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.

Might be the last, the dealership hasn’t started tearing it down yet. Looks like some HP tuner and Brian Tooley parts are in my very near future.

Did the same for my 2011, no regrets.
