• Damage sustained due to road accidents or negligent handling.
• Corrosion, malfunctions, or defects caused by exposure to industrial emissions, chemical pollutants, acid or alkaline environments, plant sap, animal waste, de-icing chemicals, or adverse weather conditions such as hail or lightning.
• Failures in fuel system or exhaust components attributable to the use of substandard or contaminated fuel, including leaded gasoline.
• Improper or careless repair attempts that result in physical or technical damage, rendering the component defective and unserviceable.
