Our Services

Routine Maintenance

Routine maintenance is essential for keeping your vehicle running smoothly and safely. Regular checks and services can extend the life of your car, enhance its performance, and help prevent costly repairs down the line.

Key Areas for Routine Maintenance

Rotate your tires every 5,000 to 8,000 miles and keep them properly inflated. This ensures even wear and extends the life of your tires. We will check your tire tread and refer you to a local tire shop if needed.
Pay attention to the braking system. Have your brake pads and rotors inspected at least once a year. Listen for unusual sounds when braking, as they can indicate wear.
We will use a factory wear gauge to determine the life left on your pads.
Replace your engine air filter every 15,000 to 30,000 miles, depending on driving conditions. A clean air filter improves engine performance and fuel efficiency.
Each interval has some basic maintenance involved (oil change, etc.), as well as, more detailed inspections of fluids, filters, spark plugs, and wear and tear. The manufacturer sets these guidelines to get the best possible performance based on normal driving conditions.
We use these OEM (Original Equipment Manufacturer) guidelines to keep your vehicle running at optimal performance, safety, and longevity

Advanced Diagnostics

We go beyond simply reading trouble codes. Fixed in Faith Automotive specializes in advanced electrical and drivability diagnostics to identify the root cause of difficult vehicle problems.

Using professional diagnostic equipment, live data analysis, electrical testing, and proven diagnostic techniques, we test before replacing parts—helping eliminate unnecessary repairs and guesswork.

Engine and Drivetrain Repair

Some repairs require more than basic mobile service. Fixed in Faith Automotive is equipped to handle complex engine and drivetrain repairs on-site, saving you the hassle of towing your vehicle to a traditional repair shop.

From timing system repairs and internal engine work to engine and transmission replacement, we take on major repairs that many mobile services aren't equipped to perform.

Timing belts have a service life of generally around 100k miles and have to be replaced as routine maintenance.
Timing chains also often have to be replaced between 150k-200k miles. Particularly if you hear rattling coming from the timing cover area or have a check engine light with timing codes.
Camshafts and cam phasers control the timing of your engine’s valves and play a critical role in performance and efficiency. Wear or failure can cause startup rattles, rough running, loss of power, check-engine lights, and timing-related fault codes. When these components become worn or damaged, replacement may be necessary to restore proper engine operation and prevent further damage.
Your transmission is responsible for transferring engine power to the wheels and providing smooth, reliable operation. Problems such as slipping, harsh or delayed shifting, loss of gears, unusual noises, or transmission fault codes may indicate internal or electronic issues. We provide professional diagnosis, repair, and transmission replacement to get your vehicle back on the road.
When an engine develops serious internal problems, replacement isn’t always the only option. We diagnose and repair issues involving cylinder heads, valvetrain components, oiling systems, internal engine damage, and more. When repair isn’t practical or cost-effective, we also provide complete engine replacement to get your vehicle running reliably again.

A warning light is only the starting point. We use professional diagnostic equipment and testing procedures to identify the actual cause of the fault, rather than simply replacing parts based on a trouble code.
Modern vehicles rely on complex electrical and computer systems. We diagnose wiring faults, sensor and module issues, communication problems, shorts, and other electrical concerns to pinpoint the source of the problem.
No-starts and problems that come and go can be some of the most difficult issues to diagnose. We systematically test fuel, ignition, electrical, network, and mechanical systems to find the root cause and avoid unnecessary parts replacement.
