Toyota trouble  Flex fuel issues
 Buyer beware of flex fuel problems. 2012 In temps of 50 degrees or less it fails to start about every 7-8 fill ups. Requires service each time to fix. No fix yet. Go to the lemon law. Its the Only way to get anything done. To avoid the problem just don't run less than a quarter tank of gas, never run less than 5 minutes, use only flex fuel( if u can find it), move to a warmer climate. Seriously! No joke!$50k truck. 9 months of problems,no help from Toyota. Once you sign your name your stuck on a long rough, frustrating, costly, ride. Thanks Toyota for not standing behind your product. You should stop selling them until you have the problems fixed or at least tell the customer .
