NOT unless it was stolen. Stolen cars are reported stolen. Cars securing a loan in DEFAULT are reported as DELINQUENT to the credit bureau. If you choose to report the car stolen, go ahead. I would not reccommend it though. Filing a false police report is illegal in most jurisdictions.
In the UK, over 90,000 cars are reported stolen each year. However, this number has been decreasing steadily in recent years due to advances in security measures such as immobilizers and tracking systems. It's always recommended to take precautions to reduce the risk of car theft, such as parking in well-lit areas and using steering wheel locks.
Over 1,000 cars are stolen in a year.
