Jeep Grand Cherokee Diesel Problems

Our checks indicated that Shell Helix Ultra 5W-40 ECT C3 is recommended for the 3.0-litre turbo-diesel engine. If you are still concerned talk to your dealer or contact FCA on 1300 133 079.

Based on the Chrysler claim for fuel consumption the diesel comes out in front by about $600 after taking into consideration the higher upfront cost and higher servicing costs.

Yes, it is a common-rail diesel engine and turbocharged.

My view is that unless you are doing high kays it's not worth buying diesel models. The Grand Cherokee diesel is around $4000 more expensive than the petrol V6 and a rough calculation based on the higher cost of diesel compared to PULP and diesel's lower consumption says that it would take you more than 100,000 km to recoup that cost. On top of that diesels are more expensive to service.

The noise you talk about seems to be common to all modern common-rail diesels. The first time I heard it was when a neighbor started his Toyota Hilux one morning and I thought it had run a bearing it was so loud. The fix is usually to replace the injectors, but that's only temporary. There doesn't appear to be much that can be done about it.

No, it's not normal. Take it back to the dealer and ask that they recheck it, and if nothing shows up as being abnormal, ask that they consult head office.

It is common for modern CRD engines to exhibit a tappet-like rattle when cold, they all seem to do it, and it appears to be the injectors. The first time I heard it was on a Toyota HiLux and I thought the engine was about to let go. Take it to a diesel mechanic and see if they can recalibrate the fuel flow when cold.
