Protect Your Vehicle and Maximize Reliability

Following your vehicle’s factory maintenance schedule is one of the best ways to prevent breakdowns, maintain warranty coverage, and extend the life of your car. Learn why scheduled maintenance is essential for long-term vehicle performance and value.

Regular factory scheduled maintenance is critical for keeping your vehicle reliable, safe, and operating at peak performance. Following manufacturer-recommended service intervals helps prevent unexpected repairs, extend vehicle lifespan, and protect your investment.

At American Five Star Auto Repair & Transmission, ASE Certified technicians perform comprehensive maintenance services based on your vehicle’s make, model, mileage, and driving conditions. Scheduled maintenance may include oil and filter changes, fluid services, computer diagnostics, brake inspections, suspension checks, transmission maintenance, cooling system service, tire rotations, filter replacements, battery testing, and complete vehicle safety inspections.

For vehicles still under factory warranty, adhering to the manufacturer’s maintenance schedule helps ensure warranty compliance while maintaining optimal performance and reliability.

By conducting thorough inspections and providing clear maintenance recommendations, American Five Star helps drivers plan for future service needs and avoid costly breakdowns. Regular maintenance not only improves reliability but also enhances vehicle value and longevity.

Proper wheel alignment is key to comfortable, safe and fuel efficient driving. If you feel your steering wheel shaking back and forth or if your car drifts or pulls to one side of the road or the other, it’s likely time for a wheel alignment. American Five Star Auto Repair & Transmission can perform fast wheel alignment services that will maximize tire life, fuel efficiency and overall performance.

Exhaust System Repair & Catalytic Converter Service in Tempe, AZ

Your car’s exhaust system is one of its hardest-working components. It is responsible for directing toxic fumes away from the cabin, dampening engine noise, and converting harmful gasses into safer emissions. 
Driving with a damaged exhaust is a safety hazard and can cause your vehicle to fail state emissions testing. At American Five Star Transmission, we provide complete exhaust system diagnostics and repairs to keep your vehicle quiet, efficient, and safe. 
Signs You Need Exhaust or Catalytic Converter Repair
Exhaust issues rarely stay hidden. Bring your vehicle in for a professional inspection if you notice any of these common warning signs:
  • Loud Engine Noises: A deep rumbling, popping, or hissing sound, especially during acceleration, indicates a muffler or pipe leak. 
  • Check Engine Light: Modern vehicles use oxygen sensors to monitor exhaust efficiency; a fault often points to catalytic converter trouble.
  • Dropping Fuel Economy: A restricted or leaking exhaust system disrupts engine backpressure, causing your car to burn more gas. 
  • Vibrations & Shaking: A shaking gas pedal, steering wheel, or floorboard often signals a broken exhaust hanger or a severe system restriction. 
  • Pungent Odors: Smelling sulfur (a rotten egg smell) or heavy exhaust fumes inside the cabin is a dangerous sign of a failing catalytic converter or exhaust leak.

We repair and replace all components of your vehicle’s emission network to ensure optimal performance. Our services include:

Improve Safety, Comfort, and Vehicle Control

Your vehicle’s steering and suspension systems are essential for safe handling, ride comfort, and overall driving performance. Learn the warning signs of steering and suspension problems and why timely repairs can prevent costly damage.

The steering and suspension systems work together to provide stability, control, and a smooth ride. If your vehicle pulls to one side, feels unstable, produces clunking noises over bumps, or experiences loose or stiff steering, these are signs that professional inspection may be needed.

At American Five Star Auto Repair & Transmission, ASE Certified technicians diagnose and repair a wide range of steering and suspension components, including steering racks, tie rods, ball joints, control arms, shocks, struts, sway bars, bushings, and power steering systems. Whether your vehicle uses hydraulic or electric power steering technology, proper diagnosis is essential for safe and accurate repairs.

Delaying steering or suspension repairs can lead to uneven tire wear, compromised handling, reduced braking performance, and more expensive repairs in the future. A comprehensive inspection can identify worn or damaged components before they affect vehicle safety and reliability.
