Our 2005 Prius failed to start fan and airconditioning when started. The icons were all gray and the engine kept turning off more quickly than usual. After reving the engine and restarting the car 3 times everything seems to be normal. Should we be concerned and have it checked out?

The previous solution to check the idle air contol is in the correct area but needs some clarification.
The idle control is accomplished by two parts: Throttle position sensor ( $35 at Autozone) and idle contol valve approx $190. I replaced the throttle position sensor about a week ago and it runs perfect
to date but am a skeptic after almost two years of dealer incompetance. I researched all the sensors and failure symptoms on the internet and the throttle position sensor failure symptoms matched mine
exactly. See http://wiki.seloc.org/a/Throttle _Position_Sensor

SOURCE: 2005 equinox the intermittant power steering issue

The power steering is on this vehicle is electronically assisted. Meaning it does not have a power steering pump. The electric motor could be going out, pulling too much current at times, and tripping the breaker. The best thing to do is take it to the dealer, and have them inspect it.

most of the newer cars especially the new chevys are all ran off the bcm or body control module, i would have someone with a snap-on brand tester check to bcm and the parts of your car first to make sure what is all wrong, could just be a shorted wire or a broken vacuum hose

I have same problem with 2002 laguna. Before warning lights and revving at 2000rpm starts car feels jumpy. Have to stop, take card out of slot and back again to start without fault. Happens a few miles drive later again. Anyone got a solution?

SOURCE: 2003 Cuts off when hot, will not start untill cool

My 2003 nissan sentra would get hot and stall out even in middle of highway doing 70 mph. The guages would go up and down. Would not start up all the time after stalling. had to cool down first. Nissan said it was head gasket, and wanted to charge 1000.00 for the job. I took to local dealer who charged me 550.00. Works fine ever since. Nissan dealer said they do like 3 head gaskets a week on the sentras. They have crappy ones in original parts. They have not recalled though.
