While traveling to Ohio I found the need for my Lexus to be serviced. Calling Metro on a Thursday morning I was only able to get the first available appointment for the following Tuesday. I extended my trip and brought my cat in to the Metro service department on Tuesday morning. I left detailed information regarding my problem with my navigation system. Steve was my service consultant. He said that he would try to at least get it diagnosed by Tuesday evening. I did not receive a call back until 10:59 am on Wednesday along with an email estimate. At this time the service department knew the parts needed to complete my repair. I understand that they did not want to order them but they could have checked to see if they are in stock which they did not. Because I need clairifucation I contacted Steve immediately by phone I did not hear back for three hours while my car sat in the service feoartment. When Steve did get in touch with me he didn't have the answer and had to check with service technician who was at lunch. When I finally got my answer it was 3 pm and then was told not only would it take 3-4 days to get the navigation system and it could not be sent overnight. In addition to that part they did not have the air filter or sensor parts in stock. Excluding the navigation repair it would take an additional two days to get my car partially fixed. I told Steve I could not extend my trip any longer and I would pick up the car in the morning. When u arrived to pick up my cat Steve did not have the paperwork ready and I had to wait an additional 20 minutes. When u asked to speak to the service manager I was told he was in a meeting all day and could not be reach. Over all the worst serve I have ever received from Lexus. Very disappointed. Metro Lexus needs to take a lesson in service from #Discount Tire who only asks after helping you that you refer a friend who needs tires.
