ELECTRICAL SYSTEM
While driving at highway speeds my vehicle lost steering the radio and the hvac turned off. I had abs and brake lights on the dash as well as a service stabilitrac message. The vehicle completely shutoff and I almost had an auto accident. I have not taken it anywhere as I’m to afraid to drive it for fear of having an accident.

When driving down the road, all gauges drop to 0, car continues to drive. When I pull over and try to turn the car off it turns everything off except the engine. I can’t put it into gear or restart the car. Battery has to be unplugged to get it to turn off. All lights will start flash across the dash. Service air bags, service trailer brake, service side detection, etc

ELECTRICAL SYSTEM:INSTRUMENT PANEL:SPEEDOMETER/ODOMETER
Odometer Fraud. The contact purchased a 2015 Chevrolet Suburban. The contact stated that while attempting to have the vehicle inspected, it was discovered that the catalytic converter was missing, the wires were cut, and a pipe was inserted to muffle the noise. The contact was told that the check engine warning light was turned off and the carbon monoxide was not being cleaned, and that fumes were entering the cabin of the vehicle. The contact also discovered that there was a mileage discrepancy on the vehicle. The vehicle was a dealer sale. At the time of purchase, the mileage was 131,000 and at the time of the inspection, it was discovered that the mileage was approximately 231,000.

ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM
While driving approximately 70 miles an hour and trying to switch lanes, we got a stabilitrack warning and the car shut off for a second and then came back on. the weather was nice and there was no snow or any other adverse conditions. This happened a couple more times on the ride and then when we tried to turn into a parking spot it shut off completely and we had to restart it. We turned stabilitrack off and the car was ok for a couple of short drives. Then driving late at late and we passed another car the same thing happened. Then when we tried to turn our brights on we got the same message. Then we got a brake assist message and then we got a collision alert. The headlights were flickering the rest of the drive and we couldnt use our brights. We had our 4 children in the car and it was shutting down at high speeds and very scary. I looked up our vin and it said that the recalls had been worked on but I dont remember this being done. This has never happended before this. our car would be available for inspection if needed.

ELECTRICAL SYSTEM
Vehicle lost power steering turning a tight left into a parking space at a low speed on 5/18/2024. A second later, the engine and all electrical in the vehicle went dead. The steering locked and nothing electrical in the vehicle was functional. Based on the online information and comments found, this is a significant problem with the 2015 Suburban. The GMC recall number is 14743. The recall was for replacement of the power steering assist motor kit. When I look up my vehicle on the recall listing there are no recalls for my vehicle. There is an obvious problem which is effecting these vehicles and dealers shouldn't question the safety implications of steering and engine failure while the vehicle is moving.
NHTSA complaint #11589637 — an unverified report by a vehicle owner.
ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM
The power steering locks up at random times while I am driving my vehicle. It seems to be temporary loss of power steering because it eventually starts working again. It feels almost impossible to turn the car when this happens. I searched online and found there had been a recall on the EPS (Electric Power Steering) for this exact issue. I called the local dealership, they told me after searching my vin that the recall had already taken place in 2019. The repair or recall that was done did not fix the problem.

ELECTRICAL SYSTEM
Vehicle loses power steering when turning at slow speeds which was part of a recall from 2018. Reflashing the module didn't fix the issue and has been doing it again for a year now except that now it occasionally loses power as well and has twice lost power while I was turning and oncoming traffic coming at me. GM is saying it is not the same issue as the prior recall, but I disagree and that the work done prior didn't fix the safety hazard. An 8 year old vehicle shouldn't be losing power while driving to where the battery cables have to all be replaced. That should have been the work GM did back when they first put out the recall for the loss of power steering.

ELECTRICAL SYSTEM
The Service Trailer Brake System keeps popping up. Keeps dinging off and on whether you push the dismiss button or not. When this is on I question if the electrical brakes will work when I tow our camper. It is very distracting while driving. Safety Concern for sure!
NHTSA complaint #11444084 — an unverified report by a vehicle owner.
ELECTRICAL SYSTEM
The system that is failing is on my Suburban is the Trailer Break System, yes it is available for inspection. The continuous alert is distracting to the point of the vehicle being un-drivable and without the trailer break system functioning properly it puts people in danger due to not being able to safely stop while towing. The dealership said they were unable to reproduce the code. The vehicle has not been inspected by anyone except the dealership. Yes, both a visual and audible alert pops up continuously with a loud “ding” and a “Service Trailer Break System” warning.

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.

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).
