Just had my rear main seal replaced under warranty at 83,000 miles. Has anyone else had theirs go out this soon?

Nobody?...That's not a good sign...

So when have you seen them go out?

At the dealership, I saw them go out at <20k miles. Not unheard of by any means.

  I'll bet your truck lost the bearings on a roller on 1 of the lifters, and now is wiping out a cam lobe.

  2024 2500 gasser with 47,000 miles. Driving on interstate Friday when my truck shudders, downshifts, and I get the above message with check engine light. Transmission would not upshift. I had to drive home 2 hours at 65 mph at 3600 RPM with transmission temps 190-200 degrees. Got it to the dealer Monday. They ran the code and said the #1 valve body was malfunctioning in the transmission. Miraculously, they had the part in stock and I had a new valve body installed that day with new transmission fluid/filter. Thankfully, all under warranty. Shout out to Everett Chevrolet in Hickory, NC.

  My truck rarely sees a dusty, dirt road, if ever. Actually, never. Within 6mo of ownership, mine was totally covered with road dust and yellow, Louisiana pine pollen. I swear, it looks 6yrs old. You'd think it was an oilfield, or pipeline service truck. Did GM just do a piss poor job of sealing the bay? Anyone else with this issue?

  Ha!! So GM Customer service, ive already been talking with someone on your email team and there is nothing they can do. So pretty consistent with everyone else’s experience- you can do NOTHING.. worthless emails. Sure glad i have 4 GM cars on our family cuz now its clear you dont care.. Sad and pathetic.
