2.0T knocking noise

[Rtant]

We have a 2019 Wrangler JLU with 2.0T and for the past year we have experienced a hard knocking noise from the engine. We have taken the JLU to several dealers, a couple dealers said the noise was normal, other told me there is an issue but they can not pinpoint the problem. They also said there is really nothing they can do unless a check engine light or code comes up. Has anyone else experienced this issue with the 2.0T?

Thank you in advance for your help

I have a 2020 JLK 2.0 and I'm not sure I have the noise you have but during a cold start, the Jeep sounds like it is missing/backfiring for a couple of minutes. Once engine warms up, it's really smooth. It's done this since new and has almost 5000 miles on it now.

I just listened to the attachment. I don't have that noise. That doesn't sound right.

Try a different dealer - that sounds really bad.....is the dealer deaf....

I have a 21 2.0T and do not have that noise. That’s horrid.

I heard it once too, only on cold starts but I remote start most of the time, so by the time I get to my JL, it’s already gone (if it still makes that noise)

put your foot 2 the floor with the motor running when it blows call the dealer 2 pick it up

This is one of 20+ video clips I have of the Jeep. Once I played it in the dealer and the mechanic said “ that sounds normal, all Cummins sound like that” . Fun thing, they still have not fixed the problem.

Thank you for sharing your clip, unfortunately our noise doesn’t go away once the engine is warm. The engine doesn’t constantly make this noise but it is daily.

My 2020 JLU Willy's 2.0L was very noisy like that when it was cold, and produced a lot of steam out of the exhaust for the first few minutes after start up, then went away after about 2 minutes and was fairly quiet. On my 2021 JLU Rubicon with the 2.0L, its much much quieter, with significantly less steam coming from the exhaust, even when started cold and after 2-3 minutes, the engine is very quiet. I already traded in the 2020 Willy's for the 2021 Rubicon, but I'm wondering if the 2020 had an issue (even though what I read on forums, it was normal), since the 2021 is so much more quiet and smooth. My 2020 sounded like a diesel until it was warmed up.

Find another 2.0T on the lot and ask them to start it and see if it sounds the same.

Ours sounds the same. Just had it at 2 different dealerships and was told it was normal. Sounds like this on every cold start.

Not that I trust these dealerships because they both said they couldn't do the steering box TSB due to my lift even though the Jeep still has 100% factory steering components!!!

Just a thought...

Could you be running regular gas? If memory serves, the 2.0 is supposed to run on premium.
