I had very good experiences with Hayward Honda until my last visit. I was told I needed service which was not indicated in my owner's manual. I questioned it and was told I would invalidate my warranty if I did not have the service. When I refused, the service department delayed returning my car although I was waiting for it. A call to the service manager to discuss my experience was unsatisfactory and a note was made on my service records that I was not having suggested work which might invalidate my warranty. I took my car to another dealer who rassured me that the work was not needed.
Be careful with them.
