Most Reliable Engine for 2025, 2.0T or 3.6?

[3TV]

If someone were thinking of getting a 2-door Rubicon X with 4.88 gears to leave almost stock for tooling around in the back country by themselves in their retirement years, which engine would be the most reliable?

Asking for a friend.

3.6, the one that’s been in over 10 million vehicles.

having had 5 wranglers rubicons with 3.6's including my current 2024 jlur I would get a 2.0 simply because I have a buddy that has one and I have driven it and we go to moab together and other offroading and his flat leaves me for dead on the highway and gets better mpg even tho he has 37's and i only have 35's

17 year Jeep tech here, this is a easy answer 3.6 is the one you want.

2.0 turbo. Much better power, fuel economy and overall performance. Especially if you live at or visit high altitude.

Neither.

If reliability is high on your list, you shouldn't be looking at a Jeep. If you must have a Jeep, drive both engines and pick the one you like the most. Reliability is mediocre in both cases, overall power is very close. Really the difference is in manners, and how the power is delivered...so it comes down to what you like best.

...had 3.6, now have 2.0T. Live and play at 7K+ vert. Both 4.10 with 35"s... 3.6 was needing a re-gear to make it up steeper hills, 2.0T makes it up the hill no problem. 2.0T gets about +3.5 mpg over 3.6. 2.0T sounds like an angry vitamix trying to puree a frozen banana

Between the two - especially if you are going with 4:88 gearing - 3.6L all the way. Drove a number of 2.0's and although not quite as "peppy" the 3.6L is smoother with a much more predictable powerband. Sounds better too.

Had both.I like the 2.0t better.It does sound funny when you first start it up.Best to test drive both and see what you think.

Most reliable is a TJ with a 4.0. The 3.6 and 2.0 aren't very good engines on the reliability side.

Saying jeeps are unreliable is a total lie have you looked at the legendary brand Toyota my family has had Toyota since the 1980s we have also had many American cars in the family 80s Toyotas were total junk whereas teo of our K 10 trucks went over 500,000 miles. My 2007 Tacoma wouldn’t go in four-wheel-drive half the time. Our 2012 Camry needed an engine and transmission under warranty my 2014 4runner had a leaking timing cover from the start.

Every brand has issues but a stock wrangler treated right is pretty reliable and easy to repair. The engine options aren’t perfect but the 3.6 has been fixed to where it’s probably not getting better.

The 2.0 turbo is a very clumsy engine if you live at altitude due to the turbo lag. The higher the altitude the greater the lag.

I live at 6,000 ft elevation, and often go exploring at 10,000 ft. I agree, turbo lag is an issue
