2008 CHEVROLET SUBURBAN Electrical System Problems

I have a 2008 Suburban. Beginning in August, there was an accident on the highway and traffic was backed up. I was idling, waiting for the traffic to move, like every other car on the hightway and the suburban just shut off and said "Stablitrak off." It happened numerous times after this, just when idling. I took to the dealership I bought it at. They charged a ton to fix something but it didn't' take care of the problem. It's gotten so much worse. I took back a few months ago and they fixed it again, but didn't charge us this time. Now it's so much worse. Anytime I'm iding, just picking my daughter up at school or just stopped at a red light, a warning comes across, "service stabilitrak" or "stablitrak off." and the car immediately shuts off. It usually restarts in 5 minutes or so and I can usually make it to my destination as long as I don't idle again. Monday I was picking up my daughter and it stalled in the parking lot at her high school with tons of cars behind me- I waited, restarted it as I have done in the past. But then, going down this steep high school hill, the car shut off, lost steering and brakes wouldn't even work. I had teen drivers ahead of me that I nearly crashed into, teens in my car. This is not ok. We took it back to the dealership and now they say it's an electrical problem. I've read a ton online forums that this is something that happens with a lot of other people. I'm afraid to drive my car. I'm also not sure what to get fixed because these other people have spent tons of money, just like me with no results.

DRIVING WHEN YOU REACH ABOUT 30-35 MPH ALL THE LOCKS START CYCLING UP AND DOWN, ALL THE GAUGES GO HAYWIRE, THERE IS A THROTTLE IN THE ENGINE. WHEN YOU TURN IT OFF SOMETIMES IT STARTS BACK UP AND RUNS FINE AND SOMETIMES IT WON'T DO ANYTHING LIKE THE BATTERY IS DEAD AND THEN A FEW MINUTES LATER IT COMES BACK ON AND STARTS BACK UP. THE LAST INCIDENT WAS 01/09/20 BUT THIS STARTED IN 12/2019. THE VEHICLE HAS A BRAND NEW ENGINE WHICH ONLY HAS ABOUT 1,000 MILES ON IT. ALSO THERE IS A CRACK IN THE DASH AT THE CORNER OF THE PASSENGER SIDE AIR BAG.

IN 2008 IT WAS HARD FINDING A SUBURBAN AS A LOT OF DEALERSHIPS CLOSED ALREADY. SO I FOUND A DEALERSHIP IN GLENDALE CALIFORNIA. IT WAS FAR FROM WHERE I LIVED. WHEN I WAS OPENING THE SUNROOF IT STARTED GOING BACK AND FORTH. I COULDN'T BELIEVE IT. II HAD A LONG TRIP HOME AND I WAS HOPING THAT IT WOULD JUST RESOLVE ITSELF BUT IT NEVER DID. I HAVE TOLD CHEVROLET MANY TIMES ABOUT THIS PROBLEM AND YOU WILL FIND MY RECORDS OF HOW MANY TIMES I HAD CALLED THEM TO RESOLVE MY PROBLEM BUT THEY NEVER EVER DID A THING ABOUT IT AND IT IS STILL HAPPENING TO THIS DAY. ALSO I HAD JUST NOTICED A FEW SHORT MONTHS AGO THAT I HAVE FINE LITTLE HAIR CRACKS SHOWING UP ALL OVER MY SUBURBAN. ON THE HOOD AND ON BOTH SIDES OF THE CAR. I WENT TO MARTIN CADILLAC IN WEST LOS ANGELES THAT SERVICES CHEVROLET SUBURBANS AND THEY HAD TOLD ME YOUR CAR WAS PROBABLY REPAINTED UN-BENOIST TO ME. I HAVE HAD OTHER CARS BEFORE THIS ONE THAT I HAVE NOW AND I HAVE NEVER EVER HAD THE FINE LINES OF THE PAINT CRACKING ALL OVER MY CAR AND I CONTACTED CHEVROLET ON THIS AS WELL AND THEY SAID THEY COULD NOT DO ANYTHING FOR ME. I HAVE SEEN PAINT FADING AWAY ON CARS BUT NOT CRACKING AS MY SUBURBAN HAS ALL OVER THE CAR. IN THIS DAY AND AGE, WITH ALL THE SOPHISTICATED TECHNOLOGY AND THE WAY THINGS ARE DONE SO MUCH BETTER NOW THAN EVER BEFORE ON SOMETHINGS BUT NOT EVERYTHING AS I CAN SEE IT ON MY SUBURBAN. I CONTACTED CHEY ON THIS AS WELL AND THEY REFUSE TO GIVE ME ANY HELP ON THIS. I ALSO HAD A PROBLEM WITH MY BRAKES WHEN I GOT THE SUBURBAN. AS I CAME DOWN A STEEP HILL THE BRAKES STARTED TO CAUSE THE WHOLE CAR TO WOBBLE. I KNEW IT WAS THE BRAKES. I TOOK MY FOOT OFF THE BRAKE FOR A MOMENT THE WOBBLING STOPPED THIS WAS WHEN I HAD MY CAR FOR A FEW SHORT MONTHS. MARTIN CADILLAC'S SERVICE MANAGER SAID THE PAINT CRACKING SHOULD NOT HAPPENING MAYBE GLENDALE CALIFORNIA REPAINTED THE CAR. CHEVROLET HAS REFUSED ALL 3 CLAIMS.

TL* THE CONTACT OWNS A 2008 CHEVROLET SUBURBAN. WHILE DRIVING APPROXIMATELY 65 MPH, THE VEHICLE LOST POWER AND STALLED WITHOUT WARNING. THE VEHICLE WAS TOWED TO THE DEALER. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE AND VIN WERE UNKNOWN.

TL* THE CONTACT OWNS A 2008 CHEVROLET SUBURBAN. WHILE THE VEHICLE WAS IN PARK OR DRIVE, ALL FOUR DOORS FAILED TO UNLOCK AND THE KEY FOB FAILED TO UNLOCK THE DOOR. IN ADDITION, WHILE DRIVING 50 MPH, THE CHECK ENGINE, STABILITY TRACK DISENGAGE, AND TRACTION CONTROL LIGHTS ILLUMINATED. THE VEHICLE DECELERATED. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE OIL SPILLED AND CAUSED THE SPARK PLUGS TO FAIL. THE SPARK PLUGS WERE REPLACED NUMEROUS TIMES. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 70,000.

MY 2008 CHEVY SUBURBAN WITH 94,000 MILES STALLED WHILE IN TRAFFIC TRAVELING AT ABOUT 20 MPH WITHOUT WARNING. I LUCKILY WAS ABLE TO COAST IT TO THE SIDE OF THE ROAD AND AFTER LETTING IT SIT FOR A SHORT TIME IT DID RESTART AGAIN BUT ONLY TO STALL AGAIN AFTER THE CAR RAN FOR ANOTHER 5 MINUTES AGAIN TRAVELING AT ABOUT 20 MPH. I HAD IT TOWED TO MY DEALERSHIP AND HAVE BEEN TOLD THAT MY CRANKSHAFT POSITION SENSOR HAS FAILED. WHILE MY VIN AND YEAR IS NOT COVERED, THERE IS AN ACTIVE RECALL ON THIS CONDITION (GM RECALL NO. 06083.). THIS IS A VERY DANGEROUS ISSUE TO HAVE ESPECIALLY WHEN TRAVELING WITH SMALL CHILDREN IN THE CAR. THE RECALL SHOULD BE EXTENDED TO OTHER YEARS WHO EXPERIENCE THIS ISSUE FOR THE SAFETY OF FAMILIES. *TR

2008 CHEVROLET SUBURBAN. CONSUMER WRITES IN REGARDS TO THE DISAPPOINTMENT IN THE MANUFACTURER DUE TO NUMEROUS VEHICLE REPAIRS. *SMD THE CONSUMER STATED THE VEHICLE WOULD RUN ROUGH, THE CHECK ENGINE LIGHT ILLUMINATED, THE SERVICE STABILITRAK AND TRACTION CONTROL LIGHTS ILLUMINATED WHEN SOME OF THE CYLINDERS SHUT DOWN, THE LIFTERS WERE NOT PROPERLY LUBRICATED, CAUSING THEM TO FAIL. THE ENGINE CONSUMED LARGE AMOUNTS OF OIL. THERE WERE NOISES COMING FROM THE OIL PAN AND TRANSMISSION AREA, 3 OF THE 4 DOOR LOCKS ACTUATORS WERE REPLACED, THE REAR LIFTGATE BROKE FOR THE 4TH TIME, THE RIGHT RETRACTABLE MIRROR WAS INOPERABLE, THE CRUISE CONTROL WORKED ABOUT 505 OF THE TIME, WHICH WAS PROBABLY TIED THE THROTTLE POSITIONING SENSOR GOING BAD AS WELL. ALSO, THE VEHICLE HAD SIGNIFICANT ELECTRICAL PROBLEM, WHERE CERTAIN LIGHTS WOULD ILLUMINATE ON THE DASHBOARD, THERE WAS AN AUDIBLE CLICKING NOISE, THAT SOUNDED LIKE A RELAY FIRING VERY QUICKLY. *JB

ALL 4 AUTOMATIC DOOR LOCKING ACTUATORS DO NOT WORK. THE ACTUATORS DO NOT WORK WHEN THE LOCK/UNLOCK BUTTON IS PRESSED ON THE REMOTE. LOCKS DO NOT ACTUATE WHEN THE CAR IS PUT INTO PARK OR WHEN THE SPEED IS ATTAINED THAT IS SET IN THE SYSTEM SETTINGS. THE ONLY WAY TO LOCK/UNLOCK THE DOORS IS TO MANUALLY PUSH OR PULL THE DOOR LOCK. YOU CAN ALSO UNLOCK THE DRIVERS SIDE LOCK BY USING THE KEY. THIS IS UNSAFE. *TR

REAR HATCH DOOR ACTUATOR WENT OUT. THE DOOR IS IN THE LOCKED POSITION AND CANNOT BE OPENED WITH CONSOLE BUTTON, KEY FOB OR EXTERIOR HANDLE. THERE IS NO WAY TO OPEN THE REAR HATCH FROM THE INSIDE OF THE VEHICLE CREATING A SAFETY HAZARD FOR PASSENGERS RIDING IN THE 3RD SEAT. THE REAR HATCH IS NOT ACCESSIBLE FOR USE SINCE I IS IN A LOCKED POSITION AND CANNOT BE OPENED. I HAVE FILED A COMPLAINT WITH GM. THEIR CS REPRESENTATIVE CONTACTED ME TO LET ME KNOW THAT MY LOCAL DEALERSHIP CAN FIX THE PROBLEM AT MY EXPENSE. TENS OF THOUSANDS OF THESE COMPLAINTS HAVE BEEN FILED WITH GM OVER THE LAST 2 YRS. AND THERE HAS BEEN NO RECALL FOR THIS POTENTIALLY FATAL SAFETY HAZARD. *TR

I PURCHASED A 2008 SUBURBAN LTZ IN JULY 2011. SHORTLY AFTER WE PURCHASED THE VEHICLE 3 OF THE DOORS LOCKS HAVE STOPPED FUNCTIONING COMPLETELY, THE 4TH DOOR WORKS SPORADICALLY (DRIVER SIDE, PASSENGER). THE LOCKS DO NOT WORK AT ALL WITH THE KEYLESS ENTRY NOR THE MAIN LOCK BUTTON FROM THE DRIVER SIDE DOOR. I HAVE BEEN TOLD THAT IT IS A PROBLEM WITH THE LOCK ACTUATORS MALFUNCTIONING AND THAT IT IS ALSO A WELL KNOWN ISSUE FROM VARIOUS DEALERS AND PER MY RESEARCH ON THE INTERNET. IN ORDER TO UNLOCK THE DOORS, I MUST MANUALLY USE THE KEY TO UNLOCK THE DRIVER SIDE DOOR THEN UNLOCK ALL THE OTHER DOORS BY HAND ONE BY ONE. THEN WE MUST LOCK ALL DOORS MANUALLY AFTER ENTERING BECAUSE THE LOCKS ALSO DO NOT LOCK AUTOMATICALLY WHEN YOU TAKE THE CAR OUT OF THE PARK POSITION. ALTHOUGH THE POWER LOCKS ARE A LUXURY, THIS ALSO BECOMES A SAFETY ISSUE. A VEHICLE WITH AN ORIGINAL ASKING PRICE OF OVER $55,000 SHOULD NEVER HAVE THIS ISSUE AND I'M NOT SURE WHY CHEVROLET FAILS TO TAKE ACTION FOR A CLEAR SAFETY DANGER. AS A MOTHER OF 3 CHILDREN I FIND THIS TO BE A VERY SERIOUS SAFETY ISSUE. A CHILD COULD EASILY OPEN THE DOOR AND FALL OUT OF THE MOVING VEHICLE OR IF WE WERE INVOLVED IN A CAR ACCIDENT ANY ONE OF MY FAMILY MEMBERS (ADULT OR CHILD) COULD POTENTIALLY BE EJECTED FROM THE VEHICLE, CAUSING EITHER SERIOUS INJURY OR WORSE!! I REALIZE THE CHILD SAFETY LOCKS CAN BE ACTIVATED TO KEEP A CHILD FROM OPENING THE DOOR ACCIDENTALLY, BUT THAT WILL NOT PREVENT A CARJACKER OR ANYONE ELSE FOR THAT MATTER FROM JUMPING IN AND STEALING THE CAR OR KIDNAPPING A CHILD. IN MY OPINION, THEIR DEFINITELY NEEDS TO BE A RECALL ISSUED FOR THIS MAJOR LOCKING MALFUNCTION BASED ON MY EXPERIENCE AND HUNDREDS OF OTHERS I HAVE RESEARCHED. *TR

Mileage: 50,000

DRIVER SIDE REAR DOOR LOCK QUIT WORKING, SHORTLY AFTER THAT DRIVER DOOR QUIT LOCK QUIT WORKING, TOOK INTO DEALER FOR REPAIR, SAID IT WOULD BE ABOUT $1000 FOR 2 DOOR LOCK ACTUATOR REPLACEMENTS, A FEW MONTHS LATER THE PSGR REAR DOOR LOCK QUIT WORKING. *TR

DOOR LOCK ACTUATORS FAIL CAUSING DOORS TO REMAIN LOCKED AND INOPERABLE. SEVERAL ACCOUNTS ON THE INTERNET CLAIM MULTIPLE FAILURES AT THE SAME TIME AND OR REPLACED ACTUATORS FAILING A SECOND TIME. VEHICLE CAN NOT BE ENTERED OR EXITED EASILY IN AN EMERGENCY CAUSING A SAFETY ISSUE. *TR

Mileage: 60,000

DRIVER'S SIDE FRONT DOOR LOCK ACTUATOR QUIT WORKING COMPLETELY. THE PASSENGER SIDE FRONT DOOR LOCK ACTUATOR WORKS INTERMITTENTLY.

Mileage: 34,285

DRIVING THE CAR ON CITY STREET, LET OFF GAS TO SLOW DOWN, ENGINE SHUDDERS, THE INSTRUMENT CONSOLE FLASHES, INDICATES ENGINE POWER DECREASING, THE RADIO STOPS WORKING, THE VEHICLE LOSES POWER, THE STABILITRAC INDICATES IT NEEDS TO BE SERVICED, GIVES REAR CAMERA/TOWING WARNING, THE ENGINE DIES, BRAKES ARE LOST. IMMEDIATELY AFTER ENGINES DIES STARTER WILL NOT CRANK. THE CAR WILL START AGAIN AFTER SEVERAL MINUTES. CHECK ENGINE LIGHT IS ON. AFTER A DRIVE OF ABOUT 4 MILES PARKED CAR AND STARTED NEXT MORNING--CHECK ENGINE LIGHT IS OFF. ENGINE QUITTING AND NO BRAKES COULD BE DANGEROUS. INTERMITTENT PROBLEM. *TR

Mileage: 36,000

BATTERY GOES DEAD EVERY THIRD DAY THAT THE TRUCK IS NOT USED. BATTERY IS GOOD. *TR

Mileage: 76,000

AFTER DRIVING FOR APPROXIMATELY 3 HOURS THE PROBLEM BEGAN: THE DOOR LOCKS CYCLE REPEATEDLY, THE INSTRUMENT CONSOLE FLASHES, THE DRIVE POSITION FLASHES FROM PARK TO DRIVE REPEATEDLY, THE RADIO STOPS WORKING, THE VEHICLE SURGES, AND THE STABILITRAC SAYS IT NEEDS TO BE SERVICED. THIS IS THE SECOND REPORT WE HAVE FILED IN A MONTH. WE HAVE ALREADY TAKEN IT TO THE DEALERSHIP ONCE FOR THIS PROBLEM IN EARLY AUGUST WHEN IT WAS JUST THE RADIO MALFUNCTIONING. THEY SAID TO REPLACE THE RADIO. THIS IS A SAFETY ISSUE THAT HAS ALREADY BEEN IDENTIFIED BY NHTSA ITEM NUMBER 10036550 AND SERVICE BULLETIN NUMBER PIT-4730A. GM SAYS THAT BECAUSE OUR VEHICLE IS OUT OF FACTORY WARRANTY THAT THEY WILL NOT PAY TO HAVE IT REPAIRED. *TR

HAVE REPLACED AC BLOWER MOTOR, RESISTOR, AND DRIVER FRONT DOOR LOCK ACTUATOR. IT IS NOW THE DRIVER BACK DOOR LOCK NOT WORKING. ALSO, VEHICLE BEGAN RUNNING ROUGH; TOOK IT TO MECHANIC; SENT ME ON TO DEALER. HAD TO REPLACE ALL FUEL INJECTORS AND CAMSHAFT. *TR
