A Tesla Model 3 owner was quoted $16,000 by Tesla to replace a damaged battery pack, but a third-party repair shop was able to fix the issue for $700. The problem was caused by road debris damaging the car's cooling system, and the repair involved replacing a molded hose barb with a threaded fitting. The incident highlights the high cost of repairs for Tesla vehicles and the importance of the right to repair. The owner's insurance policy did not cover the damage, and Tesla initially planned to keep the damaged battery pack, but eventually agreed to return it after the owner cited a consumer protection law.
