I know Subarus probably aren't the most popular choice among TexAgs auto board posters, but for anyone driving a 2020-22 Outback or Legacy, a 2019-21 Forester, or a 2021 Crosstrek be aware of the ticking time bomb that is the electronically-controlled "thermo control valve". Instead of a tried and true spring loaded thermostat, these models have a crappy plastic electronically controlled valve that is failing at a very high rate, so Subaru extended the warranty to 15 years or 150,000 miles. I think models up to 2024 still have an electronic TCV, but it's a "new and improved" design that I don't think is automatically covered by the extended warranty. I'm sure this TCV improved emissions and fuel economy by 0.0001 percent, so I'm glad my wife's Forester has this feature (which just failed yesterday).
