Was Driving down a fairly busy street today, and all of the sudden my Check Battery Light comes on, I lost steering and brakes(They were so hard to control took my entire weight on the brakes to stop it) I had to drive the car approx 1.5 miles to get a place to safely pull over, by the time I do, I am getting massive steam from the engine. Open the hood and its a broke serpentine belt, the damn thing is just shredded. My question is, will running a new engine like this (less than 400 miles) for approx 1.5 miles at 30-40 mph have any adverse affects on my engine? The car is under warrenty and I want any possible problem resulting from this to be fixed properly. Any input would be great.
