I would like to know if anyone else has an intermittent whining noise in the engine compartment of their 2014 Tundra or Sequoia? It sort of sounds like the high pitch air noise a diesel truck engine makes when revving up.
It is coming from the engine compartment on the passenger side.
I hear it all quit often at different speeds but generally on acceleration at all speeds.
My guess is that it is some sort of air intake.
