Greeted by a Screech (Loud Noise when Starting Vehicle)

No one likes to be greeted in the morning by having someone screech at you.  The same goes for a loud, high-pitched noise your vehicle greets you with every time you start the engine.  If you're wondering if that's normal, no, it isn't.  And it is worth getting checked out.  The good news is that it might be nothing serious.  Then again, it may be.

The first things to suspect any time you hear a high-pitched sound coming from the engine are belts.  They have tension on them and they're trying to turn lots of different pulleys, pumps and other equipment the engine needs to work properly.  The noise could come from the belts starting to wear out and dry out. If one of those belts breaks at an inopportune time, not only can it strand you somewhere, the damage to the engine could be very expensive to fix.

Other things that will cause a high-pitched sound are the pulleys and tensioners.  The tensioners keep the right amount of pressure on the belts and some pulleys contain rubber that dampens engine vibrations.  The rubber in the pulleys can crack or deform with age, which prevents them from working correctly and may cause your belts to wear out.

A technician will check to see if the belts are worn or cracked.  He or she will also check the tension on the belts, the condition of the pulleys and whether all  components are aligned the way they should be.

Sometimes, the noise is nothing major to worry about, but it's still worthwhile to rule out any problems that have cropped up now or may appear in the future.  You'll have a properly running vehicle that sounds like its engineers intended… quiet and smooth.

The Third Brake Light (Third Brake Light Service)

So you thought you only had two brake lights.  Look again and you'll see one in the center at a higher level than the two on either side of the vehicle.  They're sometimes in the inside of the vehicle behind the back window, or they could be in the deck lid, on the roof or on the spare wheel carrier,

But why is that third brake on your vehicle? Experts say it helps prevent rear end collisions. Tests done by installing the third brake light in taxis and fleet vehicles showed fewer rear end crashes in the ones that had the extra light. The third brake light was mandated in new passenger cars in 1986 in the US and Canada.  The requirement was added to new light trucks and vans in 1994.

Sometimes it's difficult to know if your third brake light is even working.  Many vehicles have bulb warning systems that alert you to non-functional bulbs, but not all do. Your vehicle service facility will often check to see if all your turn signals, taillights and headlights are working during routine maintenance inspections, and they may notice that the third brake light is out. 

So, do you have to have it replaced? Not necessarily. Many areas only require one brake light to work in the rear of a vehicle. So even though new vehicles have to have the third brake light, you may not get a ticket if it eventually stops working.  But you may be missing an opportunity to drive a safer vehicle if you don't get it fixed.

In 1995, an insurance institute study found that 1986 model cars were involved in 5 percent fewer rear-end collisions from 1986-1991 than they would have expected without the extra light.

Ask your service advisor for advice.  Keep in mind that in these days of drivers distracted by everything from texting to putting on makeup while driving, you can reasonably conclude that anything that makes you more visible to the vehicle behind you adds one more—possibly life saving—safety margin.

If You Drive Like a Maniac (Aggressive Driving is Bad for a Vehicle)

When someone mentions driving like a maniac, they're not talking about you, surely? Besides the safety issues of aggressive driving, you should know that your vehicle will last a lot longer if you'll just mellow out a little.  Here are four traits good drivers follow if they want their vehicles to go the extra distance.

Cool—The driver who can't wait to get to the next stoplight is just shortening the life of his or her vehicle.  Jackrabbit starts and uneven acceleration hurts your engine because the valves and cylinder heads are stressed more.  All of those moving parts will wear out faster as well as other components that are connected.  That means things like the air conditioner, power steering pump… just about anything that attaches by a belt or a pulley.  Oh, and you'll be generating more heat.  Heat is one of a vehicle's worst enemies.

Warm—If you get in your cold vehicle which has been sitting overnight, start it up and rev the engine high, you've just put a lot of stress on your engine.  That's because you didn't let the oil (that's been sitting down in the oil pan at the bottom of the engine) get to the moving parts in order to lubricate them. Some manufacturers advise that you run your vehicle for about 30 seconds before you take off.  And if it's really cold out, you may be wise to let the engine run for a minute or two before putting a load on the engine.  Also, for the first 5-15 minutes, keep your RPMs on the low side and don't jam on the accelerator.

Smooth—You're trying to get somewhere in a hurry and have to jam on the brakes while traveling pretty fast.  Just that one time can do more damage to the brakes than you would think.  Lots of hard braking can overheat your brakes and damage your rotors, wearing them out way faster than someone who drives with a smoother touch.  Hard braking also strains suspension parts, tires and engine mounts.

Smart—You know what PRNDL stand for.  Those are the letters in your automatic transmission (Park, Reverse, Neutral, Drive, Low).  Here are another couple of letters: IQ.  A smart shifter never goes into R to D without completely stopping the vehicle, unless, of course, you're anxious to spend some big dollars on your automatic transmission. 

These days, it's common to get 200,000 miles/320,000 kilometers out of a vehicle, no problem.  It just takes regular maintenance (oil changes and regular service) and one other thing.  Showing off: showing off a little moderation in driving habits with a big payoff in the end.
