2016 Chevrolet Impala

WHILE DRIVING DOWN THE HIGHWAY A LOUD EXPLOSION MADE MY PASSENGER'S AND ME GET STARTLED FOLLOWED BY A RINGING IN OUR EARS. IT CROSSED MY MIND THAT THE VEHICLE WAS GETTING SHOT AT. UPON INSPECTION THERE WAS NO INTERIOR DAMAGE, HOWEVER WHILE INSPECTING THE OUTSIDE OF THE VEHICLE THERE WAS DAMAGE ON THE SUNROOF OF THE VEHICLE. THE SUNROOF HAD SHATTERED IN AN UPWARDS POSITION AS IF IT HAS EXPLODED OR DAMAGE CAME FROM THE INSIDE OUT. CLOSER EXAMINATION DID NOT PROVIDE A REASON OR FOREIGN OBJECT THAT COULD HAD CREATED THE DAMAGE. IT WAS VERY DANGEROUS TO HAVE THIS HAPPEN WHILE DRIVING AND/OR WITH THE POSSIBILITY OF EYES TO FALL ON ANY OF THE PASSENGERS OF THE VEHICLE.

THE LEFT SIDE (RADIATOR SIDE) CATALYTIC CONVERTER DEVELOPS HAIRLINE CRACKS AND EVENTUALLY BREAKS FROM THE FLANGE ATTACHED TO THE ENGINE. IF IT BREAKS, IT FALLS FORWARD AND GETS CAUGHT IN THE FAN, POSSIBLY CAUSING FURTHER DAMAGE. APPEARS THAT CRACKS DEVELOP DUE TO LACK OF STRENGTH FROM THIN METAL AND POSSIBLE STRESS OF WEIGHT AT GIVEN POINT, WHICH IF UNNOTICED, THE CONVERTER WILL BREAK.

1. THE DISPLAY SCREEN WENT BLACK WHILE DRIVING USING NAVIGATION. THE FAULT WAS A DEFECTIVE HMI MODULE, GM PART # 84296482 AT A COST OF $1100 (SEE ATTACHED DOCUMENT). THE SUDDEN LOSS OF THE SCREEN WAS DISCONCERTING AND COULD HAVE CAUSED AN ACCIDENT. THIS SHOULD LEAD TO A RECALL AND REIMBURSEMENT OF THE REPAIR COST. 2. WHEN THE ADAPTIVE CRUISE CONTROL (ACC) CAUSES THE BRAKES TO BE APPLIED IT DOES SO VERY SUDDENLY AND IN THE ABS "CHATTERING" MODE EVEN WHEN THERE IS NO COLLISION DANGER. THIS PRODUCES A JOLT TO THE DRIVERS AND OCCUPANTS WHICH IS AN UNEXPECTED AND UNSAFE RESPONSE.

I BOUGHT THE CAR BRAND NEW, AND NOW IT HAS JUST OVER 24,400 MILES ON IT AND I HAVE ALREADY HAD TO REPLACE THE FUEL PUMP AND FUEL RAILS ON THE CAR 4 TIMES. LAST TIME WAS JUST DRIVING STRAIGHT DOWN THE HIGHWAY AND UP AND DIED COMPLETELY, CAR WOULD THEN TURN OVER BUT NOT FIRE, SO WAS STRANDED ALONG SIDE THE HIGHWAY WAITING FOR A TOW TRUCK TO COME OUT. I HAD IT REPLACED THE FIRST TIME AT 9991 MILES ON 12-14-17, THEN AGAIN AT 20798 MILES ON 11-20-19, THEN 21074 ON 2-15-20, THEN AT 24111 ON 9-9-20. YES I KNOW IT IS UNDER WARRANTEE AT THIS TIME, BUT GETTING REALLY ANNOYING NOT BEING ABLE TO TRUST THAT NEW OF A VEHICLE TO GO ANY DISTANCE AND NOT KNOWING IF WILL LEAVE SIT STRANDED ALONG SIDE THE ROAD WAITING FOR A TOW AGAIN OR NOT. I HAVE EMAILED THE DEALERSHIP AND THE ARE EMAILING ME A COPY OF ALL THE PAPERWORK, JUST HAVEN'T RECEIVED IT FROM THEM YET TO ATTACH IT, BUT THE HAVE IT ALL AT SCHWIETERS CHEVROLET OF WILLMAR.

MY VEHICLE TURNED OFF SEVERAL DIFFERENT OCCASIONS ONCE AS I WAS DRIVING FREEWAY SPEED APPROXIMATELY 60-65MPH ENGINE COMPLETELY SHUT OFF I ATTEMPTED TO PUT IN NATURAL AND RE START THE IGNITION AS THE VEHICLE WAS STILL MOVING WITH NO POWER VEHICLE DID NOT START I MERGED TO THE SIDE OF THE HIGHWAY BREAKED TO STOP AND PLACED THE GEAR SHIFT ON PARK AND TRIED TURNING THE IGNITION ON AND STILL DID NOT TURN ON A FEW ATTEMPTS LATER CAR STARTED. ANOTHER INCIDENT I WAS DRIVING CAME TO A RED LIGHT AS I WAS WAITING FOR MY GREEN LIGHT MY CAR SHUT OFF WHILE I HAD MY FOOT ON THE BREAK I PUT THE SHIFT GEAR I TO PARK TURNED THE IGNITION ON AND CAR STARTED

WHILE DRIVING VEHICLE AT A LOW SPEED SOON AFTER STARTING, A SERVICE WARNING " SERVICE POWERSTEERING DRIVE WITH CARE" APPEARED ON THR DIC. VEHICLE BECAME EXTREMELY HARD TO STEER BUT I WAS ABLE TO MANEUVER IT TO A SAFE LOCATION PUTTING A LOT OF PHYSICAL PRESSURE ON THR STEERING WHEEL. SWITCHED CAR ON AND OFF SEVERAL TIMES AND WARNING STILL APPEARED. AFTER REMOVING KEY FROM IGNITION AND SPENDING APPROXIMATELY 20 MINUTES ATTEMPTING TO TROUBLESHOOT, RESTARTED VEHICLE AND WARNING REMOVED AND WAS ABLE TO STEER AGAIN. WOULD'VE BEEN A VERY NASTY SITUATION FOR A NOVICE DRIVER OR ON A BUSIER AND CURVIER ROADWAY.
