2.0L Engine Knock at 16,400 Miles

[JP28]

Definitely loud. Mine doesn't sound like that and I have almost 60k miles. If it's only when cold try a different or better oil. What kind of oil do you run? The 2.0 is a noisy engine. DI gives it that diesel sound. Mine has a rattle on cold start but doesn't knock like that and goes away pretty quickly.

For the no start... Try using the fob to push the start button. If the battery is dead/bad in the internal chip will still register when held against the button.

For the no start, try pushing the start button with one of the corners of the FOB. Some cars when the battery in the FOB gets low, you have to use the fob to push the button so the antenna is right next to it.
Sounds silly but it’s in the owners manuals of many vehicles.

It was worth a try. Thank you.

Much louder and nastier than my 2.0.

Poor jeep is unhappy. What's with all the bolt on stuff? Anything done to engine like a BOV or something that can be causing this?

Bolt on stuff? And no, everything is factory with the exception of a teraflex adjustable steering stabilizer. Pretty sure thats got nothing to do with any of this.

Maybe you're referring to my off road lighting mounted in front of the windshield. All of that is basic positive and negative DC connections wired up to the factory aux switches.

I meant in the picture/video you have dash covers, knob covers, pedal covers, etc, etc. It is clear you like to modify. Nothing wrong with that - jeeps are made to be made our own. But was asking as I know a popular mod is to mess with the bypass valve on the 2.0 to make it make turbo whoosh noises and that can lead to turbo flutter and with the waste gate linkage prone to rattling the two combined might sound like what you're experiencing. My 2.0 sounds a bit like a singer sewing machine when just started if it's cold out.

Oh yeah, no, I have no interest in turbo flutter or anything else reguarding waste gates or blow off valves. Those day are long gone. I put all that speed and cool sound stuff away when I sold my 2016 370Z to get the Jeep. I've reached the age where I just want to cruise. That said it's not easy to cruise around here. We've got a real problem with people constantly tailgating you and trying to push you down the road. I mean it's bad.

At this point I'm wishing I'd stayed with JDM. 🫤

Mine is bone-stock too, oil changed to spec, not abused. It sounds the exact same way.

Wish I would have stayed with GM. (Ok, NOT a 6.2 truck motor)

While researching my knocking issue, I discovered this video that I found very interesting. Maybe others will as well.

Mine sounds identical - which now has me worried

I'm approaching the 5 year/100k KM extended warranty and have it booked in for an oil change next week - I'm going to ask them to have a listen/look at the knock and will update with their response.

I knew this was a noisy engine so just assumed the knock was normal but we'll see. I do love the pickup and gas mileage - but if it's dying already then wow

Run her till she comes apart..

Over the years, I have had a few cars, new and used. I have had Ford, Chevy, Nissan, and Mitsubishi. So, in September of 2022, I decided to join the Jeep community and order a 2023 Jeep Wrangler, JLU Willys. It also happened to be the first time I have ordered a vehicle from the factory. My Jeep ended up arriving in November 2022. I was very excited to take delivery and experience what it is like to own and drive a Jeep Wrangler. It was a blast for the first 10,000 miles. Unfortunately my 2.0L turbo engine developed a very loud knocking/ticking sound every time it started and was driven after sitting for a while. This knocking was not present when I took delivery. Recently, I test drove a 2025 Jeep Wrangler, equipped with the same engine. It did not come close to sounding anything like what my engine sounds like now.

Since the knocking started around the 10,000 mile mark, I have taken the Jeep to two different dealerships, multiple times each, to have it diagnosed. First it was "everything sounds normal," and then it was "we are going to replace the timing chain tensioner. " After that, I was told the knocking sound was gone. Did I mention, that at 14,000 miles, it left me stranded at a stop light when the engine just died and would not restart? It turned out I had a failed/defective EGR valve. Anyway, it has now been 6,400 miles since the knocking began, and I have another appointment on Friday to have it investigated again. My question to the Jeep community is, does anyone think a 2023 Jeep Wrangler, that costs about $58,000 and has only 16,400 miles on it, should sound like what is in the video below?

Personally, I think some loose change being shaken in an empty soda can sounds better then my engine. What exactly is Jeep's policy on customer satisfaction? Help! Any advice or information would be greatly appreciated. I will update this after the Friday appointment.

UPDATE: Well, We didn't make it to Fridays appointment. Got up and went to McDonalds around 6am, came home and ate breakfast. Went to go back out around 8:30am ish and................

JEEP, There's Only One..... and its broken. This sucks.

Any updates?

Update:
After multiple times in 2 different dealerships waiting an average of 1 week per visit, providing video/audio evidence of the engine knock in question, both service departments just lied to my face multiple times saying "we were unable to recreate the noise, everything sounds normal." So, I decided to call it quits and traded it in on a fully loaded nissan frontier pro4x. Good luck to all who have invested too much money (imo) and their trust in jeep or any other brand that is controlled by Stellantis. I will never trust them again nor any jeep dealership in my area here in northern Virginia. After they get your signature, without a code, your on your own. Unless you want to pay out of pocket of course.
