INVOLVED IN A FRONT/SIDE PASSENGER SIDE COLLISION WITH SIGNIFICANT DAMAGE AND SPEED WITH NO AIRBAG DEPLOYMENT(S).
I WAS DRIVING MY VEHICLE AND EXITING THE HW. THE REAR WHEEL OF THE DRIVER SIDE BROKE OFF AND SEPARATED FROM THE CAR WHICH CAUSED MY CAR TO HIT THE CEMENT BEERIER ON FRONT AND THE SIDE OF THE DRIVER SIDE OF THE VEHICLE. THEN THE CAR TURNED 180 DEGREES AND HIT THE BEERIER ON THE PASSENGER SIDE AND THE REAR OF THE CAR. THE AIR BAGS NEVER DEPLOYED AND WE DISCOVERED THAT THE WHEEL BROOK OFF OF THE REAR AXE. NO DAMAGE TO THE WHEEL. SEVERAL INDUSTRY EXPORTS STATED THAT THIS SHOULD NEVER HAPPEN.
I started my vehicle and as I accelerated I started to hear a knocking noise. The vehicle and engine have been inspected by the dealership. The problem has also been confirmed by the dealership.There were no warning lights or messages before the knocking noise started.
The 2018 Yukon has been at the dealership several timeswaiting for a valve body for the transmission. There are valve body recalls for other year GM vehicles with the same transmission, but not for the 2018 model even though it appears to be the same part number. I don’t understand how this 2018 model apart of the recalls when it’s got the same issues as the newer ones. This is the second Yukon I’ve bought in the last seven years and the other one had the exact same issue.
The contact owns a 2018 GMC Yukon. The contact stated that the vehicle was taken to a local dealer for service, and the contact was informed that the radiator was leaking and needed to be replaced. The contact stated that there were no signs of a leak prior to taking the vehicle for service. The contact was advised by the dealer that it was a common failure for the year and model vehicle. The manufacturer was contacted and offered a buyback. The vehicle was not repaired. The failure mileage was 128,640.
I purchased my used GMC YUKON from a used car dealership 3/28/26. I signed the papers for the agreement while I was driving the vechicle home I lost power and it wouldn't go forward with gas applied. The check engine light came on, I pulled the suv over and it was towed. The code that popped up 0700 and 02723 both codes having to do with the transmission.
The 2018 Yukon Denali has been at the dealership for 7 weeks waiting for a valve body for the transmission. There are valve body recalls for other year GM vehicles with the same transmission, but not for the 2018 model even though it appears to be the same part number. The transmission was already replaced on this vehicle at 500 miles.
As of [XXX] , I witnessed a squealing sound coming from the rear end of my 2018 Denali Yukon XL truck. And it's affecting my braking. And it jerked when I changed my gears on my truck . And there are lights on in my dashboard on my truck. The engine light was blinking on and off and the traction control light was blinking on and off also. But the back driver side of the truck was squealing also. Please help me to resolve this situation. In the name of Jesus. Thanks again [XXX] and [XXX] .

The vehicle was towed to the dealer where it was diagnosed and determined that the transmission needed to be replaced, and that the engine block was damaged. The transmission and engine block were replaced, and the vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was 104,000.

Dealership did a tune-up in June 2025 and had my truck for 2 weeks, no issues with transmission discovered or discussed. Now in September 2025, 2018 GMC Yukon has developed a torque converter shutter when driving between 40 and 50 mph. I took the vehicle to an independent shop who told me they had some computer tool to manually control the transmission, and there is an internal failure. There was a transmission flush completed hoping to gain results, however it was very short lived.
I was driving on I75 North, just North of Chattanooga. I was in the Center Lane. I lost all power to the vehicle. The engine stopped. I had no power steering, no power brakes, and was in heavy traffic. I managed to shift lanes and get it to the shoulder of the road. The vehicle was towed in. Diaganostics were completed by a certified mechanic. The engine had seized. GM has several recalls on this issue. 2018 is not included. However, this is the exact same issue that is happening with 2019 and up. That were recalled. I urge you to order an extended recall to include 2018 vehicles as well before someone gets killed.
My 2018 GMC Yukon blew an engine with only 81,000 miles. Had four shops including (2 GM dealerships) look at the vehicle, pictures, and findings and concluded the engine had blown. The vehicle had began running very rough while driving down the road at 45mph. The CEL showed a misfire in cylinder one. The spark plug was pulled and soaked in oil. A borescope was put down the hole and found oil pooled on top of the piston. The engine has blow by the piston rings and the cylinder wall was scorn. Four shops. Four results. New engine needed. A quick google search of the engine (L83) showed multiple open class action lawsuits for this exact situation. The cause of the problem is the active fuel management system that GM created. When I contacted GM for assistance at the recommendation of the dealerships (which they have seen an increase in these engine blowing with low miles) I was informed by GM/GMC that they would look into it and could not guarantee assistance. Fast forward a couple of days I was contacted and made perfectly aware that I was 991 days outside and 21,000 miles out of warranty but they would offer “assistance” in the amount of 10% of the total cost. Four shops, four quotes for an engine replacement ranging from $14,750-$17,000 and GM was only offering $1,475-$1,700. Absolutely terrible. With multiple open class action lawsuits, stop sales, and well documented issues. I expressed disappointment and requested assistance to prevent having to seek litigation. I was told “if that’s what you want to do, you will need to talk to our legal department” and told there’s nothing they can do. Will not buy nor recommend anyone buy a GM product. They don’t respect or care for their customers.
