2021 diesel Tahoe engine turn off when driving
Misrouted harness and subsequent wear. Look it up in recalls. In particular look near the alternator bracket. Do you ever get weird dashboard messages regarding brakes and cruise control and collision avoidance system? Should get some codes, but if the ECM has a power interruption, maybe not.- dbphillips

2024 Yukon Denali Diesel impressions
This. I got an RST and quite satisfied, in spite of some out of service issues, bad camber geometry in the IRS and an oil leak that should be fixed (crosses fingers, touches wood). If I had paid $20k more, I'd be pissed! And our transmission kind of hunts unloaded, but rock solid when towing. Odd.- dbphillips

Thoughts on purchasing a higher-mileage Duramax?
If it's a 3.0L and it wasn't a case of the owner dying and no one in the family wanting it, I wouldn't go near it. I was willing to let GM buy mine back as a lemon due to time out of service (turns out it didn't qualify), but the only way I'd sell it is if it had a known issue, even though I...- dbphillips
