2015 Chevrolet Suburban Driver assistance Problems

The transmission was acting weird and felt like it was revving up and down while going 20-30 mph. After turning into my neighborhood there was a loud clunck like some dropped off the truck and it completely fell out of gear and just rolled to a stop. Shifted it into park, turned the truck off and back on and put it back in drive it went into gear and allowed me to drive to my house but still acted like it was about to drop out of gear completely again. My neighbor has a 2015 Silverado and 2017 Tahoe and both transmissions did the same thing and had to be replaced, all between 100-125k miles. The blind side system constantly goes off when there’s no threat

First, Side Detection System warning light would come on, then all dashboard gauges would fail and go to position as if the car war turned off, doors and windows would not unlock or open, series of warning messages would pop up as if all systems were malfunctioning. Car would still drive but if you turn the engine off all electrical systems would stay on for a extended period of time. Vehicle would not start, even with a jump start. After sitting for 12 hours, would start again and repeat shutdown after running for about 3-5 minutes.

It started with a glitch with the radio/navigation system flashing back and forth and not working. The cooling fan on the vehicle would run for about 10 minutes. The blind spot warning would blink on and off and there was no one else on the road. Then two days later the check engine light came on for about 5 days. Then three days later there was a loss of battery power and the indication light came on stating the car was in battery save mode. Then two days later the power steering system was lost on the highway and all the warning lights on the dash were flashing. The car stalled and refused to start. The tow truck driver tried to jump the vehicle with a battery pack that would jump a diesel and he only got enough power to put the car in neutral.

I purchased my vehicle after the recall 19V-645 regarding the brake pump was issued. My vehicle was a part of that safety recall, and the module was reprogrammed in September 2019 (N192268490-01). The pump has not been previously replaced according to service records. I purchased my vehicle from a dealership in April 2021. I recently (late 2023) started having issues with my brakes, having increased brake pedal effort, a hard brake pedal, and increased stopping distance. I have had the brake assist alert come on several times. The issue happens more frequently at lower speeds. My park assist alert also comes on regularly when applying the brakes. I have taken my vehicle to GM several times regarding the park assist issues, but they have only cleared the computer codes and cannot figure out why they keep coming back, as there is no detectable issues with the system. I have also brought my vehicle in due to the adaptive cruise control, as it has also caused issues while using it. It will often apply brakes if it detects a vehicle in another lane while driving, causing the vehicle to “slam” on the brakes going at high rates of speed (I.e. driving on the interstate at 80 mph) and has nearly caused accidents, as the vehicle becomes hard to control, and the risk of following vehicles not having the reaction time to avoid a rear-end collision is increased. My particular vehicle does not have an option to switch between regular cruise control, and adaptive cruise control. After talking with GM, they informed me the only way to “fix” the issue is to completely replace the module with an updated module that allows the option to turn off the adaptive cruise control, which is quite costly to the consumer. My vehicle is currently at a GM service department, and has been diagnosed that the brake pump has failed, and needs replaced. They are claiming that it is not covered under the recall. It is not covered under GM’s extended warranty due to mileage restrictions.

The vehicle will display “Service Trailer Braking System,” as well as “Service Front Camera,” “Service Driver Assist System.” These messages along with audible alerts will sound while driving. At random intervals, the forward collision system will also activate with no objects in sight. This causes the driver to become distracted or react quickly in unnecessary manner. This can increase risk of collision when the driver becomes distracted. The vehicle has been taken to Chevrolet multiple times and we have been told a faulty wiring harness is the cause. We own two of these vehicles, same make, model and year. This has happened in both vehicles.

WHEN TRAVELING AT SLOW SPEEDS, I.E., PARKING LOT OR RESTAURANT DRIVE-THRU LINE, AND MAKING SHARP TURNS, CAR STABILITRAK WARNING WILL FLASH THEN LOSS OF POWER STEERING AND COMPLETE LOSS OF POWER WILL RESULT. ADDITIONALLY, THE MEDIA ELECTRONICS WILL SHUT OFF AND RESTART PERIODICALLY. THIS DOESN'T NECESSARILY HAPPEN AT THE SAME TIME, ALTHOUGH, THIS NEVER HAPPENS WHEN I AM NOT HAVING PROBLEMS WITH THE STABILITRAK SYSTEM. (SEE PREVIOUS COMPLAINT: 11122704) TOOK CAR FOR SERVICE AT CAPITOL CHEVY ON 8/30/19. THEY SAID NO CODES WERE INDICATED, HOWEVER, THROTTLE BODY WAS DIRTY AND COULD HAVE AN EFFECT ON MY ISSUE. THROTTLE BODY WAS SERVICED/CLEANED. ON SEPT. 2, 2019 I HAD ISSUE WITH MEDIA SYSTEM AND STABILITRAK. WHILE TRAVELING SOUTHBOUND ON I-85, CRUISE CONTROL SET APPROX. 75 MPH, I BRAKED TO DISENGAGE CRUISE SPEED WHEN MEDIA SYSTEM RESET. I PULLED INTO MY DRIVEWAY APPROX. 20 MINUTES LATER AND WHILE TRAVELING AT SLOW SPEED AND TURNING IN MY DRIVEWAY, THE STABILITRAK WARNING CAME ON RESULTING IN LOSS OF POWER STEERING. I WAS NEARLY AT A STOP WHEN IT HAPPENED. SOMETIMES WHEN THE CAR LOSES POWER IN THESE SITUATIONS IT WILL HAVE TO BE JUMPED OFF TO RESTART. WHICH HAPPENED PRIOR TO BEING SERVICED ON 8/28/19.

VEHICLE LOSES BRAKING CAPABILITY AT LOW SPEEDS, SOMETIMES VOLTAGE ISSUES CAUSE STABILITY CONTROL ERROR, AND EVEN COMPLETE LOSS OF ENGINE POWER AND VEHICLE CONTROL (ENGINE SHUTOFF). THIS HAS BEEN RECURRING APPROXIMATELY ONCE PER DAY FOR TWO WEEKS, GENERALLY AT VERY LOW SPEEDS AND TURNING INTO A PARKING SPOT. TYPICALLY, ABS ENGAGE AND POWER BRAKE ASSIST IS LOST, WHICH REQUIRES MORE MORE EFFORT TO STOP THE VEHICLE. CAN ALSO HAPPEN IN REVERSE.

1) INTERMITTENTLY WHEN TURNING VEHICLE AT SLOW SPEEDS, THERE IS SUDDEN LOSS OF STEERING AND ELECTRIC POWER STEERING VIOLENTLY BOUNCING THE WHEEL BACK TO NEUTRAL POSITION WHEN ATTEMPTING TO STEER LEFT OR RIGHT. THERE IS ALSO SUDDEN LOSS OF ELECTRICITY, ENGINE TURNS OFF, REQUIRING TO SHIFT TO PARK AND RESTART ENGINE. THIS ISSUE USUALLY OCCURS AFTER RAIN OR AFTER CAR WASH (WATER ENTERING SHARK FIN ANTENNA) 2) INTERMITTENT COMPLETE POWER LOSS THROUGHOUT THE VEHICLE (OCCURS ESPECIALLY AFTER RAIN - WHEN SHARK FIN ANTENNA GETS FILLED WITH WATER) AND FEELS LIKE BATTERY IS SUDDENLY COMPLETELY DEAD. SOMETIMES IT CAN NOT BE JUMP STARTED IMMEDIATELY, AND AFTER MORE THAN AN HOUR, IT MAY BE JUMP STARTED. 3) WATER LEAKING INTO THE FRONT LEFT CORNER OF ROOF (DRIVER SIDE) AFTER RAIN - AGAIN DUE TO SHARK FIN ANTERNNA LEAK. THERE ARE MANY OWNERS OF CHEVY SUBURBAN/TAHOE, SILVERADO, GM TRUCK REPORTING EXACTLY SAME PROBLEMS ALL OVER INTERNET AND ON YOUTUBE. THIS PROBLEM STILL EXISTS AFTER THE RECENT 09/07/2018 RECALL 18V586000 FIX. THIS RECALL DID NOT HELP SOLVE THIS PROBLEM. IN MANY YOUTUBE VIDEOS PEOPLE REPORT HAVING FIXED THIS ISSUE BY REPLACING BATTERY POSITIVE AND GROUND CABLES, AS WELL AS BY REMOVING THE SOUND DAMPENING MATERIAL TRAPPED UNDER G218 GROUND ON THE DRIVER SIDE OF DASH (PEOPLE HAVE MENTIONED ABOUT INCREASED RESISTANCE ACROSS G218 GROUND).

THE 2015 CHEVROLET SUBURBAN THAT I DRIVE POWER GOES OUT WHEN I AM TURNING INTO A PARKING SPACE, MAKING A SHARP TURN, AND TRY TO COME TO A QUICK STOP. THIS HAPPENS EVERY TIME I AM DRIVING. IT ALSO DELAYS TO TURN OFF WHEN I AM PARKED. IT SOUNDS LIKE IT'S TRYING TO CRANK UP ON A LOW GAS LEVEL. SOMETIMES WHEN I AM AT A LIGHT AND TRY TO PRESS ON THE GAS, IT STALLS LIKE IT'S TRYING TO GET GAS.

AIR CONDITIONER WENT OUT UNEXPECTEDLY THIS WEEK. FRONT SEAT USB CHARGING PORTS WENT OUT AS WELL. A FEW DAYS LATER I ATTEMPTED TO STOP THE CAR BY BREAKING BUT THE BRAKES WOULD NOT ENGAGE. THE PEDAL FELT VERY HARD AS IF PRESSURE WAS ACTING AGAINST THE CARS ABILITY TO BRAKE AND STOP. I HAD TO PUSH DOWN WITH ALL MY FORCE TO KEEP THE CAR FROM CRASHING INTO ANOTHER CAR ON 1-95 IN FLORIDA. THIS OCCURRED ON NOVEMBER 21ST. I WAS ABLE TO MANAGE TO GET THE CAR BACK HOME AFTER TRAVELING FOR THE HOLIDAY BUT THE BRAKE FAILURE OCCURRED A DOZEN MORE TIMES ON BOTH THE INTERSTATE, SURFACE ROADS AND PARKING LOTS BY THE TIME WE GOT THE CAR HOME. THE BRAKE ASSIST NOTIFICATION ALSO SHOWED UP ON THE DISPLAY PANEL. MY FAMILY COULD HAVE BEEN SERIOUSLY INJURED OR KILLED! THIS CAR IS ONLY 3 YEARS OLD AND IS NOT DRIVEN THAT FREQUENTLY. NO REASON I SHOULD BE HAVING THESE ISSUES. DEALER THINKS IT IS THE VACUUM PUMP. HAVING DIAGNOSED.

THE NEXT DAY, 9/15/18, VEHICLE EXPERIENCED SAME PROBLEMS THAT WERE HAPPENING PRIOR TO BEING SERVICED. SPECIFICALLY, ON SATURDAY(9/15) AT APPROX. 4:30 P.M. CST, WHILE MAKING A ROLLING RIGHT HAND TURN ON GREEN THE VEHICLE LOST POWER STEERING AND LOST ALL POWER. NO ONE WAS DIRECTLY BEHIND ME AS I STOPPED IN THE MIDDLE OF THE CITY STREET. I PUT ON THE FLASHERS AND, AFTER UNSUCCESSFULLY TRYING TO RESTART THE VEHICLE IN NEUTRAL, WAS ABLE TO RESTART THE CAR WHILE IN PARK. I NOTICED THE BATTERY VOLTAGE METER WAS LOWER THAN NORMAL FOR THE REMAINDER OF MY TRIP, HOWEVER, IT HAD RETURNED TO NORMAL THE NEXT MORNING. THIS HAS BEEN AN ONGOING PROBLEM WHICH STARTED ON AUG. 9, 2018. FIRST TRIP TO THE CHEVY DEALERSHIP RESULTED IN REPLACING THE F-MODULE. PROBLEMS PERSISTED AND THE NEXT RECOMMENDATION WAS TO REPLACE THE NEGATIVE BATTERY CABLE, WHICH WAS DONE ON 9/10/18. NOW, AFTER SERVICING DUE TO RECALL, I CONTINUE TO HAVE THE SAME PROBLEM.
