Anyone else having engine problems on their turbos?

I had 2 engines blow this week one on a 2021 Gen 4 expert turbo with ~3,000 miles (PTO rod) and the other a 2023 Gen 5 expert turbo with only ~300 miles (waiting on full diagnosis). Hard to stick with ski doo but I suppose all brands have engine problems. Looks like this season might be over before it even got started.

...what oil are you running? Are both stock?

Polaris rider just trolling
Not trolling, I have a Gen 4, Gen 5, boost, and 9R. Just thought it was wild the both blew within a day of each other and wondered if others had problems. No issues on the Polaris so far but that said I only have 1k miles on them so who knows. My lesson was always get new sleds before the warranty expires.

Cheers

Unfortunately for the customer, engines are produced to last to the end if warranty and that’s it. Then you need to buy a new engine from the manufacturer. Ya ya, your buddy’s sisters dad’s lasted for 10k miles. Dad has never been wfo. Haha

Are you running aftermarket tunes and a can on them?

Over this passed weekend my Gen 5 expert turbo started running on one cylinder and eventually stopped running altogether, thankfully got to the trail on one cylinder before it broke down. Brought in to dealer and got a long list of issues. My sled only has 791kms on it. Pistons and reeds only expected to arrive in December so there goes the rest of this season and a chunk of next season, quite a disappointment. Here's the dealer report:

You should push for a new engine since they stated the oil pump isn't working properly which is supposed to lube the crank as well.
