Is Your Car Road-trip Ready?

Half the cars on the road today are more than 10 years old. Once your car hits that double digit mark, it is twice as likely to break down on the road and four times as likely to need a tow. These are among statistics released by the American Automobile Association (AAA). They're the people many call when they get a flat tire or need a battery jump.

"It's no surprise that older vehicles are more likely to encounter a serious breakdown, but it is surprising just how many people are at risk," John Nielsen, AAA's managing director of Automotive Engineering and Repair, said in a press statement.

But aside from helping stranded motorists, AAA also gathers and reports data — it received 32 million calls for roadside assistance in 2017 alone, and about 35 percent of those calls resulted in a tow, for instance. The most common issues? Battery problems, engine failure and tire damage.

So if you're one of the 43.6 million planning a trip by car this summer, it's worthwhile to have your mechanic give your car a once over — and focus on these three areas in particular — especially if you're driving a 2011 model or older.

Dead Batteries

The most common problem AAA deals with is the car battery. That includes issues related to electrical systems, such as starters and alternators. They represented 23 percent of scenarios requiring a tow, according to AAA. And the chances your car will run into these problems only goes up as your car gets older.

But you don't have to become another statistic. Most batteries won't warn you they're on the way out, so inspecting and testing it before you hit the road is your best bet. AAA members can have their batteries and electrical system checked for free to see if it's at full strength or needs replacing. Otherwise, you can have your battery tested by a mechanic or at an auto parts store.

Engine Problems

Engine issues, particularly cooling system failures, were responsible for 11 percent of breakdowns for which AAA was called in 2017. Your car's cooling components, such as the radiator, thermostat, water pump and timing belt can also fail without warning. To be sure your car's engine is in proper working order, check underneath after your car is parked. If you see any fluid gathering on the ground — or you notice the sickly-sweet aroma that indicates a coolant leak — you should definitely get the leak fixed before it causes the cooling system to break down.

Tire Damage

Finally, nobody wants to have a tire blowout while driving on vacation. But tire damage is the third most common reason AAA says it had to send its tow trucks to help out stranded vehicles. To avoid ending up with a flat — or worse — get into the habit of checking your tires on a regular basis, not just before a road trip. You can spot most tire problems long before they leave you stranded.

Look for cuts, abrasions and bulges in your tires, and learn how to check the tread depth and pressure. Finally, know before you leave if your car is equipped with a spare (many aren't these days), and practice changing it. You can't prevent all accidental flats or blowouts, but basic tire maintenance can help you reduce the chance of getting stranded.

The bottom line? Being aware of the risks and knowing what to look for can help you avoid a ruined summer road trip.
