I took my car in today to get an oil change and they advised that I needed to do the inverter recall as well. I picked up my car and drove all of 1/8 of a mile before the Check Engine Light came on. The car would only run on battery power. I pulled over and the battery level was very low and the gas motor was not kicking on to charge it. When I put the car in Park the master warning came on. I restarted the car again and in park the ICE showed it was charging the battery but the CEL was still on. I drove it back to the dealer on just battery and I am waiting to see what the problem is. Does anyone have any thoughts on this?
Probably an oil over-fill, or other malfeasance whilst checking for a dirty air filter. It could be a problem with the inverter pump recall work, but that usually takes several miles of running to trigger a code.
They said the car is good to go know. They are saying the cause of the issue was excessive carbon build up in the throttle body. Not sure if I quite believe that.
I suggest you update your profile so we know what kind of Prius you own. The Classic Prius was very susceptible to engine no-start due to excessive black gunk in the throttle body interior. 2G is less so, but if your car has a high odometer reading then it is possible that the throttle body needed to be cleaned.
