 I have had nothing but problems. Sure better not trust it on a trip. I have sat in a hotel room one week and looked at the wall while the car was in the shop. Navagation gave out on another trip . Plans were made for a trip this week  but this time I  never got out of town. All lights were on. I was in the service dept instead of leaving.This has been going on from the day I brought it home. Almost 2007 and only less than 35,000 miles. I am solving this problem.Talking to Lexus. Plans in the making for a 2007 LS 460 so I can travel again. I have driven nothing but a Mercedes and was a die hard lover of the car.
