Symptoms of Auto Problems

Your vehicle might be having issues in various different components related to its electrical, steering, suspension, brake, and combustion systems; and there can be many culprits behind these problems. If you want to understand better what your vehicle’s problems are, search this symptoms list for an issue that’s similar to yours.

Check Engine Light

Cause: This warning light can be triggered by a wide range of issues, such as faulty sensors, a loose gas cap, or engine misfires.

Strange Noises (Squealing, Grinding, Knocking)

Cause: Squealing may indicate worn belts, grinding can signal brake issues, and knocking noises often point to engine problems like a damaged rod or low oil levels.

Unusual Smells (Burning, Gas, Sweet)

Cause: A burning smell may indicate overheated components or leaking oil; a gas smell could signify a fuel leak, while a sweet odor might suggest coolant leaks.

Poor Fuel Efficiency

Cause: Clogged air filters, malfunctioning oxygen sensors, or dirty fuel injectors can increase fuel consumption.

Excessive Exhaust Smoke (Black, Blue, or White)

Cause: Black smoke may indicate a rich fuel mixture, blue smoke suggests oil burning, and white smoke could mean a coolant leak.

Shaking or Vibrations While Driving

Cause: Unbalanced tires, warped brake rotors, or worn suspension components can cause vibrations, especially at higher speeds.

Car Stalls or Hesitates

Cause: A failing fuel pump, dirty throttle body, or faulty spark plugs can disrupt engine power, causing stalls or hesitation.

Overheating

Cause: A failing radiator, low coolant levels, or a malfunctioning thermostat can cause the engine to overheat, risking severe damage.

Fluid Leaks (Oil, Coolant, Transmission Fluid)

Cause: Damaged gaskets, seals, or hoses can result in visible fluid pooling under the vehicle.

Uneven or Rapid Tire Wear

Cause: Misaligned wheels, underinflated tires, or worn suspension parts can cause uneven tread wear, reducing tire life and safety.
