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. *1 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.

REFRIGERANT LEAKS. 1234YF

May 13, 2021

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.

POWER TRAIN

5 complaints

The contact owns a 2018 Chevrolet Malibu. The contact stated that while driving at various speeds, the vehicle hesitated or jerked while depressing the accelerator pedal, with an abnormal humming sound coming from the vehicle. The contact stated that the check engine warning light was illuminated. Additionally, the contact stated that while in reverse(R), the vehicle failed to accelerate while depressing the accelerator pedal. The vehicle was taken to an independent mechanic where the vehicle was diagnosed with transmission failure. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The vehicle remained with the independent mechanic unrepaired. The failure mileage was approximately 128,000.

Feb 24, 2025

Since vehicle purchase in 2018 there is a shifting problem with the transmission. I have paid for shifter repairs and still the problem exist. While driving the car gets stuck in gear and hard to accelerate. The issue happens at various times without warning. There has been two instances that could have led to potential accidents. Upon spraking with and researching other impala owners, this is a common problem in the 3.6 engine Chevrolet Impalas but nothing has been done. The dealer has a plan to determine but it has always cost $1500+ to the customer.

Oct 01, 2024

While driving or idling (car in D/M, both automatic and manual), the car will rapidly shift to park and then back to where the shifter was set, usually in a lower gear that slows the car down or prevents acceleration. The transmission or speed sensor could be an issue. This can happen in rapid succession 3-5+ times in a row, which has led to a drop in speed from 65 MPH to 40 MPH, especially dangerous at faster speeds on a highway or when deceleration is occurring more quickly, like going up a steep hill. I am unsure what indication there is for cars that are behind me, but they have had to slow down or pass me in some instances to avoid hitting me. If it happens while turning at a 2 way stop or on an entrance ramp, my car might not accelerate fast enough to merge into traffic. There have been no lights on the dash, and the dealer has not been able to identify the issue when I have taken it in.

Jun 08, 2023

I have a 2018 Chevrolet Premier Impala that has started skipping gears at 1st and 2nd while driving. The vehicle shudders when it changes gears. Took vehicle to dealer who informed me that the transmission needs to be replaced already. I haven't received any dash messages or vehicle warnings prior to noticing the transmission problem. I always kept the car properly serviced by the dealer for all routine maintenance requirements. I am the original owner of this vehicle. The car has under 100,000 miles. Dealer informs me that it will take at least a week before they can possibly get new transmission for vehicle. I may be without vehicle for at least 2 weeks minimum.

TRANSMISSION SLIPPING, ROUGH SHIFT AND BUCKING BACK AND FORTH. HAPPENS INTERMITTENTLY AT LOW SPEEDS AND IN STOP AND GO TRAFFIC AS WELL AS HIGHWAY SPEEDS AND WHEN PASSING.

Sep 27, 2019

THIS WAS A HERTZ RENTAL CAR I PICKED UP AT THE ORLANDO, FL AIRPORT. JUNE 2, 2019. THERE WAS NO OPERATORS MANUAL IN THE CAR. IT WAS 10 PM AND I HAD TO DRIVE 90 MILES TO MY DESTINATION. ABOUT 30 MINUTES ON THE HIGHWAY TO CHECK OIL LIGHT CAME ON. I TRIED TO CLEAR THE NOTICE BY PRESSING SEVERAL BUTTONS ON THE DASH BOARD. THEN I THOUGHT I FOUND THE CORRECT BUTTON AND PRESSED IT. IT WAS THE CAR START AND OFF BUTTON. THE CAR IMMEDIATELY SHUT OFF INCLUDING ALL THE LIGHTS. O WAS GOING 65 MPH AND SUDDENLY THE ROAD WAS PITCH BLACK. THE ENGINE HAD TURNED OFF SO I COULD NOT HOLD MY SPEED. I SLOWLY PULLED OVER TO THE SIDE. (TURN SIGNALS WERE NOT WORKING AT THIS TIME). WHEN I COMPOSED MYSELF, I PUT THE CAR IN PARK AND RESTARTED IT. THANKFULLY THERE WERE NO OTHER CARS AROUND SINCE THE CAR WAS TOTALLY DARK AND WITHOUT POWER AT 65 MPH. I WAS VERY FORTUNATE. I AN BAFFLED THAT CHEVROLET WOULD NOT HAVE CAUGHT THIS FLAW BEFORE PUTTING THESE CARS ON THE ROAD.

OCTOBER 10TH, I WAS IN AN ACCIDENT WHERE I WAS LITERALLY AN ENTIRE CAR LENGTH BACK DRIVING WITH THE FLOW OF TRAFFIC AT 50-55 MPH, WHEN THE VEHICLE IN FRONT OF ME CAME TO AN ABRUPT STOP ON THE FREEWAY. I SLAMMED ON MY BRAKES BUT MY CAR SLID STRAIGHT INTO THE BACK OF THE VEHICLE IN FRONT OF ME. IT FELT AS IF MY BRAKES WERE NOT STOPPING MY CAR. I NOTICED THIS HAPPENING BEFORE ON A MAIN STREET AND I WAS TRAVELLING AT 45 MPH BUT I DID NOT THINK ANYTHING OF IT AT THE TIME.

IN FEBRUARY 2019 I PURCHASED A 2018 CHEVY IMPALA PREMIER, UPON DRIVING THE CAR I NOTICED THAT THE BRAKES WERE NOT WORKING LIKE MY 2018 CHEVY CAMARO BUT I CHUCKED IT UP TO THE CAR BEING HEAVIER AND PAID IT NO ATTENTION. FOR MONTHS I HAVE BEEN THINKING THAT MAYBE I JUST NEED TO GET USED TO THE BRAKES ON MY NEW CAR AND THAT IT WAS NOTHING. WHILE I DRIVE AT NORMAL SPEEDS (40 - 45 MPH) MY CAR SLID AN EXTRA 5- 10 FT MORE THEN IT IS SUPPOSED TO EVERY TIME. YESTERDAY WHILE BRAKING MY BRAKES JUST TOTALLY DID NOT RESPOND CAUSING ME TO HIT THE BACK OF ANOTHER DRIVER. I WAS DRIVING ABOUT 30 MPH LITERALLY JUST TURNING OUT OF A SHOPPING PLAZA WHEN THE ACCIDENT HAPPENED. I STARTED TO PRESS THE BRAKES ABOUT 50 METERS AHEAD AND MY CAR DID NOT BUDGE NOR DID IT BEGIN TO STOP IT CONTINUED TO DRIVE AT THE SAME SPEED UNTIL I PROMPTED TO TURN AND BRACED FOR THE COLLISION. I HIT THE BACK PASSENGER BUMPER AND THE SIDEWALK BRINGING MY CAR TO A HALT. THIS INCIDENT WHICH PROMPTED ME TO LOOK FURTHER BRUNG ME ONLINE TO SEE THAT THERE IS A RECALL FOR THE CHEVY IMPALA BRAKES WORKING IMPROPERLY. IT SAYS THAT IT IS ON SOME IMPALAS AND I BELIEVE THAT MINE IS ONE OF THEM.

1 complaint

Passenger side front seat. When occupied, airbag sensor located inside the seat is malfunctioning. My husbands safety is at risk when he's in the car. He tries moving the seat up, back, etc. Sometimes works and the airbag sensor works. We are fearing that if there were any accident or need, that his life would be in danger if the airbag didn't deploy. This shouldn't be at the consumers expense as this is a safety issue. This has been ongoing for over 6 months.

I was sold a used car w/ undisclosed accidents. Had many issues within first few weeks. Had transmission cooler lines replaced after they burst. Radiator, compressor, condenser, and much more. Then the Airbag light came on. Dealership said connectors were bad. Fixed it. Light came on again.took it in to dealership. They had it for over two weeks. The GM for all the dealerships Told me the vehicle was not unsafe and told me lies. But the service girl confessed she no longer had access to my vehicle or my file and her boss and the Gm had taken over working on it. She then told me they pulled Ford model air bags from my Chevy Impala. Now the light has come on again. I do not feel safe or rust the dealership to fix it properly.

I KNOW HOW TO START MY VEHICLE! It doesn’t want to start and sounds like a broke down Saturn when I start it. It takes like 20-30 seconds to start. ALSO that AC went out, I paid $700 AT Chevy, and then the AC went out again a few months later, again no one knows why. WTF!

I PURCHASED THIS VEHICLE 2 WEEKS AGO NEVER BEEN HAPPIER. MY COMPLAINT IS ABOUT MY HEADLIGHTS THEY HAVE SERIOUS CONDENSATION IN BOTH AND THERE IS ABOUT AN INCH OR 2 OF WATER INSIDE THE HEADLIGHTS. THIS ISSUE IS CAUSING BAD VISIBILITY WITH LOW LIGHTING. I HAVE TRIED EVERYTHING TO KEEP THE WATER OUT AND PROVIDE HEADLIGHTS WITH PROPER AIR SO THIS DOESN'T HAPPEN. HOW COME CHEVROLET DIDN'T RECALL THESE HEADLIGHTS DUE TO POOR DESIGN AND IMPROPER VENTILATION. WHAT CAN I DO BESIDES SPEND $200.00 ON 2 NEW ONES?

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. *TR

VEHICLE SPEED CONTROL,UNKNOWN OR OTHER

1 complaint

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.
