Starting and electrical supply
Slow cranking, no start, repeated discharge or several warnings can involve battery condition, charging, connections, grounds, current draw, wiring or control. Jump-start history and accessory installations should be disclosed.
Engine and cooling
Rough running, smoke, low power, oil or coolant loss, overheating and unusual sound need operating condition plus relevant air, fuel, ignition, pressure, timing, cooling, wiring or mechanical evidence.
Transmission and driveline
Delayed engagement, harsh shifting, slipping, vibration or noise is recorded by gearbox, temperature, load, selected mode and road speed. A code does not prove internal failure.
Brakes, steering and suspension
Pedal feel, pulling, vibration, heavy steering, knocks and tyre wear are separated. Recent impact, wheel, tyre or alignment work changes the inspection.
AC and thermal load
Weak cabin cooling, low airflow, compressor behavior and engine temperature are observed separately. The issue can be refrigerant, airflow, electrical, control or mechanical.
Body and network electronics
Locks, windows, screens, lights, parking aids and warning clusters depend on stable supply, communicating modules and intact wiring. Non-original equipment is part of the history.
When the engine complaint includes smoke, oil pressure, compression, cooling or internal noise, the engine repair assessment shows what evidence supports deeper work. When the main issue is delayed drive, shift quality, slipping or driveline noise, the transmission repair assessment helps separate control, fluid and mechanical possibilities.
