Don't Neglect Your Spare (Spare Tire Care)

If you've ever had a flat tire, then you know welcome it is to have a spare tire that is properly inflated, in good shape and easy to get to.  Problem is many of us don't even give our spare tire (if we even have one) a second thought.

If you have an SUV or truck with a spare, it may be mounted outside the vehicle, such as on the tailgate or underneath the vehicle.  All of them, especially those underneath, take the brunt of debris, moisture, salt and dirt from the road surface, a potpourri of corrosion potential.  The hardware that holds these on can rust into a solid mess, making it hard for you or even a roadside assistance service to get off. 

If you have one of those, have it checked and maintained at your vehicle repair facility on a regular basis.  They should be lubricated and cleaned periodically, and some recommend doing this service every time you have your tires rotated.  If the spare is the same size as the tires on the vehicle, it may be a good idea to have it rotated with the others. 

Some vehicles have compact spares that are in a small well in the trunk or some other spot. Most drivers don't pay any attention to them.  Over time, air leaks out of those spares, leaving them flat when you most need them.  When you have your vehicle in for service or routine maintenance, ask your service advisor for his or her advice on making sure the spare is inflated properly and cleaned, usually at least twice a year.

You may not know it, but your vehicle may not have any spare at all.  Instead, it may have an inflator kit that you are supposed to use to inflate and seal a flat tire.  That sealant has a limited life span and should be replaced every few years.  Check with your service advisor to make sure the kit is up to date and will do the job when called upon.

Manufacturers know a flat tire's always a possibility.  No matter what contingency solution they've included with your vehicle, keep it in shape and in good working order.  When you need it, you'll be very glad you did.

A Sticky Brake Situation (Parking Brake Service and Maintenance)

We've all been there.  You park your vehicle on a steeper than usual hill and worry about it rolling down while you're running your errands.  So you decide you'll use the parking brake.  When you get back, you release the parking brake, hit the ignition, put it in gear and—uh, oh—you can feel the parking brake is still on.  It's stuck.  What do you do now?

Welcome to the world of infrequently-used parking brakes.  Yes, they do stick for several reasons. It's common for components to corrode and get locked up.  Sometimes if you have applied it extra hard, it can jam.  Could be a rusty cable, could be a spring that doesn't return the brake to its disengaged position.  Some pieces just break when they're stressed for the first time in a while. A caliper or the pivot arm it's on can also stick.

There are a few things you can try to unstick it.  Carefully rock your vehicle by putting it first in drive and then reverse.  You have to be careful doing that, though, because sometimes you can damage the transmission.  You can try working the parking brake control a few times to see if that will loosen the corrosion.  If you can't unstick it, you can try driving slowly a short distance to a repair facility near you.  Sometimes it won't cause damage to the brakes but it depends on how tightly the parking brake was applied and what was stuck.  You may also have to have your vehicle towed to a repair facility.

In any case, once you've seen these symptoms, have your vehicle brakes looked at by a professional who can fix the root of the problem.  Better yet, don't let your vehicle get in this condition; regular maintenance and inspections by a trained technician should prevent you from getting in a jam somewhere thanks to a stuck parking brake.  You could use a "brake" like that.

Beginning to See the Light (Check Engine Light Diagnostics)

It's a light many drivers fear they'll see turn on at the most inopportune time.  It's the one on the dash that says "Check Engine," "Service Engine Soon," or it may be simply an engine-shaped light. Your first instinct may be to pull off to the side of the road and turn off the engine.

The truth is that Check Engine light can be pointing to problems as simple as a loose gas cap. But it could be as serious as a severely misfiring engine.  Don't ignore it because it's there to help you avoid an expensive repair it is designed to alert you to, to tell you something's not quite right.

Your vehicle has a connected system of computers and sensors constantly checking to see that all systems are working the way they should. If something isn't, the system will turn on the Check Engine light.

If it's flashing, that could be serious. Look at some of the other warning lights or gauges such as heat or oil pressure. They could be telling you your vehicle's problem should be checked right away. In that case, if you can, safely pull off the road and shut the vehicle down. If your vehicle loses power and the Check Engine light is on, try not to push the demands you are making on the engine, such as towing or accelerating hard.

Simply put, a flashing Check Engine light should be checked out by a professional as soon as possible.

If the Check Engine light is on steadily, manufacturers say it means there's a problem, but it probably doesn't require immediate service.  The system is designed to remember the problem it found and store it (as a code) so it can be retrieved later.

When you do bring your vehicle in to have us see what's behind the Check Engine light coming on, we’ll hook your vehicle up to a diagnostics tool that can reveal the clues the engine's computers have stored.  It takes a trained technician to understand those clues, like a doctor who can interpret a patient's symptoms and come up with the correct diagnosis. Some newer vehicles can even be checked remotely.

Once we figure out the problem and repair it, you'll be back on the road again. It's nice to know the Check Engine light is your sentry, standing by to alert you the next time you begin to "see the light."
