So I have a 2011 WRX hatch and recently I have had this awful squeaking/squealing noise coming from the engine bay when I drive. I have linked a sound clip video of it. For the first 5 mins of driving it doesn’t happen, then it starts happening randomly at any time sometimes worse and sometimes not as bad. Over bumps it seems to get louder and as I give gas it gets louder. I’ve checked all suspension parts and they are fine. I think it’s a pulley gone bad but I’m not sure. Please help!
