If I purchased a vehicle that had a mechanical failure with in 24 hours and I returned it, am I bound to the contract?
Question Details: Can I get out of the contract based on mechanical failure within a 24 hour period?
The way to answer your question is whether or not the vehicle you purchased was a brand new vehicle, a used vehicle, or a vehicle under warranty. If under warranty then there is a possibility that the mechanical failure is covered. If no warranty, then you may have a problem on your hands.
The only way that you can cancel your purchase contract regarding the car you purchased is if the seller knew there was a mechanical issue with it before you bought it material to the price paid or desirability by a willing buyer and failed to disclose such to you. Proving such is ordinarily difficult from a factual standpoint.
