Intermittent Engine Revving Noise - 2014 JGC Laredo Diesel 3.0l
I have a 2014 Grand Cherokee 3.0l Laredo Diesel (Australian model) which has done almost 42.000 kms. It has recently developed an intermittent engine noise, sounding like its revving too highly, that continues for a few seconds after the ignition has been turned off. Its not there all the time - since first arising its been happening about once a week. If I turn the ignituion off then back on again the noise does not reoccur, at least not for another week. Very strange. Any advice would be most welcomed. By the way it has had all the required services as required while under warranty.
