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.

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.

I WAS DRIVING AND LADY CAME TO A COMPLETE STOP AT RAIL ROAD TRACK AND I COULDN'T STOP I RAN INTO THE BACK OF HER

7/28/2019

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.

VEHICLE SPEED CONTROL

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.

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

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?

When driving on the highway at full speed my car suddenly loses power almost causing me to be hit from behind. I then get a Reduced Engine Power warning. Once I get the car off the road, I shut the engine off for a few minutes and then restart it. The car runs fine but the check engine lights remains on. This has happen 4 times this week.

I noticed lately my car has trouble starting, especially after I get gas. Anywhere I take it, no one knows what it is. Literally someone said that I’m not holding the brake down when I’m starting it. 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!
