3 years of ownersip of my 2020 Gen5 OB and 32,000 miles on the clock. My first Subaru ever, after years of considering them, but opting for a string of Skodas (4x4 1.8T Octavia, x2 Yetis (4x4s) and my partner is on her 4th Fabia). I was commuting them and Subarus have always been relatively thirsty, but that's not an issue for me know as I work from home mainly. All the Skodas were great and serviced for over 20 yrs by a local independent Skoda specialist - never any issues.
So the Gen5!! Firstly, I love alot about the car. It's size; it's off-road ability (which is why I bought it); etc. But (and it's a big but) I've used Subaru dealers for the last 3 services and the experience has been dreadful. Apparently, major problems with the NSF brakes wearing out - needing new discs and pads ( in 7,000 miles, and then after 10,000) and despite my arguing with the last two dealers that this is a mechanical problem, with that individual caliper, and not normal symmetrical wear-and-tear, and so a warranty issue, they can't/won't agree. So I've been 'banging my head against a wall' and it leaves a sour taste when I think of Subaru now. The same goes for Subaru UK (ie. the IM Group) - no support and terse emails. Overall, terrible customer service. On most of my vehicles I've driven since the 1980s, I've always had discs lasting 50,000 plus miles - no issues.
Maybe it's just this particualr car (I'll be selling it before the next service is due), but the service costs have been around £1000 for the last two services - ridiculous.
Anyway, best of luck with yours. As I say, there's alot to like about the full ICE subarus.
