One problem related to check engine light on has been reported for the 2010 Toyota Prius. The most recently reported issues are listed below.

car   Check Engine Light On problem 1
Failure Date: 11/20/2012

While making a u turn the vehicle lost power and the check hybrid system warning illuminated. The car died in the middle of the road. The dealer claimed that there was oil in the throttle body caused by overfilling and this is a common occurrence with oil overfills on Prius vehicles. The last oil change had been 8,000 miles and more than 2 months previous. The place that performed the oil change agreed to look at car and clean the throttle body. They also checked the oil and made sure it was correct level. Three weeks later the same thing occurred. This time the car lost power and the check engine light illuminated. The car died on a freeway transition over pass and we were stranded on the freeway in a very dangerous situation. The car was towed to another Toyota dealer and they claimed it was the same thing. The oil change place says absolutely no way is this the problem since they looked at it very closely the last time. I requested Toyota to send out a field representative to confirm that this was the cause. They refused. Computer codes p3190 and p0a0f hv.
