Enforcer, it would seem the "diplomatic" approach is not working with CJD Aust nor with your dealer. Sometimes complaints are simply ignored even though there is a legal obligation for them to action them. I think they've pigeon holed you!
Might I suggest an old fashioned remedy which worked for me +20 years ago when a dealer reneged on a warranty issue.
On a Saturday morning when the dealership showroom is "abuzz" with prospective Jeep tyre kickers, take your wife and kids to the dealership, park your car in their yard near the showroom and walk in......then:
- with a quiet voice and a smile ask for the principle or manager
- with a quiet voice tell him / her you will not be leaving until your ACC issue is resolved. (remain at the main reception counter, don't let them heard you into a quiet office) If he / she tries to fob you....
- with a slightly louder voice tell them their behaviour is unacceptable (at this point you'll notice his / her body language change - head turning to see who's listening / watching and eyes shifting sideways). Point to your car and explain this has been a major fault with the car for months that they have ignored and it was their service dept that damaged it in the first place. If they still try to duck shove you.....
- with a louder voice (smile removed) gently slap the counter with both hands tell them you will not be leaving the dealership until they guarantee "IN WRITING" to repair the ACC within 1 week or they will replace the car with a new one and that is it unfair as a consumer who purchased a NEW Jeep to to experience such poor after sales service. (this will prompt them into action as the
- As the main driver of the car with the kids, your wife may want to make a comment or 2.
The main thing here is at all times keep your cool and don't give them any legal cause to throw you out the door.
The above example may sound like a lot to do but it plays out very quickly and given the right circumstances just may get you the outcome you're looking for. The last thing a dealer needs in a crowded showroom is an "incident". Don't forget make sure your wife and kids go with you, it will add to the atmosphere!
Worse case scenario, on the following weekend, park your car on the street outside the dealership with a sign on it saying something to the effect... I BOUGHT THIS NEW CAR HERE AND THEY CAN'T FIX IT!
