Jeep Renegade
2.4-liter Tigershark with MultiAir valve train. Modern on paper, in practice an oil consumption scandal: piston rings don't seal properly, up to 1 quart per 1,000 miles disappears. $8M class action settlement. Primarily 2014-2018. Oil warning comes too late — engine can stall without notice.
More charm than substance
The Renegade looks fun, underneath it's Fiat engineering with teething problems. 9-speed jerks, 2.4L drinks oil, electrics play tricks.
