- Note when it happens (cold start, turning, braking).
- Check dashboard lights—photograph any codes.
- Look for leaks under the car (clear, brown, green, red).
- Open the hood: inspect belts, fluid levels, and battery clamps.

Quick guides
Check‑engine light just came on
Tighten the fuel cap first. If the light persists, pull the code with an OBD2 scanner and search the exact code description. Many auto‑parts stores scan for free.
Clicking noise when turning
Often a worn CV joint. Inspect the axle boots for tears and grease splatter inside the wheel. Avoid sharp turns until inspected.
Battery dies overnight
Look for interior lights left on, corroded terminals, or parasitic draw. Clean terminals and have the battery load‑tested.
