* Check Engine Light (CEL): This is the most common light. It indicates a problem detected by the car's onboard diagnostic system (OBD-II). You *must* get the code read. An auto parts store often offers free code reading services. The code will give a clue about the issue (e.g., faulty oxygen sensor, loose gas cap, etc.).
* Other Warning Lights: Besides the CEL, there are other lights, such as:
* Battery Light: Indicates a problem with the charging system (alternator, battery, or connections).
* Brake Light: Could be a low brake fluid level, worn brake pads, or a problem with the brake system itself.
* Oil Pressure Light: A very serious issue indicating low oil pressure. Stop driving immediately if this light comes on.
* ABS Light: Indicates a problem with the Anti-lock Braking System.
* Airbag Light: Indicates a potential problem with the airbag system.
* Possible Causes (depending on which light is on):
* Faulty Sensor: Even with low mileage, sensors can fail. Oxygen sensors, mass airflow sensors, and other sensors are common culprits.
* Electrical Problem: A loose connection, corroded wire, or other electrical issue could trigger a light.
* Low Fluids: Low brake fluid, oil, coolant, or power steering fluid can trigger warnings.
* Wiring harness issues: Although rare, a rodent could have chewed on some wires.
* Malfunctioning Component: A component could be failing even with low mileage, although this is less likely.
What you should do:
1. Identify the light: Note exactly which light is illuminated.
2. Check the owner's manual: Your owner's manual will explain what each light means.
3. Get the code read (if CEL): This is crucial for diagnosing the problem.
4. Check fluids: Inspect the levels of engine oil, coolant, brake fluid, and power steering fluid.
5. Have it inspected by a mechanic: If you're unsure about the cause, a qualified mechanic is the best resource. Given the low mileage, there's a possibility something unusual is happening, and a professional diagnosis is needed.
Ignoring a warning light is never a good idea. Addressing the issue promptly can prevent more significant problems down the line.
