2015 GMC SIERRA 1500 Unknown Or Other Problems

I am on my 4th radiator and 3rd thermostat. August will be 1 year ! 2014 models are covered 2015 (like mine) is not covered. Transmission has shifted like crab since day of purchase 3 years ago. I am told it is a known issue from the factory with no solution. Truck also had a weird tick sense day one which turned into 2 failed valve springs. I have had 2 ball joints FAIL 1st time a month after purchase in my driveway. Second time 2000 miles later same side on my street

The truck has only 122, 230 miles and shuddering in the transmission is horrible. I just purchased the truck 3 weeks ago and the owner stated nothing was wrong with it. However I took it to mechanic for inspection after purchase and he stated transmission has shuddering. I noticed at 40 miles plus the truck vibrates at steering wheel.

My air conditioner doesn't work and vehicle is a 2015 GMC truck.

I was driving my GMC Sierra upon entering the highway, I was at a stop sign waited for clear traffic when it became safe to do so, I entered the highway and upon excelling up a small incline the vehicle transmission just completely stopped working so as I depressed the accelerator the engine would would wind the RPMs up but the vehicle wasn't going anywhere. I pulled the car over to the side of the road and placed the car in park. Put my emergency lights on and couldn't get the truck to the to go to the area to be free and clear of traffic to transmission engage. I put the car into reverse this is the second time this has happened and this is what my husband recommend I do. When I called him is to place the vehicle in reverse reverse a little bit and then place the car into park and then turn it off. Start the car up again and see if it would engage the gear, it took placing the vehicle in park. After adjusting the steering column and trying it again, the transmission engaged but would not reach the full acceleration. I was on a hill so I put the brakes on and the car brakes would not stop the vehicle. It would bounce and skid a bit as I was on an incline. The transmission was not engaging in reverse either. After resting then it didn't get any speed. There are RPMs just kept whining out. I wasn't able to at first get the car to go into gear after wiggling or adjusting the steering column then it seemed to go in gear but it would only go a few feet and then it the process would start over. this was dangerous as I was on a highway with an incline which means I had no break ability so I was rolling without control. I was able to get the car home and parked in my driveway but as this is the second event that has happened since we purchased the truck I'm making this report. Feel free to contact me if needed

Service Trailer Brake System warning keeps coming on every time I start my truck.

I have not yet been notified by the manufacturer regarding the recalls on the vehicle.

I was driving and my nephew says there was smoke in the truck then all of a sudden there was a huge pop and my rear passenger window shattered! I had found online that this has happened to several people but there is no recall in the US. Something to do with the remote start putting on the defrost and the connection exploding. If this is happening a lot i believe it should be replaced.

On 9/22/2020 a recall service was performed on my defroster/ power sliding rear window under N192265660. On 1/13/2022 I was driving down the road with the rear defroster on, a smell of burning plastic and a low hissing noise. I was in the process of pulling over to inspect this and the back window of my pickup burst, sending me swerving onto the side of the road. I booked an appointment with the dealer, they are telling me they cannot replace this since the recall was already serviced. Obviously the fix GM is putting into our vehicles is as dangerous as the original design. This needs to be remedied and GM needs to be held accountable, bursting rear windows can cause terrible accidents, luckily I am safe.

My back window just made a loud pop sound. I have a back window that had an electic sliding widow. Which means the back window is in 3 sections (driver side, middle sliding window, and passenger side). The driver side of the back window was completely shattered. It's hard to see from the outside but from the inside it is spider cracked everywhere. I believe that I had my rear defrost on at the same time. Nothing hit my window to cause this.

Alert of “service trailer brake system” keeps beeping and alerting many times while driving

transmission. just like others with this year and mine went out .i was going like 50-55mph and i almost got into a accident while my son was with me . truck started sputtering and shifting up and down check engine light, stabilitrack, and something else, my truck seemed like it was down shifting and not going into gear, rpms were going from 1000 to 2000 and truck was shaking and started making a howling noise. it felt like i had a misfire in a way. its available for inspection, i

While operation my 2015 GMC 1500 DENALI Pickup at normal conditions my vehicle produced a engine light. I was three blocks from my office so I proceeded there immediately to have my vehicle scanned for codes. This is where I found out that cylinder #7 had an issue. This cylinder is part of the AFM system. I had the vehicle towed to Galles Chevrolet for diagnostic services and an estimate for repairs. Up receiving the results (which) I will attach. Bank 1 and possibly Bank 2 lifters and springs have failed. Thus possibly cause damage to the cam shaft. While I am aware that my vehicle is out of powertrain warranty (5 years / 100,000 mile), my vehicle only has 52,000 miles on it and very very well taken care of at all times. I am also aware of a class action law suite that pertained to the same exact issue on gm products from 2004-2014. Also service bulletins were produced by GM pertaining to this issue. Now I have been out of service of my vehicle for 3 1/2 weeks not to mention a potential $7000 repair, that should have never been in the picture! Poor quality control on products for potential profit gains have cost many many customers pain, anguish, and money.

I was towing a camper down Rt 422 in Butler, PA in my GMC truck when it suddenly caught fire. My wife was following me and alerted me to pull over as quickly as possible. I had no brakes and the gear shifter went straight up without shifting. The doors would also not open while the truck was filling with smoke. I got out using the manual unlock knob and am lucky to be alive. We had about one minute to try to extinguish the flames before it fully engulfed both my truck and camper. I filed a complaint with GMC. By what I am reading online there are many instances of fires and GMC does not seem to provide assistance. This is very unnerving and scary to say the least. I am sad and angry for this situation. This happened through no fault of my own and I lost absolutely everything. I was in the middle of moving to start a new job and lost many work items in my truck as well. I had to delay my start date for work. Now I am responsible for deductables, insurance increases and other items not covered by my insurance. Now I have to buy a new vehicle and camper but what will GMC do to help me? Probably nothing.

WHILE DRIVING, A MESSAGE POPS UP ON THE DISPLAY THAT READS: "WARNING TAKING YOUR EYES OFF THE ROAD TOO LONG, OR TOO OFTEN WHILE USING THIS SYSTEM COULD CAUSE A CRASH, RESULTING IN INJURY OR DEATH TO YOU OR OTHERS. FOCUS YOUR ATTENTION ON DRIVING" SERIOUSLY, WHEN A WARNING MESSAGE POPS UP, WE READ IT! I HAVE GOTTEN USE TO THIS STUPIDITY AND JUST HIT OK. BUT EVEN AT THAT, YOU STILL GET DISTRACTED. PROBLEM NOW, IS THAT EVEN HITTING OK DOES NOT CLEAR IT. THIS MESSAGE SHOULD NEVER HAPPEN. I HAVE READ THAT THIS A BIG ISSUE AMONG MANY GMC AND CHEVY OWNERS. GM IS LITERALLY CREATING THE SAFETY HAZARD.

REAR WINDOW DEFROSTER STARTED SMOKING AND CREATED A BURNING PLASTIC SMELL. AFTER TURNING OFF THE REAR DEFROSTER THE REAR WINDOW EXPLODED/SHATTERED IN PLACE. I SEE THERE IS A RECALL IN CANADA, BUT NOT HERE. THIS IS HAPPENING HERE AND I HAVE READ OF MANY OTHERS WITH SAME ISSUE. FIRE AND BROKEN GLASS IS NOT SAFE AND SHOULD BE ADDRESSED

VEHICLE WAS STATIONARY ON THE STREET, PARKED. I ENTERED IT, AND TURNED ON MY FRONT AND REAR DEFROSTERS WITH THE SETTING ON "HI." I TURNED AROUND AND VERIFIED THAT MY VEHICLE HAD NOT BEEN HIT NOR WAS ANY DAMAGE AT ALL APPARENT TO ME. AT SOME POINT AS I SAT THERE WITH THE CAR IDLED AND THE HEATED AIR REACHING ITS MAXIMUM TEMPERATURE, I BEGAN TO SMELL SOME FOUL SMELL IN THE CAB THAT I BELIEVED WAS EXHAUST ENTERING THE CABIN. I ROLLED DOWN THE WINDOW. AS I BRUSHED THE SNOW FROM THE FRONT AND BEGAN TO DRIVE AWAY, I HEARD A NOISE THAT I BELIEVED WAS THE SNOW FALLING FROM THE ROOF. HOWEVER, AS I ROLLED AWAY, I NOTICED A LOUDER-THAN-NORMAL CABIN. UPON LOOKING BEHIND ME, I NOTICED THE REAR RIGHT WINDOW WITHIN THE SLIDING REAR CABIN WINDOW HAD BLOWN OUT. UPON INSPECTING THE AREA, I NOTICED THAT NO SNOW OR WATER WAS PRESENT INSIDE. GIVEN THAT WE HAD RECEIVED A LOT OF SNOW THE PREVIOUS EVENING THROUGH THE MORNING, HAD THE DAMAGE OCCURRED THROUGHOUT THE EVENING OR EARLY MORNING, THERE WOULD'VE BEEN MOISTURE PRESENT.

THE VEHICLE ALWAYS HAS A SMELL OF DAMPNESS AFTER A RAIN. SOMEHOW WATER IS GETTING INTO THE VEHICLE. I HAVE REPLACED THE SEAL AROUND THE THIRD-BRAKE LIGHT WHICH WAS THOUGHT TO BE THE CULPRIT, BUT NO FIX. THE REAR SEAT METAL HAS RUST ON THEM FROM THE DAMP. THE DRIVER'S SEAT CREAKS WHEN MAKING TURNS. IT IS LIKE IT ABOUT TO COME APART. THERE SHOULD BE A RECALL ON THIS. PEOPLE COULD GET HURT IF IT HAPPENS. LE UNDER THE VEHICLE, I NOTICED THAT A BODY-MOUNT IS MISSING UNDER THE DRIVER'S SIDE. THIS COULD BE THE REASONS FOR THE CREAKING. I AM NOT SURE!

SYMPTOM OF HOT AIR BLOWING WHILE USING THE A/C, STATIONARY OR WHILE OPERATING. FILLED WITH COOLANT WHICH ONLY LASTED ABOUT ONE WEEK. REVIEWED FORUMS AND TSB'S TO NOTE A COMMON ISSUE WITH THE CONDENSER. DEALER WANTED TO DIAGNOSE AND REPLACE ITEMS IN ORDER THAT DID NOT INCLUDE REPLACING THE CONDENSER AT THE TOP OF THAT LIST. PURCHASED A THIRD PARTY CONDENSER, VACUUM PUMP, AND NECESSARY FLUIDS AND ACCESSORIES AND REPLACED BY MYSELF. A/C HAS BEEN WORKING RELIABLY FOR SEVERAL MONTHS. ALTHOUGH I SAVED ABOUT 2K DOLLARS (ALL MATERIALS COST ABOUT 500 HUNDRED DOLLARS), IT'S CLEAR THAT THIS ISSUE IS KNOWN AND SHOULD BE A RECALL.

I BOUGHT THIS NEW ON JAN 3, 2016 ON JULY 26 26, 2019 WHILE FROM WACO TO FT. WORTH TEXAS, MY AC COMPRESSOR SEIZED AND BLEW DESTROYED THE SERPENTINE BELT. I HAD TO REPLACE THE AC COMPRESSOR AND BELT. 31,000 MILES BUT OUT OF WARRANTY. LAST WEEK I WAS DRIVING HOME FROM WORK AND FELT THE AC WAS AGAIN BLOWING HOT AIR. I TOOK IT IN AND TODAY 06/29/20 I HAVE TO REPLACE THE AC CONDENSER AS IT HAS A LEAK AT A WELD POINT. I HAVE READ DOZENS OF COMPLAINTS THAT THIS IS A KNOWN ISSUE AND DEFECT. I WILL NOW BE OUT OVER $2,000 FOR A KNOWN PROBLEM AND ISSUE. I HAVE READ THE TSB, WATCHED NEWS REPORTS AND ON-LINE FORUMS. THE TECH AT MY DEALERSHIP SAID THIS IS A SUPER COMMON PROBLEM WITH THESE VEHICLES. THAT SEEMS LIKE IT WOULD LEAD TO A RECALL. *TR

THERE IS A LEAK ON THE TOP RIGHT HAND SIDE OF THE A/C CONDENSER RESULTING IN HOT AIR COMING OUT OF THE VENTS WHEN THE A/C IS ENABLED. AFTER SOME RESEARCH I FOUND THAT THIS IS A COMMON ISSUE AND GM HAS TO TAKE RESPONSIBILITY FOR IT. GM ALREADY ISSUED A TSB FOR THE 2015 - 2017 TAHOES, YUKONS, AND ESCALADES WITH THE SAME ENGINES AND EQUIPMENT AS MY 2015 GMC SIERRA WITH 45000 MI.

WHAT HAPPENED TO THE YUKON A/C ISSUE HAPPENED TO ME. WHAT WOULD IT TAKE TO MAKE SURE THE SIERRA HAS THE SAME RECALL AS THE YUKON? "YUKON AND YUKON XL VEHICLES, MAY HAVE A CONDITION WHERE THERMAL CYCLING ON THE COMBINATION TRANSMISSION FLUID/OIL AND AC CONDENSER COOLER CREATES A CRACK THAT MAY ALLOW REFRIGERANT TO ESCAPE. THIS CONDITION CONSEQUENTLY MAY DEACTIVATE THE AC SYSTEM WHICH MAY CAUSE POTENTIAL CUSTOMER ANNOYANCE."

TORQUE CONVERTER. ME AND ALONG WITH 4 OTHER PEOPLE ARE HAVING PROBLEMS WITH IT. UPON START UP AND DRIVING IT STARTS TO GET SLUGGISH AND THEN JUST COMES ALMOST TO A COMPLETE STOP ONLY BUILDING RPM'S ACCRODDING TO THE GM DEALERSHIP IT'S NORMAL. WITH ALL THE GMC TRUCKS I'VE OWNED IT HAS NEVER DONE THIS. AND IS ONLY STARTING TO DO IT OVER THE PAST COUPLE OF MONTHS. I'VE TALKED TO A GUY WHO JUST HAD 2 REPLACED IN HIS TRUCK AND IS CONTINUING TO HAVE THE PROBLEM. TO AVOID ANY VEHICLE DAMAGE FOR ANYONE ELSE I'M CONSIDERING IF YOU CAN CHECK AND SEE IF ANYONE ELSE IS HAVING THE ISSUE. I TAKE VERY GOOD CARE OF MY TRUCK I DON'T MUD IN IT OR DRIVE IT CRAZY(WRECK LESS). DEALERSHIP IS ALSO PRETTY MUCH REFUSING TO LOOK INTO THE PROBLEM OR DIAGNOSING IT CONSIDERING THAT IT'S 'NORMAL' FOR THE TRUCK DO THAT. WHICH I STRONGLY DISAGREE.

I TURNED ON THE REAR DEFROSTER, AND MY DAUGHTER SAID "MOM, IT'S SIZZLING." I LOOKED BACK AND THERE WAS SMOKE ON THE REAR WINDOW. THEN THERE WAS A LOUD BANG, AND IT SHATTERED. THE VEHICLE WAS NOT IN MOTION AT THE TIME. I WAS JUST GETTING READY TO BACK OUT OF THE PARKING AREA IN MY DRIVEWAY.

I HAVE A 2015 GMC SIERRA WITH 95,198 MILES ON IT. THE AC STARTED BLOWING HOT AIR WHEN I WAS DRIVING TO WORK. I PURCHASED AND INSTALLED AN AC REFILL KIT, WHICH ONLY LASTED A COUPLE OF HOURS. I TOOK MY TRUCK TO THE LOCAL GM DEALERSHIP TO DIAGNOSE PROBLEM. DEALERSHIP CALLED TO TELL ME THAT IT WOULD BE $800+ TO REPLACE AC CONDENSER. UPON FURTHER INVESTIGATION I DISCOVERED THAT FAULTY AC CONDENSERS, AND COMPRESSORS ARE VERY COMMON PROBLEMS IN CERTAIN GMC, CHEVY, AND CADILLAC VEHICLES. WHY ARE CONSUMERS STUCK PAYING OUT OF POCKET FOR KNOWN DEFECTS THAT ARE IN EXCESS OF $800?

THE AIR CONDITIONING STARTED BLOWING HOT AIR WHILE MOVING. THE TRUCK IS ONLY 4 YEARS OLD WITH 75000 MILES ON IT. IN DOING RESEARCH WE HAVE LEARNED THAT THIS IS A COMMON PROBLEM WITH THE GMC SIERRA'S AND IT NOT COVERED BY GM EVEN THOUGH IT APPEARS TO BE A DESIGN FLAW.

GMC HAS COVERED THIS ISSUE FOR LIKE SUV MODELS (ESCALADE, TAHOE, YUKON), BUT WANTS OVER $1,000 TO REPAIR GMC SIERRA 1500 AT GMC DEALERSHIP. THIS IS A FAULTY PRODUCT DESIGN THAT IS A KNOWN PROBLEM PER THEIR OWN SERVICE BULLETIN, AND ASSOCIATED HARNESS TO ENFORCE FAULTY AIR CONDITIONER UNIT DESIGN.

LIKE SO MANY OTHERS, MY TRUCK IS NOT VERY OLD AND HAS BEEN BLOWING HOT AIR FOR MONTHS. IT APPEARS TO BE THE SAME CONDENSER ISSUE AS REPORTED BY HUNDREDS IF NOT THOUSANDS MORE. AFTER DISCOVERING THIS IS CHRONIC ISSUE AND AC DELCO * DISCONTINUED THE ORIGINAL CONDENSER * ISSUED TSBS FOR THE CONDENSER WHICH INCLUDE A BRACKET TO HELP PREVENT THE ISSUE (TSB PIT5331 / OCT 2014) (TSB PIE0340 / MAY 2015) NEITHER OF THESE WERE EITHER APPLIED TO MY VEHICLE OR WERE NOT EFFECTIVE IN PREVENTING THE ISSUE. IT SEEMS OBVIOUS THAT THIS IS A DEFECT IN MATERIALS AND WORKMANSHIP BASED ON THEIR ISSUING OF THESE TSBS AND FAILURE TO RECALL THESE VEHICLES UNDER WARRANTY. THEY'VE APPARENTLY OPERATED A BLATANT "LET'S WAIT AND SEE" CAMPAIGN, HOPING THOSE OF US THAT DIDN'T CATCH THIS UNDER WARRANTY WILL FALL OUT OF WARRANTY AS I HAVE. SEVERAL LAW FIRMS HAVE INITIATED CLASS ACTION SUITS AGAINST GM IN REGARDS TO THIS, BUT IT SEEMS LIKE THAT'S A GOOD CHANCE TO GET LAWYERS RICH AND NOT GET MY TRUCK FIXED, OR GET A CHECK FOR $9.99... AS A SUMMARY - MY TRUCK BEGAN BLOWING WARM AIR LAST FALL, BUT I DIDN'T RECOGNIZE IT AS AN ISSUE AS THE WEATHER WAS ALSO TURNING COOL AND I WASN'T USING THE A/C. AC/DELCO AND GENERAL MOTORS KNOWS THIS IS CHRONIC AND AVOIDABLE ISSUE THE FAULTY PARTS HAVE BEEN REPLACED WHEN THE PRODUCTS FAIL UNDER WARRANTY NO EFFORT HAS BEEN MADE TO REPLACE THE KNOWINGLY FAULTY PARTS.

MY 2015 GMC SIERRA 1500 (APPROXIMATELY 45,000 MILES) HAD A DEFECT THAT CAUSED THE AC SYSTEM TO CRACK AND LEAK REFRIGERANT, LOSE PRESSURE, AND FAIL TO PROPERLY FUNCTION. WHEN I TOOK MY VEHICLE TO A CERTIFIED GM SERVICE CENTER ON 4/11/19, THREE OTHER SIMILAR VEHICLES (MAKE/MODEL/YEAR) WERE EXPERIENCING THE SAME ISSUE. UPON CONDUCTING FURTHER RESEARCH I FOUND THAT THIS ISSUE IS WIDESPREAD AMONGST SIMILAR YEAR GMC SIERRA AND CHEVROLET SILVERADO 1500 PICKUPS. SO MUCH SO THAT SOME AREAS ARE EXPERIENCING AC CONDENSER REPLACEMENT PART SHORTAGES. MY VEHICLE WAS NO LONGER UNDER WARRANTY AND GM REFUSED TO ASSIST WITH THE OVER $1,200 REPAIR BILL.

WHEN I FIRST TOOK IT IN WITH THE PROBLEM, THE DEALERSHIP CALLED ME AND SAID ALL FIXED, BUT IT DID IT BEFORE I LEFT THE PARKING LOT. THEY HAD MY TRUCK ALL DAY FOR THE ISSUE, PUT ME OUT OF A VEHICLE AND THEN SAID THEY WOULD NEED FOR EXTENDED TIME TO REPAIR BUT DIDN'T KNOW THERE WAS PROBLEM.

THIS POST IS ABOUT MAKING THE PUBLIC AWARE OF A POTENTIAL PROBLEM. ALTHOUGH THE MANUFACTURER DID NOT STEP UP AND DO THE RIGHT THING, I'M CONCERNED OTHERS MAY HAVE DEALT WITH THIS PROBLEM OR IT MAY HAPPEN IN THE FUTURE. ON AUGUST 29, 2018, MY TRUCK WAS PARKED ON MY DRIVEWAY BY 4PM AFTER RUNNING ERRANDS FOR A COUPLE OF HOURS. AT 6PM MY HUSBAND WENT OUT TO GET SOMETHING OUT OF IT AND SAW IT HAD CAUGHT ON FIRE. NOTHING WAS LEFT PLUGGED IN AND THERE WAS NOTHING FLAMMABLE IN THE TRUCK. THE FIRE DEPT WAS CALLED AND UPON INSPECTION STATED THE FIRE HAD STARTED IN THE CENTER CONSOLE AND SPREAD TO THE FRONT PASSENGER SEAT. THE CAUSE OF THE FIRE LOOK TO BE WIRING THAT OVERHEATED INSIDE THE CONSOLE WHERE THE WIRING CONNECTED TO 2 USB PORTS. GM INSPECTED THE DAMAGE AND FOUND THERE WAS NOT A MANUFACTURER DEFECT AND THE CAUSE OF THE FIRE WAS FROM AN EXTERNAL SOURCE. IRONICALLY, THEIR 3RD PARTY "EXPERT" FIRE INVESTIGATOR WAS NOT AWARE THERE WAS A WIRING HARNESS LOCATED BEHIND THE USB PORTS AND HAD TO BE SHOWN THEIR LOCATION. MY INSURANCE COMPANY IS NOW INVESTIGATING THE INCIDENT. I'M ASKING THEM TO LOOK INTO THE 12V POWER OUTLET POSSIBLY OVERHEATING AS I KNOW OF SOMEONE WHO HAD THEIRS OVERHEAT IN THEIR 2018 CHEVY SILVERADO. THE DAY AFTER THE FIRE I SENT PHOTOS TO THEM AND THEY COULD NOT BELIEVE THE DAMAGE. WHEN I TOLD THEM THE OUTCOME OF GM'S INVESTIGATION THEY WERE DUMBFOUNDED. I'M FORTUNATE NO ONE WAS HURT, BUT AM AFRAID THIS MAY HAPPEN TO SOMEONE ELSE. I MADE A 40K + INVESTMENT WITH GM AND LITERALLY "WAS BURNED". I WANT OTHER TO BE AWARE OF THE POTENTIAL FIRE DANGER. I DID EXPECT GM TO STEP UP AND TAKE CARE OF THEIR LOYAL CUSTOMER (I'VE BOUGHT 8 GM VEHICLES), BUT IT APPEARS THE ALMIGHTY DOLLAR WON OUT. THANKFULLY, IN MY CASE, NO ONE WAS HURT.

AC CONDENSER UNIT STARTS LEAKING AND VEHICLE AC STOPS BLOWING COOL AIR. THIS MAY ONLY SEEM LIKE A INCONVENIENCE, BUT HERE IN THE SOUTH SUMMERS ARE UNBEARABLE WITHOUT AC. OCCUPANTS OF VEHICLES COULD EASILY SUCCUMB TO HEAT EXHAUSTION. IT COULD BE DIFFICULT FOR THE DRIVER TO KEEP SWEAT OUT OF HIS OR HER EYES. THIS INCONVENIENCE COULD LEAD TO DISTRACTED/DISGRUNTLED DRIVING. THERE ARE ACTUALLY A NUMBER OF REASON THAT THIS COULD POSE A SERIOUS SAFETY RISK. GM IS WELL AWARE OF THIS ISSUE AND HAS FAILED TO PROPERLY ADDRESS THE SITUATION. I DIDN'T NOTICE THAT MY AC WASN'T WORKING UNTIL MY VEHICLE HAD 37,000 MILES ON IT. I'M POSITIVE THAT IT TOOK LONGER THAN THE FEW DAYS BETWEEN ME BEING AT 36,000 AND 37,000 MILES FOR THE REFRIGERANT TO COMPLETELY EXIT THE SYSTEM AND THE AIR TO NOT WORK. GM HAS OFFERED A HALF-HEARTED GOODWILL REPAIR THAT IS STILL JUST SHY OF $600.

AT 50,000 MILES, AND 24 MONTHS AFTER PURCHASING IT NEW, THE AIR CONDITIONING STOPPED WORKING DUE TO A FAULTY CONDENSER. AFTER INVESTIGATING THIS PROBLEM I FOUND OUT THAT THERE IS AN EXTREMELY HIGH FAILURE RATE OF GMC TRUCKS FOR THE SAME EXACT PROBLEM. IT IS A WELL KNOWN DEFECT PER SEVERAL GM DEALERS WHO ARE LEFT TO DEAL WITH THE PROBLEM. A BRACKET TO SECURE THE A/C LINE WAS NEVER INSTALLED WHEN VEHICLE WAS BUILT, CAUSING MOVEMENT IN THE LINE WHICH EVENTUALLY CAN RUIN THE CONDENSER, AC LINE AND COMPRESSOR. I ASKED GM DEALER TO FIX UNDER WARRANTY BUT WAS TOLD THAT THE BEST THAT GM WAS WILLING TO DO WAS TO PAY 40% OF THE REPAIR BILL. THIS IS UNACCEPTABLE, AS THE DEFECT IS WIDESPREAD IN MANY OF THEIR LIGHT TRUCKS

I TRIED SEVERAL GEARS, MULTIPLE TIMES, BEFORE BEING ABLE TO FINALLY GET THE MANUAL GEAR TO GET ME HOME.LOCAL DEALERSHIP CLEANED UP THE TRANSMISSION OF BROKEN METAL PARTS. 2,500 MILES LATER, I TRIED TO ACCELERATE AFTER TURNING INTO A LONG DRIVEWAY, AGAIN NO POWER. I TRIED SEVERAL GEARS AS BEFORE AND THE MANUAL GEAR GOT ME TO THE HOUSE.THE ENGINE WAS WORKING AND RPMS REVVED, AND JUST LIKE BEFORE, FELT LIKE IT WAS IN NEUTRAL. DEALERSHIP WENT ABOVE AND BEYOND TO TRY TO DUPLICATE THE PROBLEM. THEY EVEN CHECKED MY TRUCK FOR THE GM RECALL #14192, NHTSA CAMPAIGN ID # 14V374000, BECAUSE IT WAS HAVING THE SAME ISSUES. I THINK THAT THE BROKEN PARTS FOUND THE FIRST TIME WAS AN INCIDENTAL FINDING DUE TO THE FACT THAT THE PROBLEM HAS HAPPENED TWICE. DURING ALL THIS THERE HAS BEEN SMALL ELECTRICAL ISSUES IE: WEAK SOUNDING BUZZERS WHEN I OPEN THE DOOR, INTERNAL LIGHTS EITHER STAYING ON OR NOT COMING ON AT ALL, AND INTERMITTENT ISSUES WITH REMOTE START. MY HUSBAND BOUGHT THIS TRUCK BRAND NEW IN MARCH 2016, 6 WEEKS BEFORE HE DIED, SO THIS TRUCK HAS A LOT OF SENTIMENT, HOWEVER, I AM VERY CONCERNED THAT THIS TRUCK IS UNSAFE. THE FEAR OF BEING T-BONED IN AN INTERSECTION, OR SUDDENLY LOSING POWER IN 70MPH TRAFFIC IS TERRIFYING! I AM MOVING FROM SC TO WYOMING IN 6 WEEKS AND AM SCARED TO DEATH I AM GOING TO HAVE PROBLEMS. I HAVE REPORTED THIS TO THE GM COMPLAINT DEPT. SERVICE CASE # 83120854028. THE ONLY PAPERWORK I HAVE ARE THE SERVICE RECORDS FROM THE LOCAL GM DEALERSHIP.

I AM PAYING A NOTE ON THIS VEHICLE MONTHLY AND AM NOT ABLE TO USE IT. I CAN'T GET IT INSPECTED AND THE REGISTRATION IS OUT THEREFORE I CANNOT DRIVE IT.

THE GMC SIERRA HAS A TERRIBLE VIBRATION FROM 70 - 80 MPH. IT HAS BEEN IN THE SHOP 7 TIMES OVER THE LAST YEAR, 9 NEW TIRES, AND THE VIBRATION STILL CONTINUES. I HAVE ATTEMPTED TO RESOLVE THE ISSUE WITH GM BUT THERE HAS BEEN NO RESOLUTION. THE TRUCK FEELS UNSTABLE AND LIKE SOMETHING IS GOING TO BREAK ON THE HIGHWAY WHICH IS A SAFETY CONCERN. THIS VEHICLE HAS ISSUES AND IT NEEDS ADDRESSED.

BROUGHT IN MY 2015 GMC 1500 SIERRA TRUCK IN FOR VIBRATIONS ISSUES AT HIGH SPEED OF 70-75 MPH. AFTER 4 ATTEMPTS GMC CORP REFUSES TO ADMIT THAT THERE IS A SAFETY ISSUES IN DRIVING THIS VEHICLE AT A NORMAL RATE. THEY CONTINUE TO REMOVE AND REPLACE THE TIRES. I HAVE NEVER OWNED A VEHICLE BEFORE THAT SUCH VIBRATION IS FELT IN THE CABIN OF THE TRUCK, PASSENGER SEAT, FOOT PETAL, ETC.THAT IS SO UNCOMFORTABLE, THAT MY WIFE REFUSE TO DRIVE IN THE TRUCK DUE TO ITS SAFETY. GMC WILL NOT ACKNOWLEDGE ANY OF THESE COMPLAINTS BUT WILL SAY EVERYTHING IS OF SPECS. LIKE OTHERS THIS IS THE WORSE VEHICLE I HAVE EVER PURCHASED. FOUND MORE COMPLAINTS LIKE THIS HAS BEEN FILED, BUT SAME RESULT, GMC WILL DO NOTHING.
