A warranty claim will be rejected by any provider for pre existing issues. This could be a totally fraudulent claim where cover is purchased because a fault has been discovered. However, it could also be unwittingly. For example a vehicle is recently purchased and a fault is already developing but yet undiscovered. This usually occurs when someone part exchanges a car in because they know there is fault but its intermittent. The car dealer unwittingly sells the vehicle on with this fault and the new owner discovers it once the vehicle is regularly being used.
Excluded or serviceable parts need to be replaced. For example the policy lists Cooling system as covered but pipes/hoses are excluded. These are excluded because they are usually made of rubber, a perishable material.
Neglect: lack of servicing, continuing to drive your car with warning lights on or when its making a strange noise, using incorrect fuel.
Failure to replace parts when required as specified by the manufactures service recommendations, especially timing belts.
Faults caused by external factors such as impact damage or contamination.
