What owners report
While stopped in a parking lot. I returned my vehicle to drive home, and the car would not start. I had it towed to the dealer. They did a diagnostic inspection for "crank-no-start ". Two trouble codes: P0340 intake single camshaft ignition sensor circuit and P00C6- fuel rail pressure load during engine cranking. Performed diagnostic checks and suspect a broken timing chain and timing tensioner that causes the bottom of the engine to free spin while the top 0.5 does not. These engines are known as interference engines, and anytime there is a mismatch between the top 0.5 and the bottom 0.5, there is the potential for catastrophic failure due to the design of the valve train and bottom 0.5 of
As I was driving down the road at 60mph, no dash lights or warnings were present. All of a sudden, my 2021 yukon lost all power and I nearly crashed as I was in heavy, fast paced traffic.

crank/rod failure on 6.2 engine. yes it is available same as other people with blown 6.2s yes, GMC dealer diagnosed crank failure no no. engine still runs but is knocking and squealing but dies after a few mins and won't restart till it cools off
Our 2021 GMC Yukon Denali has repeatedly experienced sudden, violent braking and apparent rear-wheel lockup without the driver applying the brakes. These incidents occur without warning at highway speeds, moderate speeds, and in traffic. The vehicle abruptly decelerates, fishtails, loses stability, and produces smoke. The wheels have locked severely enough to leave skid marks on the roadway. This creates an immediate risk of losing control or being struck by another vehicle. We took the Yukon to Alpine Buick GMC on October 12, 2026. After eight days, the dealership reported that it could not reproduce the malfunction. However, its written findings confirm that an engineering case was opened
