So do I, but that was not the point now was it? If you are going to insinuate that I am not conveying the truth, then back it up with facts, else we can agree to disagree and move on.
Please answer all three question. Unless you really want one but just can't afford it. The minute I came across this thread I knew you would be here doing what you do without a horse. You ruin forums like this.

Really? I have owned plenty of vehicles that cost more than a Jeep diesel, so give me break, my Rubicon was not the cheapest on the lot. What questions? If discussing reality is ruining a forum, then question becomes what is the purpose of the forum? You can absolutely degrade into insults and character attacks, but it will not change the facts. No need to believe a single word I said, just search Jeep diesel or Ram diesel, it should not take long to see reality.

2020 Rubicon diesel
Here's facts for you. A person doesn't buy a diesel to save money on maintenance or initial cost. A person buys a diesel for what it can do that a gas engine of the same size can't. Can you say "torque" ? Can you say "pulling power"?

I've owned two Ram diesel pickups and have had hundreds of thousands of reliable miles with them. I will probably get a couple hundred thousand more from my current Ram diesel dually too.

I traded a 2018 Jeep Wrangler Rubicon in for a 2020 diesel Rubicon after driving it and realizing the huge increase in torque (climbing capability). The new engine is not yet proven, but time will tell. With all new technology comes a few expected hiccups, but everything will be handled. I am thoroughly enjoying my new Wrangler and love the way it drives and feels. Its additional weight makes the ride amazing, and the added sound insulation is noticeable.

I have 37s on it, get better fuel economy than I did with stock tires and wheels on my 2018 gas, and the weight of the bigger tires isnt even felt, with the torque of the diesel engine.

Nobody said diesels were cheaper. In my opinion, and personal experience, I think the diesel Wrangler option is awesome.

Well said Doug. Range and torque are the reason for a diesel. I’d buy one if they offered it in the 2 door.

It's not the extra cost of the diesel engine over gas base price. It's not whether you have the money to waste or not. $4000 more on a good solid diesel engine is not unusual as diesel engines have always cost $3 to $4K more on most trucks.

The problem is the reliability and maintenance of the new FCA diesel design. More specifically the Italian diesel engine being offered for the Jeep. The design hasn't proven to be reliable. There are many eco-diesel (older gen Ram truck) owners who have warned potential new owners of all the issues.

I was ready to trade in my 2019 for a new diesel JLUR (even if it cost $6K more). I love the diesel sound and torque and really like the way it drove. Unfortunately, after doing a lot of research, I heard too many horror stories on the eco-diesel engine.

For me these are the prime reasons people should look away from diesel:

1- Dealing with the FCA dealers over simple issues is bad enough, let alone having engine related problems.
2- Parts are hard to find and expensive
3- Not many good mechanics available that understand the ins and outs of this engine
4- The design is new and not proven to be reliable
5- The emission system is overly complex and requires too much maintenance (many parts are very hard to reach)
6- The Fiat eco-diesel doesn't have a good reliability record. I've heard of people with their engine lasting only 70K miles before they had to be replaced (just search the internet).
7- You cannot by-pass the emission system. It's not a simple removal of the equipment and involves reprogramming the computer. Most of all, it is not "legal" to do so and you will fail the emission testing when the system is not installed.

I don't mind paying extra to get something better, but I don't want to waste my time on something that I know will require constant maintenance and dealer visits. Those who have lots of cash and time on their hand to waste will not care about these issues and will eventually buy a diesel, but the reason we put our opinions on these forums is to alert other potential buyers that appreciate the information and can make an informed decision.

Mine has been in the shop constantly since 180 miles for EGR related issues. Kinda regretting getting the diesel. Been driving my cummins powered cj7 and do not miss the ecodiesel at all. When it worked great but too many problems, thus far.

Power with my mildly tuned VE pump 4bt is on par with the ecodiesel in my wrangler. Get far better MPG with the 4bt 25/26 mpg vs the 15 or so I was getting (probably related to the multiple EGR issues that plague my ecodiesel wrangler).

I wonder why FCA does not offer a 7 year unlimited mileage warranty on the diesel engines like they do the gasoline models?
Warranties are more than often marketing tools to increase sales when people don't trust a vehicle.
My 08 JKUR came with a life-time powertrain warranty, which was no longer offered after the JK became popular.

driven a 2020 ram 4X4 1500 Crew Cab Laramie eco diesel gen 3 a few times now...NO LAAAAAG AT ALLLLLLLLLL...JUST SAYIN, you might try a test drive to see how they perform
That has been an interesting topic. TFL did videos that showed the horrendous lag. Diesel Power magazine wrote about their experience with the lag in September 2019 and even asked the engineers about it. My personal Gen 3 EcoDiesel lags so bad at times that I literally can count to 4 before the truck will respond to my throttle input. On the other hand, you have some guys online who say there is no lag, and it's perfect. Lol.

So.... I think it's all a matter of perspective and comparison to what you're used to. I'm still getting used to mine, and it's driveable, but I still hate the stock powertrain calibration.

I just came out of a 2019 Corvette Grand Sport and before that a 2015 Hellcat and if there was lag I would notice it. My 3.0 has no lag that I can feel.

Right now local dealer are selling Diesel Wranglers they cant even get for 10 to 20k over sticker. They want a 10k non refundable deposit to order it or find it. If yours is giving you so many problems you should have no issue getting out of it. I know this because one of my employees is trying to get one and that's what he is running into.

Are they all afraid of driving up north a ways? You guys have some no nonsense killer deals over on the east coast.

Getting out of it requires me pawning off the known issues of the vehicle to someone else. That is a problem for me as that is fraud. No sane person would purchase with known problems for MSRP; let alone a premium- as you suggest.

Regardless, I am awaiting on a fix from engineering which will come god knows when. Meanwhile driving my 40 year old jeep.

I did not imply that I think you should screw someone else. Trading it in is not pawning it off, The dealer would then have the time to fix it and then resell it. If you sold it locally or at an auction without saying anything then I would agree with your thoughts. The dealer would not want all the grief of retailing it to one of their customers. I am quite sure it is fixable, my response i was a way you can get out of something you think you don't want to deal with. The next buyer would be no different than all of us that took the risk of the first year run.

Around here no dealer will give you back your money after you drive a vehicle off the lot (I am well past the cooldown period and the issues occurred a few days after the cool down period lapsed). Trading it in would mean I lose a ton of money through no fault of my own. There is no scenario where I can get my money back through a retail transaction.

Currently there is no fix, its under development. I can't get out of it without losing big so I have to wait.
