Helped my father purchase a 2019 Forester earlier this month. He opted for the base model this time. My dad previously had a 2011 and 2005 Forester Limited, putting over 150,000 miles on each. The 2011 was a bit problematic - had a check engine light early on that the dealer was not able to resolve after multiple visits. Subaru replaced the engine under warranty. He had intermittent AC problems (specifically leaks) for the remainder of ownership.
I will say that the 2019 Forester was difficult to shop for. Many of the local dealerships had $2,000 worth of add-ons including remote start, paint and fabric protection, pinstripes, door edge guards, VIN etching, etc. - and refused to budge from the overly inflated prices. With other vehicle makes, it was easier to negotiate or even just "refuse" these add-ons, but the Subaru dealers left little room to negotiate.
For those considering a new Subaru, we were able to call Subaru Customer Service and request an owner loyalty coupon worth $500 off the purchase of a new vehicle. They verified ownership based on current VIN number and e-mailed us the coupon.
It's a very nice vehicle and will serve my dad well - just more challenging to purchase than other makes including Honda, Toyota, GM, Ford, Chrysler, etc.
