How Far We’ve Come (Newer Vehicle Technology)

Automotive design has come a long way since the days of the Model T, especially when it comes to safety technology.  You can thank computers for a lot of the latest innovations.  Here are a few that have been making their mark in recent years.

Adaptive cruise control.  This is cruise control with a brain.  Not only will adaptive cruise control keep your vehicle going at a steady speed, it will also slow it down and even stop it if the vehicle ahead of you slows down and stops. 

Automatic emergency braking.  We’ve all been distracted while driving, and you’ve probably been in a situation where the driver ahead of you has suddenly stopped.  Or maybe your attention wandered for a minute and you looked up to see your vehicle closing in fast on the car ahead of you.  (After all, there are a lot more distractions in your vehicle these days.)  New systems that use cameras, lasers and other types of sensors will warn you to start braking.  If you don’t heed the warning, they’ll put on the brakes for you. 

Blind spot warning.  We all worry about hitting a car approaching from behind and on either side if we are changing lanes.  Rearview mirrors cover some blind spots but they’re not foolproof.  Enter the blind spot warning system; it warns you with a noise or a light if a vehicle is in a spot you might not be able to see.

Lane departure warning.  We all try to stay in our lane, but sometimes our attention wanders.  If you start to drift out of your lane, new warning systems using cameras and other sophisticated sensors will tell you to get back in your lane.  Some send an audible warning, others use a vibration or warning light. Some will even steer your vehicle back into the lane. 

Rearview camera.  There was a time when trucks and SUVs were involved in horrible accidents because the drivers couldn’t see what was behind them as they backed up.  Children and pets were among the tragic victims.  Now, inexpensive rearview cameras are required in the U.S. and Canada, saving lives and providing much more peace of mind for drivers of vehicles with rear visibility issues. 

It’s important to make sure this safety technology is working correctly for these systems to be effective.  Your service facility can check and maintain these systems as the manufacturer recommends.

Busted! Air Conditioning (Air Conditioning Maintenance)

Your vehicle’s air conditioning is something you count on when the weather heats up.  But there’s bound to be a day when you turn it on and one of these things happens:

  • Only warm air blows out
  • Cold air starts blowing out but then it turns warm on its own
  • It’s not blowing air at all
  • It blows smelly air out

Some people are tempted to try to make the diagnosis—and the repair—on their own.  They think it’s just run out of refrigerant and they can pick up a can at a local auto parts store and re-charge it.   If only it was that easy.

A vehicle’s air conditioning system is complex and made up of many parts.  A compressor, evaporator, condenser, tubing, hoses, sensors, valves… the list goes on and on.

Each of these components could be the reason for the problem.  It could be a leak that’s letting the refrigerant escape, but simply re-charging the system hasn’t fixed the problem. You have to find the source of the leak and fix it. Service facilities have a device called a “sniffer” which can sniff out refrigerant chemicals. And they can use black light to locate refrigerant that has an ultraviolet dye in it. 

But often other components wear out; blower motors go bad, resistors blow, tubes clog, compressors fail. And diagnosing that takes training and special equipment you’ll find at your service facility.

One other thing to keep in mind.  It’s always better to catch any problems in the air conditioning system before it fails. Ask your service advisor about having

the A/C checked as part of the vehicle’s maintenance.  That’s the cool way to go.

Some New Boots (Suspension Maintenance)

There are some boots that don’t come in a shoe box and aren’t worn on your feet.  They are called axle or CV boots, and they can be important parts for many vehicles.

That CV stands for constant velocity.  CV axles are mainly used in front-wheel drive and all-wheel drive vehicles. They’re also used in some rear-wheel drive vehicles with independent suspensions.  They have two CV joints, one inner and one outer, placed between the axle and the drive wheels.  That way the vehicle’s engine power can drive the wheels, no matter what angle they are.  They also adjust for the different speeds wheels turn as they go around corners. 

Because roads are full of all sorts of hazards (dirt, oil, water, grime), these CV joints need to be protected.  They also have grease in them to keep the bearings moving smoothly.  That’s the job of the rubber boots that are supposed to keep that debris out.  These CV or axle boots are made of rubber or plastic and usually last a long time without any problem.  But sometimes they fail, either from being hit by debris or age causing the rubber or plastic to deteriorate.  That can allow the grease to leak out of the joint and the moisture to get in.  And that’s where the trouble is.

So it’s important to have a vehicle’s CV boots checked periodically, especially when they begin to have more than 100,000 miles/160,000 kilometers on them.  A technician inspects them for tears or cracks.  Sometimes if the problems are found early enough, the boots can be replaced and the joints can be re-packed with grease. 

But sometimes the CV joint can wear out even though the boot is intact.  When the CV joint fails, you might hear a grinding, humming or clicking noise and feel vibration.

Some of these can be difficult to access for service, so many service advisors will recommend replacing the joints and boots at the same time.  Just remember, new CV boots won’t make a fashion statement, but they will keep your vehicle going down the road for years to come.

Not So Cool (Air Conditioning Systems)

There’s nothing quite like getting in your vehicle on a hot day, switching on the air conditioning and having warm air blow out of the vents.  You may have had no problem for months and then, one day, you are driving around in a sauna. You’re hot stuff, but not in a good way!

So what goes wrong when the AC isn’t working? It could be a lot of things because the system has many different components.  One thing that’s a common cause is the vehicle is low on refrigerant (it used to be called Freon).  If that’s the case, it’s not as simple as simply adding more.  Sure, it may fix it quickly for a short time, but it’s more likely than not that the refrigerant will just leak out again.

The original Freon used in air conditioners was destroying the Earth’s ozone layer, so that’s not used much any more.  But the one that’s currently used also contributes to global warming, so it’s important that as little of that escapes as possible.  So a technician will determine if there’s a leak in your system, where it is and fix that before adding new refrigerant. 

Your vehicle also has an evaporator or two, and those can fail.  Leaks are often the problem with them as well.  The big component that can go bad is the compressor, often a victim of age, wear or neglect. 

A technician will also check to see that the blower is working correctly.  That’s what blows that cool air into the cabin.  Sometimes the motor will fail, a relay will go bad or a fuse will blow.  As you can see, there are lots of different parts involved here! 

The good news is that your vehicle’s service facility has the special equipment to recover the refrigerant and check the system’s pressure, both vital to properly servicing the air conditioning system.

As with many vehicle components, regular maintenance can go a long way to minimizing problems in the air conditioning system. It can reduce the chance of the compressor having to be replaced, too.  Pretty cool, huh?

Light’s Out! Trouble Ahead (Exterior Light Bulb Service)

Whether or not your exterior light bulbs are all working probably is not at the top of your list when you think about your vehicle.  But those exterior lights are more important than you think, and they’re vital to your safety and that of other drivers near you.

Headlights are important.  Not only do they help you see safely down the road at night, they also help oncoming drivers know that the vehicle they’re approaching is not a motorcycle.  Both headlights should be working properly and aimed so that they don’t blind other drivers.

Taillights are also important for a few reasons.  They tell drivers what your intentions are (changing lanes, turning, stopping).  So, the bulbs back there must be all in working order for maximum safety. Ditto for the front turn signal lights.  They alert oncoming drivers to your lane changes or turns (if you use your turn signals!).  Some side mirrors also have turn signal bulbs in them.

There are a few other important bulbs.  You may not care about the ones that illuminate your rear license plate, for example. But they are there to help public safety forces identify your vehicle. In fact, in many municipalities you can be pulled over and ticketed if ANY of the standard lights are burned out.  So not only does having all your exterior lights working improve your vehicle’s safety, it may keep you from getting a ticket.

Many newer vehicles have a light on the instrument panel that will go on if on-board computers detect voltage problems in any of your vehicle’s bulb circuits.  Sometimes it can be hard to figure out which light may be not be working since there are so many. Sometimes it’s simply a matter of replacing a bulb, but it may be an electrical problem causing the problem.  Stay legal and safe by having your service repair facility diagnose and fix a non-working light, a really bright idea, don’t you think?

The Turn Signal Mystery (Turn Signal Problems)

Some problems are easy to diagnose on a vehicle; others aren’t.  Figuring out what’s wrong with a malfunctioning turn signal sometimes fits into both categories.  By the way, if your tempted to just leave your broken blinker broken, remember you can get a ticket for not using them, not to mention you are missing a great chance to communicate your intentions to other drivers on the road.

There can be lots of signals that your signals are on the blink.  Does only the driver’s side signal not work or the passenger’s side? Do your hazard signals work? Do the lights illuminate but not flash? Can you see the indicators on the dash blinking? Do your turn signals turn off after you’ve finished your turn or do they stay on?  These are all great clues for the technician.

Here’s one common symptom to take note of.  Your signal all of a sudden starts blinking much more quickly than it used to.  It could be a simple as a burned out bulb.  But there are many different parts that go into the turn signal system.  There are fuses that blow, switches that can fail, flasher modules that go bad and light bulb sockets that can simply get corroded or dirty.  When that happens, it’s possible there’s no contact between the bulb and the socket.

So it’s understandable how tracking down the source of the problem can involve some detective work.  Your service facility has equipment that can nail down the cause of your problems. They may also consult the repair manual.  One thing to be aware of: if your vehicle has airbags, they may have to be disabled so they don’t accidentally go off.

You can make sure your turn signals are working correctly by having them checked by a trained technician.  Other drivers will thank you for showing them the courtesy of signaling your intentions.  It’s a courteous and considerate thing to do, not to mention it makes the road a safer place.

Growing Old Together (Maintaining an Older Vehicle)

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.

Not a Good Vibe (Driveshaft Failure)

When you feel your vehicle vibrating as you’re driving down the road, one cause could be something you may not have ever seen: your driveshaft.  It is underneath the vehicle and most drivers don’t climb under there to take a look very often.  The driveshaft is a cylindrical part that helps conduct the rotational power from your engine to your drive wheels.  If you have a four-wheel drive vehicle, you may have two driveshafts. 

The drive shaft has bushings, and when they wear out, that’s a likely source of the vibrations.  When the bushings are in good condition, they prevent the driveshaft from vibrating.  And if you don’t get your vehicle repaired fairly soon after discovering vibrations, they’ll continue to get worse and cause other components of the drivetrain to wear out.

The driveshaft is, of course, only one part of the drivetrain.  It includes other parts such as axles, transmission, differentials and joints.  They all work together and need to be maintained properly.  When a driveshaft fails, there can be symptoms other than vibrations.  They include difficulty turning, rattles, clunks and squeaks coming from underneath your vehicle. You may even feel a shudder when you accelerate from a stop.

Driveshafts can fail when they get corroded or damaged by rough roads, curbs and debris. A trained technician with experience working on drivetrains uses specialized equipment that doesn’t further damage the drivetrain’s other parts.  Sometimes the entire driveshaft will have to be replaced; sometimes the problems can be fixed by replacing individual components. 

Your vehicle’s drivetrain was engineered to propel you smoothly down the road.  When time and distance begin to take their toll, have your vehicle looked at by your service facility. They’ll know how to properly pinpoint what’s causing your problems and restore your vehicle to the reliable, smooth, safe machine its designers worked hard to create.

Pinch Petroleum Pennies! (Fuel Saving Tips)

If you saw a dollar bill on the ground, you’d pick it up, right? Well, whether you find that dollar on the ground or in savings at the gas pump, money is money, and here are some ways to hold on to more of it.

Slowing down is the easiest way to save fuel, especially for every speed increase over 50 mph/80 k/hr.  Tone down the speed, turn up the cash savings.  Drive smoothly (not like a race car driver) and you’ll also save money in fuel.  Aggressive, fast-start, jerky-stop habits are just pulling the bucks out of your wallet about a third more than if you drove just a little more gently.  Oh, and cruise control can help with that smooth, steady speed, so use it on the highway. Bonus!

Are you hauling around a set of dumbbells or a box of books? That extra weight is costing you dough.  Store them somewhere else.  When’s the last time you checked to see your tires were inflated properly? That’s another money saver and makes your vehicle safer.

An idle thought… don’t idle any longer than you have to.  If you will be idling for more than 30 seconds you’ll save money by turning off the engine and re-starting it.  More and more of the latest vehicles now do this automatically.

Some like it cold.  But air conditioning uses a lot of extra fuel.  If you can live with the cabin at 72 on a hot day rather than turned down to arctic freeze levels, you’ll save some cool cash.  Turn off the A/C all together can save you from 5-20 percent

The key to a fuel-efficient vehicle is keeping it well maintained.  If your spark plugs are old, your belts frayed and your brake pads worn, you’re just throwing away fuel.  Try a few of these gas-saving suggestions and while you’re at it, you’ll be helping to reduce your carbon footprint that will help everyone on Planet Earth.

When Metal Meets Metal (Wheel Bearings)

What part of your vehicle has little metal balls inside that are lubricated and allow you to cruise on down the road?  They are wheel bearings, and automotive designers might argue they are human beings’ second greatest invention of all time (the first is, of course, the wheel!).

You have a wheel bearing at each wheel.  They allow your wheels to turn freely, minimizing friction that would ordinarily slow you down when metal meets metal.  When one of your wheel bearings starts to go bad, it lets you know. A wheel bearing does its work quietly when it’s in good health but starts getting noisy when it isn’t.  People describe the noise differently.  Sometimes it sounds like road noise, a pulsating, rhythmic, sound.  That pulse speeds up when your vehicle speeds up. 

Here’s what’s happening when you hear that sound.  As mentioned, the bearing has these little metal balls inside a ring.  They have a lubricant inside to reduce friction between the balls; modern wheel bearings are sealed and they’re intended to do their job without any maintenance. 

Wheel bearings take a beating; you hit some rough potholes or go over some uneven railroad tracks. Sometimes water can get into a bearing and reduce the ability of the lubricant to do its job.  Time starts to take its toll, too. When the lubricant isn’t reducing friction like it should, the bearing can heat up. One of those little balls can start shedding pieces of metal and soon those shards start grinding up the other balls.  Friction takes over and soon your wheel isn’t turning smoothly. That’s what’s causing the sound.  If a wheel bearing is not fixed, it could eventually seize up completely, and you can be stranded.

It’s a lot easier if you heed the early warning signals, that pulsating noise.  Now, sometimes a similar noise can be caused by a bad tire, but in either case, it’s important to have it checked out. Our Tylers Auto TV technicians will be able to tell you fairly quickly what the problem is and offer a solution.

Wheel bearings generally don’t fail often and usually last from 85,000-100,000 miles/140,000km to 160,000km. But consider them a long-term maintenance item that, once fixed, will keep you heading smoothly to the next destination.
