Problems with 2006 Jeep Grand Cherokee ENGINE AND ENGINE COOLING

2006 jeep grand cherokee 65th anniversary edition: 15 days off the lot when while driving 15-20 mph engine completely died. i could not steer to the side of the road. there were no warning lights or any indication of a problem. dealership diagnosed "major internal engine failure" and replaced with new engine. about 4 months later rattling sound turned out to be catalytic converter that needs to be replaced. still waiting for the part. suv still does not drive 100%. sometimes when i step on the gas the truck does not respond right away. *jb

My wife and i purchased a 2006 jeep wk 4x4 on feb 20 2006. as soon as we left the dealership with 150 miles on it the air bags malfunctioned and had to be repaired. about 1 week after the repairs they malfunctioned again and where fixed again only to malfunction 2 more times and the dealership said there was no problems and cleared the codes. at the 3000 mile service there was an oil leak on the front crank seal which was replaced. it has also been in the shop 5 times due to an engine malfunction light in which case there was a multiple cylinder misfire, the dealership said there where no problems and cleared the code every time only for it to come back on. i just picked my vehicle up from the dealer again because the crank pulley and dampener where wobbling real bad and the check engine light was on again for the same reason. all repairs where made and after i left the dealership 15 miles down the road the light came back on. the transmission shudders when i'm stopped and shifts real hard. the dealership said its fine and there is now evidence of that. all these incidents are ongoing since the day it was purchased. *jb
