We bought a 2005 Jeep GC CRD 3.0L auto 2 weeks ago. The day after delivery, the kick down started to malfunction. Even by depressing the pedal to the floor no kick down whatsoever. If you switched off completely and then on again, the problem was cleared. However on 1st Oct on using it no kick down at all no matte what I tried. Vehicle changes gear okay up and down as per normal, just no kick down.
The car dealer took the Jeep to the Jeep franchise on 3rd Oct and they have had it ever since and cannot find the fault. On 4 test runs, the fault showed up on the second test run while the mechanic was driving and again on the 4th occasion. Problem is no fault code is coming up to show where the problem lies.
As we tow a caravan (trailer) we really need the kick down plus for overtaking. It seems no one else has come across this problem previously so we are stuck as piggy in the middle!
Jeep dealer still has the Jeep and is no further ahead with it than they were on Wednesday!
