2001 CHEVROLET SUBURBAN Electrical System Problems

ON MARCH 16, 2017, I WAS TRAVELLING ON A MOUNTAIN HIGHWAY IN NORTHERN CALIFORNIA IN MY 2001 SUBURBAN WITH THE DRIVER'S SEAT HEATER ON. I WAS SITTING ON A THIN SEAT CUSHION. TWENTY MINUTES INTO THE 40 MINUTE TRIP, I TURNED MY SEAT HEATER OFF. TEN OR SO MINUTES LATER, I SMELLED A HORRIBLE RUBBER/PLASTIC BURNING SMELL. WHEN I REACHED MY DESTINATION, I LIFTED MY CUSHION AND SAW THAT THE SEAT HAD A BURNED HOLE THROUGH THE LEATHER AND INTO MY SEAT CUSHION. IT WAS WARM, BUT I DID NOT SEE A FLAME. WHEN I GOT HOME IN THE BAY AREA, I CONTACTED GM, AND THEY OPENED A CASE NUMBER AND TOLD ME TO TAKE MY VEHICLE TO A DEALER, AND THEY WOULD INVESTIGATE. I RECEIVED A CALL YESTERDAY FROM THE CUSTOMER SERVICE REP., AND SHE TOLD ME THAT THEY WOULD NOT BE COVERING THIS AS MY CAR WAS OUT...

TL* THE CONTACT OWNS A 2001 CHEVROLET SUBURBAN. THE CONTACT STATED THAT WHILE TRAVELING VARIOUS SPEEDS, THE VEHICLE STALLED. THE CONTACT ALSO MENTIONED THAT THE IGNITION WAS ABNORMALLY LOOSE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT CONTACTED ABOUT THE FAILURE. THE FAILURE MILEAGE WAS NOT AVAILABLE.

TL* THE CONTACT OWNS A 2001 CHEVROLET SUBURBAN. THE CONTACT STATED THAT THE VEHICLE FAILED TO START WITHOUT WARNING. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC, WHO DIAGNOSED THAT THE CAME SHAFT NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED BECAUSE THE REPLACEMENT PART WAS NOT READILY AVAILABLE. THE MANUFACTURER WAS MADE AWARE OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 124,000. UPDATED 04/15/14 MA

MY VEHICLE'S "SERVICE ENGINE SOON" LIGHT CONTINUES TO LIGHT UP EVEN AFTER HAVING THE CODE ERASED. MANY OTHER OWNERS OF CHEVROLET SUBURBANS HAVE THE SAME ISSUE. OBD CODE P0332 STATES THE KNOCK SENSOR HAS LOW VOLTAGE. THE PROBLEM MANY PEOPLE HAVE IS WHEN WATER OR MOISTURE GETS INTO THE ENGINE COMPARTMENT WATER BEGINS TO POOL OVER THE SENSOR AND SEEP INTO THE SENSORS. THE LACKING OF WATER SEAL IN THIS POOLING AREA DAMAGES THE SENSORS. THE VEHICLE THUS CANNOT PASS IT'S BI-YEARLY SMOG TEST AND ALSO CREATES A FALSE SENSE OF VEHICLE RELIABILITY. IF OTHER ISSUES COME UP OTHER THAN THE BAD SENSORS THE DRIVER WOULD NEVER KNOW. *TR

TL* THE CONTACT OWNS A 2001 CHEVROLET SUBURBAN. THE CONTACT STATED THAT WHILE DRIVING 55 MPH, THE LIGHTS ON THE INSTRUMENT PANEL STOPPED ILLUMINATING. THE VEHICLE WAS TAKEN TO THE DEALER.

THE FAILURE MILEAGE WAS 115,000 AND THE CURRENT MILEAGE WAS 145,000.

TL* THE CONTACT OWNS A 2001 CHEVROLET SUBURBAN.

THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 190,000.

FIRST INCIDENT: VEH. WOULD CRANK BUT NOT START. TURNED OUT TO BE FUEL DELIVERY FUSE. REPLACED, AND RAN FINE FOR SEVERAL WEEKS. SECOND INCIDENT: DRIVING AT APPROX. 55 MPH, VEHICLE LOST POWER, STARTED SPUTTERING AS IF OUT OF GAS ALTHOUGH IT WAS 1/4 FULL. UNABLE TO EXCEED 25 MPH DUE TO LITTLE/NO POWER. WAS TOWED TO AUTOPARTS STORE, CLEARED CODES, VEH RAN FINE FOR ABOUT 2 DAYS, THEN LOST POWER. TOWED HOME. LOOKED UP INFO ON INTERNET, FOUND RECALLS FOR FUEL PUMP. CALLED LOCAL CHEVY DEALERSHIP, INQUIRED ABOUT RECALL, WAS TOLD THAT RECALL WAS ONLY ON HALF-TON SUBURBANS AND SINCE MINE IS 3/4 TON, IT WAS NOT COVERED BY RECALL. I REPLACED FUEL MODULE MYSELF AND DISCOVERED THE COVERING OF THE WIRES INSIDE THE FUEL MODULE ASSEMBLY HAD MELTED, ALLOWING THE BARE WIRES TO RUB AGAINST EACH OTHER, SHORTING OUT THE FUEL DELIVERY SYSTEM (WHICH LIKELY CAUSED THE BLOWN FUSE...

WE NOTICED THAT THE DRIVER'S SIDE MIRROR OF MY WIFE'S 2001 TAHOE APPEARED TO HAVE A MELTED PLACE ON THE BOTTOM OF THE PLASTIC HOUSING. THERE WAS A GREEN/YELLOW CIRCLE IN THE CENTER OF THE MIRROR WHERE IT APPEARED TO HAVE GOTTEN TO HOT. I REMOVED THE MIRROR WHICH WAS CONNECTED BY FOUR WIRES. TWO WIRES WENT TO THE HEATING ELEMENT AND THE OTHER TWO CONTROLLED THE AUTOMATIC DIMMING FEATURE. ON THE INSIDE OF THE DIMMING FEATURE WIRES THERE APPEARED TO BE BLACK RESIDUE. YOU COULD CLEARLY SEE THAT THE MOLDED PLASTIC ON THE BACK OF THE MIRROR HAD MELTED ALONG THE OUTSIDE EDGE (DIGITAL PICTURES AVAILABLE IF NEEDED). I CALLED THE DEALER AND ORDERED A MIRROR THAT ONLY HAD THE HEATED FEATURE WITHOUT THE DIMMING EFFECT. I INSTALLED THIS ON THE LOGIC THAT I COULD LEAVE THE DEFECTIVE WIRES DISABLED. SO FAR EVERYTHING SEEMS TO BE WORKING JUST FINE....

HEATED POWER MIRRORS WITH DIMMING FEATURE HAS A LIQUID INSIDE THAT HAS TURNED DIRTY BROWN RESTRICTING SIGHT REARWARD. THE POWER SWITCH ADJUSTING THE REARVIEW MIRRORS INOP. CD PLAYER INOP. SUNROOF INOP. SUNROOF GETS STUCK INSIDE ITS RAILS IN OPEN POSITION. UNABLE TO OPEN OR CLOSE. ENGINE LEAVES POLLS OF OIL INSIDE MY GARAGE APPROX 1QT. PR 1000 MILES. JUST HAD A CATASTROPHIC TRANSMISSION FAILURE WITH A VERY CLOSE CALL ACCIDENT, LOOSING 3RD AND 4TH GEAR REQUIRING COMPLETE REBUILD OF TRANSMISSION, DRIVE AXLE LEAKING OIL. AND OF COURSE ALL THIS HAPPENS JUST OUT OF WARRANTY. THIS CAR TODAY COSTS $ 50,000.- WITH THIS TRIM PACKAGE. HAS ONLY 81000 ON ODOMETER. GM THIS IS NOT GOOD ENOUGH, SHAPE UP OR SHIP OUT. THIS IS MY 3RD LEMON FROM GM. DO THEY NOT MAKE CARS THAT'LL LAST PAST WARRANTIES ANY MORE?? *JB

WHILE DRIVING OR IDLING THE ELECTRICAL SYSTEM SHUT DOWN INTERMITTENTLY AND CAUSED THE VEHICLE TO STALL. THE VEHICLE WAS TAKEN TO THE DEALER, AND THE DEALER REPLACED THE ELECTRICAL SYSTEM, BUT THE PROBLEM RECURRED. THE DEALER STILL WAS UNABLE TO DETERMINE THE CAUSE OF THE PROBLEM. *AK THE REAR FLOOR PLASTIC PLATE HAD BROKEN, THE LEFT REAR WINDOW MOTOR WAS INOPERATIVE UP AND DOWN, THE DRIVER'S SIDE SEAT WAS COMING APART BY THE DOOR, SEAT TRACK HAD BROKEN, THE RIGHT FRONT SEAT BELT SHOULDER STRAP SOMETIMES TIGHTENED UP, THERE WAS NOISE IN THE REAR END HAD A HARMONIC VIBRATION, THE RIGHT SECOND WINDOW WOULD NOT GO DOWN, THE PASSENGER SIDE SEAT BELT IN THE FRONT LOCKED UP RIGHT FRONT RETRACTOR LOCKED, THE REAR PASSENGER SIDE DOOR SQUEAKS REALLY BAD, THE MOLDING FOR THE RUBBER COMING OFF, AND PASSENGER SIDE FRONT LIGHT HAD COME OUT. *SC

BATTERY WARNING LIGHT COMES ON, VEHICLE ENGINE DIES. CAN BE RESTARTED IN A FEW SECONDS. HAS HAPPENED 2 TIMES IN 3 MONTHS.DEALER DIDNT RECTIFY PROBLEM,THEY ARE PUZZLED.

WE HAVE A 2001 CHEVROLET SUBURBAN. STARTING IN SEPTEMBER 2003, WHEN THE GAS LEVEL GOT TO 1/2, THE GAS GAUGE WOULD DROP TO EMPTY AND THE LOW FUEL LIGHT WOULD GO ON, THEN THE LIGHT WOULD GO OFF AND THE GAS GAUGE WOULD GO BACK TO 1/2. THIS HAPPENED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO THE DEALERSHIP OCTOBER 20, 2003. THEY SAID THEY TESTED, INSPECTED AND RETURNED THE VEHICLE TO ME ON OCTOBER 22, 2003. THEY SAID THEY COULD NOT FIND ANYTHING WRONG AND COULD NOT GET IT TO FAIL AGAIN. ON OCTOBER 26, 2003, THE SAME THING HAPPENED ONLY THE VEHICLE "SHUT DOWN" WITHOUT WARNING. IT COULD NOT BE RE-STARTED AND THE VEHICLE HAD TO BE TOWED TO A DEALERSHIP, THERE THEY" REPLACED PCMB FUSE BLOWN AND FUEL SYSTEM CIRCUIT HAD A SHORT TO GROUND, FOUND WIRES AT MODULE BURNED. THEY REPLACED FUEL MODULE, FUEL PUMP RELAY AND FUSES"....

ELECTRICAL: IF KEY IS TURNED TO ACCESSORY; AFTER APPROXIMATELY 10 MINUTES THE BATTERY IS DRAINED AND CAR WILL NOT START. THIS HAS BEEN GOING ON FOR 3 YEARS EVEN WITH A NEW BATTERY REPLACEMENT. ALSO, FREQUENTLY THE CLOCK DISPLAY WILL BE ON THE WRONG TIME AND LIGHTS FLICKER WHEN USING THE POWER WINDOWS.*AK

STARTING ABOUT THREE WEEKS AGO, OUR 2001 SUBURBAN WOULD "SHUT DOWN" WITHOUT WARNING. IT COULD BE RE-STARTED. THIS HAPPENED 15 - 20 TIMES DURING THESE THREE WEEKS. IT HAS BEEN IN AND OUT OF THE DEALERSHIP DURING THIS PERIOD AND THE PROBLEM COULD BE REPLICATED AT THE DEALERSHIP ON OCCASION. AS OF NOW THERE IS NO CURE AND WORK CONTINUES. IT'S BELIEVED TO BE ELECTRICAL IN NATURE. TO THIS POINT, THE WIRING FROM THE KEY-SWITCH TO THE COMPUTER HAS BEEN BYPASSED, THE ON-BOARD COMPUTER HAS BEEN REPLACED, THE IGNITION MODULE HAS BEEN REPLACED. THE PROBLEM PERSISTS, WITH A POTENTIALLY DISASTROUS OUT COME. *JB

WE OWN A 2001 CHEVROLET SUBURBAN. BEGINNING ABOUT THREE WEEKS AGO THE ENGINE WOULD SHUT OFF WITHOUT WARNING. THIS HAS HAPPENED MANY TIMES. THE VEHICLE HAS BEEN IN THE DEALERS SHOP NEARLY CONSTANTLY FOR THREE WEEKS AND THEY CAN FIND NO SPECIFIC CAUSE OR A CURE FOR THE PROBLEM.
