15: Jeep Wrangler
The Wrangler has long been a popular off-road SUV with a lot of potential but recent models have been problematic. It should be expected that any modern SUV will have more expensive repair costs than the classics, but the Wrangler is taking it to the next level (via Hot Cars).
There have been problems with the seals along the removable top, the engine overheating, and several electrical issues. There have also been issues related to the 4WD system, and these are among the most expensive to fix.
