Gen6 HELP!!! My car makes a weird noise when I start it. w/ VIDEO!!!



Can someone please help me out. I video taped my car being started. This has been going on for awhile now. Sometimes the noise would be longer and louder or very short like this one. It only makes a noise if you start it in warm to hot weather. What is this noise from? Thank you!

almost would seem to sound like the starter gear is not retracting from the flywheel once you release the key..??

weather should not have much to do with this, but i would like to hear the noise a bit longer, as i have had to replay what you provided several times

i would get it up on jack stands, get underneath it, have someone start it up for you. or, you could just open the hood, locate the starter, and put your hand on it, then have someone start it for you..feel for any vibrations

i am thinking it might be flywheel/flex-plate as well.......

Once i release the key, the noise comes up. Well the weather is a weird thing because when i start it in San Francisco, where the weather is cooler and fog, the noise does not come on at all. no matter how many times i start it. In San Jose, where it's warmer right now, it makes this noise.

yes, as you know we need to use the key to start it, and when we release it, it's supposed to cut off the circuit to the starter. so i am wondering/thinking if after you release the key, the starter drive is still engaged into the flywheel...

maybe due to the warmer temps, there is expansion of the metal parts, that cause this.

there is the checks i told you about. you could even take out the starter and take it to auto zone, pep boys and have them bench test it. i do not believe you told us the year and miles on your car either.

My car is Camry 2007 LE V6 with 74300 miles. I also have the 7 year/100,000 miles powertrain warranty also. So i might just go the the dealer and ask if it's covered.

I still have it under my platinum/premium 7 year/ 100,000 mile warranty. Brought it to to the dealership and showed the master tech the video. He said it sounds like the timing (something) that deals with the oil going into the camshaft. It like 14 hours job and the whole engine needs to be taken out. If that "is" what he thinks but he is not sure. My car is still in the shop.
