answers to Questions from above 1. EVAPORATOR KIT 84409864 2. Not a safety issue to my knowledge. 3. Yes, issue was diagnosed and repaired at dealership. (Receipt for work - including part numbers will be attached with supporting documents) 4. No, no one outside of the dealership. 5. No warning lights but there was the smell of coolant in the cab of the car. Due to an issue with my 2018 Chevy Impala - V6 engine, I had to have the AC evaporator core replaced due to a leak (faulty part). Searching the NHTSA website, I found the below special coverage which seems to match my vehicle perfectly including the issue for which the special coverage was issued. I filed a claim with GM but continue to be told that my vehicle is not covered by this but no reason as to why it isn't covered. *Special Coverage N182186881 - Evaporator Core Icing, Leak *Quantity Part Name Part No. EVAPORATOR KIT 84409864 This is concerning as a consumer as the issue and vehicle description matches the special coverage exactly, yet GM is stating that my vehicle is not covered. This issue clearly extends beyond the number of vehicles affected that was reported. Also, being replaced with the same part (part num) does give me pause that this will be an issue again in the future, costing consumers even more money and time.

The Evaporator core is leaking and a/c system is not operative. There is an outstanding report from your office, DCS4922, that outlines this condition perfectly. This report talks about a Special Coverage Adjustment #N182186881 Evaporator Core Icing, Leak, and an estimated number of vehicles involved. Since it is an estimated number of vehicles it means that GM doesn't know exactly how many vehicles are involved. It is my position that my vehicle should be included in the Service Adjustment. General Motors will not consider repair based on my VIN. This Special coverage addresses the exact issue I am experiencing. I have visited a Chevy Impala public forum and found there are others experiencing the same issue. Any help will be appreciated.

Ii purchased the car new. at 3 years and 3 months the evaporator core failed dumping the Freon. I realize you stated the A/C is not a safety item but I read many complaint on this vehicle on the internet. I am a retired mechanic and the failure rate for evaporators is very low. I changed out maybe 10 in 30 years working on vehicles. This needs to be looked into and addressed by GM and corrected. Any help would be greatly appreciated.

The evap core started leaking a month ago had the car for 2 years and as I read online its a common issue and Chevy doesnt want to fix it. Sometimes the transmission shifts hard but doesnt happen often

- Temple City, CA, USA

Getting a second look at air conditioning. I was told the compressor could be leaking as there has been no freon for over a month or two. The freon is 120/pound and could cost 1000, he mentioned for freon alone. This is a 2018, purchased last year and I'm dealing with a compressor issue as well as very expensive freon?

On 16th July 2020 while driving bell sounds went off in my car, on dash airbag warning came on and got an onstar alert that airbag malfunction. Onstar said to get it to dealership asap. Yesterday 20th July dealership told me that front passenger seat airbag module, front passenger airbag plate in seat and something else airbag is wrong. Told me not covered under warranty in which since it is a 2018 I couldn't believe it. They said because have 62,000 miles is why. I said this is a safety issue they acknowledged that but said I would need to have it repaired which would cost $1300 without taxes. I called General Motors and have a case number. However, not GM nor the dealership nesmith Chevrolet, Buick, GMC seem to feel this should be a recall or a safety issue that they should be liable for!

My vehicle has been serviced several times since I have purchased the vehicle. The car will completely shut off when attempting to turn back on after the auto stop turns it off then I have to place the park hit the start switch and restart the vehicle. Also my ac has stopped several times in the vehicle. The ac compressor was replaced in 2019 and had been serviced twice before that happened because it blows extremely low and have to put it on high just for the air to blow. As of today the ac has been going in and out even after the replacement of the compressor and still no one can tell me what's the issue!

While operating vehicle on public roadway while utilizing the ac function, the ac evaporator catastrophically failed under the dash, startling the driver & passenger, and exposing them to high levels of 1234yf refrigerant in the enclosed cabin. The ac system subsequently went into low pressure mode, rendering all ac functions useless such as defrosting the windshield which has created safety issues in addition to the inhalation of the leaked refrigerant. This style of failure is covered under special coverage adjustment - N182186881 evaporator core icing, leak for certain 2016-2018 Impala vehicles. GM customer service states that this VIN is not covered under this special coverage, even though this is a similar failure on a part that should last the life of the vehicle. GM refuses to cover this failure and requested that the customer contact the NHTSA to help resolve the missing VIN from the special coverage. Customer is currently saddled with a $2300 repair bill for a lifetime part that has failed in 2.4 years and poses an ongoing safety issue.

From December 22 thru 27, 2018 I rented this 2018 Chevrolet Impala (California plate 8dve598) from hertz at the hotel del coronado, coronado, ca. For the first 4 or 5 backups the reverse camera display worked properly. That is it came on when I shifted into reverse and went off when I shifted forward. Then suddenly it stayed on for the rest of the week. We could neither get it to go to the normal icon display nor turn it off. It would not reboot when the ignition was turned off. Safety consequence--at night the display is so bright that it completely blocks right front quarter vision. I had to drive this to 4,000 feet at night on a California mountainside. We mitigated the problem by folding one of the very large aaa city series maps with all its weight wedged against the base of the windshield and one thickness over the display. This would not have worked if I had had to run the defroster. NHTSA needs to mandate either a pull down cover for these dlsplays or a panic button to shut them off. Thank you.

Adaptive cruise control (acc) issues scenario 1 first day I was traveling at approximately 70 mph. As I would in any of my other 100 + cars I've owned, I held the cruise control 'set' button expecting the speed to gradually decrease. The Impala much to my surprise, with traffic behind me, went from 70 mph to approximately 20 mph within 7 secs. The traffic behind me was swerving to avoid crashing into me. It clearly states on page 182 of the owner's manual 'reducing speed while acc is at a set speed. 'press and hold setuntil the desired lower speed is reached, then release it. When you hold the set button the speed drops so rapidly there is no possible way you could reduce the speed to only (for example) to 58 mph. Scenario 2 I was following a vehicle with the acc set. Vehicle ahead of me signaled to make a right turn and was merging right to make the turn. As I proceeded to change lanes and go around the vehicle, my Impala slammed on the brakes causing the vehicle behind me to have to swerve to avoid a crash. Scenario 3 referring to the scenerio 2. when the vehicle turning right cleared the camera on my Impala the Impala accelerated aggressively as though I was attempting to pass someone. It was very unexpected and to the point where I felt I could lose control of the vehicle. Scenario 4 when rounding a curve if the acc camera senses a vehicle moving in a parking lot near the road it again brakes harshly for no good reason. Again causing the vehicles behind me to have to react. The Impala will again accelerate aggressively once past the moving car in the parking lot. Scenario 5 in two lane traffic with the acc set, when you're rounding a corner if the camera of the acc gets the car in the other lane in its vision the Impala will again slam on the brakes. When the car in the other lane is out of the camera range the Impala accelerates rapidly.

The forward collision alert system which is stated to work over 40 mph does not give adequate warning at any setting. The system shows a green icon when following another vehicle. The icon changes to amber when following another vehicle extremely close (way too close) as a tailgating alert. It is meant to give a heads ups flashing red display on the windshield when overtaking another vehicle at a speed that may cause a collision. This system has a near. A medium and a far setting which is supposed to function within 194 ft. At no setting approaching a vehicle from the rear to a dangerously close point could I get the system to give a red alert, this was on the far setting. The dealer service checked the system in the garage and said it was working. They would not do a road check because it is too dangerous. The service manager said he had done them in the past and the red alert only happens when you are extremely close to the car ahead. In a controlled check I got to within a cars length overtaking the car ahead with no alert and this was on the far setting. This system is useless without giving an alert in time to react. I have seen this system work well in other brand cars.

I owned a new 2014 Chevrolet Impala. The 2014 Impala had a backup camera system which was outstanding. I never had a problem with what I saw on the rear view monitor screen which was on the dash of the Impala. I traded in the 2014 Chevrolet Impala for a 2018 and now there are two major problems with the 2018 Impala back up camera system. First, if there is a light rain to a heavy rain you lose 80% to 90% of the clear vision on the monitor screen. Not once did I ever have a problem with my 2014 Impala. Second, I have lost 20% of my rear view vision because 20% of the monitor screen shows the rear view bumper which reflects the sky. These are two major safety defects with my 2018 Impala. Not once did I ever have a problem with my 2014 Chevrolet Impala. I have attached to iphone photos to illustrate the safety defects. I will put today's date to go to next part of form. Problem started when I first got the car. I was told that the camera on the back of the car was relocated as compared to the 2014 Chevrolet Impala camera location.
