2005 Chevrolet Suburban 1500 Electrical 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 RUBBER HOSE, WATER MAY HAVE BEEN LEAKING ONTO THE ELECTRICAL WIRING/CONNECTIONS WHEN I USED THIS FEATURE TO CLEAR DIRT FROM THE LIFT GATE WINDOW, BUT I DON'T REALLY KNOW FOR SURE IF THAT IS HOW THE DAMAGE TO THE WIRING HARNESS HAS OCCURED! THANKS!

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 THEM. A VEHICLE SHOULD START WITH ONE TRY. I SHOULD NOT HAVE TO GET THE FUEL PRESSURE GOING IN THE ON POSITION, OR CRANK IT TWICE FOR MY TRUCK TO START.

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 ISSUED A TSB FOR THIS PROBLEM BUT THE RECOMMENDED FIX (REPROGRAMMING THE DRIVER DOOR SWITCH) ACTUALLY DOES NOT FIX THE PROBLEM. IN FACT, WHEN THE DEALER REPROGRAMMED MY GMC IT ACTUALLY MADE IT WORSE TO WHERE IT HAPPENS MUCH MORE FREQUENTLY. I CONTACTED GM AND EVEN THOUGH I TOOK IT TO A DEALER 4-5 MONTHS AGO WHERE THEY COULDN'T FIX IT, GM SAYS I HAVE TO TAKE IT BACK TO THE DEALER (PAY ANOTHER $100 DIAGNOSTIC FEE) TO MEET THEIR POLICY THAT THEY WILL ONLY ADDRESS THE ISSUE IF YOU'VE BEEN TO A DEALER WITHIN THE LAST 30 DAYS. SOME REPORTS ARE THE SEAT HEATER ELEMENTS ARE SHORTING OUT. EITHER WAY THIS CREATES A VERY UNSAFE SITUATION FOR DRIVERS. GM SAYS I CAN PULL THE FUSE FOR THE SEAT HEATERS. HOWEVER, WHEN YOU REMOVE THE FUSE LABELED "SEAT HEATER" IT ACTUALLY DOES NOTHING. THE SEATS ARE STILL POWERED AND THE PROBLEM PERSISTS. THIS CLEARLY INDICATES AN ELECTRICAL PROBLEM AND DESIGN FLAW. THE ONLY SURE CURE IS TO REMOVE THE 30 AMP BREAKER UNDER THE DASH RENDERING YOUR DRIVER/PASSENGER INOPERATIVE. GM MUST FIX THIS PROBLEM BEFORE SOMEONE GETS KILLED FROM BEING DISTRACTED. *TR

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 UP CHEVY FIX THIS. *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

I HAVE A CHEVY SUBURBAN 2005 MY SPEEDOMETER HAS STOPPED WORKING. I ALSO HAVE A 2005 DURAMAX THAT THIS HAS HAPPENED TO. I WOULD LIKE TO SEE A FULL BLOWN RECALL PLACED ON ALL GMC/CHEVY VEHICLES. APPARENTLY THESE ARE HUNDREDS OF THOUSANDS PEOPLE WITH THIS ISSUE ACROSS THE U.S./ WORLD ACCORDING TO FORUMS I HAVE BEEN ON. WHILE THERE IS A CLASS ACTION LAWSUIT OUT THERE FOR A VERY LIMITED GROUP OF GMC VEHICLES, MAKING LAWYERS RICH. INSTEAD OF TAKING CARE OF THE PEOPLE WHOM MAKE THIS WORLD ACTUALLY RUN. THIS ISSUE NEEDS TO SERIOUSLY LOOKED INTO. MY NEXT STEP IS TO GET THE MEDIA INVOLVED SHOWING HOW AGAIN THE AVERAGE CONSUMER CAN GET SCREWED BY THE BIG COMPANIES. I AM NOT KEEPING MY MOUTH SHUT ABOUT THIS. THANK YOU *TR

2005 CHEVY SUBURBAN ODOMETER IS FAULTY. IT STOP WORKING PROPERLY ON MY CHEVY TRUCK. IT OVERSHOOT THE SPEED ALL THE WAY TO MORE THAN 120MILES/HR WHEN I DO NOT GO OVER 30MILES/HR. GM NEEDS TO TAKE OWNERSHIP OF IT. NEEDS TO HAVE RECALL. IT IS SAFETY OF GENERAL PUBLIC. PLEASE FORCE THEM TO RECALL FOR THE ODOMETER. *TR

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

I HAVE A 2005 CHEVROLET SUBURBAN Z71 WITH 59,799 MILES. THE SPEEDOMETER ON IT RECENTLY STOPPED WORKING CORRECTLY. THE DAY THE SPEEDOMETER STOPPED WORKING CORRECTLY I WAS ON AN HOUR LONG TRIP ON THE HIGHWAY. DURING THE TRIP I NOTICED THE SPEEDOMETER SHOWED I WAS GOING 95 MPH. THE SPEEDOMETER CONTINUED TO INCREASE EVEN WHEN I SLOWED DOWN, UNTIL IT PASSED 120 MPH WHERE IT WAS STUCK FOR SEVERAL DAYS. IT STARTED TO SLOWLY GO BACK DOWN. SINCE THAT DAY THEN THE SPEEDOMETER CONTINUES TO SHOW THE INCORRECT SPEED OF THE VEHICLE. THE SPEEDOMETER SOMETIMES READS AS HIGH AS 120 MPH WHEN THE VEHICLE IS NOT MOVING, AND AT OTHER TIMES DISPLAYS THE VEHICLE GOING 10 MPH WHEN THE VEHICLE IS NOT MOVING, AND OTHER TIMES SHOWS CORRECTLY AT 0 MPH. THE PROBLEM SEEMS TO GET WORSE WHEN I DRIVE THE VEHICLE ON LONGER TRIPS. I HAVE CONTACTED THE LOCAL DEALERSHIP AND WAS TOLD THERE IS A RECALL TO CORRECT THIS PROBLEM BUT THAT MY VIN NUMBER IS NOT INCLUDED IN THE RECALL. *JB *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
