2019 GMC YUKON Complaints

it's been a known fact and on social media there has been many complaints, why is there nothing being done. this vehichle has a water or moisture problem which goes to the electric connectors and makes the vehichle go in to derate mode and only code it throws is peddle position sensor. which I have changes, and still no fix, as other connectors that are going to the electronic board removed, and it has corrosion. this is clearly a safety risk and it literally puts in a mode where a truck is not drivable.

-Automatic transmission failed. Slipped, skipped, and bucked while driving. -Taking a left turn into traffic transmission hesitated and just started slipping almost causing an accident. -Dealer confirmed torque converter failed and transmission needed replacement. -No warnings. No towing. Just 89,000 highway miles commuting to work. No heavy loads or abuse. -Had to replace the transmission, not covered under warranty due to mileage. Not available for inspection.

This car had catastrophic engine failure due to the lifters, push rods and camshaft. This car make and model and engine type is notorious for these specific parts to malfunction. This could have left myself and my children stranded on the interstate. The vehicle has been inspected by a certified master technician with ASE training. They confirmed that these parts are a common issue with these cars.

Engine Lifters failing and vehicle making a squeaking type noise. Check engine light came on briefly 2 weeks ago and went off. Problem confirmed by GMC dealer whom also reports they have multiple vehicles at shop right now with lifters and cam shaft problems

The contact owns a 2019 GMC Yukon XL. The contact stated while driving at an undisclosed speed, he heard an abnormal sound coming from underneath the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a general failure with the transmission. The vehicle was repaired, but the failure recurred. The vehicle was taken back to the dealer, who again diagnosed a general failure with the transmission, and informed the contact that the transmission needed to be replaced. The vehicle was repaired; however, the failure recurred. The manufacturer was not notified of the failure. The failure mileage was 65,000.

Service Trailer Brake System keeps coming on while driving. Dealership says nothing wrong although they replaced fuse. Still happening. Only thing that seems to work is pulling off road and restarting vehicle. That is only a,temporary "fix". Comes back a few days later. This is a safety issue as 1) distracts me while driving 2) I pull an 8,000lb travel trailer with the vehicle.

The contact owns a 2019 GMC Yukon. The contact stated that the third-row seats electrically controlled failed to function as needed. The contact stated that that the seats failed to move forward or backwards. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the third-row seat unit needed to be replaced. The vehicle had not been repaired.

I actually own two GMC's one is a 2018 GMC sierra and this vehicle and they both have transmission problems. This vehicle has 100,000 miles on it and the transmission is gone, you want to charge 70,0000.00 for a vehicle that has a sup par transmission and to replace it cost over 6000.00. The sad thing is when I pulled up to the dealership and told the sales manager and shop manager my problem they just shook their head and said it won't be good and that they have had to replace a lot of them, so many that they keep the transmission in stock like wiper blades. This is utterly ridiculous and I have bought and paid for at least six or seven GM products in my life but this will be my last one I promise you that.

Transmission failed while driving down the road. Trasmission reved up while driving and would not go faster then the car started slowing down. Thank goodness this was not on an interstate or it could have caused an accident. Check engine light came on as I was getting to the shoulder of the road.
