GMC Complaints

This is the 3rd Yukon I have owned all 2001-2003. Every one of them have had serious brake issues, ABS illuminated, Parking Brake does not work, and light is illuminated, brake fluid everywhere, which when hot starts eating away at electrical components, or in my case at cooling system hoses. Which all lead too one issue after another. I really think that this shoudl be address becasue eveyone i speak with has the same issue. It's exhausting anf expensive too fix, but i have no choice becausei need 3 rows too fit all my children and cannot afford a brand new car.

Purchased the vehicle 300 miles away. Flew out, picked up the truck and drove it home. Got back Saturday night. Woke up Sunday morning to review the features, etc. Noticed a major oil leak. Called the dealership I purchased it from. They told me to take it to a (local) dealership. I took it to my local dealership. They looked at the vehicle. Initially they thought it was a faulty valve cover gasket. They ordered the parts. When they actually started taking the vehicle apart, the issue was not the valve gasket but the crack in the valve cover itself. They replaced the valve cover. It went to the dealer on date 03/03/2025 and they gave he vehicle back to me on 03/21/2025. They said this crack had to of happened on the production line but before it got delivered to the initial dealership.

I was 30 seconds away to pull in my driveway. WARNING came up on screen (service) TRANSMISSION UNABLE TO SHIFT. When I turned into my driveway the vehicle stopped suddenly & threw itself into PARK. Vehicle still running but would not go into any gear, drive or reverse. I then pushed the PARK button & I think it said EMERGENCY BRAKE RELEASED. I then proceeded to drive up my driveway with no problem. Haven’t gotten back in vehicle yet as I am afraid to but l made appointment to take it to the dealership to check it out. On 3/24. (Linus Cadillac Buick GMC)Thank god it happened in my driveway as it would’ve caused an accident. ( the vehicle was driven up the Rd. walking distance. Sat there for an hr. Visiting my family. Then was driving home When incident happened. So it wasn’t running hot or anything.

Shift to park message appears when in park and engine is turned off. Transmission control had an internal circuit failure. Park not fully engaged and vehicle could roll. Problem confirmed by dealership. Prior recalls for earlier gmc models but not my year.

Was driving down the main highway in town when the truck suddenly shut off. No lights, no warning. Had the truck towed to the dealership and called my insurance company as I had recently had the fenders and hood repaired after having a fender bender in my front yard. The insurance company looked at the truck and inspected the motor and told me the motor had locked up. They said this was a common issue with the motor for my truck and they wrote a report about it. I emailed the CEO of GMC and requested help since my truck was just over the mileage that warranty would cover. Her assistant contacted me and agreed to check out the vehicle, investigate and determine a cause and see if they can supply assistance. After 6 months of investigating, they determined the crankshaft broke, but also told me the valves was a major contributor to that cause. They offered to discount the cost of a replacement motor. I declined, so they discounted it further. I declined again and they offered me one final offer of $7500 before tax for a motor and install. I had a quote from another local company for $6000 and told them no again. Her assistant said they could no further help me. I have the documents from my insurance when they investigated and I have the emails I sent but only 1 response from them. The rest of the communications was over the phone. It’s been a year and half and I still don’t have a running truck, but I have a 800 a month truck payment that I have to pay.

The contact owns a 2013 GMC Acadia. The contact stated that intermittently, the vehicle was difficult to start. Additionally, the contact stated that while driving at various speeds, the vehicle stalled. The check engine warning light and the traction control warning light were illuminated. The vehicle was taken to an independent mechanic, where the alternator, the stabilizer, starter, ignition switch, the door panel, the axle, the matt sensor, the canister valve, gas cap, and power master window switch was replaced; however, the failure persisted. The mechanic determined that the failure was related to the fuse box. The contact used a diagnostic scanner to scan the vehicle but was unable to retrieve any diagnostic trouble codes. The dealer was notified of the failure and informed the contact that the VIN was not included in a recall related to the electrical system. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 92,000.

Replaced the exhaust tail pipe tip past the DPF and warning light came on after miles of driving. Vehicle was locked up and only able to drive 55 Mph and there was a countdown to it dropping even lower. Dangerous to limit speed. This shouldn’t happen anyway with just changing out exhaust tailpipe. Very costly unnecessary repair

My motor seized and shut off while driving 63 mph on a busy highway going up hill. Truck made it to the top of the hill before it shut off and had to coast to a stop on the side of the road. No warning lights or anything. Rpms locked at 3000 and wouldn’t go up or down until the motor shut off. Switched itself to neutral while it was rolling still and wouldn’t allow my to put the truck in park when stopped. Finally locked itself in park and wouldn’t allow to be shifted to neutral. Dealership said the motor seized and ordered a new one but is on back order

The contact owns a 2019 GMC Sierra 1500. The contact stated while driving at approximately 20 MPH and making a left turn, the vehicle shook violently. The contact stated that no warning light was illuminated. The contact stopped the vehicle and turned off, and restarted the vehicle. The vehicle was restarted, but after shifting into drive(D), and depressing the accelerator pedal, the vehicle failed to exceed 30 MPH. The contact stated that the vehicle was making an abnormal "roaring" sound. The contact stopped the vehicle and had the vehicle to be towed to the dealer. The dealer diagnosed the vehicle and determined that the valve body on the transmission needed to be replaced; however, the part to complete the repair was on a national back order. The vehicle was not repaired. The manufacturer was informed of the failure. The contact stated that the failure was the second transmission failure. The contact had the transmission replaced in 2024 by the same dealer. The failure mileage was approximately 84,000.
