Automotive Repair

Auto Maintenance Services
We review the manufacturer’s suggested maintenance schedule with you. This way we ensure all the recommended maintenance services are covered which will help you to keep your vehicle running trouble-free for as long as you own your car.

Brake Repair Pads & Rotors
Nothing really more common than a brake repair in the automotive business and there is certainly no shortage of shops willing to help you. Right? However, the quality of service and parts varies widely.We only use original equipment quality parts so you can rest assured you're getting a great job that will last and you can depend on.

Alignment, Shocks, And Struts
The suspension system consists of shocks and struts. Their main purpose is to keep your vehicle’s tires firmly connected to the road. When shocks and struts get worn your car looses that firm connection to the road and its stopping ability is diminished. We make sure all your Steering and Suspension components are working the way they were designed to ensuring you are driving a safe vehicle.

Tire Services
The tires on your car are very important for the function of the vehicle. You can have a well functioning engine and transmission system, but without tires, you are not going anywhere or stopping safely. Because of the importance that tires have for the use of the vehicle, it is important that they are properly maintained and cared for. Flex Auto Center provides our customers with high quality tire replacement and service in Washington and St. George, UT.

System Diagnosis & Repair
We utilize some of the current and best equipment for reading and understanding Check Engine Lights. Current technology is continuously changing, and you need up to date equipment to detect if there is an issue with your vehicle. A full diagnostic is recommended prior to initiating repairs, since a single symptom can point to MANY potential areas of solving the problem. The due diligence of a diagnostic sysytem analysis ensures that you are making informed decisions.
