If the car won't start, check the battery connections and charge if necessary. Inspect the fuses related to the ignition system. If the problem persists, it may require professional diagnostic service to check the starter motor and ignition switch.
To improve fuel efficiency, ensure regular maintenance such as oil changes, air filter replacements, and tire pressure checks. Drive smoothly, avoid excessive idling, and use cruise control on highways when possible.
Common causes of brake noise include worn brake pads, debris between the pad and rotor, or warped rotors. Regular inspection and maintenance of the brake system can help alleviate these issues.
