An average of 13,000 Americans are killed between Memorial Day weekend and Labor Day, some as a result of unperformed vehicle maintenance, according to the National Highway Traffic Safety Administration. Each year, neglected maintenance leads to more than 2,600 deaths, nearly 100,000 disabling injuries and more than $2 billion in lost wages, medical expenses and property damage.
Most mechanical failures can be traced to neglected maintenance. For example, the U.S. Department of Transportation reports the leading cause of mechanical breakdown on our nation's highways is overheating, a condition that is easily avoidable. Other deficiencies that are simple to detect include low antifreeze/coolant, worn or loose drive belts and defective cooling system hoses.
Checking tire pressure and inflating a tire costs nothing, yet an average of 21 percent of cars inspected in check lanes during National Car Care Month have under inflated tires. This can lead to a blowout and a serious accident.

The Car Care Council offers these fuel-saving tips:
Car Care Council offers three suggestions for a traveler's 10-minute pre-trip checklist:
"While a last minute checkup is better than no checkup, motorists should plan ahead to allow time to perform necessary maintenance themselves or at the local service facility. A properly maintained vehicle is safer and more dependable and will even save a few dollars at the gas pumps," said the Car Care Council's Executive Director, Rich White.
Not only can a pre-trip inspection help reduce chances of costly and possibly dangerous road trouble, it also provides an opportunity to have repairs made at home, with one's own technician who knows the vehicle. Especially important, it provides peace of mind. While no inspection can guarantee a car's performance, it's comforting to know proper precautions were taken.
