More and more of us are hanging on to our vehicles longer.  A company by the name of HIS Markit recently released a report that shows the average age of light vehicles in the U.S. is now 11.8 years.  Light vehicles are cars, SUVs (sport utility vehicles) and CUVs (compact utility vehicles). 

In Canada, the average life expectancy of a vehicle there is around 13 years, and in the U.S., it’s around 15.  Vehicles are lasting longer these days, and there are several reasons for that.

One expert cites better technology and overall quality improvements.  While in past years, vehicles were made mainly of heavier steel components, more modern vehicles contain lighter magnesium and aluminum alloys, high-strength steel, polymers and carbon fiber.  They last longer and reduce the overall vehicle weight, and that can contribute to better fuel economy.

Modern internal combustion engine designs have been improved, and since they use more computers, they are more efficient with better performance.  Those factors also contribute to a longer-lasting powertrain.  In fact, it’s not unusual to see a powertrain easily last 150,000 miles/250,000 kilometers or more with no major failures.

Drivers are also taking their vehicles in more regularly for periodic maintenance.  Choosing one service facility for all your maintenance can contribute to your vehicle’s longevity, too, since technicians know your vehicle’s repair and service history.

If you bought your vehicle taking out a 5-year loan and you keep it 11 years, you’ve managed 6 of those years without a payment, always a nice feeling.  Plus, a bonus is that you get very familiar with every aspect of that vehicle’s sounds, smells, handling, stopping characteristics, visibility and limitations.  And the more familiar you are with your vehicle, the more confident you can be as a driver.

As the temperatures dip, we all know there could be problems starting our vehicles. After all, batteries can grow old and not hold a charge as well as when they were newer. Or starters can go bad.  But there’s one more component to keep an especially sharp eye on during winter: your alternator.

The alternator is sort of like a small generator. It sends power out to various parts in your vehicle that need electricity.  That includes the battery, which needs charging to keep its power topped off.  The alternator creates electricity by taking mechanical energy from the engine and turning it into electricity.  It is connected to the engine by belts and pulleys. 

In cold weather, the material the belt is made from is less flexible than it is in warm weather.  That means it may not be turning the pulleys as effectively since it doesn’t have the same grip. Also, when it’s colder, lubricants, including the engine oil, are a little stiffer and parts just don’t move like they do when the weather’s warmer.  With that extra strain, sometimes it takes the alternator longer to recharge the battery. That, in turn, may leave the battery a little less power to start the engine when it’s cold.

You may have a warning light on your instrument panel that looks like a battery.  If it lights up or if you notice your headlights flickering or not shining quite as brightly as they usually do, it could mean a weak alternator. But it also could be an aging battery, corroded battery terminals, a loose belt or another charging system part. Yes, it’s complicated. 

Pinpointing the cause involves testing the battery and charging system with diagnostic equipment.  If it does turn out to be an alternator, there are options besides replacing it with a brand new, original equipment part.  Ask your service advisor for recommendations. Obviously, you want your vehicle to start reliably, especially in cold weather.  Take care of your charging system and it will take care of you.
