| Warning light or reduced power |
Stored faults, electrical supply, relevant live data, and physical checks |
Arrange diagnosis. Stop if there is severe shaking, smoke, overheating, or another serious warning. |
| Coolant loss or rising temperature |
Leaks, coolant circulation, airflow, and temperature control |
Stop safely if overheating occurs. Never open the cooling system while hot. |
| Rough idle, vibration, or a new engine noise |
Ignition, fuel delivery, mounts, leaks, and mechanical condition as appropriate |
Book an inspection. Avoid heavy acceleration until the cause is understood. |
| Harsh shifts or delayed engagement |
Fluid condition, leaks, controls, mounts, and drivetrain operation |
Arrange testing. Do not keep forcing engagement if drive is unreliable. |
| Brake vibration, pulling, or grinding |
Pads, discs, calipers, wheels, tires, and related suspension |
Seek inspection promptly. Stop if braking control is affected. |
| Slow starting or repeated battery discharge |
Battery health, charging, connections, and abnormal electrical drain |
Request a starting-system check instead of assuming a new battery will solve it. |
