Jeep grand cherokee 2012
HI all from Sunny cape town. i have bougt a 2012 Grand cherokee 3.6 V6 with 60k and recently i have been feeling and hearing a strange clunck sound coming fom what sounds like the diff especially on pull away, i sent it in for a check and they did a firmware update that was suposed to have sorted it out, but guess what, its still there, they did some more diagnostics and anothermfirmware update, initially the first few km were fine but noticed that in slow traffic driving i could still hear the sound , but now i can hear two clunck sound ,MMMMMmm and the engine throtte response seems to be now very sluggish. So back to the garage again. seems like this is an electronic issue , but im not sure if they know how to diagnose correctly.
