Blind side collision monitor is not functioning properly due to faulty design which allows moisture to get into cabin where the monitor is installed. Causing the collision feature not to function properly and "service side collision" msg to show on the dashboard. I had this issue before and had it repaired by the dealer on 03/2019. The problem has since returned. But this time it's caused the functions on the dashboard ( gas, h/c and speed meters, digital monitor screen etc) to stop working where I can't tell if I have gas or my driving speed or anything associated with the dashboard info system, it blacks out. And now the alert light on the door mirrors continuously stay on even when there's no car on the side of my vehicle and even when the car is turned off. I took it back to the dealership and have been told that the collision monitor sensors AGAIN need to be replaced.

The connector on the drivers side module is corroded from water intrusion. It is an identical condition as described in NHTSA recall N172097060. The dealer and GM claims this vehicle was not included in the recall, even though it is a 2015 Chevrolet Impala. They now want me to pay 1,000+ dollars to fix the issue according to the steps in the bulletin? If i don't get this fixed soon is it could disable my vehicle as explained in the bulletin. I purchase the car in November of 2019 which is 7 months after this bulletin was released, and because GM did not include the VIN number in their system it was never corrected previously. The connector in the images is damaged now because the mechanic broke it at the dealer trying to get it off from the internal corrosion. I also contacted GM directly and they said that my car was not included in the VIN range and that I could take the issue up with NHTSA at my own prerogative.

My left hand (front bank) catalytic converter near the cylinder head fell off yesterday at the mounting flange. It landed in/on my fan. I went online to find a replacement part and found GM service bulletin PIP5419a & b first issued in 2016.. That bulletin explains a known "defect" with the weld. The catalytic converter pipe cracks at the mounting weld. the TSB was issued for all Impalas from 2014-2016, all VINS all transmissions, all 3.6l RPO LFX engines. It says that GM is working on a solution for this concern. Why isn't there a recall on this defect? The file I've attached is not from my car but from the TSB. It's very similar to what my cars catalytic converter looks like.

The blind sensor indicators are defective. The right side stays on but the the left side worked accordingly. Without warning the indicator on the left also stopped working. GM is well aware of the issue but will only fix the issue if it happens within a warranty timeframe. The initial issue with mine happened while driving in a winter storm with slushy roads. The sensors that stays illuminated isn't as much as a safety issue as the one that was lighting up as expected then stopped without warning. This item should be a full recall not a fix it if it breaks scenario. Mine stopped working within my warranty timeframe but because I was a secondary purchaser, I had no way of knowing that waiting until my next oil change would cause me to be stuck with $800 in repairs because GM refused to recall a safety issue item they are well aware of.

JUST RECEIVED A MESSAGE ON THE DRIVER INFORMATION CENTER THAT SAYS "SIDE DETECTION SYSTEM" SO I LOOKED IT UP IN THE WARRANTY INFO BOOK AND FOUND ONLY AN INSTRUCTION THAT SAID TO CLEAN THE REAR BUMPERS, AND NOTHING ELSE. CALLED DEALER AND THEY WANT $135 TO DIAGNOSE AND POSSIBLE REPAIR CHARGE OF $1100. LOOKED INTO COMMON PROBLEMS WITH OTHERS VEHICLE OWNERS AND FOUND SEVERAL WITH IDENTICAL PROBLEMS; ALSO FOUND A GM 'SPECIAL COVERAGE ADJUSTMENT"" DATED 4-1-19 COVERING THE COST OF REPAIR BUT ALSO FOUND IT WAS ONLY GOOD FOR YEARS AND/OR 80,000 MILES. MY VEHICLE HAS 62,000 MILES BUT IS 6 MONTHS BEYOND THE YEARS. IS THIS NOT A SAFETY ISSUE? I WOULD THINK SO. SO WHAT CAN I DO ABOUT THIS, AS I UNDERSTAND IT CAN CAUSE SIGNIFICANT OTHER INCIDENTS WITH THE VEHICLE, SUCH AS LOOSING THE INSTRUMENT PANEL INDICATORS AS WELL AS ISSUES INVOLVING VEHICLE HEADLIGHT AND ENGINE SHUT DOWN. WOULD LIKE A RESPONSE AS SOON AS POSSIBLE AS I WOULD LIKE TO GET THIS TAKEN CARE OF ASAP. THANK YOU [XXX] CELL # [XXX] JUNE 15. 2021 P.S. THIS HAS BEEN THE BEST VEHICLE I HAVE EVER OWNED; UP UNTIL NOW. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

MY CAR WAS REPAIRED UNDER SPECIAL COVERAGE N172097060, SIDE BLIND SIDE ALERT MODULE, IN APRIL 2019. TWO YEARS LATER THE SAME PROBLEM HAS RECURRED YET NOW I'M TOLD THE SPECIAL COVERAGE HAS EXPIRED, AS THE IN SERVICE DATE OF MY VEHICLE IS 2 MONTHS PAST THE 6 YEAR LIMIT. THE REPLACEMENT PART WAS ALSO SUBSTANDARD, PERHAPS EVEN THE ORIGINAL DESIGN, AS IT DID NOT LAST MUCH MORE THAN TWO YEARS. THE FACT THAT IT FAILED JUST TWO MONTHS AFTER THE COVERAGE LIMIT IS A SLAP IN THE FACE TO ME AS A CONSUMER. THE DEALER CHARGED ME OVER 900 DOLLARS TO REPLACE THE SIDE DETECTION SYSTEM, REQUIRED TO PASS NY STATE INSPECTION.

WENT TO PICK MY DAUGHTER UP FROM SCHOOL. CAME BACK AND PARKED MY CAR AS USUAL. WHEN I ATTEMPTED TO RESTART MY CAR THE ENGINE RULED UP AND THE CAR WOULD BARELY MOVE. UPON FURTHER INVESTIGATION, I OBSERVED THE VEHICLE MOTOR NOTIFICATION LIGHT ON AS WELL AS THE PARKING BRAKE NOTIFICATION WITH A TOOL ( WRENCH) UNDERNEATH. I ATTEMPTED TO DISENGAGE THE BRAKE AND IT SAID THE BRAKES HAVE BEEN RELEASED. HOWEVER, THE BRAKE NOTIFICATION SIGNAL IS STILL FLASHING AND THE VEHICLE SEEMS TO BE DRIVING LIKE THE BRAKES ARE STILL ENGAGED.

I HAD THE DRIVER SIDE BLIND SPOT DETECTION GO BAD ON MY IMPALA, SO IT'S STARTING OUT THAT MY DRIVER SIDE MIRROR BLIND SIDE IMAGE WAS BLINKING, THEN IT STOP AND WAS WORKING OK FOR ABOUT THREE WEEKS AND THEN A MESSAGE APPEARS ON MY DASH TO FIX THE BLIND SPOT DETECTION SYSTEM, WHICH IF FINE, BUT WHEN I GO TO THE INTERNET TO SEE IF I CAN JUST DO AWAY WITH THIS SYSTEM, THE FEEDBACK THAT I'VE FIND OUT WAS VERY UPSETTING, EVERYTHING ON DASH DOESN'T WORK, CAN'T GET INTO THE CAR, CARS DON'T START. THAT'S FINE BUT WHEN I TOOK THE CAR TO GET FIX THE SERVICE MANAGER AND WORKER TELL ME ANYTHING CAN HAPPEN WHEN THIS SYSTEM GOES DOWN. WHAT HAPPENS IF I'M DRIVING THE CAR AT HIGHWAY SPEEDS AND IT JUST STOP RUNNING, I HAVE NO BREAKS OR STEERING. IT'S CAUSES AN ACCIDENT.TO ME THIS IS A VERY SAFETY ISSUE. AND NOW THE PASSENGER SIDE BLIND SIDE IS BLINKING NOW, IT STOP BLINKING AND WORKING FINE FOR AWHILE AND THAN JUST QUITE WORKING.

I HAVE REPLACED MY HUB BEARINGS ON MY BOTH FRONT TIRES TWICE . I CONTINUE TO GET A GRINDING NOISE AND JERKING WHILE I'M TRYING TO ACCELERATE. WHILE REVERSING, TURNING LEFT OR RIGHT THIS HAPPENS. ALSO DOESN'T MATTER THE SPEED. THIS IS VERY DANGEROUS AS IT ALMOST CAUSED ME TO GET INTO SEVERAL ACCIDENTS. I PUT MY MONEY AND TRUST INTO CHEVY. THIS SHOULD BE ABSOLUTELY BE A RECALL.

THE POWER STEERING ON MY VEHICLE WENT OUT WHILE DRIVING ON THE EPXRESSWAY WITH NO ADVANCE WARNING. I RECEIVED AN ALERT ON MY DASH TO SERVICE POWER STERRING AND THAT WAS ALL. PER THE DEALERSHIP THIS WAS CAUSED BY A CATASTROPHIC INTERNAL FAILURE OF THE STEERING SYSTEM WHEN A GEAR BECAME BOUND UP BY A BROKEN SUSPENSION LINE AND COULD HAVE CAUSED A SERIOUS ACCIDENT

WHEN THE CAR IS TURNED ON AND NOT IN MOTION THE DASH DISPLAYS A SERVICE SIDE DETECTION SYSTEM MESSAGE AND THE BLIND SPOT DETECTORS IN THE SIDE MIRRORS DO NOT LIGHT UP LIKE THEY SHOULD WHEN THE CAR IS FIRST STARTED. WHEN DRIVING, AT ANY SPEED AND ON ANY ROADS OR HIGHWAY, THE BLIND SPOT DETECTORS DO NOT LIGHT. WHEN ASSESSED BY A CHEVY MECHANIC THE SIDE DETECTION SENSORS WERE SWOLLEN AND . CORRODED. THIS SENSOR IS IN AN AREA WHERE IT IS UNPROTECTED FROM THE SNOW AND SALT. IT WILL COST ALMOST $2,000 TO REPLACE TWO SENSORS. IF NOT REPLACED I'M AFRAID THAT MY VEHICLES WILL START CATCHING FIRE OR HAVING OTHER ELECTRICAL PROBLEMS LIKE OTHER 2015 IMPALA OWNERS HAD HAPPEN TO THEM IN THE PAST DUE TO THESE CORRODED SENSORS.

WHEN TURNING THE STEERING WHEEL ALL THE WAY TO THE LEFT AND ACCELERATING THE ABS ACTIVATES AND THE ABS LIGHT MOMENTARILY COMES ON. I JACKED UP THE FRONT OF THE CAR TO INVESTIGATE AND FOUND THAT I COULD CREATE THE ERROR BY JIGGLING THE WIRE TO THE ABS SENDING UNIT. GOOGLE THE ERROR AND NOTICE DOZENS OF OTHERS WITH THE SAME ISSUE.

BRAKE LIGHTS GASKETS ARE FAULTY FROM THE FACTORY AND ALLOW WATER TO FILL THE TRUNK WHEN IT RAINS. WHICH LEADS TO MOLD AND MILDEW SMELL THROUGHOUT THE VEHICLE. GM HAS PRODUCED A GASKET THAT IS "THICKER" AND CORRECTS THE PROBLEM BUT REFUSE TO ISSUE A RECALL AND DEALER SAYS ITS NOT COVERED BY WARRANTY. I'VE SPENT HUNDREDS AT DEALERSHIPS TRYING TO FIND FIND CAUSE OF THE WATER.

CRUSE CONTROL DEACTIVATES AND WON'T REACTIVATE WHILE CRUISING AT HIGHWAY SPEEDS. SEEMS TO WORK AGAIN AFTER SHUTTING OFF AND RESTARTING. THIS HAS HAPPENED SEVERAL TIMES. LAST TIME IT HAPPENED THE ENGINE ALSO DIED. COASTED TO THE SIDE OF ROAD, WAITED A MINUTE AND CAR RESTARTED AND SEEMED FINE, BUT HAPPENED A SECOND TIME A FEW MINUTES LATER. I WAS ON A STATE HIGHWAY WITH LIGHT TRAFFIC SO WAS IN NO IMMEDIATE DANGER, BUT WOULD HATE FOR THIS TO HAPPEN ON A BUSY SIX LANE INTERSTATE. NO DIAGNOSTIC CODES WERE SET BY THE COMPUTER SYSTEM.

ELECTRICAL MODULE (SIDE DETECTION) HAS FAILED TWICE. HAVE TO DRIVE TO GET REPAIR WITH NO GAUGES, SIGNALS, OR HEAT. THIS COULD EASILY BE A SAFETY ISSUE. THE CAR WAS PARKED, UPON STARTING, GOT SEVERAL ERROR MESSAGES INCLUDING SIDE DETECTION ISSUE, AIR BAG FAILURE, TIRE INFLATION FAILURE. NO SPEEDOMETER, TACHOMETER, HEAT - BUT THE STEERING WHEEL AND SEAT ELECTRICAL HEAT STILL WORK!

THE POWER STEERING CONTINUES TO GO OUT WHILE DRIVING. IT WILL BE DRIVING FINE AND THEN ALL OF A SUDDEN YOU HAVE NO CONTROL OVER THE VEHICLE. THIS IS A MAJOR SAFETY CONCERN. YESTERDAY IT HAPPENED WHILE I WAS DRIVING. I CAME TO A STOP TURNED THE CAR OFF AND BACK ON AND IT STILL WASN'T WORKING. I HAD TO GO BACK HOME AND FIND A DIFFERENT WAY TO WORK. IT HAS HAPPENED SO MANY TIMES I CAN NOT SOLELY RELY ON THAT CAR. THERE NEEDS TO BE A RECALL AND A FIX OF THIS PROBLEM.

THE SIDE DETECTION MODULES IN MY 2015 IMPALA HAVE GONE BAD FOR THE SECOND TIME IN LESS THAN 2 YEARS. THEY WERE REPLACED IN FEBRUARY OF 2019. THIS WAS MOSTLY COVERED THROUGH A SPECIAL "RECALL" TO REPAIR AND PREVENT A REOCCURRENCE OF THE FAILURE. NOW, IN DECEMBER ON 2020, I AM EXPERIENCING THE EXACT SAME CONDITION. THEY DID NOT REPAIR THE MODULES TO PREVENT THE SAME CONDITION FROM ARISING AGAIN. THEY GET WET BECAUSE OF A BAD DESIGN AND FAULT OUT, LEADING TO CAR SHUTTING DOWN OR EVEN FIRE FROM HARNESS TO MODULES CONNECTION. GENERAL MOTORS AND/OR THE DEALERSHIP (SUBURBAN CADILLAC, NOW SHAHEEN CADILLAC OF LANSING MI) SIMPLY REPLACED DISFUNCTIONAL PARTS WITH THE EXACT SAME DISFUNCTIONAL PARTS. A CONSUMER SHOULD NOT BE REQUIRED TO CONTINUOUSLY REPAY FOR A POSSIBLY DANGEROUS MALFUNCTION THAT THE COMPANY IS QUITE AWARE OF. I TRULY HOPE THAT THEY ARE NOT ALLOWED TO CONTINUE THIS IN THE FUTURE. THE REFUSAL TO ACCEPT FINANCIAL RESPONSIBILITY FOR REPAIRS DUE TO NEGLIGENT DESIGN AND INADEQUATE FIXES IS EVEN MORE ENRAGING.
