When I unplug the 3 wire alternator plug the noise stops. When i plug it back in, the noise starts immediately for 1/2 a second, then stops for 3 to 5 seconds before starting again.  once noise starts it does not stop. The alternator usually starts making this noise after engine warms up for 10 to 15 minutes. Once in a while the noise starts after 2 minutes from a dead cold start. Just today for the 1st time it ran for 37 minutes with NO noise, then i shut her down for 2 minutes and restarted the engine, then after 45 seconds the noise started. 2 different screwdrivers touching front, mid section and rear of the alternator, with other end in my ear and I hear nothing. Same with short hose touching or just very near alt.   I cant reverse spin the Alt coupler pulley clutch\decoupler, as shown in this video. See https://youtu.be/1Duj1jh1rlA  Mine behaved like his. If this is even a proper test for a toyota. My noise does sound like The Drake alt coupler pulley clutch\decoupler here: See https://au.toyotaownersclub.com/forums/topic/39853-issue-with-squeal-coming-from-engine-area/   Although mine also sounds like this alt rear bearing noise here: https://www.youtube.com/watch?v=dTNM5X7ufk4 Separate issue: Turning accessory pulleys/tensioner/idlers by hand with belt off and hot engine I hear no noise, see no wobble and feel no oddities. Pulling/pushing them in and out, laterally back and forth(rocking), and laterally side to side I feel some play. Some more then others. pwr steer pump moves in and out a lot. tensioner same but less and also side to side. wtr pump moves in and out, but less so and rocks back and forth. AC comp moves in all 3 directions, but not by a lot. Upper idler rocks back and forth more so. Lower idler rocks back and forth just a little. I don't know how much is acceptable/normal or if I should be concerned about some of these. The Alt I could feel no play.

FYI, I’ve looked at UTube videos of Toyota Master technicians. They all say NEVER to overfill the gas tank as it can do harm to the hybrid system. They say fill to the first click and stop. I’m sure that if enough Venza owners complain, Toyota in time, will be forced to recall, just like the RAV 4 hybrids.

camry noise.mp3 I recorded the sound my 2004 camry xle makes, it is only 8 sec long, maybe someone can help me.  PLEASE!!!!!!

Just purchased my first Toyota, 2021 Highlander Premier, which came with Goodyear Eagle tires as original equipment. As a former Goodyear employee I was glad to finally see Goodyear on a new vehicle, my last three had Michelin, Continental and Pirelli in that order. After working for 25 years at Goodyear, mostly in sales, I am very familiar with the Eagle tire line which is known for great handling but not so much for tread life. What concern's me are the reviews I have read which gave low marks for handling as well as tread life. Just curious if any other Highlander owners that have Goodyear tires have any comments about the tires on their vehicle.
