I've owned a 2006 and 2010 Twin Cams. Drove them extensively, gave them average maintenance and love. Never had any of those issues. Momma has a 2008, Toyota, Highlander, we bought for its supposed bullet proof reputation. I have owned only one other vehicle in my life I have hated worse. Major issues with everything on it since buying it brand new!
No doubt some machines will break, some catastrophic. Most will give years of reliable service, but eventually something is gonna break. Chance we take.
