    Yesterday my wife's 2013 Prius V hybrid system warning light and airbag light came on immediately after hitting a pothole. The same two lights came on about two months ago. At the time my wife mentioned that she thinks she may have hit a pothole. So now I'm really thinking the pothole could be the cause. When this occurred two months ago, I took the car to a local Toyota dealer (Leith Toyota) but they couldn't find the problem. The lights were off when I left the dealer. I can't remember if the dealer turned off the lights or if the lights turned off by them self. Anybody have an idea as to what may be causing this problem? Thanks.

    Its helpful to know what symptoms occurred in addition to the lights. Did it stall? Did it lose power? Etc. Probably a bad connection somewhere is dropping out a circuit or two. If the trouble lights are on there should be trouble codes to read which might focus the search. Do not clear the codes with a reader or disconnect the 12v battery to cause the codes to clear before someone with the right tool can scan the system. Even then, sometimes it takes a real diagnostic expert that can follow schematics and is knowledgeable enough to probe and isolate systems in order to find an occasional problem which may not still be active. There are a few ace troubleshooting techs but they may not be at your dealer or the tech you got may have quickly looked and cleared the codes thinking it was an one time random event. Again, the trouble codes are a big clue and sometimes a visual inspection by the right guy leads to a solution.

    No symptoms. The car continues to drive normally. And everything sounds normal. She just hit a pothole, the car beeped and the hybrid system warning light and airbag light came on simultaneously.

    Intermittents are the most difficult to diagnose.

    More than likely the problem will be back.

    We had an intermittent VSC and a couple of other random indicators that I traced to road salt/water intrusion into a wheel speed sensor connector. Cleaned up, dielectric lubed, and reinstalled, it hasn’t made a squawk since.
