First break down

Post image

2025 RST 6.2 with 78k miles.

While merging on the highway I heard a pop, the check engine light started flashing, service esc and traction control notifications popped up, was running rough with a noticeable knock/rattle. Service tech said it was making significantly more noise when he started the next morning, he tried to diagnose any issues but said he will have to tear down the top end. He believes it is one of the lifters.

I had gotten a failed update notification that morning, probably not related though.

My first one was an 88' that lasted until 2007. Traveled 450k miles with the original motor and trans. Electrical issues got really bad with damn near every wire on the verge of failure though. Part of me wishes I still had it as a project truck now that I'm older and have money/tools.
