Hi Everyone,
I have a '21 JLUR 2.0 that, while it's always been noisy, has started to make some more noticeable and alarrming sounds over the last month. Specifically, when cold especially and then even when warm during acceleration, from about 1800-2200RPM there is a very pronounced metallic rattle. Anyway, finally took it into the dealer this week after my wife finally asked what that awful sound was!
The tech was able to reproduce the sound. That's the good news. Now, they are probing me to see if I used the wrong oil and are making me jump through some hoops to essentially prove that I didn't. FYI, I used Pennzoil Platinum 5w30. I shared with then the language from the Pennzoil site showing that it is SP and GF-6 certified, as well as the language from the owner's manual saying this is exactly what to use.
I was able to pry out of them that the tech believes the sound is emanating from the top of the engine. He also noted that initial thought is it's valvetrain-related. No mention of the turbo.
Anyway, that's where things are. Hopefully they accept that I used the right oil (because I did). I get why they are asking, which is fine though.
Will provide updates. Hope this is a short thread!
