TL* THE CONTACT OWNS A 2006 HUMMER H3. THE CONTACT STATED THAT THE TEMPERATURE GAUGE HAD INCREASED SEVERAL TIMES AND WHEN HE INSPECTED THE VEHICLE, HE FOUND RADIATOR COOLANT LEAKING FROM THE RADIATOR TOP SEAL. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE HE FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 83,000.
THIS IS THE SECOND TIME THE BLOWER RESISTOR/HARNESS HAS CAUGHT FIRE [1ST TIME 1/11/12 2ND TIME 7/3/13] THE ORANGE WIRE GOING INTO THE HARNESS SEEMS TO OVER HEAT AND MELT/CATCH FIRE THE LAST TIME IT FILLED CAB WITH SMOKE HAD STOP VEHICLE AND EXIT BECAUSE OF FIRE -SMOKE. *TR
VEHICLE HAD HEATER BLOWER HARNESS AND RESISTOR FAIL AND CATCH FIRE FOR THE SECOND TIME. REPAIRED REPLACED ONCE BEFORE. THIS PARTICULAR PROBLEM OCCURS DUE TO A DESIGN DEFECT AND REPLACEMENT PARTS DO NOT CORRECT THE UNDERLYING PROBLEM AND IT WILL FAIL AGAIN. IT IS JUST A MATTER OF TIME. THE CIRCUITS SHOULD BE FUSE PROTECTED SO THIS WILL NOT BURN. PART NUMBERS HAVE BEEN CHANGED TO UPGRADE THIS CONNECTION TO NEWER DESIGN, BUT THESE PARTS ALSO FAIL. THIS IS A SERIOUS FAILURE OF THE ELECTRICAL SYSTEM. IN ADDITION, THE GROUND TERMINAL TO THE CHASSIS (BY THE INTAKE FILTER IN THE ENGINE COMPARTMENT) IS SUSPECT AS WELL. OVERALL THIS IS AN INCREDIBLY NEGLIGENTLY DESIGNED CIRCUIT. ONE CAN ALSO FIND NUMEROUS REPORTED FAILURES IN RELATED VEHICLES USING THE SAME PARTS. *TR
CAME OUT OF WORK TO FIND A PUDDLE OF COOLANT ON THE GROUND. RADIATOR PLASTIC CRACKED. FLUID IS ON FAN AND THROUGHOUT ENGINE COMPARTMENT. SEARCHED ON GOOGLE AND FOUND THIS IS A KNOWN ISSUE. GM DEALER AND CUSTOMER SERVICE ACKNOWLEDGED THIS IS A COMMON ISSUE, HOWEVER WOULD DO NOTHING ABOUT IT. *TR
TL* THE CONTACT OWNS A 2006 HUMMER H3. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE SUN ROOF BEGAN TO LEAK WATER. THE WATER CAUSED MOLD TO GROW INSIDE THE VEHICLE.

THE VEHICLE WAS TAKEN TO A DEALER FOR DIAGNOSIS AND THE CONTACT WAS ADVISED TO CLEAN THE SUN ROOF TRACK EVERY TWO TO THREE MONTHS TO AVOID THE LEAK.THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 68,000.
THE SERVICE TECHNICIAN DIAGNOSED A CRACKED RADIATOR, WHICH IS A KNOW HUMMER H3 ISSUE. THEY HAVE ASKED FOR $850+ TO FIX WHAT IS A KNOWN DESIGN FLAW. HTTP://WWW.HUMMERFORUMS.COM/FORUM/HUMMER-H3-17/READ-IF-YOUR-H3-RADIATOR-HAS-CRACKED-LEAKED-21184/. *TR
I WENT IN TO DEALER FOR WHAT I CALLED A FLUTTERING PERIODIC IDLE. THEY TOOK A LOOK $200.00 LATER TOLD ME I HAD MISFIRE IN #2 AND #5 AND NEEDED NEW HEAD. YOU CAN IMAGINE MY COMMENTS AND HE SAID IT IS COMMON HE JUST DID ONE LAST WEEK ON THE SAME YEAR AND TYPE H3! WELL I WAS IN TOUCH WITH GM - THE CAR IS OUT OF WARRANTY BUT LOW MILEAGE. THEY DID COVER A PORTION AND I WAS RESPONSIBLE FOR THE REST. WELL I PICK UP WEEK LATER. WAS TOLD IT WAS TEST DRIVEN AND RUNS GREAT. I TOLD THEM IT RAN GREAT BEFORE JUST THE FLUTTERING IDLE WHEN I STOPPED AT A LIGHT. THEY SAID YOU ARE ALL SET.. MANY BAD WORDS ESCAPED MY MOUTH WHEN I DROVE HOME AND IT WAS NOT FIXED. THE VEHICLE STILL DROVE THE SAME WAY IT DID BEFORE AND THE FLUTTER WAS STILL THERE,. SO NOW I HAVE TO BRING IT BACK AGAIN AND I MADE THE TECH GET IN THE VEHICLE SO HE KNEW WHAT I WAS TALKING ABOUT AND HE SAID WELL IT WAS BROUGHT IN FOR A MISFIRE. UHHH NO IT WAS NOT. WHY HAS GM NOT DONE ANY TYPE OF RECALL ON THIS IF IT IS KNOWN PROBLEM. FEEL LIKE THEY DON'T CARE SINCE THE VEHICLE IS NOT MADE ANYMORE WHAT DOES IT MATTER TO THEM. I COULD CONTINUE BUT AM LIMITED TO CHARACTERS. *TR
TL* THE CONTACT OWNS A 2006 HUMMER H3. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 10 MPH, A BURNING ODOR WAS SMELLED AND SMOKE EMITTED FROM THE GLOVE COMPARTMENT.

WE HAVE BATTLING THE PROBLEM OF THE SUNROOF LEAKING ON OUR HUMMER. THERE IS DRAIN TUBES IN THE CORNERS OF THE SUNROOF THIS WATER IS SUPPOSED TO GO DO THESE TUBES THEN ON THE GROUND. HOW EVER THIS IS NOT THE CASE. IN MOST CASES THE WATER LEAKS DOWN THE PILLARS IN THE TRUCKS DASH COMPARTMENT AND SOAKS THE CARPET ON BOTH SIDES AND THE HEAD LINER. WE HAVE HAD IT TO THE DEALERSHIP ON SEVERAL ACCESSIONS AND THEY JUST SAY THEY WERE STOP UP BUT THEY JUST LEAK THE NEXT DAY LIKE NOTHING HAS EVEN BEEN DONE. THEY CHARGE 300 DOLLARS TO DO THIS. I HAVE THE TECHNICIAN TELL ME THAT NOTHING HE HAS DONE WILL FIX THIS OFF THE RECORD..WHEN THE WATER IS POURING IN THERE IS NOTHING YOU CAN DO THE ONSTAR GOES OFF AND YOUR LIGHTS ON THE INSIDE GO DIM WE HAVE HAD THE CPU SHORT OUT DUE TO WATER THE BLOWER CONTROLLER BOTH FRONT SPEAKERS AND BEHIND THE DASH ALL THE METAL PARTS ARE COVERED IN RUST. WHEN THE ELECTRICAL PARTS SHORTED OUT THE WIRES WERE BURNT AND WE WERE DRIVING WHEN THIS HAPPENED ON ONE OCCASION AND HAD TO HAVE IT TOWED. WE HAVE TRIED EVERYTHING TAKEN IT THE DEALERSHIP DID NOT HELP. THE TRUCK IS ALWAYS DAMP INSIDE. THEN OF COURSE THE SMELL OF THE CARPETS. I EVEN HAVE CONTACTED GM AND JUST SAID TAKE TO THE DEALERSHIP AND THEY ARE GONNA CHARGE THE SAME THING. I AM SCARED FOR MY WIFE AND FAMILY TO DRIVE THIS TRUCK. WE WILL NOT EVEN LEAVE IN THE GARAGE DUE THE RISK OF FIRE. IF YOU GOOGLE THIS PROBLEM THERE IS OVER 60K TOPICS ON THIS AND FORUM AFTER FORUM ABOUT IT. AND EVERY IS SAYING THIS. IT
I HAVE OWNED THIS TRUCK SINCE 2009, AND IT SEEMS TO BE A COMMON PROBLEM WITH THE SUNROOF DRAIN TUBES CLOGGING. WHEN MY VEHICLE WAS UNDER WARRANTY, AND WAS GOING IN FOR IT'S SCHEDULED PMIS I WOULD HAVE THEM BLOW THE DRAIN TUBES OUT WITH AIR, BUT THE CLOGGING IS NOW BECOMING MORE FREQUENT, AND THE WATER IF NOT REMOVED CAN CAUSE HAVOC WITH THE CLOTH, ELECTRICAL & FLOORING. LAST WEEK I HAD A MILDEW SMELL BECAUSE OF ALL THE RAIN WE HAVE HAD, AND THE WATER BUILT UP IN THE SUNROOF DRAIN AREA. THESE TUBES ARE A DESIGN FLAW, AND THIS SHOULD ALSO BE A RECALL, AS THE WATER WILL BE THE MAIN CAUSE FOR PROBLEMS IN THIS SITUATION. *TR
RADIATOR RUBS IN THE MIDDLE ON THE FRAME CAUSING STRESS TO THE TOP, CRACKLING CRACKS . .CAUSING LEAKAGE!! *TR
THE CHECK ENGINE LIGHT WENT ON AND OFF. THE VEHICLE WAS TAKEN TO A MECHANIC WHO DIAGNOSTIC AS CYLINDER #1 MISFIRE. COMPRESSION TEST FAILED DUE TO CYLINDER LEAKAGE. THE MAIN PROBLEM WAS TO AT THE TIME OF MANUFACTURING THE ENGINE SOFT METALS WERE USED WITH THE HEADS. I WAS TOLD I NEED TO REPLACE CYLINDER HEAD AND RELATED PARTS. CONTACTED GM HUMMER DIVISION INFORMED THEM OF MY PROBLEM WITH MY 3.5L, 5 CYLINDER ENGINE AND ASK THEM FOR ASSISTANCE SINCE THEY DID A SPECIAL EXTENDED WARRANTY FOR THE 2006 COLORADO AND CANYONS WITH THE SAME ENGINE PROBLEMS. THEY REFUSED TO HELP. *TR
WAS DRIVING WITH 50 MPH AND TRAFFIC STOPPED SO I HAD TO PRESS THE BRAKES A LITTLE HARDER. AT THAT POINT BOTH REAR LEAF SPRINGS FAILED, DAMAGING DRIVE SHAFT AND PULLING DRIVESHAFT FROM THE TRANSFER CASE. REPAIRS FOR ALL THIS WERE $2700. *TR......UPDATED 09-03-14 *BF UPDATED 09/8/2014 *JS
MY VEHICLE HAS A CRACKED RADIATOR AND ACCORDING TO OTHER HUMMER OWNERS THIS IS A COMMON DEFECT THAT HAPPENS TO THESE VEHICLES. *TR
THIS WILL BE THE THIRD BLOWER MOTOR RESISTOR THAT I HAVE HAD TO REPLACE. THIS TIME I AM REPLACING THE HARNESS BECAUSE IT BURNED UP SO BADLY ON TWO TERMINALS. GM HAS YET TO ACKNOWLEDGE THIS PROBLEM... I PAID $26 FOR THE RESISTOR, AND IT'S GOING TO BE $30 FOR THE HARNESS, AND I SAVE A TON ON THE LABOR BECAUSE I AM A MECHANIC, BUT THIS IS A POTENTIAL FIRE HAZARD. THERE IS AN AIR FLOW IN THIS AREA, AND CAN FAN OR START FLAMES IN THIS AREA IF IT OCCURS WHILE DRIVING. VERY DANGEROUS! THIS IS MY SECOND REPORT. *TR

WHILE DRIVING MY 2006 HUMMER H3 ON A BACK COUNTRY PAVED RD, DOING THE POSTED SPEED LIMIT, MY SIDE CURTAIN AIR BAGS ON BOTH SIDES DEPLOYED FOR NO REASON. THE ROAD HAD ITS BUMPS AND STUFF LIKE ANY ROAD BUT NOTHING TO CRAZY. THE VEHICLE WAS NOT IN A CRASH OR ROLLING OVER AND SHOULD NOT HAVE DEPLOYED AIRBAGS. THIS SITUATION COULD HAVE BEEN DEADLY, THANK GOD IT WASN'T. GM IS SENDING OUT A THIRD PARTY INSPECTOR TO LOOK AT THE VEHICLE. I HAVE A FEELING THIS WILL END UP IN COURT. THERE HAS BEEN MANY OF THESE CASES AND GM HAS NOT CORRECTED WITH RECALL OR NOTHING. SOMETHING NEEDS TO BE DONE AND FORCE THEM TO DO THE NEEDED RECALL ON THIS. *TR
BLOWER MOTOR FOR HVAC STOPPED WORKING, SMELLED BURNING PLASTIC, WIRING AND RESISTOR BURNED UP. IT IS LOCATED UNDER THE DASH AND IS VERY EASY TO CATCH FIRE, THERE ARE MANY COMPLAINTS ON THIS WITH THE CHEVY & GM PRODUCT. I THINK THIS SHOULD BE A RECALL IT IS VERY DANGEROUS AS MANY ITEMS CAN BURN UP, GM IS OF NO HELP WITH THIS. *TR
AS I WAS LEAVING WORK THE OTHER DAY, MY HUMMER H3 LOST ITS A/C. AS I CHECKED IT OUT I FOUND THAT THE A/C PUMP WOULD TURN ON, BUT THERE WAS NOTHING BLOWING THRU THE VENTS. AS I DID AN INTERNET SEARCH I FOUND A BLOG REGARDING THIS VERY PROBLEM, IT SEEMS TO BE AN ISSUE WITH A RESISTOR AND CONNECTOR IN THE BLOWER SYSTEM. IT MELTS AND BECOMES USELESS. THIS IS NOT ONLY AN INCONVENIENCE AT 100 PLUS DEGREES, IT IS A FIRE HAZARD AS WELL. I BELIEVE THIS NEEDS TO BE LOOKED INTO. *TR

THIS HAS ACTUALLY HAPPENED SEVERAL TIMES. WATER DRAINAGE FOR THE SUNROOF SYSTEM GET CLOGGED REALLY EASILY AND FAST. WATER WILL SPILL OUT FROM WATER TRAY AND WILL RUN OVER THE CEILING AND FALL THROUGH THE ROOF MIC (USED FOR ONSTAR), LOCATED DIRECTLY ABOVE THE DRIVER'S FACE. WHEN DRIVING AND TURNING, WATER WILL MOVE SIDE WAYS AND IT WILL SPILL THROUGH THE MIC AND SUNROOF WINDOW INTERIOR OPENING, SOAKING THE DRIVER WHILE DRIVING. NOT SAFE AT ALL. DRAINAGE DESIGN IS FLAW, AND IT KEEPS CLOGGING AFTER FIXING IT. *TR

ENGINE LIGHT CAME ON DURING EMISSION TESTING, WHICH CAUSED THE VEHICLE TO FAIL. JUST HAD THE THERMOSTAT AND EVAPORATOR VALVE REPLACED THE WEEK BEFORE. THE EMISSIONS DEPARTMENT STATED THAT IT WAS A CODE P0300, MISFIRE IN CYLINDER 1. I TOOK THE VEHICLE FOR DIAGNOSTICS AND AFTER A COIL TEST AND COMPRESSION TEST (FAILED), THEY STATED THAT IS WAS A CYLINDER VALVE LEAKAGE. THEY ALSO STATED THAT THERE WAS A BULLETIN OUT ON 2006 H3 FOR THIS ISSUE. WHEN I CONTACTED GM CUSTOMER SERVICE, I WAS TOLD THAT THE VEHICLE'S VIN WAS NOT A PART OF THIS BULLETIN AND THAT THE MILEAGE WAS PAST THE WARRANTY. THE ONLY THING THEY COULD SUGGEST TO ME IS TO TAKE IT TO A GM CERTIFIED REPAIR FACILITY AND I WOULD HAVE TO PAY FOR THE COMPLETE REPAIR MYSELF. *TR
THE CHECK ENGINE LIGHT GOES OFF AND ON INTERMITTENTLY. THE VEHICLE WAS TAKEN TO A MECHANIC WHO PERFORMED A DIAGNOSTIC THAT LOCATED THE FAILURE AT THE ENGINE HEAD CYLINDER. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND DENIED ASSISTANCE WITH THE REPAIR BECAUSE THE VEHICLE WARRANTY WAS EXPIRED. THE MECHANIC STATED IT WAS DUE TO AN INFERIOR SOFT METAL USED TO MANUFACTURE THE HEADS WHICH CAUSED A LOSS OF COMBUSTION WHEN THE ENGINE WAS IDLING. THE BLOWBACK AT IDLE WAS WHAT WAS CAUSING THE ENGINE LIGHT TO ILLUMINATE. MECHANIC ALSO STATED THIS PROBLEM WAS A RECURRING PROBLEM IN THIS 5CYL ENGINE WHICH IS THE SAME ENGINE THAT IS IN THE COLORADO PICKUPS AND IS COVERED UNDER A GM RECALL IN THE PICKUPS BUT NOT THE HUMMER. THE MECHANIC STATED THAT THE ISSUE WILL ONLY GET WORST. PLEASE HELP AS I WAS GIVEN A PRICE TO REPAIR OF APPROX. $4000 IF I WAS GOING TO PAY FOR THE REPAIRS MYSELF AT THE DEALERSHIP. *JS

DEFECTIVE CYLINDER HEAD FROM GMC - THEY KNOW ABOUT THIS PROBLEM BUT WON'T ASSIST WITH COST TO REPAIR, MY H3 AT 50,000 MILES NOW HAS CRACKED CYLINDER HEAD FOR NO APPARENT REASON AND OF COURSE SINCE MY WARRANTY IS NO LONGER IN EFFECT I HAVE NO RECOURSE. IS THERE NOTHING THAT CAN BE DONE ABOUT THIS? *JS
VERY VERY COMMON PROBLEM WITH GM PRODUCTS AND EXCESSIVE PROBLEM WITH H3 HEATERS. YOU SMELL SOMETHING BURNING IN YOUR VEHICLE THEN YOUR HEATER FAN STARTS FLUCTUATING AND ULTIMATELY STOPS. THERE ARE REPORTS THAT THE DEALERSHIP WILL FIX THE BURNT PLUG, BUT IT WON'T FIX THE PROBLEM, IT'LL BURN UP AGAIN. NOW I HAVE NO HEATER IN JANUARY IN OHIO THIS SHOULD BE A RECALL !!!!!!!!! *TT

AFTER HEAVY RAIN EXCESSIVE AMOUNTS OF WATER POOL INSIDE VEHICLE. DRAIN PLUGS HAVE BEEN CLEANED OUT MULTIPLE TIMES. ALTHOUGH WATER CONTINUES TO LAY INSIDE THE TRACK OF THE MOON ROOF AS WELL AS DRAIN ONTO THE FLOOR AND SOMETIMES ONTO THE DRIVER'S SIDE SEAT (DEPENDING ON HOW THE VEHICLE IS PARKED). BASED ON THE FORUMS REGARDING H3'S THIS APPEARS TO BE A COMMON PROBLEM. WHY HASN'T GM DONE ANYTHING TO RESOLVE IT??? *TR
THE BLOWER ON MY 2006 HUMMER H3 STOPPED WORKING WHILE DRIVING DOWN THE HIGHWAY AND WE SMELLED A BURNT PLASTIC SMELL WHEN THE BLOWER STOPPED. THE SMELL EVENTUALLY WENT AWAY, BUT THE BLOWER NEVER WORKED AGAIN. I FOUND THAT THIS IS A HUGE ISSUE FOR NOT JUST HUMMER OWNERS, BUT OTHER GM VEHICLE OWNERS. THE RESISTOR AND PLASTIC CLIP WERE MELTED TOGETHER AND WHEN DISCONNECTED, FIRE DAMAGE WAS EVIDENT. THIS RESISTOR FOR THE AC BLOWER IS LOCATED RIGHT UNDER THE GLOVE COMPARTMENT AND LUCKILY NOTHING FLAMMABLE WAS CLOSE TO THIS WHEN IS BLEW WHILE DRIVING DOWN THE HIGHWAY.

ON OCTOBER 30TH I SMELLED A FAINT SCENT OF SOMETHING BURNING INSIDE MY VEHICLE, BUT COULD NOT FIND ANYTHING. NOVEMBER 1ST WAS OUR FIRST COLD MORNING SO I STARTED MY CAR, AND HAD NO HEAT. THE SYSTEM WASN'T BLOWING, BUT THE HEATER A/C CONTROLS WERE LIT UP. SINCE I AM A MECHANIC, AND HAVE KNOWLEDGE I WENT RIGHT TO THE FUSE BOX IN THE ENGINE COMPARTMENT. THE FUSES WERE OK. I THEN WENT TO THE BLOWER RESISTOR PACK WHICH IS LOCATED UNDER THE GLOVE BOX. THE ORANGE POWER WIRE IN THE HARNESS WAS BURNT UP PRETTY GOOD, AND THE TERMINAL MOLDED INTO THE HARNESS PACK WAS ALSO BURNED UP PRETTY GOOD. I THEN WENT ONLINE TO GOOGLE THIS PROBLEM TO SEE HOW COMMON IT WAS, AND WAS SURPRISED TO SEE HOW MANY COMPLAINTS THERE ARE ABOUT THIS PROBLEM, NOT JUST REGARDING THE HUMMER LINE, BUT WITHIN GM VEHICLES ITSELF. I CALLED THE SERVICE TECH WHERE I HAVE MY WORK DONE, AND HE WAS VERY FAMILIAR WITH THIS FAILURE. *TR

AS I WAS DRIVING TO MY OFFICE FROM A LUNCH BREAK, MY A/C AND VENTILATION STOPPED WORKING, I TURNED THE ON AND OFF DIAL AND AIR NEVER CAME BACK ON, SHORTLY AFTER THAT A STRONG "BURNED" SMELL CAME FROM THE GLOVE BOX OF MY VEHICLE, I PULLED OVER AND NOTICED A LITTLE BIT OF SMOKE COMING FROM UNDERNEATH THE GLOVE BOX. I DID SOME RESEARCH ON THE INTERNED AND DISCOVERED IT WAS A BURNED OUT "VENT BLOWER RESISTOR" (AC DELCO PART# 15-80647) I HAVE SINCE REPLACED IT BUT IT STILL NOT WORKING. I HAVE THE BURNED PART IF EVER NEEDED, I MUST SAY I DON'T FEEL AT ALL SAFE WITH A SITUATION LIKE THIS AS IT HAS NEVER HAPPENED TO ME. I DECIDED TO INCLUDE MY COMPLAINT AS I HAVE SEEN MANY PEOPLE WITH THE SAME PROBLEMS ON THIS VEHICLE, A FIRE IS EMINENT AND SHOULD BE PREVENTED.
A/C HEATER MOTOR RESISTOR OVERHEATED CAUSING SMOKE THROUGHOUT THE PASSENGER COMPARTMENT ON THE HIGHWAY THIS IS THE THIRD REPLACEMENT OF THIS PART, THE WIRING OVERHEATS AND MELTS THE CONNECTORS THIS IS A VERY COMMON PROBLEM ON HUMMERS OF ALL TYPES. MY SISTER OWNS AN H3 AS WELL AND HAS HAD TO REPLACE THIS TWICE ON HER 2007 MODEL H3 DUE TO OVERHEATING AN MELTING THE CONNECTOR. IS GENERAL MOTORS GOING TO WAIT UNTIL THERE ARE NUMEROUS FATALITIES OR VEHICLE FIRES TO RECTIFY THIS ? A FIRE IN THE PASSENGER COMPARTMENT WHILE AT HIGHWAY SPEEDS IS DANGEROUS TO SAY THE LEAST

H3 |DRAINAGE PROBLEM I PAID TO HAVE IT FIXED A YEAR AGO AND IT IS BLOCKED UP AGAIN. MY WIFE HAD THE SAME PROBLEM WITH HER H3. I HAVE HAD CARS AND TRUCKS AND HAVE NEVER HAD THIS PROBLEM BEFORE WITH THERE SUN ROOFS. I KNOW I'M NOT THE ONLY ONE OUT HERE THAT'S HAD THE SAME PROBLEM . WHEN AT THE DEALERSHIP ONE OF THE SHOP MECHANICS SAID THE DESIGN WAS A POOR CONSTRUCTION AND DESIGN.THE COMPANY SHOULD BE DOING SOMETHING ABOUT THERE DESIGN AND FIX IT OR HAVE A PROGRAM TO KEEP THEM FROM FLOODING . IT COULD LEAD TO ELECTRICAL PROBLEMS . DO TO THE WATER RUNNING DOWN OVER THE LOWER PANELS. I'M NOT HAPPY PAYING TO HAVE IT FIXED AGAIN. THIS IS JUST A BAD DESIGN ON GM PART. *TR
NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
