Every car model sold has ones that disappoint people. Stinks. The 90s Grand Cherokee - the ZJ - was ground breaking at the time. But, like all new from scratch models, they are plagued with issues that come up. Later generations typically work those bugs out.
I have a 1995 Wrangler today that I bought new. $12,500! No radio, no ac, no airbags or ABS. Safety? Sure. Still have it today and drive it as much as possible with 250k on it now. I've owned two 4 door wranglers, a 1999 Cherokee (shoe box), and some others.
