#4484 of 9498 V6 Engine Ticking Sound?
Feb 02, 2002 (8:51 pm)
I recently purchased a 2002 Highlander with a 3.0 litre V6 and there is what sounds like a tick, tick, tick sound when idling. Apparently,this is pretty common with the Highlander's and has had much discussion on Edmund's Highlander Forum. My service dealer told me that the sound is coming from the fuel injectors, and it's common to Toyota’s V6 engines. I believe the Lexus RX 300 has the same 1 MZ-FE V6 engine has the Highlander, has anyone noticed the same ticking sound and if so, what was Lexus response?

I have been having the exact same problem with our '00 RX since it was new. It has been back to the dealer numerous times and had the following repairs, all under warranty but the noise is still there. Worse when the temperature is below 45. Only audible when idling in Drive or Reverse. Noise is much less when in Neutral.
I have had a complete new exhaust system and new engine mounts but the noise is still there. I have asked my service manager to check with Lexus to see if other owners have reported similar problem. If this is on the NHTSA site, there must be a manufacturing problem.
Please keep posting if you find a fix because I am getting desperate. Thanks.

Wife has 2001 and loves it. No problems at all with 22k on odom.
I am trying to locate the AC filter she said should be replaced.
If anyone has replaced AC filter I would appreciate some insight.

The filter is located behind the glovebox and a couple of easily removable panels must be "popped" out before you can replace the filter.
Open the glove box and located a small rectangular panel to the back of the glove box. Gently pull that off.
Take a flash light and you'll see behind that is the panel to the filter. There should be a couple of tabs that you can grab and tug out the panel. The filter can then be pulled out. There should be directional arrow to show which the the filter should be positioned but if not just remember the orientation of the filter. Put in the new filter and reverse the procedure for the panels and that's it.
#4488 of 9498 Rmorin2: Engine booming

Years ago, the Porsche 924 had a similiar problem. Chuck Stoddard, the mechanical genius who owns Stoddard Imported Cars in Willoughby, OH, could sometimes fix the problem by loosening the engine and transmission mount bolts, drive the car around the block, and then re-tighten the bolts. I don't know if the same fix will work on your RX. Good luck!

Bingo! You were right on target. Found it and it was filthy. Many thanks!!

Sounds like we have the same experience - the booming does seem to be more acute in colder temperatures and only occurs when idling with the transmission in DRIVE; no problems when actually driving.
Did you show your technicians the NHSTA message? Did they install an exhaust damper to help curb the noise/resonance? Unfortunately my problem is not vibration but rather an intermittent booming noise and as such, "difficult to replicate" when I take it to the dealer. I've even tried different grades of fuel, but that has not helped either.

#4493 of 9498 Pinging?
Feb 04, 2002 (1:37 pm)
Recently I've been hearing pinging noises when accelerating. It occurs either on level or inclined surfaces. This is the first I've heard the pings and I'm attributing it to some possibly bad gas. I've put about 3/4 new premium fuel but still seem to hear the pinging. What's my next step?
