My RX400h was running perfectly. I checked the oil etc.and filled it to the brim anticipating a 600 mile trip. It ran for 7 miles and petered out. A.A.could start it but it wouldn't run. A.A. said 'it seems to be flooding'. Lifted it to my local reliable garage (over 30 years) where it has been for 8 weeks.They are totally confused.

 

"Flooding"? Are you saying that the Hybrid Battery has gotten wet? That is a 400 type problem and it will stop the car from running. You'll need to dry it our if it is the case and then seal the ingress areas.
