Engine knock when idle


Topic starter

Hello all:

I have a 2021 GX460 with 1UR-FE engine. I notice when car is idle and there is a knocking noise from the engine. I don’t know if it’s normal. Car has 1500 miles.

It sounds like”tick, tick, tick, tick” not very obvious but enough for me to hear it. I heard it inside of my car.

From my own older car, I found out there was slack in the timing chain. Have them check it out if yours does have a chain, it could be that there is a bit of slack making the fast ticking noise.

1500 Miles? When the dealer tells you, "They all do that." ask them to start up another GX460 so you can listen to it.


Agree with @Glen_stet. Keep taking it to the dealer and force them to fix it. That GX460 should not be making a ticking noise. If that dealer can't fix it, take it to another one. Also, if you know a trusted mechanic, have him/her check out the GX and give you some kind of report in writing. Then, take that with you to the dealer and show them.
