Kaboom! My 6.2 self destructed yesterday.

2023 Yukon Denali 20,549 miles. Just picked it up Tuesday from another unrelated repair and routine oil change.

I was driving with my wife and 7-year-old son in the car when the engine completely failed without warning.

No check engine light. No prior symptoms. Just instant power loss and the transmission throwing itself into neutral while I was in the middle of highway traffic. I had to fight my way across multiple lanes to reach the shoulder—without power, hoping I wouldn’t get rear-ended.

Additionally, my vehicle has had seven prior repair visits since July 2024 for persistent electrical and camera system failures due to water infiltration and wiring harness corrosion.

Worst vehicle I have ever owned.
