Lexus 450h - engine starts but cuts out

[Hedley John Mayze]

Had big problem with power back door now got to where the car goes to “ready” mode then engine starts but stops after few seconds. Plenty of petrol.Have not driven car more than 200 yards for over 1 year (shielding).12 v Battery replaced 6 months ago and seems fine except for being unable to open back door.

Welcome Hedley.

Sorry to read you are having some problems with your RX. I wonder if they may be lockdown related. If the car is not being driven have you run the engine for an hour once a week as recommended by Lexus? If you have kept the Battery charged by other means you don't need to do this.

Do you have “Home Start” with one of the breakdown companies?  They should have enough diagnostic tackle to at least head you in the right direction or get the car somewhere that does.
