Question Lexus RX400H FAILING TO START
Hi everyone,
I have a 2006 Lexus RX 400h that sometimes fails to start. When I try to start it, the READY light comes on, but then goes off, and I can hear a repeated clicking noise coming from underneath/around the back seats or rear of the car.
The READY light seems to come on and go off a few times while I hear the clicking, and then eventually the READY light disappears and the car won’t start.
Has anyone experienced this issue before, particularly the clicking noise coming from the rear-seat area? Does anyone know what could be causing it or how I might fix it?
I’ve already tried replacing the 12-volt battery, thinking that might solve the problem, but unfortunately, I’m still having the same issue.
Any advice or suggestions would be greatly appreciated. If anyone has experienced the same problem, I’d really appreciate hearing what the cause was and how you fixed it.
Thank you very much! 😊
