About 2 months ago, our 2006
About 2 months ago, our 2006 Prius began to display the master warning light and a couple of the others. The problem seems to occur upon acceleration and never in the middle of a normal drive. The lights seem to clear themselves a few hours later and the car continues to run. Took it to a dealer twice...paid some money...but, still have the problem...with no solid idea what the problem might be. Sounds like the problem Michele (above) is having. In my mind, the problem occurs upon acceleration...just as the vehicle "shifts" from the "battery mode" to power by the gasoline engine. Does anyone here have any ideas to solve this problem??
