Jeep Grand Cherokee 2011 Problems

We'll pass your comments on to Jeep and ask for their assistance in finding a solution.
 

It's always a good idea to report a problem, if you don't there's no way you will get it fixed, and as you say, the more people who report a problem the more the chances of it being taken seriously. In your case I would guess the dealer doesn't know how to fix the problem and is hoping you will go away. It's obviously in the driveline, could be a computer shift calibration problem, it could be a number of things.

We haven't had any other complaints of this issue, which doesn't sound normal at all. Perhaps other owners could tell of their experience; in the meantime step up the pressure on Jeep to give you a believable answer.

Chrysler told us that their recommended servicing intervals are based on advice from the factory in the US, which states 10,000 km for a diesel and 12,000 km for petrol models, with six months applicable to both. They say it is in line with the industry standard, and reject your claim of ‘over-servicing’, and we can’t dispute that. But it’s a good idea to check servicing costs before buying, after all they’re costs you will have to pay down the road.

I think you'll find that supplying the complete assembly is easier and cheaper for Jeep because it then has to maintain fewer stocks in its spare parts warehouse. Added to which they probably make more money from supplying the assembly then they would from simply supplying the pump on its own. The internet is a good tool to use for anyone needing spare parts because you can often source them more cheaply from overseas than you can here.
