Transmission shredded at 66000KM (6K over warranty) $4500 for replacement! Very common fault on these vehicles. Make sure the ONLY trans fluid used is Chrysler 7176 (pink in colour) change this every 25000KM MINIMUM to prevent, no generic substitutes!
Engine speed sensor. When this fails it causes "limp mode" - stuck in 2nd gear. To clear the limp mode so you can go to repair shop, disconnect and reconnect battery.
Back door struts, sticking (~50000KM)
Rust on door slide tracks for back doors. Caused by door wheels grinding road grit & dirt into the paint. Make sure you flush the slide recess with hose and grease the tracks well to prevent.
Front indicator bulbs - These are almost impossible to change through the stupid hatch in the wheel well. We have 3 lost bulbs which are rattling around in the light lenses from trying to change these stupid things. Squirrel sized hands help here!
