Not every vehicle problem qualifies under Lemon Law—but certain defects appear frequently in GM vehicles and may meet the legal threshold.

Transmission Problems

Many GM owners report:

• Jerking or slipping
• Delayed shifting
• Complete transmission failure

These issues can:

• Affect drivability
• Create safety risks

Engine Issues

Common complaints include:

• Stalling while driving
• Excessive oil consumption
• Loss of power

An engine defect is almost always considered “substantial.”

Electrical System Failures

Modern GM vehicles rely heavily on electronics.

Defects may include:

• Dashboard malfunctions
• Backup camera failure
• Infotainment freezing
• Warning lights that don’t function properly

These can impact safety, especially with driver-assist features.

Brake and Steering Problems

Safety-related defects are taken seriously.

Examples:

• Brake failure or delayed response
• Steering wheel locking or pulling

These often qualify with fewer repair attempts.

HVAC and Comfort Systems

While sometimes minor, repeated failures in:

• Air conditioning
• Heating systems

Can qualify if they significantly affect usability—especially in Texas heat.

Key Takeaway

If your GM vehicle has repeated issues—even if the dealer says “we fixed it”—you may still have a Lemon Law claim.
