The 4 banger is the bomb. It sounds like an Electrolux vacuum cleaner but it has the acceleration of a Hellcat.

The 2 door with the Turbo 2.0 is so damn zippy, you’ll sell your ‘vette because it feels like a tank…….

Hey everyone. Those who have the 4cyl turbo and have had the V6 pentastar do you regret the 4banger? I want a AT cuz dealing with crazy city traffic ,but I can’t have the V6 in sport. Only option is 4banger or V6 in rubi too rich for my blood. Real world pros and cons from actual 4cyl owners what would yr advice be? I’ve had 4 Jeeps with pentastar and know what issues I have to deal with at certain points of the engines life. Etc…
I know a lot of people first time jeep owners love the 4cyl just confused any help would be great thanks
I have the 2.0T and do not think I would buy it again. Performance is fine but the engine sound is terrible. So bad you want to cringe when you drive slowly with the top down. It just whines… you can do a search and see the complaints. Again, performs great but the sound is so bad that I would most likely go with the 3.6 if I could do it again. Just my personal preference.

I chose the 3.6 Pentastar only because of the so-called carbon issues the direct inject engines have. I had a Subaru 2.0 direct injection that suffered from carbon issues. I suspect if you are going to keep the 2.0 for over 100,000 miles, dealing with carbon on the valves will be inevitable.

45k miles on my '21 JLUR and I love the 2.0T. It's taken me to Deadhorse, AK; Homer, AK; offroading in Death Valley; Utah x3; Telluride, Ouray and many other parts of CO on multiple trips. Performs well not he interstate, especially the long grades in the mountains. Performs great at low speed of road. Instant cold starts in winter (many sub-zero MN mornings and one -35F in WY last winter). Doesn't miss a beat when running at 75 mph in +100 F in the summer. Flawless performance all around. Sounds like a farm tool at idle but runs perfectly every time I get in it. If I wanted a Jeep for the way it sounded, I'd buy a 392.

I've had the 3.6 in other Jeep products and hated the way it had to rev and downshift to make any torque. Never had any issues with the 3.6 reliability but but the driving performance could only be described as adequate.

Lol. I DO NOT understand what makes the 2.0 sound like it does. When it starts, it sounds like a 4-cylinder, normal. Put it in gear and apply throttle to take off, and it sounds like a Power Wheels electric jeep at low RPM, kind of screechy and whiny. When ON the throttle and cruising or driving spiritedly, it sounds like a peppy 4-cylinder should.

A lot has changed with regard to gas direct injection systems in the last 10-15 years. Early DI designs back then had well-documented issues. Ford's Ecoboost and GM's 3.6 have been in service for a long time now, same with GM's Direct Inject 5.3 V8. With new head designs and software updates, it's not the issue it once was.

Thanks good info from an actual owner. I would rather have the 3.6 but I’m not spending 4500 for an auto in a rubi and the MT is on restricted until Gid knows when some people been waiting 5 months and it’s not even built go figure 🤷‍♂️ appreciate yr help

There are still issues with direct injection. Ford changed their design from direct injection to both direct injection and port injection (combo) due to carbon issues with the 2.7 and 3.5 ecoboosts. Subaru is still doing walnut blasting services on higher mileage engines. BMW is still reporting carbon issues on DI. I would love to hear from some high mileage Jeep 2.0 owners. The carbon issues seem to become apparent around 100,000 miles and up.

It's a combination of direct injection and the dual balance shafts. Lots and lots of mechanical noise from it all.

The exhaust sounds fine, it's just the engine itself is a damn tractor.

You can't order the i4 2.0 now, anyway - not on Wills, Sahara or Rubicon - I was about to put in an order for a Rubicon X with the i4 2.0 - but that config is not available - plenty early 2024 Rubicon's shipped with the i4 - but no more :(
