Brakes!!

One of the most crucial safety items on a vehicle. Yet they can be so over looked.

It is important to have your brake system checked regularly.
We check them every oil change here at DeMark.
You dont want to wait until you hear noise, have a major leak or the brake light comes on.

If you wait too long, this can cause damage to other components, in turn Making the potential repair cost go up.

When the brake light comes on, it is a warning that there is an issue detected within the system. This can mean low fluid, e brake issues or potential other problems.

Let's talk about Check Engine Lights!

Many people don't know this but there are several hundred reasons why a check engine light, or service engine soon light may come on.

Modern vehicles have several modules that monitor things like Fuel trims, misfires, transmission operation, brake system, evap system, exhaust components, and even HVAC and things like window switches.

When a check engine light comes on, it can be a minor issue or something more major. We always recommend at the very least having codes pulled, and more importantly, diagnosed.
There are also several codes that may not even set a check engine light.

If your check engine light is blinking, that is an indication of a more serious problem and it requires immediate attention.

If you're currently having an issue with a check engine or service engine light, get on our schedule to get it diagnosed today!
