Regarding a catastrophic engine failure involving my 2023 Chevrolet Suburban equipped with the 6.2L L87 engine. There is an active GM service bulletin that we never received from either Crabtree or GM. Vehicle details: • Purchased in North Carolina in 2024 • Approximately 4,000 miles at purchase (used, still under factory warranty) • Currently at approximately 60,000 miles • Within the 5yr/60k powertrain warranty at the time of failure Incident details: On Friday 2/20, the engine experienced a confirmed catastrophic failure while my wife was driving on the interstate at highway speed. The vehicle abruptly lost power, creating a significant safety hazard. She was able to maneuver to safety, but the situation presented a serious risk of injury. GM has since towed the vehicle and confirmed catastrophic engine failure. We have been provided a rental vehicle - not a comparable one either (they refuse to address that also). Given the safety exposure and warranty status, I am evaluating p...

Seat Belts

The drivers side, female end, of the seatbelt comes undone when cold. This is reproduced every single time it is cold for approximately 5 minutes of driving until the inside of the vehicle warms up. This happens with both primary divers of the vehicle. We took it to the dealership we bought it from but because there is not a current recall and they cannot reproduce the issue since our current temperature is in the 40s, they won’t replace it under warranty. No warning systems go on when this happens while driving.

Sun Roof has leaked. The Sun roof leaked a considerable amount of water and it came through the head liner around the ceiling mounted control panel as well as the back of the car. This is the second time it has happened and I have been told it is not covered under warranty. Through online blogs and forums I have found that this is a common issue with 2021 and newer tahoes and suburbans. And that is a reoccurring problem that is commonly not fixed properly by the dealers This causes a safety and health issue as well as an unacceptable vehicle defect. 1.) From a safety standpoint, if I am driving down the highway and a large amount of water starts pouring out of the headliner on the driver it causes a major distraction that could lead to high speed accident. 2.) From a health issue, regular water leaks could lead to vehicle mold and water damage. I have children, if they become susceptible to the mold it could cause health issues for me or my children. 3.) The water that pours out of...
