Engine Maintenance & Repairs

A properly functioning engine is essential for the power and efficiency GMC is known for. If your GMC Yukon or Acadia is showing signs of rough idling, loss of power, or overheating, our skilled technicians provide fuel system cleaning, ignition repairs, and cooling system diagnostics to restore smooth operation. Regular tune-ups and oil changes also help extend engine life and prevent costly repairs.

Transmission Service & Diagnostics

GMC trucks and SUVs require a well-maintained transmission for smooth shifting and towing capability. If your GMC Sierra or Canyon is experiencing slipping gears, delayed engagement, or transmission fluid leaks, we offer comprehensive fluid exchanges, torque converter repairs, and full rebuilds to keep your drivetrain performing optimally.

Brake System Repairs & Inspections

With the power and weight of GMC vehicles, a reliable braking system is crucial for safety. If your GMC Terrain or Yukon XL has squealing brakes, a spongy pedal, or requires longer stopping distances, our team performs brake pad and rotor replacements, fluid flushes, and ABS diagnostics to ensure top-tier stopping power.

Suspension & Steering System Solutions

A smooth ride and precise steering are essential for both comfort and control. If your GMC Envoy or Acadia is experiencing uneven tire wear, excessive bouncing, or steering wheel vibrations, we provide shock and strut replacements, wheel alignments, and power steering system repairs to restore stability and handling.
