Believe it or not but the Cadillac Escalade has also made our list, being so unreliable that it is the worst in its class. Its main issues include a problematic transmission, rough shifting and less than ideal power equipment and in-car electronics. It also comes with less than ideal cabin space, uncomfortable second-row seats, and a cramped third row. Fortunately, the longer ESV is also available. However, luckily for Cadillac, it does come with a powerful 420-hp V8 as well as an impressive tow capacity.
