2008 Chevrolet Suburban Electrical System Problems

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.

DASH HAS CRACKED BY AIRBAG. ENGINE JUST STOPS WHILE DRIVING AND COMES RIGHT BACK ON AFTER VEHICLE IS TURNED OFF WON'T START NEEDS TO SIT AWHILE THEN IT STARTS AND RADIO N TEMP PANEL GOES TO DEFAULT.

REAR RADIO/CONTROL SYSTEM STARTED TO SMOKE WHILE STOPPED AT AN INTERSECTION ABOUT A MONTH AGO. WE HAVE NOT TRIED THE RADIO, BUT THE HEATED SEATS STILL WORK. WE ARE UNSURE IF WE SHOULD GO OUT OF TOWN WITH IT AND HAVE NOT HAD IT INSPECTED.

REAR RADIO/CONTROL SYSTEM STARTED TO SMOKE WHILE STOPPED AT AN INTERSECTION IN OCTOBER 2018. WE HAVE NOT TRIED THE RADIO, BUT THE HEATED SEAT DOESN'T WORK. WE ARE UNSURE IF WE SHOULD GO OUT OF TOWN WITH IT AND HAVE NOT HAD IT INSPECTED.

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 1500. WHILE DRIVING APPROXIMATELY 60 MPH, ALL THE WARNING INDICATORS ILLUMINATED AND THE CHECK ENGINE LIGHT KEPT FLASHING. THE BRAKING ABILITY SEIZED. THE CONTACT HAD TO MANEUVER TO THE SIDE OF THE ROAD. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE POWER CONTROL MODULE SYSTEM MALFUNCTIONED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VIN WAS INVALID. THE APPROXIMATE FAILURE MILEAGE WAS 150,000.

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.

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

3 DOOR LOCK ACTUATORS FAILED. THIS INCLUDES THE DRIVER SIDE DOOR. ALL FAILED WITHIN 6 WEEKS.

WHEN I TRIED TO OPEN REAR DOOR, IT WOULD NOT OPEN, DUE TO DOOR LATCH ASSEMBLY GOING BAD. ONLY KNOWING THIS IS A PROBLEM AFTER DOING SOME RESEARCH. NOW I DO NOT HAVE THE PROBLEM WITH NOT BEING ABLE TO OPEN DOOR AT ALL, THE MANUAL SWITCH STILL WORKS, BUT I SYMPATHY FOR THEM THAT DON`T. I CAN JUST IMAGINE IF I HAD TO GET A CHILD OR A HANDICAPPED ADULT FROM THE BACK SEAT IN A HURRY AND THE DOOR WOULD NOT OPEN FOR ME TO DO SO. I HAVE READ ON SOME OTHER SITES THAT GM IS AWARE OF THE PROBLEM, AND KNOW THE PART IS DEFECTIVE. I HAVE ALSO RESEARCHED ENOUGH TO KNOW THERE IS A NEW PART NUMBER FOR THE OEM PART. SO IF THEY KNOW IT IS JUNK, MAKE IT RIGHT. A HUMANS LIFE OVER A HAND FULL OF MONEY. NOT TOUGH FOR SOMEONE WITH FEELINGS TO MAKE. I HOPE THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION FINDS A WAY TO MAKE THEM TO REPAIR,REPLACE, AND IF SOMEONE HAS PAID TO FIX THEIR PROBLEM, BEFORE IT WAS RECALLED, REIMBURSEMENT. *TR

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.

FAILURE OF POWER ASSISTED DOOR LOCKS. DOORS WILL NOT OPEN WITH POWER SWITCH. SOLENOID HAS BURNT OUT. GM HAS RECOGNIZED PROBLEM WITH FAULTY PARTS MANUFACTURED IN CHINA. REPLACED FIRST SOLENOID THAT WAS CLOSE TO BEING UNDER WARRANTY. THE THREE OTHER UNITS THAT HAVE NOW FAILED WILL COST $90.00 EACH TO REPLACE. THOUSANDS OF COMPLAINTS HAVE BEEN FILED WITH THE NTSB AND GM BUT THE REFUSE TO DO A MANUFACTURERS RECALL. *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

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

REAR HATCH FAILURE. ELECTRIC OPENING. OPENED 24 INCHES AND THEN CLOSED UNDER MOTOR POWER. CAUGHT DOG IN THE DOOR THOUGH NO SERIOUS HARM DONE. HOWEVER IT DID NOT REVERSE AS IT IS SUPPOSED TO DO WHEN IT COMES DOWN ON AN OBJECT LIKE A CHILD OR DOG. DEALER REPLACED STRUTS WHICH SEEMS TO HAVE FIXED THE PROBLEM. THIS IS A SERIOUS FLAW. IT WAS JUST LUCKY IT ONLY CAUGHT THE DOG'S TAIL. IF IT HAD CAUGHT HER HEAD, SHE WOULD BE DEAD. *JS

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

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

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

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

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
