2005 CHEVROLET SUBURBAN 1500 Electrical System Problems

I NOTICED CORRODED AND WHAT I WOULD CALL CHARRED OR BURNT WIRING ON THE WIRING HARNESS FOR THE REAR LIFT GATE OF MY SUBURBAN. I NOTICED IT WHEN I OPENED THE LIFT GATE TO GAIN ACCESS TO THE REAR OF THE SUBURBAN. IT APPEARS THAT THE RUBBER GROMMET MATERIAL PROTECTING THE WIRING HARNESS, WAS BURNT OR MELTED AWAY. THE RUBBER HOSE THAT SUPPLIES WATER TO THE REAR WINDOW WASHER/WIPER HAD A HOLE IN IT, AND MAY HAVE BEEN LEAKING WINDSHIELD WASHER FLUID ONTO THE WIRES FOR A TIME. THE WIRES WERE BARE IN SOME SPOTS, SOME OF THE WIRE INSULATION LOOKED MELTED/BURNT AWAY, AND THEY LOOKED CORRODED/WITH A GREEN COLOR TO THEM. THE CONNECTOR THAT CONNECTS THE HARNESS, TO THE REST OF THE ELECTRICAL SYSTEM, LOOKED LIKE IT HAS SOME BLACK/ POSSIBLY BURNT RESIDUE ON IT. I CAN TAKE A GUESS AT BEST, THAT BECAUSE OF THE HOLE IN THE...

2005 CHEVROLET SUBURBAN 1500 4X4 FLEX FUEL, 5.3L. THIS VEHICLE'S INSTRUMENT CLUSTER DOES NOT WORK. TACHOMETER PEGS AND STICKS. THE SPEEDOMETER IS STUCK AT ZERO. THIS IS A VERY SERIOUS SAFETY CONCERN THAT GENERAL MOTORS/GM SHOULD DO A FREE RECALL FOR AS MANY OWNERS OF THIS VEHICLE HAVE THE SAME PROBLEMS. MY ABS SENSOR LIGHT COMES ON AND OFF NUMEROUS TIMES A DAY, AND CLUSTER STATES SERVICE AIR BAG. GENERAL MOTORS SHOULD ALSO FIX THIS FOR FREE UNDER A RECALL AS OTHERS HAVE THE SAME ISSUE WITH THIS VEHICLE. MY THIRD MAJOR COMPLAINT, IS THE VEHICLE STARTING PROBLEM/HARD START. IT TAKES TWO TURNS OF THE ENGINE FOR THE VEHICLE TO TURN ON AND STAY RUNNING. I HAVE RESEARCHED THIS ON VARIOUS SEARCH ENGINES, FORUMS, AND INCLUDING RECALL.GOV. GENERAL MOTORS SHOULD ADDRESS THIS ISSUES AS WELL UNDER A RECALL. GM INSTALLED FAULTY FUEL PUMPS OR FUEL PUMPS WITH FAULTY COMPONENTS IN...

THE DRIVER SIDE SEAT HEATER RANDOMLY TURNS ITSELF ON. WHEN YOU TURN IT OFF IT COMES BACK ON AGAIN AND RANDOMLY CYCLES THROUGH THE VARIOUS SETTINGS. IT'S ALMOST A CONSTANT BATTLE TRYING TO KEEP IT TURNED OFF WHICH CREATES A HAZARDOUS SITUATION EQUAL TO, OR WORSE, THEN TEXTING WHILE DRIVING AS YOU HAVE TO KEEP LOOKING DOWN TO PUSH THE BUTTON, ESPECIALLY HERE IN FLORIDA WHERE YOU DON'T NEED (OR WANT) SEAT HEAT IN THE SUMMER. I'VE FOUGHT THIS TO THE POINT THAT I'VE WORN THE PAINT OFF THE SWITCH. IF YOU SEARCH THE INTERNET THIS IS A VERY PREVALENT PROBLEM WITH GM VEHICLES DURING THESE MODEL YEARS. I ALSO HAVE A 2006 GMC SIERRA THAT DOES THE EXACT SAME THING. I'VE BEEN TO AT LEAST 5 DIFFERENT DEALERSHIPS AND EITHER THEY CAN'T FIX IT OR THEY CLAIM THEY'VE NEVER HEARD OF THE PROBLEM. THAT CAN'T BE TRUE SINCE GM...

I WAS DRIVING ON A TRIP TO FLORIDA WHEN AT 65 MPH MY SPEEDOMETER KEPT INCREASING AND PEGGED OUT AT THE 120 MPH MARK. I PULLED OVER TO TRY AND RESOLVE THE ISSUE BUT TO NO AVAIL IT STAYED STUCK AT THE 120 MPH MARK. WHEN I RESTARTED THE VEHICLE ALL MY CLUSTER GAUGES WERE PEGGED OUT: OIL, BATTERY, TEMP, AND EVEN GAS GAUGE. I ALSO STARTED GETTING INFO THAT MY AIRBAG SYSTEM NEEDED ATTENTION. FOUR WHEEL DRIVE LIGHT CAME ON JUST A DIFFERENT ARRAY OF MALFUNCTIONS CAME FLYING ACROSS MY DISPLAY. TO THIS DATE MY BATTERY GAUGE IS STILL PEGGED OUT MY AIRBAG LIGHT IS ON, SERVICE FOUR WHEEL DRIVE LIGHT STILL FLASHES INADVERTENTLY AND NOW MY DRIVERS SIDE HEATER AND CONTROLS ARE NOT WORKING CORRECTLY. BROUGHT IN TO REPAIR SHOP & THEY SAID NO RECALL HAS BEEN ISSUED SO MY COST WOULD RUN WELL OVER $1500.00. RIDICULOUS. OWN...

ELECTRICAL CLUSTER SPEEDOMETER WENT HAYWIRE THEN QUIT ODOMETER DID THE SAME. *TR

SPEEDOMETER VERY ERRATIC, SHOWS EXCESSIVE SPEEDS (120MPH) OR DOESN'T REGISTER CORRECT SPEED AT ALL. CALLED DEALER NUMEROUS TIMES ABOUT PROBLEM AND NEVER TOLD ABOUT THE TSB ONLY THAT IT WOULD BE OVER $600 TO FIX. DID RESEARCH ONLINE AND FOUND TSB AND CALLED AGAIN. THIS IS A HUGE SAFETY HAZARD AND ONE THAT CHEVROLET SHOULD ADDRESS ACROSS THE BOARD WITH THE VEHICLES AFFECTED BY THIS. THEN WAS TOLD CAN'T FIX IT BECAUSE OF MILEAGE UNLESS I PAY OUT OF POCKET. NOW NEEDLE IS STUCK AT ZERO AND UNFORTUNATELY BEING MILITARY WE DON'T GET PAID ENOUGH TO JUST SHELL OUT $600+ ON A WHIM. SOMEONE NEEDS TO MAKE CHEVROLET TAKE CARE OF THEIR FAULTY PRODUCTS, IF YOU PAY FOR A PREMIUM PRODUCT YOU SHOULD GET ONE. *TR

A/C SYSTEM WOULD RANDOMLY BLOW HOT AIR; THEN FAN WOULD RUN WITH IGNITION OFF; THEN FAN SPEEDS WOULD QUIT WORKING; FINALLY BLOWER QUIT ALTOGETHER. GM HAS 2 SERVICE BULLETINS OUT WITH EXACT PROBLEM DESCRIPTION, BUT THEY CLAIM MY VEHICLE NOT COVERED. *JS

AT 99K MILES THE SPEEDOMETER STARTED ACTING ERRATIC. THERE ARE TIMES IT IS CORRECT AND TIMES WHEN IT READS 5 TO 25 MILES MORE THAN MY TRAVELING SPEED. IT IS DEFINITELY HIT OR MISS AS TO WHEN THIS WILL OCCUR. NOW THE OIL PRESSURE GAUGE AND THE RPM GAUGE ARE ACTING FAULTY AS WELL. I HAVE NOT TAKEN ANY MEASURES TO CORRECT THE SPEEDOMETER BUT IT WILL RESET ITSELF AFTER SEVERAL TIMES OF TURNING THE CAR ON AN OFF. THIS IS DEFINITELY A SAFETY HAZARD WHEN THE SPEEDOMETER READS ERRANTLY WHILE DRIVING ON THE INTERSTATE. *TR

SPEEDOMETER ON OUR 2005 SURBURBAN HAS BEEN MALFUNCTIONING LIKE ALL OTHERS REPORTED ON THIS SITE - OURS FOR WELL OVER TWO YEARS: SOMETIMES READS ZERO WHEN DRIVING AT HIGHWAY SPEEDS, OTHER TIMES IS TACKED AT OVER 120 MPH. WE CAN BE AT A STOP AND IT READS 90. AFRAID TO USE CRUISE CONTROL - WHO KNOWS WHAT WILL HAPPEN! WAITING FOR NHTSA TO DEMAND A RECALL THESE VEHICLES: WHAT WILL IT TAKE? SOMEONE DYING BECAUSE THEY HYDROPLANE, OR ROLL, OR REAR END SOMEONE BECAUSE THEY HAVE NO CLUE HOW FAST THEY ARE GOING? *TR

WE OWN A 2005 CHEVY SUBURBAN, AND THE SPEEDOMETER BEGAN TO JUMP AROUND AND ACT ERRATICALLY. IT NOW SHOWS ABOUT 60 MPH, EVEN THOUGH THE VEHICLE IS AT A STOP. GOES UP ABOVE 120 MPH WHILE DRIVING THROUGH TOWN. WE CALLED THE DEALERSHIP, AND JUST LIKE OTHERS REPORTED, WAS TOLD WE WERE GOING TO BE TAKEN FOR OVER $600 FOR A REPAIR THAT IS OCCURRING IN VIRTUALLY EVERY 2005 GM TRUCK (ALONG WITH OTHER YEARS). WE CAN NO LONGER TELL WHAT SPEED WE ARE DRIVING, WHICH IS A SERIOUS SAFETY HAZARD, ESPECIALLY FOR MY TEENAGE DRIVERS THAT DRIVE THIS VEHICLE. *TR

2005 CHEVY SUBURBAN THE SPEEDOMETER JUST WENT OUT @ 42,600K MILES. *TR

TL* THE CONTACT OWNS A 2005 CHEVROLET SUBURBAN 1500. THE CONTACT STATED HE NOTICED WHILE DRIVING 30 TO 40 MPH THAT THE SPEEDOMETER READ 120 MPH, AND WHEN DRIVING 70MPH THE SPEEDOMETER READ 0 MPH. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED. THE DEALER ADVISED THE CONTACT THAT THE INSTRUMENTAL CLUSTER PANEL FAILED. THE MANUFACTURER ADVISED THAT BECAUSE THE VEHICLE WAS OVER THE EXTENDED WARRANTY COVERAGE, THEY WOULD NOT ASSIST WITH THE REPAIR. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 68,000 AND THE CURRENT MILEAGE WAS 69,000.

SPEEDOMETER NOT WORKING PROPERLY, EVEN WHEN THE CAR IS STOP IT SHOW 70 MPH. *TR

2005 CHEVY SUBURBAN SPEEDOMETER FAILURE. WHILE DRIVING HIGHWAY SPEED SPEEDOMETER STOPPED INDICATING CORRECT SPEED, INDICATED 120 MILES PER HOUR. SPEEDOMETER IS NOT WORKING AT ALL. *TR

ON A HIGHWAY TRIP HOME, THE SPEEDOMETER GOT STUCK AT 73MPH AND STEADILY INCREASED IN SPEED UNTIL IT JUST POINTS DIRECTLY DOWNWARD. IT STAYS FACING DOWNWARD AND DOESN'T MOVE AT ALL NO. THE CHEVY DEALERS ALSO SAY THAT THERE IS A RECALL BUT OUR CARS VIN NUMBER DOESN'T MEET THE RECALL. THEY AGREE CHEVY SHOULD REPAIR THE VEHICLE. WHEN I CONTACTED CHEVY, THEY TOLD ME THE WOULD OFFER NO ASSISTANCE AND TO STOP CONTACTING THEM REGARDING THE PROBLEM. *TR

JUST GOT INTO MY 2005 CHEVY SUBURBAN 1500. THE SPEEDOMETER STOP WORKING. REGISTERING 100MPH WHILE I WAS AT A STOP LIGHT, NOT WORKING AT ALL WHILE I DROVE BACK TO THE HOUSE. THERE IS A LAWSUIT FOR 2004 MODELS AND ONLY UP TO 70,000MILES. THIS IS A CLUSTER FAILURE AFFECTING THOUSANDS OF SUBURBAN,TAHOE, AND SIMILAR MODEL OWNERS. THE DEALERSHIPS ARE CHARGING AN AVERAGE OF $450.00 TO REPAIR THIS DEFECT THAT, JUDGING FROM THE LAWSUIT IS A COMMON PROBLEM. IT AFFECTS MY MONITORING OF MY SPEED AND ENDANGERS THE PUBLIC AND ALSO PUTS DRIVERS IN A BAD POSITION WITH LAW ENFORCEMENT. GM IS OBLIGATED TO REPAIR A PROBLEM THAT THEY HAD KNOWLEDGE OF. THERE ARE TOO MANY OF THESE VEHICLES ON THE ROAD TO ALLOW THIS DEFECT AND POTENTIAL SAFETY ISSUE TO GO UNCHECKED. *TR

WE HAVE A 2005 CHEVROLET SUBURBAN WITH 50,000 MILES. OUR INSTRUMENT CLUSTER IS NOT WORKING PROPERLY. SPEEDOMETER IS STUCK, OTHER GAUGES (I.E. FUEL, OIL, TEMP) WORK INTERMITTENTLY. I BELIEVE THIS IS A HUGE SAFETY ISSUE FOR OBVIOUS REASONS! THE COST TO FIX THIS IS $650 AND AFTER MUCH RESEARCH I SEE MANY COMPLAINTS OF THE SAME NATURE! CHEVROLET HAS EVEN RECALLED THE 2003/2004 MODELS FOR THIS REASON! WHY NOT 2005? *TR

SPEEDOMETER SHOWS 110 MPH WHEN CARS ARE PASSING ME. I BELIEVE AM GOING ABOUT 55 OR 60 MPH. I UNDERSTAND THE PROBLEM IS WITH THE INSTRUMENT CLUSTER IN THE DASHBOARD. *TR

I HAVE A 2005 CHEVY SUBURBAN WITH ABOUT 55,000 MILES ON IT. FOR THE PAST 6-8 MONTHS, MY SPEEDOMETER AND OTHER GAUGES (OIL, ETC.) WILL STICK CAUSING INACCURATE READINGS. AT TIMES MY SPEEDOMETER IS ABOUT 30 MPH OFF FROM THE REAL SPEED, AND FOR THE MONTHS THE OIL GAUGE HAS READ OFF THE CHARTS. *TR

MY DAUGHTER WAS DRIVING DOWN THE ROAD AND SPEEDOMETER BEGAN ACTING ERRATICALLY. AT A STOP LIGHT SPEEDOMETER READS 25 MPH. IGNITION WAS TURNED ON/OFF WITH NO RESULTS. *TR

THE SPEEDOMETER IN MY 2005 CHEVROLET SUBURBAN HAS DEVELOPED A TICKING NOISE IN THE PAST FEW DAYS. THE VEHICLE HAS 83, 300 MILES. IT STARTED AS A LOW CLICKING NOISE AND HAS CONTINUED TO BECOME LOUDER. I HAVE CONTACTED THE LOCAL CHEVROLET DEALERSHIP, WHICH GAVE ME NO SATISFACTION FOR REPAIRS. *TR

INSTRUMENT CLUSTER FAILURE. GAUGES NOT ACCURATE. I WAS TOLD INSTRUMENT CLUSTER WOULD NEED TO BE REPLACED AT MY COST. *TR
