Sorry for the rant but I am beyond frustrated. This is the 4th service appointment without repair of a simple issue. I have had wind noise from my front right window since I received the vehicle 3 years ago. Mobile service did not have any parts to repair the window seals on first visit and recommend repair at a service center. After visiting a service center the window gaskets were replaced but said that I needed my fixed window replaced. They didn’t have the part in stock but said they would document what was needed and would have mobile service scheduled for repair. On the second mobile appointment they did not have the part and failed to read the service notes before the scheduled visit. They said they ordered the part and rescheduled another visit. Well just prior to the next visit the appointment was rescheduled because the part has arrived. On the next scheduled appointment the technician again arrived without the part or no knowledge of prior service calls. They have waste my time and still haven’t completed the repair in close to 3 years. Furthermore I can’t get anyone on the phone to discuss this. Is the sys broken?
