Electric locks fail to unlock in hot or humid weather. Driver and passengers are also unable to unlock three passenger doors manually, though the key can be used to manually unlock the driver door. This is a safety hazard when passengers are locked in car. The only method to exit at times is to roll down windows and crawl out. In the instance of an emergency where passengers need to exit quickly, this can be a problem.
