Does the Tata Intra V30's sudden acceleration problem make it a deal breaker?

Reports of Tata Intra V30 have sudden unintended acceleration, where the vehicle runs when the driver does not want. This has started to raise concerns of owners and potential buyers of the vehicle about safety and reliability. It might be a software glitch that can be fixed with an update, or it could be a more serious mechanical problem, some say. The question is whether it's a one off or a wider problem and how Tata Motors is dealing with customer complaints. It also raises concerns about how commercial vehicles in India are tested and controlled.
