Ok,
When you post in this thread it must be related to a high level area as described below or in the misc section and then describe in detail and/or relate to a known Technical Service Bulliten (TSB). Copy the entinre section and add your comments to the sections.
BODY EXTERIOR -
INTERIOR -
- Cloth seats stain very easy. TSB on this for the dealer to wash for you once.
ENGINE -
3.0 CRD -
- Swirl motor for the Turbo may make a clattering noise as this is the vaccum pump on the blink. Also delivers very poor performance.
- Injectors need to be reprogramed when they arre replaced or they will not talk to the computer.
3.7 -
4.7 -
5.7 -
- Is a known HEMI shudder but not sure if this affects the export model.
6.1 -
TRANSMISSION - QuadraTrac (QT) or QuadraDrive (QD)
- Service 4WD System light will illuminate and chime regularly. TSB to re flash and tighten connectors
TRANSFER CASE -
SUSPENSION -
- Rear spring mount isolators creak/squeak, TSB fix for replacement isolators
STEERING -
ELECTRICS and ELECTRONICS -
- PCM eaten by battery acid. This is of note and has happened to me as an isolated case. The battery was either overcharging or leaked during servicing and hence the PCM is directly under the battery and it ate the aluminium cover and the PCB within. This caused no end of fault codes as well. Also the wiring harness on the left hand side facing forward of the vehicle had to be replaced due to the acid ingress.
- Window regulators on the front neede replacing
WHEELS and BRAKES -
- Brake Rotors need machining front
- Minor shudder when braking uphill
ACCESSORIES -
- If you fit the factory nudge bar you cant fit the factory rated recovery points at the same time.
MISC -
Lets start populating this.

Don't know how many times I have had a re-flash but the "service 4wd system" warning comes on every time I take mine off road

if u fit the factory nudgebar on a car with parktronic, it sends the parktronic crazy cause the nudge bar goes straight over the sensors
3.0LT CRD: trans wiring harness seals leak trans oil on a regular basis.. updated adaptor fixes this problem (we hope)
3.0LT CRD: seal on the inlet of the turbo lossens and causes an oil leak from the induction. fix: keep the hose clamp tight or fit new seal

All WH owners with a QII transmission should check the seal where the electric enter the trans for oil leaking out thru the seal.

Turbo wind between 1500 & 3,000 rpm

Cherren is is that the airbag light comes on or is it possible that it's actually all the lights that came on and then go off in the same orders as the self test, with the airbag being the last one? Mine has done that 4 or 5 times for no reason and Jeep replaced the ignition switch yesterday as there has been a few reports of them shorting out.
