New thread with Big update.

2005 4Runner V8 with 105k.

Background:
About a week ago or so, I started up my truck in the morning and immediately heard a loud ( Shop Vac sounding) buzzing type noise from under the hood that I had never heard before on any vehicle. I froze in confusion trying to listen for what the hell it was. By the time I opened my door to get out and look under neath the noise stopped and everything was fine. Normal idle, no check engine light. Nothing. So I drove cautiously and everything was fine. Through out that day I turned off and started my truck up multiple times with the noise never showing its face again.

Day 2: First start in the morning and the same thing happens. Same noise.
I immediately pop the hood and find the noise coming from lower passenger side of the block. but still cannot pinpoint exact location.

Day 3: Post on here and some facebook groups. with help from fellow members and experienced people. I find this: Nothing happens the rest of the day on any other start up except the first.

WHAT YOU NEED TO DO IF YOU EXPERIENCE THIS PROBLEM:

I went to my local Toyota dealer to discuss the matter only to leave frustrated because they had no idea what I was saying. I don't understand why you put people in service departments that don't know anything about how a car works.

on the way out a mechanic who overheard me gave me THIS NUMBER:

Toyota Customer assistance : 1-800-331-4331 <--- If you have a v8 Call IT and tell them you have this problem!

The Customer Service rep acknowledged that Tundra's and Sequoia's with the V8 have the exact same defective part as us. And on those vehicles Toyota was willing to extend the warranty to 150k and either repair or reimburse previously repaired trucks.

She went on to explain that they do have quite a few documented cases but not enough to make Toyota take the next step and extend the warranty on 4runners to Replace or reimburse for work done on this part.

In short: If you have a V8 Call- Call even if its not broken YET, for you in the future and Call for all your fellow 4 runner friends with V8's who need every single one to be a documented case to get this fixed. Its over 3 grand out of pocket if its not covered.

If you pay or have paid to have it fixed. KEEP ALL RECEIPTS.
If you paid, had it fixed and don't own it anymore but can prove you paid to fix it. and they extend the warranty they WILL reimburse you.

*If you didnt fix it yet, call, call and call some more. If they extend warranty, the total cost of approx 3 grand will be covered by toyota.

Phone number is- 1800-332-4331
Tell them you heard it from Reference number # 140-722-0993
