2006 Prius, 141k miles. Started car to drive home from work and it had a chugging noise. () Drives fine When I'm outside the car with the hood up there's no noise coming from the engine bay No error lights or codes Sounds like its coming from something in the console, not in the engine bay?
it does. Also no noise from the engine compartment at any point. I posted this elsewhere and someone suggested it may be related to climate control motor getting stuck - and after cycling through the fan speed options and temp options and air circulation options it has resolved!
