We had a "hybrid system malfunction" warning on the dashboard and the van slowed down to 20 mph on a climb. With the flow of traffic at 50mph on a two lane road and no shoulder to pull off, this cause a serious risk to us and other drivers. Stopping and starting the car several times did not cause the warning to go away and the owner's manual says to stop driving. There were no warning lights prior to this happening. The warning and the MIL came on at the same time as the van started slowing. The local dealer now has the van and are not able to exactly diagnose the problem. They are contacting the manufacturer. They said the warning is no longer on.
