My CHR car suddenly malfunctioned and I had flashing messages appearing on the dashboard - hybrid system malfunction etc. The power steering stopped working and the brakes also were very sluggish. I had to call the RAC who towed the car back. Called the Toyota garage who replaced the battery but the problem persisted. The garage took it back and they now say they could find any problems but I have now lost the confidence in driving the car as I don't want this happening when I am on a motorway.
