Sonata brought in for #3 service at 8:30 a.m. Service advisor indicated it would likely take all morning but that she would keep us updated. Never received a call at all. Phoned in and got her answering machine at 12:30.Received a call back at 1:00 and she advised some issues in the back that morning but car should be ready at 2:00. We drove down around 2:20, service advisor not available. We were advised to go in and talk to the cashier .She advised car not ready yet but did have the invoice. Car finally ready at 2:45 .Lengthy time frame to do the servicing, no update,no response to email forwarded on your website..AND if the service advisor had told us the cabin filter needed replacement we could have had that done at the same time .
