Ecodiesels with >50K miles - changes in experience

There have been a lot of niggles with the '14 Diesel Jeep mainly around the DEF in the first year or two of ownership. It seems to take cat replacement in most cases, and some other measures including getting used to how much DEF to fill at a time, to get over these.

I am considering buying a Jeep with 50-60K miles on it. The big risk there is that if these niggles persist, I wouldn't have a warranty to back me up.

So two questions:
1. Anyone who experienced all these issues, but saw them go away and stay that way beyond 50K miles, after appropriate fixes? What fixes were needed?

2. Any other new issues that cropped up around the 50K mile mark? The 60K service is a major one with entire suspension etc. being inspected - does any part of the suspension (especially on the air suspension models) need maintenance or give up at that point?

Emissions warranty is 8yr/100K miles. Powertrain warranty is 5yr/60K miles. Bumper to bumper warranty is 3yr/36K miles. Someone will correct me if I'm wrong.

I am just over 100,000 miles on my 2014 Turbodiesel. I had the CAT replacement (under emissions warranty) at 40,000 miles and a transmission re-flash for "shuddering" just after that.

I've experienced NO problems since then. I believe I had to pay out of pocket for the re-flash, maybe $150, but only regular maintenance since then.

I'm over 50K, I Deleted the damn Emissions system and got the appropriate TUNE. So far all is well and the only issues I've had for entire ownership history was the emissions. I avg at least 29-30 mpg with 32" duratracs ,sliders, roof rack(with deflector). I cant stress enough how much I thank the GDE tune for my additional peace of mind though( with or without the whole delete ). I would honestly be leary of buying a 50K+ mile CRD that wasn't tuned / deleted due to my concern over soot build up and potential long term effects on cylinder heads etc. just my 2 cents and Im not a paid spokes person:) just a happy consumer .

get extended warranty love the jeeps but can be very troublesome.

I do believe so. I have not heard of a single '15 on here that has had to get it's SCR cat replaced. Now that the issue has been elevated to a recall, they have a build date range and it only includes 2014's.

Come to think of it, the elevation to recall is likely in light of the VW debacle. FCA covering their ass as a result of increased diesel emissions scrutiny.

I get a weird surging feeling almost as if the torque converter is slipping but it's not. Happens especially when cold. Also while being it in, I started experiencing the stupid 1-2 down shift bump.

Oh and also bad fuel economy. I'm hoping I get it back and it's even worse lol. I think I'm still going to want a newer jeep with another max care vs keep this one and lifetime warranty.

Re: Ecodiesels with >50K miles - changes in experience

From new until about 44k mine had what most on here call "Fish Bites". Its a quick repetitive shudder while accelerating. It feels like running over the rumble strip on the road's edge at maybe 5 mph. Mine only did it while cold or after a restart and only once. I attributed it to transmission tuning with the latest TCM flash fixing it.

Am I experiencing the head issue instead? I drive it like I stole it to keep carbon buildup at bay and have 64k miles so far.

The only issue I have now is some resonance/rattle at 1500 rpm.

The 60K service is a major one with entire suspension etc. being inspected - does any part of the suspension (especially on the air suspension models) need maintenance or give up at that point?
Just want to address this point the OP made. If you actually read the maintenance schedule the only items that are actually done at 60k are air and cabin filters, oil/filter change, and fuel filters (diesel). (It also adds the rear air suspension springs should be cleaned every oil change?).
These "major" services are typically an excuse for dealers to charge outrageous sums of money for completing all of these items. The reality is most are just inspect items. Your tech may or may not complete these items, in fact in most cases they're going to get pencil whipped. Most dealers will do a multi-point inspection during an oil change anyway.

I completely understand not everyone is a DIY automotive maintainer and not everyone has the facilities for these tasks. I would however caution you about giving the dealer a blank check on these big services. Tell them exactly what you want done and nothing more. But honestly, some of these items are super easy---the air & cabin filters? Pull up a DIY vid on you tube and tackle that job yourself. The dealer will charge upwards of $50-75 to do an air filter when you can do it yourself for less than $20.

Everyone worries about a voided warranty if these services aren't done. For one, it's against the law for them to void an entire warranty outright. Secondly, it's illegal for them to state you have to have the service done at the dealership. You do have to show that the items were completed, but save your receipts for an independent or DIY and you're good.

Agree, don't listen to what the dealer says read and understand what your owners manual says that is what you should follow. Dealers rob people blind by pushing dealer optional maintenance as required. offering it as an option is one thing but stating it is a requirement or your warranty will be voided which many do is fraudulent. The fact is if you are an average driver in average conditions which most are there is very little actual maintenance to perform in the first 100k miles. As mentioned above oil changes, air filters, cabin filters and fuel filters (for the diesel). All very low cost and easy DIY if you should choose. Fuel filters I cant speak for I don't know their cost.

You can always do more if you want but the basic requirements for the first 100k are very few and low cost.
