How to Fix the 12 Most Common Car Problems Yourself

4.Battery Failure

Most car batteries are designed to last around three years or 50,000 miles. A dead battery is often caused by reduced electrical current, which happens as the battery ages and loses its charge-holding capacity. Issues like a faulty alternator or damaged charging components can speed up the process. For optimal performance, replace your battery every 50,000 miles or three years, even if you don’t notice any immediate problems.
