Regular servicing is recommended every 6 months or 5,000-7,500 miles, depending on your vehicle's make and model. Refer to your owner's manual for specific recommendations.

Common signs include unusual noises (squealing or grinding), dashboard warning lights, decreased fuel efficiency, vibrations, difficulty starting, or strange smells like burning rubber or gas.

An oil change involves draining old oil, replacing the oil filter, and adding fresh oil to keep the engine lubricated and running smoothly.

If you hear squeaking or grinding noises, feel vibrations when braking, or notice a longer stopping distance, your brakes may need attention.

The check engine light can indicate a variety of issues, from something as simple as a loose gas cap to more serious problems like engine misfires or issues with the exhaust system. A diagnostic scan can pinpoint the exact cause.

A diagnostic test uses a scan tool to read the error codes from your car’s computer system. It helps identify specific problems and allows mechanics to pinpoint the issue quickly.

It depends on the issue. If the car is driving normally and there are no other signs of trouble, you might be able to continue driving for a short time. However, it's important to get it checked out soon to prevent further damage.

Tire rotation involves moving each tire to a different position on the vehicle to ensure even wear and prolong the life of the tires.

Possible reasons include low refrigerant, a damaged compressor, or issues with the air conditioning system components. A mechanic can diagnose and repair the issue.

While it's not always necessary to replace all four tires, it’s recommended if they are all worn out. If replacing just two, ensure the new ones are placed on the rear axle for safety.
