We were driving our new truck (only 13 days old) and came up behind a car going 25mph in a 50mph zone. We slowly accelerated the truck to pass the vehicle. During this acceleration, we saw large amounts of white smoke coming from both tailpipes. Then a brief single chime started from the instrument panel. Because it was a new truck we didn't know what was happening and there was no safe place to pull over. We continued up the road and the chiming increased in frequency and white smoke began to come into the cab and from under the hood. We came to side road and immediately pulled over. We got out and the white smoke continued to bellow from under hood. After truck was turned off, the smoke slowly subsided. We towed the truck back to the dealer on a flatbed.
