Yea... that damned DOD stuff is rather.. annoying. I had a Saab that I bought with a failed DOD. Luckily it had not done any carnage. So I pulled the head, replaced the lifter and pushrod.. And turned off the DOD system. That lasted about a year, and then the head gasket on the other side blew. I got rid of it at that point.
My Envoy has 375k (estimated, replaced odometer) miles on it, engine has never been opened to date, and she still purrs right along getting 17mpg.
I want a Denali/Esky.. But those damn engines. And in the modern trucks, I would get a diesel.. But now the interior is junk,
I cant win with GM at this point. I got a order in for a Rivian... But I am still looking at other trucks. Toyota Sequoia, Dodge Durango RT, Jeep Grand Cherokee SRT.
I know right? Once I passed her the keys, we reviewed the scan pattern of the instrument panel.. Oil pressure, coolant temps, trans temp.. No noises? Check? Clear right? OK.. Full throttle.. Same as she would when she's flying jets.. lol
Dont you know... Wives cant drive your daily driver.. Not if you want to have any sanity..
I remember years ago, I was on a business trip for 4 weeks. She used my car while I was away. Came back to the top of the engine clattering.
Asked the wife about it, "oh yea, I meant to tell you that the red light kept coming on". But she kept driving it. Oil pressure o-ring had failed. It had 1/2 quart of oil in it.
