2017 CHEVROLET SUBURBAN Electrical System Problems

While driving, the vehicle has repeatedly experienced sudden loss of power and electrical failures without warning. During these events, the dashboard flickers, warning messages appear, and the vehicle shuts off or goes into reduced power mode. When this occurs, steering becomes extremely difficult, braking becomes stiff, and the vehicle cannot accelerate. These incidents have happened multiple times in different driving situations, including: At stoplights While pulling into intersections Backing out of parking spaces Driving on public roads, including dark rural roads Driving with my three minor children in the vehicle On at least one occasion, the vehicle shut off while pulling onto a road with oncoming traffic, leaving us stopped in the roadway with no power and limited steering/braking. This created an immediate and serious risk of collision. The vehicle eventually restarted after several attempts. The problem has occurred repeatedly over many months. Multiple independent repair facilities have attempted to diagnose and repair the issue, but no definitive cause has been identified, and the failures continue. The vehicle has had numerous electrical, sensor, engine, and powertrain-related repairs, yet the loss-of-power events persist. Because the vehicle can suddenly shut down while in motion and compromise steering and braking, I believe this is a serious safety defect that could result in a crash, injury, or worse.

Sitting in my truck and everything just stopped working. Starter was still going even with the key out of the ignition and there was a burn smelling come from under the engine and the truck wouldn't Starter. Had to get it tow from my job. Till this day my truck is still down. Engine be replace and the dealership still don't know why it still wouldn't starter. Also before the electrical problem. Me and my family was come down the highway from a vacation and the engine when i lost acceleration to the engine. The speed limit was 65 I can only do 25 because the engine lost acceleration. I only had the truck for three months. People told me that there was recalls on engine problem with the Chevrolet suburban and Tahoe. I looked it up and it is for 2019 and up. So know i have to pay 3800 to replace everything. I cant afford to replace anything I cant afford I use vehicle. The dealership that I got the vehicle from is closed down because they was lemons to people know everyone is stuck with a vehicle that they still have to pay the bank. And can't drive there vehicle. It's not right they have recalls on vehicles that are 2019 and up. I'm just looking for help. Because to be honest me and my family wouldn't be here because of the engine and electrical problem. So can someone please look in to this from a sincere father, husband, grandfather. The dealership name is Stratum auto group. 2050 Burlington-mount holly

When turning the car left, the power to the engine dies. This also happens on many instances that the power has died to the engine mid drive on the road and hwy. Suddenly the forward collision note appears on the dash and other warnings appear after and then the power dies to the engine. Must stop and restart the engine for it to reset. Yes, it is available for inspection. While driving at high speeds the forward collision appears, and the car can suddenly die mid drive. Even at highway speeds. No, they claim that they cannot reproduce the issue. It has been taken to the dealer at least 5 times It appeared after seat heat function went out and was worked on

I purchased this car at CarZone in Riverside This April 2024. I drove home with my kids in the dark and people kept honking. The lights and turn signals did not work. I took the car back in. The back up camera was broken, the safety system is broken, brakes are bad, they put two bald and all four tires with gummy plugs after I brought it back a fourth time. The tires were not fixed. I found out driving on the highway with my daughter. My tires popped. I had to pay for all four to be replaced and the dealership will not take any of my calls. I then had a check oil light. I took the car in. Pep boys discovered they had replaced the oil hose with a different one. It backed up into the engine. I paid for an oil change and was told to keep an eye on it and contact the dealership. They would not respond. I went back to pep boys be my car was completely out of oil one week later and my headlights kept dying and the car wont accelerate. They did another diagnostic and contacted the dealership and warranty saying it needs a new engine entirely. They sent an adjuster who said nothing was wrong and closed it. I have had to take the car back since. The liftgate is zip tied to the tail pipe. I am terrified to drive this car, especially the head light and brakes. I bought new tires bc the dealership would not help even though I have all the text messages they sent about the issues. It no longer accelerates the way it should and I have to put three quarts of oil minimum per week to keep it running at all. I am out so much money that I do not have and I cant drive an unsafe car with my babies in it. Upon further investigation I have found this dealership has done this to many people. I just need help getting them to take this car back or pay to fix it and to make sure they are following safety laws. I feel responsible to report this because I know I wish someone else had and it would be absolutely devastating if someone got injured in a vehicle sold by them.

Despite replacing Throttle Body and Accelerator Pedal Position Sensor, I continue to have my Suburban go into Reduced Engine Power without much warning. It is very dangerous when you are driving on the freeway and your vehicle suddenly will not do over 35mph with the engine revving to 4000+ RPM. I've spent nearly $1000 at repair shops and have found that nothing they attempt will fix the problem. I cannot trust vehicle with my wife and kids riding any distance in it.

The electrical system has gone out completely comes back a few seconds later with different icons saying to roll driver side window down then up, or stabiltrax. It has also caused complete electrical failure being on a road while driving. This has also cause my wheel to jerk taking out the power steering and the engine has shut off completely to the point where I have to wait a few minutes to even turn it on. This has happened while reversing in to a parking spot and the whole car dies. It kills power so much that I have no hazard lights. When I’m able to get it to come Back on it’s like it reset its self. I have taken it to the shop and they have said the battery cables and the mega fuse above the battery. I know this is a known issue in other like vehicles.

Persistent SERVICE TRAILER BRAKE SYSTEM warning indicator. Warning constantly sounds. Vehicle cannot be driven safely due to the sound and vehicle is unable to tow. I have spent thousands of dollars to correct the issue (replaced transmission and other elements) at the recommendation of the dealership service department. Issue is still unresolved.

The entire electrical system shuts down including lights while driving down the road. No driving light or display at night for about 30 seconds then come back on. System also loses all displays on dash during the day as well.

While driving the cars loses all power and you can’t steer. It used to only happen when turn at a slow speed. And now when you’re driving it matter what speed it shuts off and you lose all power. Nothing comes up for service on diagnostic it is very dangerous I have a family have sex and no one can find out what’s wrong with it

VEHICLE DASH AND HEADLIGHTS TURN OFF WHILE DRIVING, ENGINE STALLS AND DIES, POWER STEERING BECOMES INOPERATIVE. TRANSMISSION POPS OUT OF GEAR AND FREEWHEELS. SERVICE STABILITRACK LIGHT. VERY DANGEROUS SITUATION FOR MY WIFE AND 5 KIDS WHEN THIS HAPPENS ON CURVY BACKROADS AT NIGHT LIKE JUST HAPPENED LAST NIGHT! THIS IS ALSO THE SAME PROBLEM AS OUR PREVIOUS CHEVY TAHOE SO WE KNEW THE PROBLEM WAS LIKELY RELATED TO POOR QUALITY BATTERY CABLES THAT ARE DEGRADING PREMATURELY. THIS SHOULD NOT BE HAPPENING ON A 3-4 YEAR OLD VEHICLE. AFTER SEARCHING A GM WEB FORUM AND FINDING OTHER PEOPLE COMPLAINING ABOUT THE SAME ISSUE, THERE WAS A REFERENCE TO GM TSB 18-NA-161 ON THIS EXACT ISSUE I AM ABSOLUTELY AMAZED THAT GM HAS NOT DONE A RECALL ON THIS YET, AS IT IS A MAJOR SAFETY FAILURE LIKELY TO CAUSE A CRASH AND POTENTIALLY A FATALITY. I CHECKED THE TIGHTNESS ON THE CONNECTIONS BY HAND, WHICH WERE BOTH VERY TIGHT, THEN I RESEATED AND TORQUED THE BATTERY TERMINAL CONNECTION. I MEASURED THE RESISTANCE ACROSS THE POWER JUMPER, LUG TO LUG. THIS IS GM PART NUMBER 84494554, AND I MEASURED 0.3 OHMS ACROSS THIS LITTLE SECTION OF WIRE AT MULTIPLE POINTS ON THE LUGS. TRIMMING BACK THE INSULATION AND CONTINUING THE MEASURE, THE HIGHEST RESISTANCE APPEARS TO BE COMING FROM THE WIRE TO THE LUG CONNECTION AT THE FUSE BUS, AND NOT THE CRIMP CONNECTION AT THE BATTERY TERMINAL, AND NOT THE BOLTED CONNECTION TO THE BUS. THERE WERE SOME STRANDS BROKEN AT THIS CONNECTION. I MADE AND ADDED A TEMPORARY JUMPER OF THE SAME WIRE GAGE, AND THE RESISTANCE ACROSS THE SAME MEASURED POINTS DROPPED TO 0.0 OHMS. ABSOLUTELY A MAJOR SAFETY ISSUE IF THE VEHICLE SUDDENLY DIES WITHOUT WARNING. I CAN SEE THIS SAME ISSUE HAPPENING ONCE, I FORGAVE GM ONCE YEARS AGO, BUT WITH THE SAME ISSUE HAPPENING TO TWO DIFFERENT VEHICLES 8 MODEL YEARS APART, THE SAFETY OF MY FAMILY IS TOO IMPORTANT TO BUY GM PRODUCT IN THE FUTURE.

WHEN I RE-STARTED THE VEHICLE THE STEREO MEMORY ERASED AND THE ROLL DOWN, THEN BACK UP DRIVER AND PASSENGER WINDOWS WARNING FLASHED AGAIN. THIS IS ALL UNSETTLING BECAUSE I FREQUENTLY DRIVE IN AREAS OF HEAVY TRAFFIC AND INTERSECTIONS THAT CAN BE TRICKY TO CROSS/TURN INTO THEREFOR REQUIRING MY VEHICLE TO RESPOND APPROPRIATELY AND NOT TURN OFF WHILE IN GEAR.

THIS VEHICLE KEEPS HAVING KEY FOB, ELECTRICAL ISSUES, TIRE SERVICE MAINTENANCE ISSUES, AND NOW ENGINE ISSUES RELATED TO THE KEY FOB. THE KEY FOB KEEPS SAYING IT IS NOT DETECTED. RECENTLY, WHILE DRIVING ON ROAD AT ABOUT 48 MPH, KEY FOB NOTIFICATION CAME ON DASHBOARD SAYING KEY FOB WAS NOT DETECTED, ENGINE SHUT OFF AND CAR HAD TO BE RESTARTED AGAIN USING FOB BOX INSIDE GLOVE COMPARTMENT, THIS WAS PARTICULARLY ALARMING. THE KEY FOB HAS HAD BATTERIES REPLACED AND THEY WORK BECAUSE THE CAR WILL REMOTE START AND HAVE TRIED BATTERIES IN OTHER ITEMS. THE FOB DOES NOT HOWEVER LET YOU UNLOCK THE CAR OR FINISH STARTING IT OUT OF THE REMOTE START ONCE YOU GET INTO THE CAR AND TRY TO START IT, THE CAR TELLS YOU IT CANNOT DETECT THE REMOTE. THE CAR HAS HAD NUMEROUS KEY FOB ISSUES AND HAS BEEN TAKEN INTO LOCAL CHEVROLET DEALER WHO CANNOT FIND ISSUE. THE CAR HAS ALSO HAD 142 HARD BRAKING EVENTS SINCE APRIL 2019 TO NOVEMBER 2019 ACCORDING TO ON STAR REPORTS. THE TIRE SERVICE MONITOR KEEPS FLASHING THAT THERE ARE ISSUES WITH TIRES. THE REAR WIPER WOULD NOT SHUT ITSELF OFF EVEN THOUGH BUTTON WAS IN OFF POSITION. ALL OF THESE ISSUES HAVE NOT BEEN ABLE TO BE REPAIRED AT THE CHEVY DEALER. THIS CAR IS GOING BACK IN FOR SERVICE 11/18/19 FOR THESE ISSUES AGAIN. NOT SURE WHAT THE OUTCOME WILL BE UNTIL AFTER THIS APPOINTMENT. MY GUESS IS THAT IT IS SOME KIND OF ELECTRONIC CIRCUITRY PROBLEM(S) BUT UNFORTUNATELY THE DEALER SAYS THEY CANNOT FIND ANY ISSUE(S) OR PROBLEM(S) UNTIL IT COMPLETELY SHUTS DOWN. THESE EVENTS ARE ONGOING AND HAVE BEEN OCCURRING INTERMITTENTLY SINCE NOVEMBER 2018. ALL I CAN PROVIDE IS PHOTOS OF THE DASHBOARD SHOWING WHAT IT RELATES TO ME UNFORTUNATELY I HAVE NO DOCUMENTATION OF ENGINE SHUTTING OFF ONLY A PHOTO OF WHAT DASHBOARD SHOWED WHEN IT HAPPENED.

WE WERE IN MOTION AND THE CAR SUDDENLY DIED COMPLETELY. WE WERE LATER TO LEARN THAT THE BODY CONTROL MODULE (BCM) HAD SHORTED OUT. WE LEASED THE CAR BRAND NEW AND HAD ONLY HAD IT FOR THREE MONTHS WHEN THIS OCCURRED. THANKFULLY WE WERE NOT IN A BUSY ROAD WHEN IT HAPPENED, OTHERWISE WE COULD HAVE BEEN KILLED. ON TOP OF THIS, THE CHEVROLET DEALERSHIP TO WHERE THE VEHICLE WAS TOWED TOLD US THAT IT WAS NOT COVERED UNDER WARRANTY AND REQUIRED US TO PAY TO REPLACE THE BCM (INITIALLY THEY QUOTED AROUND $700, BUT THEN AFTER WE COMPLAINED, THEY SAID THEY'LL "SPLIT IT WITH US" AND REDUCED IT TO AROUND $350).
