Problems with the 1999 Jeep Grand Cherokee's driveshaft are well-known among Jeep owners, but many dealers, and apparently the manufacturer, are failing to be forthcoming in providing fixes or an official recall. Driveshaft on this vehicle binds under many driving conditions, making loud "clunking" noises and resulting in unsafe vehicle "lurching" as the driveshaft binds/unbinds. The dealer's first attempt to fix the problem was only temporary - it reappeared within two weeks. Dealer now promises a factory fix "sometime in January" - a totally unacceptable response.

Rear-back window leaked, reseal failed, had to remove window and reseal, took 4 days. Front differential failed causing front tires to hop during tight turns, diff replaced took 3 days. When stopped at a stop light truck lurches forward almost as if hit from behind, this happens 1 sometimes 2 times at one stoplight, engine revs also increase when this happens, dealer cannot fix. Gas tank is very hard to fill the pump stops before it is full and many times gas spills all over truck and pavement causing a fire hazzard, also gas cap is very hard to remove.
