That Squeal is Telling You Something (What Causes Squealing While Steering)

If you hear a squealing noise when you turn your vehicle, it’s trying to tell you something is wrong.  After all, it never made that noise before, right?  The sound  you hear may becoming from a few sources.  Let’s take a look (or a listen) to some of the possibilities.

First, you almost certainly have power steering in your vehicle. Without power steering, you practically have to have arms like Arnold Schwarzenegger to turn, so automakers have technology to assist your steering, either mechanically or electrically.  For a long time, the most common power steering has been hydraulic, using a belt to supply power from the engine that turns a power steering pump full of a fluid that helps you steer. 

Sometimes that fluid gets low because of a leak or some other problem.  The belt could wear out and start squeaking, and you might feel the steering start to become harder.  Your service repair facility can figure out the problem and offer some solutions.

Another cause could be in your suspension.  Some components may not be getting lubricated like they should.  Or you may be hearing your tires squealing when you are turning. 

Properly working steering is a huge safety factor for your vehicle’s operation.  Your steering affects handling, vital to your well-being as well as that of drivers around you.  So take your vehicle over to your repair facility and have it checked out.  You’ll be doing everyone on the road—including yourself—a big favor by listening to your vehicle. When it comes to steering, silence really is golden.  Get that squealing repaired and get back to safe driving.

Low Power Mystery (Ignition Coil Service)

It’s no fun when your vehicle just doesn’t run the way it used to.   You may notice (especially in cold weather) the engine won’t start easily or when it does start, it doesn’t run smoothly. It may not have much power at all. You also may have had to stop at the gas station more often, a sign your fuel economy isn’t what it used to be. 

There could be a few different things that cause those symptoms, but one culprit could be a bad ignition coil. The coil takes the voltage from your battery and multiplies it before that power is sent over to a spark plug. That allows the plug to fire off a good jolt of electricity that ignites the fuel in your cylinder and powers the engine. 

There’s usually one ignition coil for each cylinder (or sometimes for a pair of cylinders). If only one of them is not pushing out enough electricity, it can cause big trouble with your engine performance.  Other signs of a bad ignition coil include engine backfire, an oil leak and your Check Engine light coming on.   When that light comes on and you have some of those other signs, you need to have your repair facility check things out fairly soon because you may be damaging your engine and wind up with a far more expensive repair.

A technician will check for a computer code to pinpoint which cylinder is having the problem.  Using other diagnostics, the technician can rule out other components that might be causing the engine to misfire.  Ignition coils usually last 100,000 miles/160,000 km, but other engine conditions can cause them to fail before then. 

Your service advisor may suggest getting all your coils replaced even though only one is malfunctioning. That’s probably a good idea in a higher mileage vehicle since the other coils may be close to failure, too. It’s also wise to do that if your vehicle’s coils are located in a hard-to-reach spot so you likely won’t have to spend the money for that labor again when another one fails.

When Your Air Bag Light Comes On (Illuminated Air Bag Light)

There are some dashboard lights you should pay more attention to than others.  One is the air bag light.  If it’s on and your vehicle is in an accident, your air bags probably won’t do their job.

Automakers began installing air bags in the late 1990’s since they were mandatory in the United States, and manufacturers have included them in Canadian vehicles as well.  Safety experts say using a seat belt in combination with an air bag gives passengers the best chance of surviving a crash and minimizing serious injury.

The air bag warning light takes a few different forms.  Some look like a picture of a belted passenger with an inflated air bag from a side view.  Or there may be a warning light that says something like “Air Bag,” “SRS” (for supplemental restraint system), “Airbag Deactivated” or “Air Bag Off.”

Different things cause the air bag light to come on.  Your vehicle may have been in an accident during which, while the air bags didn’t inflate, crash sensors were activated.  Some of them may be connected with your vehicle’s seat belts.  A technician can reset the air bag if this has happened.

Fuses can also blow which will cause the air bag light to come on.  Another possible cause? A sensor that tells the vehicle’s computer whether or not there is someone riding in the passenger front seat may be malfunctioning. 

Air bags are not for the do-it-yourselfer.  They are sophisticated systems that require specialized training and equipment to diagnose and repair.  If an air bag light is on, take it to a qualified service repair facility.  One more thing: remember that safety experts have designed air bags to work in conjunction with seat belts for maximum protection in accidents.  So always wear your seat belt.
