We were thrilled with this car when we first got it. A great, comfortable family car for long journeys and a greener option for the city. We knew the fuel economy wasn't going to be great but the fact that you knew you weren't going to be churning out fumes in slow moving traffic was the main winning point. (I walk a lot in town and hate going past slow moving traffic with my kids - it stinks). After a few months the car would not start. And ever since, we've had serious starting issues. New batteries didn't last and the problem persists. Internet searches show many others with the same problem. Lexus shockingly unhelpful.
Comfort, remote boot opening, rear camera.
Obviously, the technology is still new and not entirely understood. Don't risk it yet.
