The first generation Jeep Wrangler used a 3.8L V6 engine which was derived from the Chrysler minivan in 1991. The 3.8L V6 was mated to a six-speed manual transmission or an optional four-speed automatic transmission. This version of the Wrangler was significantly heavier than its predecessors, weighing more than a half ton. However, it was not nearly as unsafe as the previous generations.

The second-generation Jeep Wrangler has a series of problems, including a defective fuel filler. Additionally, it suffers from death wobble, rust, and a cracked manifold. In addition, the Jeep Wrangler also has a poor rating for safety in the side crash test.
