Driver mode
For drivers
Describe what you notice, include the vehicle year, make, model and engine when known, and share any OBD-II code. CarDiag24 explains terminology and suggests next checks in everyday language. If the vehicle may be unsafe, stop and seek professional help.
Safety comes first
If the oil-pressure or brake warning is on, the engine is overheating, the warning light is flashing, or you notice smoke, fuel smell, loss of steering or braking, stop in a safe place and seek professional or roadside help. Do not rely on AI to decide whether a vehicle is safe to drive.
