The dashboard lights may send warnings regarding dangerous problems which require immediate attention, warn you of minor malfunctions which should be checked out by a One Stop Automotive technician, or just reminding you that one or more automotive systems are due for regular maintenance. If there is a warning light that is flashing you should stop and not drive the vehicle. One Stop Automotive can assist you with having the vehicle towed to our shop to prevent further damage.  The most common dashboard warning indicators include the anti-lock braking system, car ... read more

At One Stop Automotive we can help you get to the bottom of things and can get the mass airflow sensor working the way it is supposed to work. What is a Mass Airflow Sensor? The mass airflow sensor is located near the air filter and is an important part of the fuel injection system. It is designed to measure the volume of air flowing into the engine intake. This is very important because it regulates the air/fuel ratio mix for the engine. Signs of Failing Mass Airflow Sensor (MAF) 1. Check Engine Light (CEL/MIL): The check engine light is the first indicator of component failures. The warning light on the dashboard will illuminate to alert you of vehicle system issues. In this case you would usually get a code for a failing MAF.  The issue may be caused by the sensor itself failing, bad wiring due to rodent damage or a few other things.  When you have a Check Engine Light It is important to take the vehicle to One Stop Automotive for a diagnosis so this issue can be resol ... read more

No Burned Out Bulbs  When a customer drops off their vehicle at our shop, the very first thing we do when we pull it into a service bay is to have a second technician help check all exterior lighting. Burned out or malfunctioning bulbs are very easy to overlook. Bad bulbs are also an invitation for a "fix it" ticket from the police, and we want to help you avoid those. We do not charge labor fees to replace bulbs so its very inexpensive, just the cost of the bulb (excluding headlight bulbs).  Rest assured that when you leave our shop all of your exterior bulbs will have been checked. 

One of the most overlooked items on a vehicle is the cabin air filter. Cabin air filters are installed in your vehicles HVAC system and are designed to filter dirt, pollen and other disgusting things out of the air that you and your passengers breath inside the vehicle.  They should be inspected at every oil change and changed every 12,000 miles or once a year.  If neglected the filter becomes filled with debris and restricts the airflow, and less airflow means the cabin cannot be heated or cooled efficiently. A clogged filter also creates back pressure for the blower motor, making it work harder and contributing to possible premature failure.  Most people think these filters are checked at every service when the vehicle is in the shop, but the truth is, many of these cabin filters are hard to access so shops with poorly trained employees may miss or skip this step.  If you have asthma or other respiratory problems, it is imperative that these filters be changed ... read more

Arguably a vehicle’s most important safety system is its brakes. Specific components, including brake pads, shoes, rotors, drums and brake fluid are maintenance items that need regular replacement. A pulsation or shaking during braking can be a strong indication that the brake rotors are warped from excessive heat caused by extended or hard braking.  It is important to change brake fluid every 20,000 miles or 2 years. As brake fluid ages, it begins to corrode parts such as brake lines, calipers, caliper pistons, and wheel cylinders. It can cause the ABS light to come on and will ultimately lead to reduced braking performance. It is not uncommon for the braking system hardware to move, become dislodged or even break. In Very basic terms the hardware is what holds the brake pads or shoes in place. This is very common on vehicles with drum brakes, but still happens on disc brakes.  Modern braking systems are more complicated than the old ones, they include sensors, compu ... read more
