Hello Everyone I have a 2014 Toyota Corolla S Premium, it has 7,400 miles it is 9 months old (since I bought it) and I have just started hearing almost a week now a whisle sound while driving my car it only happens when I press on the gas pedal (accelerate) and when I brake and stop. The whisle sound goes away when I stop pressing on the gas and when I have come to a complete stop but I hear it while I am stopping and accelerating. I can only hear the noise if I have my radio completely off and the windows are rolled down, if I have my windows up or my radio on I can no longer hear it. I am wondering if this is normal? Isn't my car still relatively new to have parts needed to be changed already? I appreciate any help, comments or advice. Thank you.
