevy manufacturer and TSB issued N182186881 to cover repair/replacement at no cost to the vehicle owner. However, database is intentionally exclusive of VINs without cause or rationale. There is documented history of Chevy/GM declining to authorize service to affected vehicles on online forums and even at my local dealership. No warning. issue is Air Conditioning failure. upon first warm day in the spring, the AC blew hot air. This suggests legal dodging of addressing the issue by manufacturer. Manufacturer should honor their bulletin and verify all applicable 2016-2018 Impala with V6 are added to the database. Owners and potential owners must be informed of this issue that manufacturer has admitted to already.

For approximately 2 months, my 2016 Impala LTZ, would display a message on the small screen in front of the driver in the dash, stating for the driver to, "press ignition button again to turn vehicle off." The worst part about it was this would happen very randomly whether I would be driving in city traffic, or be sitting in a parking lot at a local store. I took it to my local Chevrolet dealership. Five different times, because they were not able to get the occurrence to duplicate for them. They replaced the ignition, as well as other suspected parts with no resolution. Resolution. Ended up costing me over $1,200. That was the first time I took it in for this issue. The other four times didn't cost me anything because they hadn't fixed the issue. Come to find out it was a wire on the body control module that had some of the insulation sheathing removed, which then in turn caused the wire to ground out on the car's frame. Just thought I would put this out there in case anybody else goes through it because it wasn't real inconvenience.

On Fb 08 2022, at app 5:30 in the evening my 2016 Impala had a non-driver directed surge of speed. As I was slowing down to enter a driveway, the vehicle surged forward powerfully. I was able to press the brakes forcefully engaging the antilock mechanism. The vehicle shook as I continued to apply breaking force. It came to stop barely missing another vehicle parked in the driveway. I have no explanation for this dangerous episode. I had not used any type of automatic speed control. The car is serviced by authorized dealership: Hampton Chevrolet in Hampton VA. I was in the car with two of my grandaughters when the incident occurred. I was able to drive the car back without any problem, but I'm scared to drive it.

I was driving down the road at night and attempted a right hand turn when my power steering quit. The warning light on the dash came on. I almost got rear ended by cars coming from behind. I called the previous owner to see if they had ever had this happen. They stated it had happened once. They said they turned off the ignition and waited about 1/2 hour then cranked the car and the problem was solved. That’s what I did and it worked. Since this is an intermittent problem the service tech could not help.

All instruments failed. After a couple restarts they came back on. Lane departure alert doesn’t work now. From a web search, I’m afraid it’s just the beginning. No, I haven’t taken it to the dealer; they charge for diagnosis. And it hasn’t been inspected. The problem doesn’t act up all the time. There are no warning lights, the system just fails. I have 50,600 miles on it. If you find what I’ve found in my web search, the cost of repair is staggering, especially for retirees. I hope you look into Chevrolet’s problem they’ve been having with the Impala.

I parked my car at work and worked a full day Saturday the 13th of November. I go out to start my vehicle and 3 warnings appear all at once. Stabilitrak, ABS, and power steering. Reading online I’m not the only one but with only 109,xxx miles it’s kind of BS that there’s obviously an engineering flaw with these vehicles and I probably will give a few car payments worth to get this fixed. I’ve owned this vehicle since 17,xxx miles

After starting car (and sometimes put in reverse), steering appears locked and message says to get power steering serviced. After putting back in park, power steering starts working. This happened multiple times last few weeks. Took car in to Joe Johnson Chevorlet (Troy OH) for scheduled next morning service. After 2 full days of excusses why they couldn't get to our car, we picked it up and took it to independent service shop. He test drove it and steering was fine. Got car back and next day it happened multiple times again. Took it back to independent to run code, which did not give exact problem. Drove car 1 block and power steering went out turning. Then again 1 block later. It is now parked and afraid to drive it. Chevy seems not to want to work on it and independent does not know what is wrong, said it could take him up to a week to trouble shoot entire system. He hasn't got back to me yet. HELP! Also, parking brake seems to engage by itself overnight. When starting car, sometimes it is on. We never use it. This may be related.

While driving home from work on the highway, the power steering failed and the steering wheel became very physical to actuate. The DIC indicated the warning for power steering off. The failure occurred simultaneously with the warning indication with no prior warning. While driving at high speed, this failure could have caused a serious accident. The failure happened on the street as well. Both times while reaching destination the car was shut off and when restarted, the steering worked once again.
