I hope your next car doesn't give you any problems. (not possible). Think about it all cars have the same parts and they ALL break. These motors are solid and that's the main concern. Everything else can be replaced with a cheap tool set from Walmart. Over 90k on my jeep and never had any if these problems so I guess I'm lucky but I maintain and um.... I'm nice to her. Go ahead buy another car SnD hope nothing is wrong. I was looking to sell my wk as well but I thought, hey it runs I know the issues with it, if u bought another who knows. I know my jeep pretty well, its not a big deal to swap out a part. That's all it is. Electronic stuff lol different story. Still a great car. Also for Laredo, heavyduty jeep=heavy duty parts.

Cool Re: Jeep WK reliability

Dude I work at a service department.... We have more than enough business all the time we don't lie to rip people off and we try to treat our customers right but we are not in the business of holding peoples hands either... We are a business just like where you work and we need to make money too for our wife and kids... So quit crying stealership prices.... As boomers said heavy duty jeep equals heavy duty parts and if you can't pay to play than you bought the wrong car... Sounds like you need a cheap Korean car.... I can tell you the German place i work has a higher labor rate than jeep as well as higher parts prices so to hear you complain about jeep service is ridiculous to me.... I have a great experience at my jeep service over and over.... Yes i have a 2009 4.7 Laredo X leather that had 7500 mi when i bought it and Im up to 12,500 mi now....I've done oil changes, diff fluid services, transfer case oil changes, i even did the 30,000 mi spark plugs just cause its been 3years... Haven't had a single issue mechanically and yes i know only 12500mi but i also bought the extended warranty for 7 years 100k from when the factory warranty expires which mine ran out last Sept... for $2500.... Ever thought of researching and investing in one of those? Some are horrible but there are great third party warranties out there that yes trust me they will easily pay for themselves if you plan on keeping the car for a long time... Also some you can do a one time transfer so if you sell you can transfer and it makes a great selling point to whoever is buying your car..... Peace.

There was a time (....back in the day, to coin a phrase) when aftermarket parts, like NAPA, were heavier duty than the marginal quality from the assembly line. I preferentially used the most durable ones I could find.

Now, I see that OEM MOPAR parts are more robust in many cases than the chain parts stores. The shocks on my '08 WK are one notable exception. They are hydraulic and will be replaced with montube gas shocks when they go.

I probably need to get back with NAPA to see what their current replacement parts look like. I know the NAPA Gold oil filter is a WIX, so that is a safe choice.

My dealer's service and parts depts are outstanding. Keeps my WK on the road.

It's good to see a few of you are having good experiences at dealerships, most I've gone too have been awful warranty or not, I love jeep but hate Chrysler, jeep needs to be there own brand and man up and use some quality parts that seem to have better quality control, I bought several mopar parts that were bad right out of the box, but than again I've bought some more that we're great. The general consensus seems to be 60/40 in favor of dealers treating people unfair which IMO they are doing. These aren't facts but my 2 cents

I'll give them a plug for all of their excellent service work, reasonable rates, and good repair parts pricing:

in Midland, Michigan, it's Feeny Chrysler/Dodge/Jeep/Ram just North of the Midland Mall. This is how it is supposed to be. Rick is the Service Manager.

The franchise (now no longer a dealer) in Bay City was terrible.

You will hear me criticize Jeep for their design decisions / assembly quality, but it's the dealer who has been able to rectify most of the most serious of these issues. They frequently go to bat for me with MOPAR

Re: Jeep WK reliability

I work in a big chain parts store. All day I deal with people with every single car you can think of come in with codes and problems that need to fixed. This is part of owning the vehicle. No matter what it is.

If you don't maintain it properly I don't care if you but a Ferrari it will break down and it will cost you more then a Jeep ever will to fix. (I see this all the time younger guys come in with BMW or Mercedes with alot of miles and are shocked at what parts cost).

Best advice I can tell anyone is keep up with the regulars that is the most important. That includes all fluids. If you aren't mechanically inclined go to any part store and buy/order a Haynes manual and start learning this will save you money and help you understand more about maintaining a vehicle.

Sorry your jeep has problems. There is alot of them on the roads I am sure a few will have problems more so then the other (LEMON)!!!!

Re: Jeep WK reliability

Walt your experience has been pretty terrible... Cylinder heads, fuel pump, o2 sensors three times in 60k. I wonder what the hell is going on with your jeep? Have you figure out any answers?

No fuel pump; only all new injectors ().

It had to do with the O2 sensors and getting the exhaust properly sealed. Now we are down to the joint between the exhaust manifold outlet and the Y-pipe leading to the catalytic converters. There is no gasket in the '08 model year.......just metal-to-metal. It's sort of ball shaped, so if anything is even slightly out-of-round a leak occurs.

BTW: I did find some hi-temp gasket material if anyone wants to try it:
Percy's High Performance Carbon Gaket Material #68006. Cost $10.95 for a 10" x 10" sheet from Summit Racing. If I every need to make a custom gasket for that particular exhaust joint, that is what I plan to use.

Service manager believes the O2 sensor response time error band is too tight. That is, if it were opened up just a bit, there would be lots fewer DTC's. These DTC's go through PENDING, then SET. If there are not 2 cycles of PENDING, the DTC clears and no MIL appears. Unfortunately, that algorithm is burried deep in the PCM and so is classified as "emission-related" for EPA purposes. As a result, Jeep will not allow dealers to alter it.
I believe many of the changed components really did not need to be replaced. However, the Chrysler technical representative (and there were several during this period) wanted to do it to eliminate the other possibilities. The HEMI is under lifetime limited powertrain warranty, so essentially no cost to me, but it was a complete PITA taking the HEMI in every week to try something else. I couldn't demand that Chrysler do a particular fix or I would have had to pay for all of this. I recorded the problems and had to let the technical service representative determine what to do next.
For the last year, it had been pending O2 sensor 1/1 & 2/1 slow response DTC's (P0133 and P0153). Just had those joints re-tightened about a month ago (no charge) and the symptoms disappeared (again).

I think working with the dealer's Service Manager and lead technician was my greatest asset. I've been through the '08 FSM cover-to-cover (all 6 volumes) several times. As an engineer & gearhead, this is very intriguing.....as an owner, I should not need to go through torture.
I believe this mess has cost MOPAR 2-3 times the original sale price of the Grand Cherokee Limited. I had offered to give them this one and substitute an '09 under lemon law provisions (because the '08's were out of production by that time). They insisted on trying to fix it.
The cash register continues to ring up to MOPAR's account (at ~96K miles currently), but I have done everything they have asked (and more), so no bad feelings on my part for holding Chrysler to the warranty provisions.

Passed the 5-year warranty inspection with no issues. At the time of the mandatory 5-year powertrain warranty inspection, I gave them back a complete service history, maintenance log, and list of replaced components. Since they had done 95% of the work, it wasn't really a big surprise.

I know this is verbose, but maybe another WK owner new to the HEMI world will benefit from my experiences.

Re: Jeep WK reliability

I wonder why they haven't replace your main computer and entire wiring harness. The mechanic they have working on your jeep is one unlucky scmuck... Taking off the exhaust manifolds in the worst. It is a crap situation because you are stuck with this jeep, it isn't worth crap if you sell it. Nice how they sold you a lemon.

Re: Jeep WK reliability

I pushed several times for a new PCM. It was re-flashed several times (including updates) to ensure all the programming is correct. One thing I learned is that the same PCM hardware is used on several MOPAR platforms. Thus, when the dealer replaces it, they have to download the appropriate software using your Jeep's VIN.
Apparently the StarScan does some sort of pre-programmed test to verify that the software has been properly installed. This was run on my PCM and found to be acceptable.

I'll probably run this '08 WK HEMI for several more years. Has ~96K miles. I would like to have the 8-speed xmission and the new diesel, but want to let some of you other guys do the developmental testing on them first.
