Insurance companies call for cause and origin investigations and expert opinion reports for various reasons. These reasons can include: whether the engine failure actually happen as alleged, whether the cause of the engine failure was due to a failure to properly service, and/or maintain the vehicle, or plant and equipment, whether the engine failure was a result of poor maintenance by either the insured, or an external servicing repair facility, whether the cause of the engine failure was due to a manufacturing fault, or whether the engine failure the result of an incendiary event?
These are questions that can only be answered by careful forensic examination of the vehicle, or item of plant and equipment by a suitably trained and qualified professional.
