We all want to breathe clean air and keep our planet green. One of the ways to do that is by requiring all vehicles with internal combustion engines to pass an emissions test. That’s because these vehicles can be big polluters.
Everyone wants their car to pass the test so they can continue their day-to-day driving routine. But then comes that one day when they tell you your vehicle has failed. Why does that happen?
One of the most common reasons is that your gas cap is leaking or loose (or maybe you don’t even have one on your vehicle!). The gas cap is supposed to seal in vapors, but sometimes its seals or gaskets dry out or crack. Replace it, and you’re good to go.
Another common reason your vehicle failed the test is that your catalytic converter isn’t doing its job. It is supposed to convert toxic gases from your engine into ones that don’t pollute the air. There are many reasons the catalytic converter may not be working. It may be physically damaged, or the steady flow of exhaust gases has fouled the converter.
You may have a bad oxygen sensor. It’s supposed to measure how much oxygen is in your exhaust. This can cause the air-fuel mixture to be too rich, resulting in too many hydrocarbons in the exhaust. Your ignition system may also have problems, such as worn-out spark plugs. Dirty fuel injectors can contribute to excess emissions.
Believe it or not, a dirty engine air filter may be the culprit. If it hasn’t been replaced for a while, your vehicle may be emitting too many hydrocarbons - something that will cause your vehicle to fail the emissions test.
You can usually avoid a failed emissions test by maintaining your vehicle regularly. The best way to do that is by bringing it to our trained technicians, so your vehicle gets the service it needs, scheduled and non-scheduled. Plus, you’ll be doing your part to keep our air clean.

If your vehicle had something in its design or production that the manufacturer had figured out had an unanticipated problem, you'd want to know about it. And you'd want it fixed. There is something that can help drivers with just such a scenario. It's called a Technical Service Bulletin, or TSB.... More

You notice when your smartphone's battery starts to go weak on you. It runs out of juice faster than it did when it was new. Bet you pay attention to that pretty closely. Unfortunately, many of us don't pay the same attention to the battery in our vehicles. If your battery got you through the c... More

You might remember a hit TV sitcom that was set in a bar, a place where "everybody knows your name." The idea, of course, is people feel more comfortable where they aren't just another customer among many; they're special because their relationship goes back a few years. That comfortable relat...
