GMC Complaints

I was driving and my vehicle started to give me warnings to pull over due to low oil. When I safely pulled over and check. the engine oil cooling line was detached from crimp joint and leaked all the oil. Called the tow truck and took the truck to the dealer (Charles hardy chevrolet in Dallas GA) And they telling me that the engine is locked and it need to be replaced. There is a recall for the part but they telling me that my vin number is not part of it. Even though is exactly what the recall said it would happen

I was driving in a parking structure at low speed when a loud bang went off inside the cab. The hazard lights went off, there was an acrid electrical smell, and fine dust was coming from the steering wheel area. I stopped the truck and got out to look for a collision, but there was none. When I restarted the truck, the air bag light came on and I noticed that the seatbelts were retracted and no longer functional. I was not injured, but I believe that if this had happened in traffic or on the highway, I and my passenger could have been seriously hurt. The vehicle was towed to the GMC dealership, where they identified an error with the module that sends a signal to the airbags and seatbelts to deploy. Prior to this occurrence, I had no indication that the airbag/seatbelt system was faulty or in need of service.

UNKNOWN - While driving down the highway, the front hood molding flew off the front of my truck after a semi passed by me going the opposite direction. No physical contact was made to any part of my vehicle had occurred. The molding piece flew directly behind me on the highway and almost hit another car. I pulled over and inspected the front and noticed that the plastic clips that hold the molding piece in place had snapped off. After researching online, I have found numerous instances of people reporting the same thing happening to them.

The engine in my 2020 GMC Terrain is consuming oil at an alarming rate, burning through a full supply within one hour of operation. This excessive oil consumption has repeatedly caused significant damage to the coils and spark plugs, rendering them ineffective within 24 hours. The issue has led to multiple cylinder misfires, poor vehicle performance, and a transmission stall, posing a serious safety risk while driving. The GMC mechanic at Jim Ellis Buick GMC diagnosed the problem as internal damage to the pistons, which they state requires a full engine replacement. They also confirmed an internal oil leak within the engine, which is contributing to bad emissions and further degrading vehicle performance. This defect not only compromises the reliability and safety of the vehicle but also raises significant environmental concerns due to the excessive oil burning and emissions. I am requesting a thorough investigation to address this issue and determine whether it is part of a broader manufacturing defect affecting similar vehicles.

CAR IS LOSING OIL, NO DRIP ON GROUND, MUST BE BURNING IN MOTOR, HAVING TO ADD OIL EVERY FEW MONTH. THIS IS BEING GOING OWN FOR ABOUT 3YRS. WHEN WE GET OIL CHANGED, HAVE TO ADD OIL WITHIN 3 OR 4 MONTHS. HAVE STOPPED DRIVING CAR. NEED TO SALE IT NEED TO GET CAR FIXED. LOSING OIL WHEN DRIVING. NOT WHILE PARKED.

BRAKE FAILURE ISSUE AT LOW SPEED. THIS HAPPENED IN TWO SEPARATE OCCURRENCES IN PARKING LOTS. THE BRAKE PEDAL BECAME VERY STILL AND REQUIRED GRABBING THE STEERING WHEEL AND USING IT TO PULL MYSELF DOWN HARDER ON THE BRAKE PEDAL TO GET THE VEHICLE TO STOP. THIS RESULTED IN GREATLY INCREASED STOPPING DISTANCE. FORTUNATELY NO VEHICLES OR PEOPLE WERE IN MY PATH DURING THESE OCCURRENCES. GM HAS SINCE REPAIRED MY VEHICLE. I HAVE SINCE RECEIVED A NOTICE THAT THEY ARE REPAIRING THIS ISSUE ONLY AFTER THE OWNER HAS A BRAKE FAILURE PROBLEM. THIS IS EXTREMELY UNSAFE AND IS UNACCEPTABLE. OWNERS NEED A SOLUTION AND DO NOT NEED TO WORRY THAT THIS ISSUE WILL ARISE AGAIN. IF I HIT A PERSON OR A VEHICLE, WILL GM PAY FOR MEDICAL BILLS, VEHICLE REPAIRS, LEGAL FEES? THIS TRUCK AS WELL AS MY LAST 2009 CHEVROLET SILVERADO HAD ISSUES WITH THE DRIVE TRAIN THAT GM CLASSIFIED AS NORMAL. THESE TRUCKS SHOULD NOT HAVE DRIVE SHAFT CLUNK WHEN STOPPING AT A TRAFFIC LIGHT. THESE VEHICLES HAVE MAJOR MECHANICAL CONCERNS AND THEIR QUALITY IS TRASH!

PASSENGER BREAK LIGHT INTERMITTENTLY WORKS. TOOK TO GMC THEY SAID THERE IS NO KNOWN ISSUE WHICH IS A LIE! HUNDREDS OF OWNERS ONLINE HAVING THE SAME ISSUES. THEY SAID THEY CAN'T NAIL DOWN THE ISSUE SINCE THERE'S CLEARLY POWER THERE. THEY WANT ME TO BUY A WHILE TAIL LIGHT ASSEMBLY! ABOUT 900 DOLLARS FOR THE SAME FAULTY PART!

A/C REFRIGERANT LEAKS OUT AND BURNS EYES WHILE DRIVING. AFTER A FEW TIMES OF USING AND EYES BURNING, ALL REFRIGERANT LEAKS OUT, LEAVING A/C NONWORKING IN VEHICLE

BOTH TAIL LIGHTS WORK INTERMITTENTLY. I HAVE BEEN STOPPED BY OTHER DRIVERS ON SEVERAL OCCASIONS TO TELL ME THAT ONE OF MY TAIL LIGHTS WAS NOT WORKING. BOTH LIGHTS ARE EFFECTED, BUT NOT USUALLY AT THE SAME TIME, SO I AT LEAST HAVE ONE WORKING LIGHT AT A TIME. THIS HAS BEEN HAPPENING SINCE I PURCHASED THE VEHICLE FROM THE DEALERSHIP USED CAR LOT ON 01/23/2019 WHETHER I AM SITTING STILL OR DRIVING DOWN THE ROAD. WHEN THE LIGHT GOES OFF, YOU CAN HIT THE LIGHT ASSEMBLY WITH YOUR HAND AND IT WILL MOMENTARILY COME BACK ON.

MY CAR IS BARELY 3 YEARS OLD AND HAS ONLY 24,000 MILES ON IT BECAUSE I WORK FROM HOME. I SPECIFICALLY LEASE CARS SO I DON'T HAVE TO DEAL WITH ISSUES. THIS CARS REAR PASSENGER BRAKE LIGHT NO LONGER WORKS! THE SERVICE MANAGER AT THE GMC DEALERSHIP SAYS THEY HAVE TO REPLACE A GREAT DEAL OF THESE IN CARS NOT VERY OLD LIKE MINE. THIS IS DEFINITELY A SAFETY ISSUE FOR BRAKE LIGHTS TO BE GOING OUT ON A 3 YEAR OLD CAR! IT HAS BEEN OUT FOR MONTHS AND I WAS JUST PROCRASTINATING BECAUSE YOU MUST GO TO A DEALERSHIP SHOP TO GET IT REPLACED. YOU CANNOT GET IT AT A PART STORE YOURSELF SO MY CAR PROBABLY ONLY HAD 20,000-21,000 MILES ON IT WHEN THIS STARTED.
