If you’ve ever stepped on your brake pedal and felt your vehicle vibrate, that’s a signal that you shouldn’t ignore.  A pulsating brake pedal is a sign that something is wrong.  Braking action should be smooth, sure, and quiet, not shaky and noisy. Most newer vehicles have disc brakes, called that because they have a round, flat disc connected to each wheel.  Those discs are the rotors. Other parts called brake pads are squeezed against those discs when you press on the brake pedal. Remember that vibration we mentioned? That can be caused by the rotor not having a straight, true surface. Rotors can heat up from friction and warp.  They can become thinner from constant wear.  Rotors can rust from the elements they’re exposed to, such as rain, snow ice, and salt.  They can get grooves in them from so many contacts with the pads.  The signs of worn rotors are vibrations, grooves on the rotor (which you can see sometimes through op ... read more

Ever wonder how all-wheel-drive or 4-wheel-drive vehicles get the power from the engine to the front and rear wheels? The magic happens in what's called a transfer case.  In some all-wheel-drive vehicles, it's sometime called a power take-off unit, or PTU. Inside the transfer case is a set of gears.  And to keep those gears meshing smoothly, they have to be lubricated and kept cool.  What does that is called transfer case fluid. Depending on your vehicle's type of transfer case, it is filled with either an automatic transmission fluid, a gear oil that's a bit thicker or transfer case fluid designed to be use for your transfer case. As happens with all lubricating fluids, the transfer case fluid has things in it that break down the older they get.  They have corrosion inhibitors, detergents and anti-foaming agents that keep the lubricant from getting air bubbles in it. Transfer cases don't have filters in them to clean out impurities. If you don't have your transfer ... read more

When you get in your vehicle, how does it smell? If it's not so nice, it may be time to have your cabin air filter changed. It's not the same one that filters out the air used in the engine.  The cabin air filter screens out dust and other particulates from the outside air so when it enters the cabin, you don't have to breathe them in when you're driving.  Maybe your commute finds you traveling along dusty rural roads, or maybe you pass by some city factories that have smokestacks spewing out smoky exhausts.  Or in spring, maybe you notice your allergies acting up because of the pollen in the air.  The cabin air filter will remove a lot of those things. The more it filters out, the more those small particles add up.  That reduces how much airflow the heating/air conditioning system can handle, and you may notice not as much air is coming through your vehicle's vents.  That can also be a sign you need your air filter replaced. Our technicians will remove an ... read more

Brakes are one of your vehicle's most important safety components, and you may have noticed that they don't stop as surely as they used to.  Maybe it takes you applying a little more pressure to them than before, or perhaps you get the feeling that they're not stopping you as quickly. Those could be signs that your brake fluid needs changing.  Hydraulic brake systems use a fluid that enables the brakes to apply their stopping power to the wheels.  That fluid can wear out, degrade, become contaminated or pick up air and moisture.  All those can eventually contribute to brakes that feel sluggish. Driving with old, worn-out brake fluid may also shorten the lifespan of other braking components. Our technicians can evaluate your brake fluid to see if it needs changing. Your vehicle's manufacturer recommends how often that should be done, and when it needs changing may depend on how and where you drive. Our technicians can check the condition of your brake fluid when you ... read more

You are heading down a flat, newly paved street when all of a sudden you feel it.  Your vehicle jumps a little bit when you're accelerating and changing gears.  You know it's not the surface of the road because it's smooth as silk.  So what did you just feel? That kind of jumping—or grinding or slipping—during gear changes could be a sign of trouble in your automatic transmission.  And it's important to get it checked out fairly soon because some transmission problems that aren't fixed early can lead to more involved and expensive repairs. By far most vehicles on the road in North America have automatic transmissions, and they are workhorses.  Unlike early cars with balky, hard-to-shift manual transmissions, the latest automatics allow you to drive without having to even think about gear changes.  But you should know about a few signs of trouble to look for if they ever start showing up. When you first get going and shift your vehicle from Par ... read more

No matter what the temperature is outside, it's important for your vehicle's engine to remain cool, calm, and collected.  Well, cool, anyway. If your vehicle has a gasoline engine, it's powered by a bunch of explosions involving spark plugs, pistons, gasoline, and air.  And the by-product of all those things working together? HEAT. There's a whole cooling system to keep everything at a tolerable temperature for your engine's parts, and a key part of that is the water pump.  Technically, it's pumping more than water. It should actually be called the "coolant" pump since the liquid that circulates through the system is a mixture of water and coolant.  Basically, the water pump keeps this coolant moving through your engine, where it picks up the engine heat, and then is pumped into the radiator where it gets rid of that heat.  When a water pump fails, the engine heat can build up.  When you get a warning light on the dash (either a gauge or a light) that show ... read more

You know that sinking feeling when you realize one of your tires has a problem.  It may be making an odd noise or behaving oddly when you're driving.  You may hit a pothole or curb and one suddenly goes flat.  Or you may head back to your vehicle and discover it has one tire deflated without a clue of what must have happened to it. With a lot of different tires hitting the streets these days, the issue of whether to have a tire repaired or replaced can be tricky, and we strongly recommend you have a trained technician help you make that decision.  One of the most common causes of flat tires is picking up a screw or nail in the tread area.  Many of those can be patched and plugged if the puncture isn't more than ¼ inch/6 mm in diameter. Most tires can handle two of this type of repair, but any more and you should buy a new tire.  If there's a puncture or bulge in the sidewall or shoulder, the rule of thumb is it's not repairable.  The sidewall d ... read more

When you head out to your vehicle after it's been parked and notice oil leaking underneath it, that's something to have looked at right away.  Oil leaks mean your oil level is probably low and running a vehicle in that condition can lead to expensive repairs. While there are many reasons oil leaks develop, one possibility is a bad valve cover gasket.  Vehicle engines have a cover bolted over the spot where the engine valves are, and that cover keeps the oil inside the engine. In between the cover and the engine is a gasket that keeps that seal tight.  But after many years of high engine temperatures and vibrations, that gasket or the bolts that hold on the valve cover can fail or loosen, and oil can leak. You may see dirty oil on the valve cover in the engine compartment, near the spark plugs, or around the bolts that hold the valve cover on.  All those are signs of leakage and time to bring your vehicle in for our technicians to check out. In some vehicles, taking ... read more

You may have noticed your vehicle going through lean times.  By that, we mean it's literally leaning to one side.  When you notice that, you should get it checked out at your service facility soon because you could have a serious problem. Many things can cause a vehicle to lean.  You may have problems with your struts, shocks or springs.  They all work in tandem to make your ride more comfortable.  The struts bear the weight of the vehicle's body, the shock absorbers employ a piston that keeps your tires in contact with the road and controls movement of the vehicle's body.  Springs also absorb impacts from uneven road surfaces. If these components get stuck, either too high or too low, they cause your vehicle to lean.  That's because that side of the vehicle isn't at the height it is designed to be.  A technician will determine where the problem is.  Outside elements such as moisture plus hard knocks to these components can weaken them, even ... read more

When you head to the doctor, you probably have it in your mind what you're going to say about why you don't feel good.  That way your doctor can use that information to diagnose your problem. You might want to think of that same approach when you take your vehicle in for a repair. Experts say what will help the service advisor most is for you to bring in some well-organized descriptions about your vehicle's issues.  You might even want to write them down so you don't forget.  Is there an unusual smell?  What does it smell like?  Does the problem happen first thing after starting out? If there's an odd sound you hear, is it dependent on speed?  Does it change when you turn a corner?   Keep your expectations realistic.  Some conditions may take a long time to diagnose and repair.  If you go thinking you'll be in and out in no time, you might be disappointed when you're told there are other customers ahead of you and you may have to come b ... read more
