Tire pressure was the number one vehicle issue identified during the most recent nationwide clinics conducted by AAA and its affiliated repair facilities. Results are based on inspections conducted on 6,082 vehicles by 25 different AAA clubs. Automotive solutions source NAPA has partnered with AAA to offer answers to some of the most common vehicle challenges. During the AAA events, inspectors discovered the following: • A clogged air filter was the second most common issue. NAPA says that maintaining and replacing air filters as often as recommended in the owner’s manual will ensure better air flow through the engine. This, in turn, will improve engine efficiency and result in more power and better fuel mileage. • Insufficient tire tread depth was the third most common problem. For sufficient traction, tires should have a minimum of 3/32” tread depth NAPA recommends using a depth gauge or a penny to measure your tire’s tread depth. Most tires also have built-in tread wear indicators that let the driver know when tire replacement is necessary. • Engine oil that was low or needed changing was the fourth most common situation. Dirty oil will increase engine wear, while low oil levels can lead to overheating. If the oil level drops too low, lubrication will be lost and severe engine damage can result. Regular oil changes will add longevity to the engine. • The fifth most troublesome item was worn-out windshield wiper blades. Rigid, cracked or torn wiper blades can greatly reduce visibility when driving in rain and snow. NAPA recommends examining and replacing wiper blades once a year or sooner if streaking begins.
