GMC Complaints

TRANSMISSION SHIFT FROM 1ST GEAR. THERE IS A PROBLEM IN THE GEAR SHIFT FROM 1ST TO 2ND IT SLAMS THE TRANSMISSION WHEN YOU STOP AND START. THERE IS A HEATER IN THE TRANSMISSION THAT PUTS EXTRA DEGRADATION ON THE OIL CAUSING IT TO NEED REPLACEMENT VERY EARLY. DEALER KNOWS OF THE ISSUE BUT HAS NO FIX FOR IT ONLY STATED THEY NOTED THE FILE IN CASE IT FAILS. UNACCEPATABLE FOR A 55,000. PLEASE LOOK INTO THIS.

TL* THE CONTACT OWNS A 2012 GMC ACADIA DENALI. THE CONTACT STATED THAT THE VEHICLE OFTEN DECELERATED INDEPENDENTLY AND WOULD NOT EXCEED 30 MPH. ALSO, THE DOORS WOULD UNLOCK AND "SERVICE STABILIZER BAR AND SERVICE TRACTION DEVICE" APPEARED ON THE INSTRUMENT PANEL. THE VEHICLE WAS TAKEN TO AUTONATION OF LAUREL (500 WASHINGTON BLVD, LAUREL, MD 20707, (866) 255-2985) WHERE IT WAS DIAGNOSED THAT A NEW WIRING HARNESS NEEDED TO BE INSTALLED. THE VEHICLE WAS REPAIRED. TWO WEEKS LATER, THE REPAIR FAILED. THE VEHICLE WAS TAKEN BACK TO THE DEALER THREE TIMES FOR REPAIRS AND WAS CURRENTLY WAITING ON ANOTHER REPAIR REGARDING THE TRANSMISSION'S MODULAR HARNESS. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURES. THE FAILURE MILEAGE WAS 89,000. THE VIN WAS UNKNOWN.

DASHBOARD CRACKED AT PASSENGER AIR BAG AND AT INSTRUMENT CLUSTER BROKEN PLASTIC PIECES WILL BECOME SHRAPNEL DURING AN ACCIDENT AND AIR BAG INFLATION

THIS IS THE SECOND COMPLAINT I HAVE MADE HAS STILL HAVE NOT HEARD ANYTHING. THIS IS SAD THAT IT HAS NOT BEEN DEALT WITH. I HOPE MY FAMILY IS NOT IN A SERIOUS ACCIDENT BECAUSE OF THIS CAR.

THIS HAS BEEN THE MOST UNSAFE CAR I HAVE EVER OWNED. I CAN NOT EVEN TRADE IT IN THE GET A SAFER CAR. WE HAVE COME SO CLOSE TO HAVING MANY ACCIDENTS WITH THIS CAR. THE STEERING JUST FREEZES UP THE ENGINE WILL JUST SHUT DOWN WILL DRIVING. WE HAVE HAD THE TRANSMISSION REPLACED ONCE AND NOT IT NEEDS REPLACED AGAIN. WE ARE NOT HARD ON OUR CARS..I JUST HOPE IT DOES NOT COME DOWN TO HAVING A ACCIDENT BEFORE SOMEONE SEES HOW BAD THIS CAR IS.. THIS HAPPENS OFF AND ON ALL THE TIME HARD TO PUT THE DATES AND TIMES DOWN WHEN THIS HAPPENS, WE TAKE INTO A DEALER AND IT DOES NOT HAPPEN WITH THEM OR THE COST IS JUST CRAZY.

2015 GMC SIERRA SLE / 60K MILES / PROJECTOR HEADLIGHTS...NUMEROUS COMPLAINTS FROM NUMEROUS OTHERS, I'M IN THE SAME BOAT. ILLUMINATION IN GENERAL, DRIVING IN RURAL AREAS, DRIVING IN INCLEMENT WEATHER, MAKING TURNS (SIDE STREETS), ETC., IS HORRIBLE, UNSAFE, NERVE-RACKING AND TROUBLESOME. SURE, THE HEADLIGHTS LOOK SNAZZY, BUT PERFORM ABOUT AS WELL AS MY LAWN TRACTOR'S HEADLIGHTS. I SEE THERE'S A TSB REGARDING THE SITUATION AND, MUCH TO MY DISMAY, I HAVE TO PAY FOR SAID PARTS/LABOR TO CORRECT AN OBVIOUS DESIGN FLAW/SNAFU. AM I CRAZY FOR THINKING THIS IS UNACCEPTABLE? EVEN MORE SHOCKING, IT APPEARS THE BCM REPROGRAMMING (MARGINAL RESULTS) AND LAMP REPLACEMENT IS PROBLEMATIC (INCREASED VOLTAGE TO A BULB/LAMP SHORTENS ITS LIFE CONSIDERABLY). A VEHICLE THAT COSTS 30-40-50K SHOULD NOT HAVE GARBAGE TECHNOLOGY. ON THE PLUS SIDE, AT 48 YEARS YOUNG, MY VISION REMAINS 20/20 AND I DO NOT REQUIRE VISION CORRECTION. THE WIFE, MY 2 KIDS (OF DRIVING AGE) AND MY NEIGHBOR CONCUR - THESE HEADLIGHTS SUCK. I LOVE EVERYTHING ELSE ABOUT THE VEHICLE, BUT IT LOOKS LIKE INSTEAD OF SPENDING $200 FOR THE TSB, I'LL TRY MY LUCK WITH AFTERMARKET REPLACEMENTS FOR $300. VIA MULTIPLE ONLINE VEHICLE FORUMS, MOST WHO'VE GONE THE ROUTE OF TSB ARE MARGINALLY IMPRESSED AND EVERYONE ELECTING TO GO WITH AFTERMARKET IS COMPLETELY SATISFIED...THAT ALONE SHINES A SPOTLIGHT ON THE LACK OF VISIBILITY BOTH THE NHTSA AND GM ARE PROVIDING THE CONSUMER. MAYBE INSTEAD OF PAYING SUITS MILLIONS PER YEAR TO PRODUCE SUBPAR VEHICLES, GM SHOULD DO THE RIGHT THING AND FOCUS ON WHAT MATTERS MOST -- THE PAYING CUSTOMER. YEAH, WE HAVE A BETTER SHOT WITH THE NHTSA HOLDING GM ACCOUNTABLE AND FORCE THEM INTO A RECALL (CORRECTING THE PROBLEM PROPERLY, NOT A WILLY NILLY REPROGRAM AND BULB REPLACEMENT).

THE TAIL LIGHTS ARE FAULTY. THIS IS THE SECOND TIME I'VE HAD AN LED TAIL LIGHT GO OUT. SECTIONS OF THE LIGHTS COME ON AND OFF. ONE TAIL LIGHT ASSEMBLY HAS BEEN REPLACED ALREADY. THEY ALSO GET CONDENSATION ON THE INTERIOR OF THE ASSEMBLY. THIS APPEARS TO BE A COMMON THEME FOR A TAIL LIGHTS ON GM SUV'S FROM 2015-2018. THESE LIGHTS CAN BE PURCHASED FOR ANYWHERE BETWEEN $400. TO $900 RANGE FOR JUST ONE! THEY ARE ON A VEHICLE WHICH HAS A BASE PRICE OF OVER $50K AND LAST LESS THAN TWO YEARS! COME ON!

TAKATA RECALL AIRBAG LIGHT IS ON . TRUCK WILL SHUT DOWN WHEN THE TRUCK IS GOING DOWN THE ROAD AT 60 MILES AN HOUR LESS OR MORE. WHEN YOU START THE TRUCK IT SHUTS OFF AGAIN. OR WILL START RIGHT UP AND WASH IT RIGHT BACK DOWN. THE SAFETY BELT LIGHT COMES ON OR IS THE CAR LOCKED I SHOULD SAY. WHICH IS THE LITTLE PICTURE WITH THE CAR WITH THE LOCK ON IT. I HAVE VIDEOTAPED WHAT COMES ACROSS THE DASH AND HASN'T SHOWN IT TO THE DEALERSHIP AND THEY HAVE NOT DONE ANYTHING BECAUSE THEY CAN'T FIND ANYTHING. SHUTS OFF AGAIN. OR WILL START RIGHT UP IN THE SHUT RIGHT BACK DOWN. SAFETY BELT LIKE COMES ON OR IS THE CAR LOCK I SHOULD SAY. WHICH IS THE LITTLE PICTURE WITH THE CAR WITH THE LOCK ON IT. I HAVE VIDEOTAPED WHAT COMES ACROSS THE DASH AND HIS SHOWING IT TO THE DEALERSHIP AND THEY HAVE NOT DONE ANYTHING BECAUSE THEY CAN'T FIND ANYTHING. ALL OF THIS IS GOING ON RIGHT NOW WITH MY TRUCK AND HAS BEEN SINCE LATE FALL OF LAST YEAR. I TAKE IT TO MY DEALERSHIP TWICE WITH NO RESULTS . *TR

DASH IS CRACKED AT THE CORNER OF THE AIRBAG AND IN FRONT OF THE INSTRUMENT PANEL

I BEGAN DRIVING MY 2013 GMC TERRAIN DOWN THE STREET AND MY CAR BEGAN TO FEEL AS IF IT WAS GOING TO STALL. THEN THE CHECK ENGINE LIGHT CAME ON & A FEW MINUTES LATER, THE ENGINE BLEW WITH 126,000 MILES ON THE CAR. PRIOR TO THIS DAY, THE CAR HAD BEEN OPERATING WITHOUT ANY ISSUES AND NO WARNING LIGHTS HAD COME ON. THE MECHANIC SAID THAT THE TIMING CHAIN HAD BROKEN & THERE WAS NO OIL IN THE ENGINE. I BOUGHT THIS CAR NEW & WAS THE ONLY OWNER & RELIGIOUSLY CHANGED MY OIL EVERY 5,000 MILES & WAS NOT YET DUE FOR AN OIL CHANGE. SINCE THIS HAS HAPPENED, I DISCOVERED THAT THERE HAVE BEEN SEVERAL COMPLAINTS ABOUT THIS VEHICLE IN REGARD TO OIL CONSUMPTION ISSUES & THERE HAS NOT BEEN A RECALL ISSUED. THIS POSES A SERIOUS SAFETY CONCERN ESPECIALLY CONSIDERING AN OIL WARNING LIGHT NEVER CAME ON NOR, DID ANY WARNING LIGHTS UNTIL IMMEDIATELY PRIOR TO THE ENGINE BLOWING.
