Recently we had issues every once in a while where our edge didn't want to start, always had us worried since it is the push start, not like you can hold it down to "crank", but eventually it would start. Then yesterday the check engine light came on. Checked code ourselves and got bad #5. Took it to the dealer and they said the same thing and will replace since under warranty. We are at 40,000 miles. But now they are trying to tell us we need to get our tranny flushed and suggested fuel injectors cleaned as well. Manual says tranny doesn't need done until 150,000 miles and should we need injectors cleaned at 40,000? We do not tow and live in the midwest. Thanks.
