Made an appointment about 4 weeks in advance to get my ES serviced due to fuel pump recall. I explicitly wrote down my reason for the visit while setting up the appointment. But when I visited the service center and after couple hours of wait I was told they don't have parts in their inventory and need to order them. They told me I'll be notified when they receive the part but it's been already over 3 weeks and no call.
Purchased 3 cars from this dealership but extremely disappointed. My next Lexus purchase and service will be from another dealer.

EDIT: So I was told by my friends that the dealership's management/owner has changed. If true, kinda explains why their overall service quality went down.
