GM Problems We Diagnose and Repair Regularly
General Motors builds solid vehicles, but certain patterns emerge across its lineup. Recognizing these issues early prevents breakdowns and keeps repair costs manageable. Here’s what brings GM owners through our doors:
Active Fuel Management Lifter Failure
GM’s cylinder deactivation system saves fuel but creates premature lifter wear in many V8 engines. You’ll hear ticking or knocking at startup that may disappear as the engine warms. Left unchecked, this damages camshafts and requires expensive engine work.
Transmission Shudder and Harsh Shifting
The 8-speed and 10-speed automatic transmissions can develop vibration during acceleration or harsh shifts between gears. Fluid condition matters significantly, and early intervention often prevents complete transmission replacement.
Air Conditioning Performance Loss
GM vehicles frequently develop A/C leaks at condenser and evaporator components. Weak cooling, intermittent function, or complete system failure usually starts with refrigerant loss that proper diagnostics can pinpoint.
Electrical System Glitches
From battery drain issues to malfunctioning power accessories, electrical problems frustrate GM owners. These range from simple battery replacement to complex body control module diagnostics requiring factory-level scan tools.
Steering and Suspension Wear
Trucks and SUVs carrying heavy loads accelerate wear on ball joints, tie rods, and control arm bushings. Loose steering, wandering on the highway, or uneven tire wear signals inspection time.
Brake System Concerns
Towing capacity and vehicle weight put demands on brake components. Pulsating pedals, extended stopping distances, or grinding noises mean your brake system needs professional attention before safety becomes compromised.
Check Engine Lights and Emissions Issues
Oxygen sensors, catalytic converters, EVAP system leaks, and mass airflow sensors trigger persistent warning lights. Proper diagnosis separates simple fixes from complex emissions repairs.
