I think this brand used to be very good but now, think again. Got a 2016 subaru, its soon 3 years in a few weeks. I noticed there are a lot of rust at the bottom of the car, exhaust pipes and other areas where I can see the part has turned rusty. I showed to the dealer and they said Subaru rust coverage doesn't cover that. That's misleading because when I got the car, they said 3 years warranty on rusts for the whole car. The car still functions but I am disappointed.
