Jeep Grand Cherokee WH (2005-2010) Questions & Answers

That can be high miles for the diesel. I know the earlier ones had a few issues.

I know of several diesels that have travelled near and over 300,000 k's, no probs. I own one, although mine has only travelled 145,000, If it's a Limited you get QuadraTrac 2, with mid, front and back diff locks, also wheel rotation monitoring. The best comfy 4WD available. If it's a Laredo the 4WD is still very good. I love the Mercedes diesel. All up a great vehicle.

Hey guys i am not going to tell everyone what to do, but I will give you a perfect example October 2018 took my jeep grand Cherokee limited to Caroline springs jeep in vic. With a windshields wiper sensor issue they told me it's the sensor so I said order new one for me few weeks later i get a call your sensor is here ill book you in fine went in sitting there few hours for the service guy telling me th ed gel pad that glues the sensor does not come with It I told him what you didnt know, anyway I told him I would find one because jeep wanted me to replace the windscreen that comes with the gelpad on it. I said your joking I'll find one I emailed a company in USA and they gave me a name of a company here in melbourne so I rang them and bought 2 for $90 got them to install it, then jeep manager came and said it's not working we don't know why we think it's your new head unit I told them are you guys stupid I've had that 3 years the rain sensor just started. So went to my friend at Alan Mance Motors in Footscray Vic he had a look and asked me how old is your battery I said 2013 the dealer replaced it when I bought the car. I had no idea what battery had to be in a jeep.

Here we go it worked out well I was having problems with battery going flat, so we changed it but my friend said it's 2 times the size you have now and according to the charts that's the right one bloody huge we replaced the battery and guess what my rain sensor started working so jeep dealers have no idea how to f is there own cars none of the mechanics even checked if I had the right battery and on top it was a cheap lion battery from China never buy them. The old battery was not big enough to power the car system with the canbus feeding power to everything so I'd say to everyone please make sure you have the right battery in your jeep because eventually it will stop supply power to your car it's amazing what a cheap battery can do to your cars system. Just beware of your battery replacement make sure you have the right battery it's huge. So all I really need is to get a software update so it will reset my jeep system amazing when you have the right information given to you.
I really hope this helps some of you guys on this forum. Jeeps dealers have no idea have not found one yet that knows how to fix a simple issue. That's why I take my jeep to Alan Mance Motors in Footscray Vic.

Hi David check the front tailshaft rear cv joint very common for grease to come out. If ok check transfer box oil.

Hi Craig. i currently have a 2009 jeep grand Cherokee diesel with 170, 000 k on it and it has been the best car i have ever had, i live in Tasmania and it has done mutable trips to Queensland towing a 3.0 tonne caravan, and it has been faultless, the merc engine is something special, never uses a drop of oil. i get it serviced every 10,000 k.average fuel consumption without the van is 9.1 liters per 100 and with the van is 13.9 per 100. excellent ride great vision, i normally get around 50,000 km from a set of tyres. this is my second jeep, first was a 2006 model with same engine, that one had over 200,000 k on it when i sold it and again no problems .i will defiantly go for one that was built before 2011, good luck Mario

Thanks Mario,
Appreciate your input.
Have a great day.

Try turning the key on and off a couple of times and watch the glow plug light. This gives the glow plugs extra heating, hope this helps

Hi there, I have a Mercedes diesel which displayed the same symptoms. The solution was replacing the O rings on the fuel lines on the inlet side of the fuel pump.
What happens is that air leaks into the fuel lines past the hardened O rings while the engine cools down. When you start up the next morning the engine starts up normally but then cuts out almost immediately thereafter. It then requires several cranks to get started. If the car is driven during the day it usually starts up first time as not enough air has accumulated in the line.

This is a very easy and cheap fix. Just undo the clamp bolts holding the (fragile) plastic fuel lines and replace the O rings. I am referring to the fuel lines on the inlet side of the pump. I.E. from the filter to the pump as well as from the return from the Rail to the pump. You do not need to replace the fuel lines, only the O rings.

Be very careful with the flimsy plastic end fittings on the plastic pipes. You do not need to use special or Viton O rings. Get them from any supplier who stocks hydraulic seals. Do not use O rings suitable for brake lines. They are not suitable for oil and diesel.
