As mainstream as Tesla has become, its repair process is still far more drawn out than what you'd expect from a conventional. It's not unheard-of for owners to wait weeks or even months for a working vehicle after a crash. That's about to change, according to Elon Musk. Tesla now plans to conduct most collision-related repairs "in-house" instead of farming them out to third parties, which often have to order parts and often aren't very familiar with Tesla's lineup. There are already some repairs that finish within 24 hours, Musk added, with plans for same-day and even one-hour repairs.
