That sucks. Hope they find the trouble.
Too bad about your other truck.
I had bought a new '88 Dodge for the wife and the second day of ownership it drops dead in rush hour traffic. Ignition crapped out.
Had a boss that had bought a new Dodge truck (1976??) with a 318 engine in it. Two weeks after he bought it, while driving past the dealer, the engine decides to toss a rod. He coasted into the lot trailing an oil slick. They pulled an engine from a new truck on the lot to replace it.
