    I have a 2013 CRV version and my car started making a high pitched woo-woo-woo sound on a cold start, upon accelerating a little bit (placing the tranny to drive and barely or not stepping accelerate). It's usually gone after driving for 15mins. This started after I drove under strong rain and wet road with some puddles, but not flooded. What could be the cause?

    What you are hearing is probably one of the belts slipping.

    Most likely the pulleys are affected. Aircon, tensioner, engine pulley.

    Try this for troubleshooting. With a cold engine, start the engine, spray some water onto one of the belts and see if the noise dissipates temporarily.

    fanbelt araa, like the tensioner, lever arm tensioner shock or bearing's--- of your alternator, compressor.

    it could also be your brake or brake disc..

    rust accumulated overnight on your brake disc...

    I don't think it's fan belt as the noise starts only when the car starts to move. There's no noise if the car is stationary even after starting the engine.

    Ni-research ko wheel bearing and sabi the faster the car accelerates the louder yung noise ng wheel bearing. Since nawawala yung noise after a few minutes hindi ata wheel bearing.

    Nasa isip ko lang kasi baka kulang na lubrication kaya paguminit na, nawawala. I might be wrong din.

    It's best to let it be checked sa casa since under warranty pa yung oto.
