Dealership recommending HV battery fan service for Prime

IMHO: You shouldn't need to clean the fan, if the filter is in place and undamaged. That's the job of a filter!! Now if the filter is missing or damaged, you'll have to clean out the entire pathway - just to be safe and ensure everything is working properly. Whatever damaged your filter, could be hung-up in your air cooling system someplace - ready to short-out or damage something else.

DEALER RECOMMENDED SERVICE vs. FACTORY RECOMMENDED SERVICE

Dealers ALWAYS recommend addition services. I took my 2021 Prime to a dealer for the first time since I purchased the car. With 50k, I purchased the factory recommended 50k service. Additionally the Service Department wanted to empty, flush and refill my fuel tank for $350 and replace my PVC valve for another $250. Of course they also wanted to empty, flush and refill my brake fluid. NONE of these items is factory recommended. Just profit for the service department.

By the way, after changing my oil and rotating my tires, they didn't even top off my fluids. After checking, I had to go back and make them do that. Poor service but about what I expected. I did get their free 20 point inspection report.

This has been my experience at most authorized dealers, Toyota, Honda, BMW, Subaru, etc. Doesn't matter where.

 

That's crazy!!

Probably not needed, but not that hard of a job as I recall.

Not necessarily a bad thing to do at 50k. There is a simple test for moisture, though.
