I bought a 2016 SR5 4Runner with 80,000 miles. It only had one owner, but it was on a ranch in Eastwood, NM. Good thing: very little deicing chemical exposure, and very low humidity. Bad thing: clayey fines accumulated inside the hatch. The rear window goes down, but won't go back up. I took the panel off the hatch and pushed it back up, and then took it to Toy Care Care in Centennial, CO. They are going to replace the motor and the cables for $1,300. I'm going to do it, but just wondering how long that new motor will last? Anyone have a feel for the durability of that repair?
