New Jeep owner and I have some questions

I've been doing a lot of reading through several forums so finally wanted to ask my own questions to maybe limit responses to a thread I can bounce back to for info.

Firstly I just purchased my jeep used with 47,000 miles. It looks as though it was babied since day one and the driving experience I've had so far has been amazing. I purchased it from a Jeep dealer used off the lot.

Prior to purchasing the jeep I enquired and was told that every recall has been dealt with and that any updates had been applied. It seems several people have had prior issues with DEF and that many felt it was from lack of testing the product before selling it. Have those issues been resolved either through recalls or software updates? Anything I should know going forward? Am I safe to purchase DEF that's recommended in the manual and do it myself or should I only go to dealers?

I also wanted to know if anyone has used extended warranties and if they are worth it. Currently it still has it's 100k warranty but not sure if I should look into other options. If so what would you recommend?

Any other ins and outs I should know? I have the 4x4 overland and think it's incredible. Very happy with the look, feel, and current operation of it. I'm down in Houston, Texas so no mountains or severe cold temps in my area.

Anyone using the GDE Tune and if so what have you thought? While the increased power and mpg seems nice I'm actually more curious about what it does mechanically for the engine. Does it manage to solve any ailments that OEM drivers have had in the past?

Thanks for the info it's greatly appreciated!

Re: New Jeep owner and I have some questions

1. Drop by the dealer to make sure you have the latest ECM firmware. No cost to you.
2. Have the dealer look up the maint record to see if your CAT has been replaced. Caused by a P20EE fault that won't go away.
3. Look for the link in these forums for the NAV firmware update. It will determine if you are due a free update.
4. Buy DEF blue at autopart stores do it yourself. Wait till you get the 500 mi low DEF warning and then put 5 gal in at a time so it doesn't spoil in the tank. The stuff can go bad when it's hot out.
5. 3.0 diesel is a new platform so I along with many other purchased extended warranties. Look for links in this forum to see how much and where folks are buying them.
6. Buy yourself a $70 OBDII scanner that communicates with your phone to show codes and allow you to clear codes too. App's also allow you to view real-time engine parameters. This is a recommendation for any modern car owner.
7. If you are doing any serious off-roading, look in these forums for the DEF sensor protection plate. Jeep routed a sensor wire UNDER the frame; below the passenger seat. Dude on here offers a plate you can bolt over to protect the wiring harness. Crazy design, but true.
8. Have dealer check records to see other maint that should have been done every 20k miles such as replace fuel & cabin A/C filters to name two. Refer to your OM for others. Both are easy to replace by yourself and parts are abundant online.
9. Several folks on here have the GDE tune but it is a little pricey but very very good. Mileage reports from folks are off the hook good like another +5 mpg. You have to send in your ECM. A way around it is to buy one from a parts supplier and send that one in. I think it will save you $150 overall. By my calculations, one will need to drive another $50k mile for break-even ROI, but driveability plus other soft advantages make it a very desirable regardless of the ROI term.

I'm sure others on here will add to these suggestions. This forum has been an excellent reference for me figuring out stuff with the Jeep, troubleshooting and determining the best performance modifications.

Re: New Jeep owner and I have some questions

Can't thank you enough for the response it was perfect and a nice little list to keep me busy! I really do love this thing and look forward to making it more than my simple daily driver so the GDE tune is definitely an option on the table. Looking at their site I see the soot pictures and whatnot so I'm definitely interested for the sake of longevity.

I am a newbie though to all of this so what do you mean by "clearing codes" on the jeep? Wouldn't simply clearing it make you get it all over again? Good tip on the DEF too. I had asked multiple times when picking it up that they replenish all filters and fluids which looks like they forgot to do so. I'm showing DEF at 25% and oil with only a few K to go. I bought it in Dallas but live in Houston and luckily they have several Allen Samuel's Jeep dealers here. They said they'd make the phone call and let me get all of that taken care of locally so hopefully while there I can knock out a chunk of this list too!

Re: New Jeep owner and I have some questions

Oh and as far as the warranty goes are there any pitfalls I should look for? This engine has a turbo so that's one thing I've known to look at. So far I've looked at the MOPAR at the dealer, they wanted $4100 for the Care PLUS!!!! and Delta Auto Protect, has high star rating online with around 400 reviews but still, they quoted me $1900 for a zero deductible 5yr/100000 mile warranty which seemed like such a big difference from the $4100 I'm suspect.

Re: New Jeep owner and I have some questions

I got my extended warranty from Allstate. They have monthly pricing in my area of PA. So that's another place you could look for prices

I'll look into but their most comprehensive says it only covers like 650 parts. From what I've been reading if you're going to get a warranty to get an "exclusive" one where it list what isn't covered instead of what is. So far the Delta one was still the best quote but what I was told over the phone about what is covered, like when i asked about he touchscreen, does not appear in the sample that I downloaded from their site to read over. I went to ninjawarranty to see what they come up with. I'm not against paying some of the prices I've gotten but right now I'm more worried about the company themselves.

With the MOPAR plans online I can get them for low $2k's but that's with a $100 deductible. Did you guys all do deductibles?

Re: New Jeep owner and I have some questions

Here is the one I'm looking at from Delta Auto Protect. This is zero deductible and their highest level, seems like anything with a turbo needs that. It's not an exclusive warranty so I'm still on the fence but if someone doesn't mind taking a look at their warranty and letting me know how it compares of if this is missing a key ingredient. Cost right now is $1900 with zero deduct but told if I order with him he'll work it down a little more.

Re: New Jeep owner and I have some questions

Keep in mind these extended protection plans typically cover manufacturing defects....not just failure due to age or mileage. They want you to think that if a covered item fails, it's fixed for free and it doesn't work that way. The older the car, the harder a MD is to prove. And you have to prove maintenance by the book for the life of the vehicle, which might be problematic. Long story short, there is a long list of ways or reasons they WILL deny the claim. With 100K mile factory powertrain protection I would just stick with that. Over 100K miles is going to be hard to prove a manufacturing defect.

Re: New Jeep owner and I have some questions

I don't think you can get an extended service plan from Jeep now but if you can do it. Longest is 8 years/ 120K miles and very reasonable.
I would get the DEF cover plate no matter what. You can break that plastic nozzle off in hard water splashing up or even road debris so get that done first and foremost. Check your owners manual as I didn't replace my filters until I did the latest oil change around 28K miles.
This is a fantastic vehicle and being in Houston you should never suffer turbo issues as the oil should almost always be warm enough to not blow a turbo seal. If you were in a cold climate you need to keep boost low until you get some oil warm regardless of synthetic oil as most pressure relief valves fail to operate correctly cold and you can over fill the turbo housing which forces oil out the top of the oil seal (it is more like a metal snap ring actually) and that is what cokes the turbo up.
Speaking of oil you must use the low ash oils out there and Total, Mobil and Pennzoil have the correct ones. I have used Pennzoil twice and Total once. Oil analysis has proven that the total base number (TBN) to have great life at 10K miles which is the oil change interval. Again being in Houston you will not form a lot of acid in the engine unless you drive very short trips.
I would also add that if this was my Jeep I would change the transmission fluid doing a drain and refill with Lifeguard 8. This is an excellent ZF 8 spd transmission and the only thing that will kill it is poor maintenance. I have considerable experience with ZF transmissions and they all perform well doing a drain and fill every 50K miles. Just Google Lifeguard 8 for suppliers but the one I use is located in CA and the guy sells all types of LG oils for ZF.
That is about it. Mine is 31K miles and I love driving this thing...

Re: New Jeep owner and I have some questions

There is an option through mopar that isn't a bad price. However I don't know how their 5000+ part warranty works compared to the other warranties out there. One of them I received a quote from was 5yrs, 100k miles from now and was around $3400 but was exclusive meaning outside of a few excluded items everything was covered bumper to bumper however I had never heard it was manufacturer defect only vs something just breaking. I don't see how anything that breaks can't be considered a manufacturer defect since the parts are not life limited with defined mileage expectations. If the transfer case or touch screen doesn't have a "expected to last for xxxxxx miles" then how could it not be covered? The whole point of the warranty is that you are paying for coverage over those parts for that amount of time which would mean it is assumed that all parts covered would have to suffer a defect to break.

Re: New Jeep owner and I have some questions

Flying Texan,
I live in Houston as well and the satisfied owner of the very first 2014 JGC Ecodiesel delivered to the state of Texas in Nov 2013. My Jeep now has 38,500 miles with relatively no issues to date. I average 28 mpg around Houston. I have not had CAT or DEF issues. It has been in the shop only twice for fairly routine and minor warranty items. I buy my DEF from Autozone, two boxes at a time. I agree with the purchase of the DEF protector plate, which can be found on this forum, contact DOM42. I also agree with fun2drive, he offered excellent suggestions.

Don't rely on anyone to do your oil changes. After one performed at the dealership (only added 6 qts), I have done my own since, something I had not done in 20 years. The oil filter is up top with easy access, and you can ensure adequate oil drainage and proper levels.

My only complaint is the outdated maps. Other than that, this Jeep is the best SUV I have ever owned.

Back in 2013, I offered rides from the airport for out of state buyers picking up their new Jeeps at River Oaks CJDR where I ordered mine. I enjoyed meeting everyone ; they were from MN, CA, FL, AZ and elsewhere. Fun2drive was one of them. Great guys all of them.

Several of us were able to visit the Jeep assembly plant in Oct 2013 while our Ecodiesels were built but sitting in lots waiting on DEF tanks. It was a great trip. We were a bunch of Jeep fanatics, even me, and this was my first Jeep.

Based on the great result with the Ecodiesel, my wife wanted a diesel. She purchased a 2014 VW Beetle. She loves it for daily commute at 38 mpg and great torque for a bug. But... who only knows what it will be after the VW fiasco fix.

If you have time for coffee or burger, I would enjoy the visit. If you want to get together some day, simply message me through the forum. I work in sales, so I am out and about in all parts of town.

Good luck with your JGC. You will enjoy the Ecodiesel power.

Jerry, aka Brainstormer.

You guys should go to the link HERE. Pick JEEP\Grand Cherokee\2014 at the top of the page. I entered my VIN, downloaded two programs to my PC then to a flash drive and the NAV updated no problem. Your head unit (select Media\USB) takes a minute or so to read the flash, so be patient.
