I started my 1999 jeep grand cherokee in the morning to warm up. the vehicle was in park, but the emergency brake was not on. i went back inside my house while my vehicle was warming. when i went back out to my vehicle i noticed it was no longer in my driveway. the vehicle was in my neighbors yard! i couldn't believe what had happened. when i got in the vehicle to move it out of the yard, it was in reverse. luckily it did not have enough power to make it up the bank of the yard or it would have went through my neighbors house. no one was injured nor was there any damage to the jeep. it jumped out of park and slipped into reverse on its own. i am 100% sure of this!! i bought the car bc i wanted something safe to haul my family around in...we just had our first child. now, after this incident, i don't feel safe at all. my wife is extremely afraid of it now especially since we have a newborn...nothing like making a huge car payment for something that drives itself. i did some research on the net and it appears that i am not the only person who has experienced this problem. the figures are now approaching 1000 reports of this type of incident. i like the jeep, i wish something could be done about the problem. if nothing is done by chrysler in the next few months i am going to sell it bc my wife won't even ride in the car anymore..especially with the baby. if i do sell the vehicle, i hope it does not injure or kill of the new buyer!! chrysler has problem, they need to fix it before people start getting seriously hurt.*ak

Rotors are shot and it seems i'm not the only one, 4 wheel drive will not disengage even after i shift it out of 4 wheel drive (large popping noise when it does disengage). rear wiper works sometimes and othertimes it won't. now i'm being told the transfer case is leaking and needs to be replaced (seal and shaft). at 53,000 miles these items seem ridculous. i've checked around on the internet and it seems like others have the same problems.

My 1999 jeep grand cherokee laredo had a new differential install edat 15,000 miles; two new front rotors at 36,000 and should have been done way before this; back brake drum cracked at 36,000 miles; front rotors redone again at 42000 miles; and now the motor at 52,000 miles. we had not indication (noise, etc) of the motor going, i was traveling aroung 5-10 miles per hour turning into our road and it felt like something heavy dropped out of the vehicle, it sounded like metal going through a fan. a piece of the block fell out onto the road and the people at the local dealer said they had never seen any thing like it before. it was like a bomb went off inside the motor. my question -- should chyrsler be responsible for this motor, it will be in the range of $6,000. thank you.*ak
