2018 Chevrolet Impala Other Problems

Your air conditioning system isn't working because the evaporator core is leaking. General Motors has a known issue (Special Coverage Adjustment #N182186881) for this exact problem affecting multiple 2018 Impalas, but GM has refused to cover the repair under this program based on your vehicle's VIN. The repair will likely involve replacing the evaporator core and recharging the air conditioning system.

Your 2018 Chevy Impala's AC evaporator core developed a leak and had to be replaced at the dealership. You noticed a coolant smell in the cabin but no warning lights. You believe your car qualifies for GM's Special Coverage N182186881 for evaporator core leaks, but GM has denied your claim without explanation. The repair may involve replacing the evaporator core with a new or upgraded unit to prevent future leaks.

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

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?

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! *TR

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

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.

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.

WHILE DRIVING ON HIGHWAY, WENT TO TOUCH THE HAZARD BUTTON BUT PUSHED THE ENGINE START/ STOP BUTTON INSTEAD. ENGINE SHUT OFF. HAD TO PULL OFF THE ROAD, ENGAGE BRAKE, PUT TRANSMISSION INTO PARK TO BE ABLE TO START CAR. THE HAZARD LIGHTS BUTTON IS WAAAYYY TO CLOSE TO THE START STOP BUTTON. ESPECIALLY WHILE KEEPING AN EYE ON THE ROAD. THIS IS A NEW RENTAL CAR BELONGING TO EAN HOLDINGS LLC.
