I purchased a new RX400H last September and in general have been very pleased with my purchase.
Shortly after purchase however, I had a fault appear in the display on the dashboard which said 'check Hybrid system' and 'check VSC system', along with all the warning lights. The RAC (Lexus Assist warranty scheme) came out to check the fault and accessed the above fault code P3016 and were able to cancel the fault. Howver, the fault recurred on my way back that evening and the car was taken to the Lexus dealers who I understand changed out a sensor in a cell of one of the batteries.
The fault recurred a few times after that -between September and November - but each time either the RAC cancelled it and it stayed off, or it appeared and subsequently disappeared without any intervention. The car appeared to drive perfectly normally, even with the fault code up; perhaps because of this the service section at the dealership did not appear to consider it prejudicial or a safety hazard for me to continue to drive the car.
From November until last week, the fault never recurred. However, last week the fault re-appeared while driving on the motorway and quite scarily, shortly after that the vehicle lost power and cut out.
The RAC came out and once again were able to cancel the fault and the car appeared to be driveable. However, I had it recovered to the dealers who have had it for a week and have not been able to repeat the problem. They say they have never encountered the particular fault code, previously.
I'd be interested to know from anyone who has had this fault come up and the solution if you or your service company found a solution to the problem.
Thanking you in advance for your time in responding.
