Purchased our 2018 JL Unlimited Rubicon about a week ago. We have experienced rain every single day since then, so our Jeep has yet to have its top or freedom panels off. The Jeep handles well, brakes well, accelerates fairly well for a V6 of this weight, and the ride is smoother than expected. Cabin noise is more noticeable in the Rubicon (than the Sahara trim level) due to the tires and additional height, but it is not bad. The interior is attractive, comfortable, and the laid out well. Too early to comment on the gas mileage, but the Jeep is approximating the posted values by the manufacturer thus far. Reliability and repair frequency Is not applicable at this stage. We did purchase the 10 year, bumper to bumper extended warranty as a precaution based on poor experiences with a GM product years ago.
So, let me say this - the new JL Wrangler has improved a lot over the outgoing (but still offered for sale, for some reason) JK Wrangler. My biggest complaint is the build quality. Our Wrangler Unlimited Sahara showed up with one Freedom top panel a different color. No biggie, probably a Friday job car. But the battle to get it fixed with the local Jeep dealer in Medford OR was epic. Initially the dealer was confused as to why we would want all the top panels to match... Then when tasked with fixing it, they said "drop it off and we will send it to the body shop to get it painted" So we'd get a loaner for "3-4 weeks" Um, no... After several calls to FCA corporate, the dealer agreed to get a new panel and have it painted, and swap it out. After owning the Wrangler for a few weeks, we noticed little things wrong. Like the sunvisor was split open with the plastic guts sticking out. Not what you'd expect from a $50k car. The new 8-speed transmission flat out sucks. It is shifting constantly, even on flat ground. When towing it really never stops shifting. After calling the dealer service department, their response is pretty much "if it moves, and no warning lights are on, there's nothing we can do about it" - - Be warned, FCA will do "over the air" updates on the car. Gone are the days of the dealer forcing software updates on the vehicle when you drop it off for an oil change. After leaving the dealer, the (very expensive) 8.4" Uconnect screen had "Off Road" pages to show fun things like approach angle, oil temp, etc... The next day after getting the Wrangler home, POOF! They were gone, like they were never even there. FCA says it will be a feature on the 2019 Wrangler... LOL ; so how did they appear on a 2018 Wrangler then disappear? I will always wonder what Jeep might have evolved into had Daimler Mercedes retained ownership (a G-class equivalent !?) rather than Fiat taking over and doing what Fiat does best... Make no mistake, the Wrangler JL Unlimited is a fun car, and it is still a Jeep. And there are so many improvements over the JK. It just feels you should get something that "feels" more quality for $50 grand, rather than something that feels slapped together with a lousy transmission and the same boring old Pentastar V6 that FCA has put in just about every vehicle built for the last 10 years (who needs direct injection or turbochargers when a gas guzzler V6 still sells?)
So far with with only 350 miles on my new JL i think this is the best wrangler to come out in years, but time will tell. My only complaint so far is the slight wind noise coming from the hard top panels.
