All Chevy & GMC vehicles + Dodge Durango, Jeep Wrangler, Ford Traser, MINI Cooper the most unreliable. Medium reliability were my 2 Mitsubishi vehicles, Mazda truck, Audi A6 and Nissan truck. Jury still out on my 2014 Hyundai Santa Fe Sport..so far, so good. This all over a 25 year period, including some vehicles I bought for my kids.
