Approximately 7 months ago my 2007 Toyota Prius began accelerating during use of the cruise control. I reported the problem to the dealership who said they have no fix for it. I can't use the cruise control in my car for fear the car will not stop accelerating.

The flexible gas tank on the Prius often fails to fill up all of the way to full. In cold weather the tank often fills only 8 gallons(when completely empty) and sometimes clicks off at 3 gallons or less and keeps clicking off until more gas is forced into the tank. The Prius was brought in to the dealer and they looked into the tank issue and found nothing. There recommendation was to fill up on the slowest level and to tilt the gas nozzle to side or upside down to force more gas into the tank. This did not rectify the situation and the dealer could not offer any further remedy. The dealer will not do anything further to fix the situation.
