Faults:
Coolant sensor bad.
Gear shift lever detent lock (covered by recall notice).
Wouldn't officially call it something going wrong, but after purchase, did a complete visual inspection and service on the front and rear diffs, transmission, transfer case, all filters, all fluids changed, and flushed/filled radiator. Also replaced front rotors, as this is a typical problem area for ZJ's.
The vehicle has been extremely reliable and very fun to drive!
General Comments:
I am another happy, extremely satisfied 5.9L owner, and can say that this Jeep is everything I require out of a vehicle for utility (okay, so it can't tow my 38' fifth wheel LOL), since it can simultaneously tow 5,500# behind it and haul my family and all of our gear on vacation, and also that it has an unstoppable 4-wheel drive system.
Add to it, that even as a 2+ ton SUV, it is faster than many cars in a straight line, and it's an unbeatable combination. A true "Sport Utility Vehicle"; capable of tackling any trail, hauling anything the average person would need it for, so simple it can be worked on by the average Joe for basic mechanical repairs and maintenance, and has a touch of "Hot Rod" thrown into the mix!
A little long in the tooth now as an 11-year old vehicle, yes, but mine has 134k miles and has never let me down, as I am a stickler for maintenance.
I plan on getting another one in the near future to keep 100% stock (with the exception of the stereo system), as I'm about to do a complete performance engine build on my current one; in a nutshell going to stroke the 360 CID/5.9L engine into a 408/6.7L and upgrade the tranny to handle the increased power I'll have at my disposal! A true sleeper that is going to surprise many more unsuspecting people than it already does!!!
