Toyota Rav4 grinding noise

Hello, I have quite the dilemma with my 2009 Rav4. I have taken it to 3 different mechanics (1 was a shop mechanic, 1 was the mechanic at the dealer, and 1 was my Dad who is a retired mechanic). Anytime I am driving between 30-45ish miles per hour my car randomly makes this grinding noise when I accelerate. It immediately stops when I take my foot off the pedal and seems to happen more often on hills, corners, and when the car has been running/driving for awhile. The shop mechanic couldn’t pinpoint it, the dealership said it is the transmission however couldn’t be more specific, and my Dad thinks it is the heat shield (which he has tried adjusting many times and the noise keeps coming back). Anyone have any experience with this? It is driving me nuts and doesn’t sound very safe…

If the noise stops when the heat shield is adjusted ( there is no adjustment for heat shield ) just find a muffler shop and have the shield fixed properly.

You may have to pay for a shop to actually find the problem if it is not the shield and your vehicle should be taken to an independent shop not a dealer at 9 years old.

I’d give your Dad a pass as he’s retired but surprising neither of the two shops would use these to locate the source of the noise- https://www.amazon.com/Steelman-97202-Wireless-ChassisEAR-Diagnostic/dp/B00123J79O

Very surprising the dealership would come to that conclusion but offer no basis for it. Did you pay them for a diagnostic?

Hey TwinTurbo, thanks for the advice, yeah he doesn’t have a shop anymore just his garage but I will send him this link maybe he know a good shop with on. I am also surprised neither the shop nor the dealership used that device…and of course I paid for diagnostic (I know I am a sucker haha)!!!

Hey Volvo_V70, The noise doesn’t stop, it got a bit quieter and then got louder over a few weeks back up to how it was. I think he jimmied something (and said “adjust”) but I have already tried at the local shop (and told them I thought it was the heat shield)…they weren’t helpful.
