While it has great performance, the dealership and the Lexus extended warranty are worthless. Rattles that I say exist are either can't be duplicated or if found, not covered under warranty (have to pay for diagnostics.) Complained about a rattle when starting the car but dealership could not duplicate. This year voila! - the rattle is a recall item which we received no notification but discovered when getting serviced at the dealer. Reliability- if they can't find it its not a problem - until the warranty runs out.
Engine, gas mileage and the heated/cooled seats.
Navigation system is useless and unintuitive - my 2001 Acura had a better interface. Better service from dealership.
