careful sounds like a rod knock--bring it in before you see a $5000,00 problem

Should i make a video for you guys to id the sound? Its very very low and unnoticeable unless its dead quiet out. Curious why the manual says a knock is normal. It only occurs while accelerating

2.4 liter knocking noise below 10 mph

It does not sound like rod knock as it is sporadically loud from what ive seen. Its like a very low hum and only occurs upon pressing gas to accelerate

The low pitch knock is consistent with the manual but theres a loud noise upon takeoff or low mph. I will take a video to show to yall. Appreciate the help.

Specified oil changes, yes

Topping off oil, one time in the winter it went below fill line during warm read at tip of dipstick. Immediate oil change the following day as low oil came on during a turn.

Always used full synthethic 0w-20
For two and a half years you've heard this knocking?
You have had all the specified services?
You have 5000 miles left on your Warranty?


The Dealer has suggested a Carbon Clean? Because of knocking?
But Carbon does not explain two and a half years of knocking!
Is the knocking getting worse?


BUT nobody else thinks the knocking is a problem?
Do you think the Dealer is waiting for the Warranty to end?

Perhaps some members in Canada may be able to help?

Could it be an engine mount?

2.4 liter knocking noise below 10 mph

The low pitch knock is consistent with the manual heres the two videos as promised one parking going back and forth and driving. If in at an angle theres a loud song but im assuming it may be the old driveshaft and a combo with my afternarket tires and rims (running a 17 wheel i believe?)

https://youtu.be/CJ8_Je4uefQ

https://youtu.be/TRNaKiNIHGM

The noise in particular is clearer in the parked situation. Me driving forward then reverse (the clunk is me switching gears)

I don't hear anything concerning.
