Hey all,
Have a 2022 JT with the 3.0 Ecodiesel and around 45k miles.

Can anyone tell me if the sound it's making while priming (2 presses of the start button) is normal?!
Video here:


Everything is in perfect working order, but there's an RPM-dependent whining noise that the dealer has not been able to identify and fix (2 pulleys and a whole 8HP75 transmission have been replaced, without addressing/correcting the issue). I used a stethoscope and found the whining noise is loudest around the HPFP cover.

After I turn off the engine, it makes a BUZZing sound in the same area (around HPFP) for around 1 minute 20 seconds. Normal also!??!

Z96 recall appears as COMPLETED for my Vehicle VIN. Have had no way of confirming if in fact this was done.

Mine makes that high pitch priming sound only after changing the fuel filter. Sound after shut off engine is normal. Should have a recalled performed sticker attached under the hood and fuel door.

The buzzing after shut down is normal. It lasts for a few minutes. It's a relay for the fuel pump.
