Thank you for your visitor message. Iím very sorry to hear that you are experiencing this sound with your Regal. I can certainly imagine your frustrations with this, especially after multiple dealership visits. Are you able to provide a description of the sound that you are hearing? Also, were you by chance able to have a technician ride along with you at the dealership? I would be happy to get in touch with your dealership for any additional insight and check on a few resources on my end. Would you mind sending me an email at [email protected]? Please be sure to include your VIN, mileage, full contact info, and the name of your involved dealer. Hope to hear from you soon.
