“Engine failure while driving 75 miles per hour in highway in brand new Yukon Denali. 3,000 miles and got a “decreased acceleration” warning. Then couldn’t accelerate and loud knocking noise from the engine, likely a lifter issue. I will have to get a new engine according to GMC. Unbelievable. Recall was for 2021-2024, but my 2026 is havin the same issue.”
NHTSA complaint #11716485, filed 2026-02“My engine with less than 5,000 miles died (engine was blown). While driving on highway engine died and wheels locked and almost caused a major accident. I had to get a tow and bill cost me 700.00. GMC is giving me the run around. Dealer stated that engine will need to be replaced. GMC is doing nothing to assist me, I have a car note with no truck GMC is the biggest scam.”
NHTSA complaint #11740744, filed 2026-05“GMC should be haulted from selling trucks with the 6.2L engine. My brand new 2026 GMC Yukon Denali engine imploded on the Interstate going 75mph that nearly killed my entire family. No warning, just out of no where died on the highway, with 4K miles on it. This is sadly going to get someone critically injured and when is enough going to be enough? GMC has some explaining to do, when they charge $85K-$100K for trucks that blow up as soon as you buy them.”

NHTSA complaint #11755813, filed 2026-08“Nothing has happened yet. However, after only 308 miles… my 2026 Denali is knocking and ticking very loud. Why? How is this possible? We’ve only had it 2 weeks! I have only driven it 5-6 times in the past 14-15 days, too worried that this might happen. But I was reassured by the dealership it wouldn’t. But here I am now. I am so disappointed. Being a Disabled Vet I thought we could have something that we both liked. Now I am upset because I feel betrayed and lied to. I did a video but it’s too large to upload so I can’t get it under 10MB.”
