I spent 2017 and 2018 running a shop that all but specialized in Subarus. That’s because they’re the only popular cars that still require regular engine work. That “Subaru Cooling Conditioner” they put in every new car they sell is also sold as, “Holt’s RadWeld.” They are such horrendous engines that stop leak is standard equipment. A good rule of thumb is never put stop-leak in something you plan on owning for more than a month.
A friend’s son has a 2018 WRX that needed an ECU and VVT control solenoids at 11,000 miles. When it turned out that the dealer had failed to talk my friend into the ‘high performance reflash’ that Subaru uses to void its warranties on their turbocharged offerings, Subaru then went on to try and find some non-existent evidence of missed maintenance on an 11,000 mile old car to deny warranty repair on an ECU. He won’t make the same mistake next time.
I have zero tolerance for people telling others that a Subaru is a reasonable purchase. Right now I’m dealing with head-gasket failure on an ex-gf’s Outback. She told me that the dealer said it was a freak occurrence, that they never fail. I told her the truth at which point she finally looked at the internet and saw the trail of the best-selling head-gaskets in the world.
We worked on plenty of Subarus that had 200,000 miles or more. They are a counter-culture status symbol, and the people who weren’t crossing their fingers while driving with deferred reseal jobs at 100,000 mile intervals were spending more money in upkeep than it would have cost them to lease a new RAV4. I could write a book about the things Subarus does worse than anyone else where head-gaskets are just a chapter.
