Our CRV makes a buzzing noise, much like an old doorbell, in the rear-end panel on the driver's side. It occurs every time you accelerate after coming to a full stop. The noise will pulse for a second or two and then stop. Any ideas, my mechanic is stumped.

 

Record it for us.

 

Thank you for the response but it is too late now, my mechanic found and fixed the issue. The rear door lock activator was malfunctioning and needed to be replaced.

 

welcome to the forum. thank you for the follow up as to the cause.
