The most expensive proposition was a new windshield, but your particular insurance could solve that. Spark plug replacement was a surprise as far as cost is concerned. I've routinely changed the oil and cvt fluid once. No other maintenance issues. I love the car. Incredible roominess in the cabin and very capable offroad when needed.

Pros: no other maintenance issues, capable offroad
Cons: expensive windshield, costly spark plug replacement

My 2015 outback has 140k miles. I just did spark plugs and belt, brakes. That's the only maintenance I've ever done other than tires and batteries.

When I started the vehicle up, it woke up really aggressive, there was a strong gas smell and it stuttered badly when driving her, along with the check engine light flashing at me when I did the test drive.\n\nAfter taking out the coil pack, I found that there was a lot of crap inside the springs within the boots...looked like dielectric grease gummed up by the previous owner. After cleaning all those springs and making sure they were straight, I took the new Spark plugs out (Champion Copper) I rechecked the gap and they were all good, after putting everything back together the old girl started up quick as hell, no shaking or anything. I drove it for 15 minutes and I had no issues whatsoever.

Pros: started up quick as hell, no shaking
Cons: strong gas smell, stuttered badly
