I actually took it in this morning, not sure if the dealership would be able to see the issue. Luckily (or so I thought) I arrived there with the problem showing. I told the person who took the car from me at the service department the issue at hand, and showed him the gray screen while having the car in reverse mode. He checked out the camera in the back and could not find anything wrong with it. Politely he took over the car and said that once they fixed the problem they would give me a call.
4 hours later, I get a call from another service rep, and he proceeds to tell me that he hasn't found an issue with my car, and that therefore what ain't broke won't get fixed. Apparently the camera worked again once the car was restarted. I told him about his colleague seeing the problem I had, but still nothing. He said to return the loaner and pick up my es350 as for they could not do anything about it. My warranty will be up either next April or when I reach 50k miles on it, but want to get this fixed before I have to pay for it myself to get it fixed. Is anybody else being treated as if they've seen ghosts?
Don't have the camera problem, but my dealer would never treat me like that. It's true that they have to have a problem code to bill the warranty part to, but my dealer would simply keep the car in the shop looking for it to fail, or keep a ticket open for 24 hours or so until I get it to fail again an can bring it in. I've had them keep one of my cars in the shop for six days working on an intermittent problem.
Sounds like your going to have to be very assertive....or call Lexus.
