Rating 5.0

I have a 2019 Forrester. 100k miles. Burns no oil somehow. I monitor it closely. I've changed the CVT fluid 2 times. Zero issues. I change my own oil every 5k miles. It's been so easy to own but maybe I'm lucky.

Pros: no oil burning, zero issues
Vehicle: Subaru Forester
Mileage: 100000 km

Seems high, but I’d be leery of going to independent shop for the cvt fluid. You really want to keep that as Subaru brand and the dealer will do the transmission relearn procedure.

Pros: dealer does relearn procedure
Cons: high price

The reality is that they need more thoughtful and consistent maintenance than other cars, and the maintenance tends to cost a bit more.

As long as you pony up the effort and money to maintain them, they are very reliable.

And I'll repeat, again, as I have so many times: Change your CVT fluid every 30k miles.

Pros: very reliable with maintenance
Cons: higher maintenance cost

Also consider doing cvt fluid changes every 30k or so despite dealers considering it a “lifetime sealed unit”. So far mine hasn’t had the slightest hiccup over its 50k miles. They’re relatively simple and easy to service if you’re even slightly hands on as well. I certainly expect to get more than 10 years out of mine

Pros: no hiccups, easy to service

Same question for Europe: Subaru in Germany recommends cvt fluid change every 45 000km on heavy duty and every 90 000 on standard usage.

At what point would you recommend to change CVT fluid in a 2018 Forester? A relative has one with 45k miles and it developed a quiet “howling” noise starting at around 50mph. It is not very loud and we cannot the if it’s coming from the CVT. It doesn’t go away when transmission is shifted into Neutral at that speed. Front and rear differential fluid has been replaced.

Cons: howling noise at 50mph
