2015 CHEVROLET IMPALA Complaints

SIDE DETECTION MODULES ARE IN AN AREA, REAR BUMPER, WHERE MOISTURE CAN SATURATE THE SENSOR/MODULE WHICH THEN CAUSES A FAULT. THE DASH DISPLAY THEN BEGINS TO FLASH AND TURN OFF AND ON. GAS PEDAL CAN ALSO BE AFFECTED, WHERE YOU CANT CONTROL ACCELERATION. THIS HAPPENS WHEN VEHICLE IS STATIONARY AND IN MOTION.

I WAS DRIVING ON 2-LANE ROAD AND THE RIGHT SIDE DETECTION SYSTEM (SDS) INDICATOR LIGHT IN THE SIDE MIRROR CAME ON EVEN WHEN THERE WERE NO CARS OR OBJECTS NEXT TO ME. THE INDICATOR LIGHT WOULD NOT TURN OFF EVEN WHEN THE CAR WAS OFF AND PARKED. NO WARNING MESSAGES CAME UP WHEN THE CAR WAS STARTED. I TURNED THE SDS AND PARK ASSIST OFF IN SETTINGS, BUT THE LIGHT REMAINED ON. I REMOVED FUSE 62 (REAR CAMERA/PARK ASSIST/SIDE BLIND ZONE ALERT) IN THE ENGINE COMPARTMENT FUSE BLOCK TO GET THE LIGHT OFF. I REINSTALLED THE FUSE AND THE LIGHT REMAINED OFF UNTIL THE NEXT TIME I STARTED THE CAR AND IT TURNED BACK ON AND STAYED ON. A FEW DAYS LATER I GOT A WARNING MESSAGE TO SERVICE THE SDS WHEN I STARTED MY CAR. THE BLIND ZONE ALERT SYSTEM INDICATOR LIGHTS DID NOT COME ON AND THE SYSTEM DID NOT WORK AT ALL EVEN WHEN VEHICLES WERE IN MY BLIND SPOT ON THE LEFT OR RIGHT SIDE OF MY CAR. I RECEIVED 3 WARNING MESSAGES WHEN I STARTED MY CAR. THEY SAID TO SERVICE FRONT CAMERA, PARK ASSIST AND SDS. FUSE 62 WAS BLOWN. I REPLACED THE FUSE AND IT IMMEDIATELY BLEW AGAIN. NONE OF THE DRIVER ASSIST SYSTEMS WORKED INCLUDING THE SIDE BLIND ZONE ALERT, LANE DEPARTURE WARNING, FORWARD COLLISION ALERT SYSTEM, PARK ASSIST AND REAR CROSS-TRAFFIC ALERT. I TOOK MY CAR TO LAKE GENEVA CHEVROLET DEALERSHIP. THEY DIAGNOSED THE PROBLEM, WHICH REQUIRED REMOVING THE REAR BUMPER TO CHECK THE 2 SBZA MODULES MOUNTED ON THE INSIDE CORNERS OF THE BUMPER. THEY DISCOVERED CORROSION IN BOTH MODULES DUE TO WATER INTRUSION, WHICH SHORTED OUT THE ELECTRONICS. THEY SAID IT WAS CAUSED BY WATER ON THE MODULE SEAM GETTING INTO IT BY FREEZE THAW. THEY HAD TO REPLACE BOTH MODULES FOR A TOTAL COST INCLUDING LABOR OF $1172. THEY STATED THAT IT WILL HAPPEN AGAIN SINCE IT IS THE SAME MODULE DESIGN AND DUE TO THE MOUNTING LOCATION. CHEVY HAS KNOW ABOUT THIS SINCE BEFORE 5-2017 WHEN THEY ISSUED TSB# 17-NA-154 ABOUT EXACT PROBLEM.

SIDE BLIND ZONE MONITORING SYSTEM FAILURE. AT APPROXIMATELY 40,000 MILES PASSENGER SIDE SBZM LIGHT WAS CONSISTENTLY ON THEN SYSTEM FAILED. AT APPROXIMATELY 47,000 MILES DRIVER SIDE LIGHT IS CONSISTENTLY ON. SEEMS TO BE A VERY COMMON ISSUE ON THESE CARS

STARTED WITH SIDE DETECTION LIGHT NOT GOING OFF. THEN SERVICE FOR SIDE DETECTION CAME ON. WITHIN A WEEK I HAD MULTIPLE ERRORS AND SERVICES SUCH AS REAR CAMERA, FRONT CAMERA, COLLISON PREP, PARK ASSIST. REPLACED FUSES EVEN THOUGH NOTHING WAS WRONG WITH THEM. SAME LIGHTS. AS THE DAYS GO ON... I AM EXPERIENCING TROUBLES WITH CAR STARTING HAVING TO MANUALLY START/INSERT FOB INTO CENTER CONSOLE. HEATING AND ELECTRICAL INSIDE CAR NOT WORKING, STOPPED IN MIDDLE OF DRIVING AND IT WAS FOGGY AND OBVIOUSLY I COULDN'T DEFROST MY WINDOWS. RESTARTED CAR NUMEROUS TIMES AND THEN HEAT POPPED BACK ON. ALSO IN THE MIDDLE OF DRIVING IT STATES KEY FOB NOT DETECTED AND IT'S LITERALLY IN THE CUP HOLDER. I HAVE CHANGED THE BATTERY RECENTLY AT THE DEALER SO IT IS NOT A FAULTY FOB OR BATTERY. MY TRUNK HAS BEEN JUST POPPING OPEN FOR NO REASON AND SEVERAL TIMES WHILE I WAS DRIVING BUT ALSO WHILE STATIONARY. FOR SOME REASON MY POWER STEERING IS NOW ACTING LIKE IT IS OUT OF FLUID AND GRINDING HOWEVER ALL FLUID IS FULL. IT SEEMS TO BE ALL ELECTRICAL AND VERY SCARY AND UNPREDICTABLE.

TL* THE CONTACT OWNS A 2015 CHEVROLET IMPALA. WHILE DRIVING 50 MPH, THERE WAS AN ABNORMAL ODOR OF BURNING BRAKE PADS. ON SEVERAL OCCASIONS, THE PARKING BRAKE ENGAGED INDEPENDENTLY AND, SOMETIMES, TOOK AN EXTENDED AMOUNT OF TIME TO DISENGAGE. THE VEHICLE WAS TAKEN TO ATHENS CHEVROLET (LOCATED AT 4110 ATLANTA HWY, ATHENS, GA 30606, (706) 549-3512). THE CONTACT WAS INFORMED THAT THE VEHICLE WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 14V541000 (PARKING BRAKE). THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE APPROXIMATE FAILURE MILEAGE WAS 71,000.

MY SIDE DETECTION WARNING LIGHT CAME ON AND WOULD NOT SHUT OFF, I TURNED MY CAR OFF AND STILL IT WAS ON, UNTIL WHAT SEEMED LIKE THE LIGHTS BURNED OUT IN MY READ VIEW MIRRORS. THE WARNING COMES UP ON MY DASH REPEATEDLY. I JUST RECEIVED A BID TO HAVE IT FIXED, $1200. 00 AND ITS PARTS ARE BACK ORDERED FROM CHEVY. SEEMS PEOPLE EVERYWHERE ARE HAVING THIS PROBLEM ONLINE. I CALLED CHEVY, THEY SAID NO RECALL UNTIL THERE IS A "SAFETY CONCERN", NOT COVERED UNLESS YOU ARE UNDER YOU 36K MILES. I AM NOT, SUPER FRUSTRATING TO PAY THAT MUCH TO HAVE A "CONVENIENCE" FEATURE FIXED.

4-4-2019 DROVE TO WORK. NOTICED AFTER PARKING CAR THAT THE SIDE BLIND SPOT WARNING SYSTEM LIGHT WAS "ON": TURNED CAR ON AND THEN OFF, BUT IT STILL STAYS LIT. THIS WILL RESULT IN THE CAR BATTERY BEING DRAINED, ELECTRICAL SYSTEM BEING FRIED, OR THE SENSOR EVENTUALLY BURNING OUT. NOT SURE WHICH

I STARTED MY VEHICLE AND INSTANTLY THE PASSENGER SIDE BLIND SPOT INDICATOR LIGHT CAME ON. EVEN AFTER I SHUT OFF MY VEHICLE; THE INDICATOR LIGHT STAYED ON. IT WOULD CHANGE IN BRIGHTNESS OCCASSIONALLY. I WAS HOPING THAT IT WOULD NOT DRAIN MY BATTERY OVER NIGHT AS I'M NOT A MECHANIC. I CHECKED THE SENSORS ON THE BUMPER FOR CLEANLINESS.

BLIND SPOT DETECTION HAS FAILED AGAIN. SERVICE SIDE DETECTION ERROR IN DASH DISPLAY THE SYSTEM FAILED UNDER WARRANT IT HAS FAILED AGAIN OUT OF WARRANTY. THIS IS A SAFETY CONCERN CHEVY NEEDS TO FIX.

THE BLIND SPOT ALERT QUIT WORKING AT 48000 MILES. DEALER QUOTED $1000 TO REPAIR. MANY IMPALA OWNERS ARE HAVING THIS PROBLEM. APPEARS TO BE A PROBLEM WITH LOCATION AND DESIGN OF THE SENSORS.WATER AND SNOW CAN CONTAMINATE THE SENSORS AND CAUSE THEM TO FAIL. GM NEEDS TO PROVIDE WARRANTY RELIEF BECAUSE OF A POOR DESIGN.
