In automobile maintenance, the engine is typically the component with the highest repair cost after damage, accounting for approximately 15% of the vehicle's total price. As the core structure responsible for the vehicle's safety, the chassis accounts for 20% of the vehicle's value and incurs high repair costs, though its actual likelihood of damage is low. The repair costs for the drivetrain (e.g., transmission) and electronic control systems (e.g., ECU) are also substantial, representing 10% and 15% of the vehicle's total value respectively-especially for carbon fibre drivetrain components or advanced driver-assistance modules in luxury vehicles. Notably, customized interiors (such as carbon fibre seats) or exterior body panels (like carbon fibre front splitters) in premium models may carry individual price tags exceeding 50,000 Malaysian Ringgit, though such damage primarily occurs during accidents or modification scenarios. Overall, engines emerge as the most expensive maintenance item due to their frequent replacement needs and technical complexity, whereas chassis and electronic systems demonstrate higher costs during complete assembly replacements.
