Lemon Law · GMC

GMC lemon law attorney in California

Owners of GMC Sierra, Yukon, Acadia, and Terrain vehicles from recent model years have filed complaints with federal regulators describing engine failures, transmission malfunctions, brake system defects, and electrical problems. The most-reported categories include engine and power train issues, followed by electrical system faults, structural concerns, and fuel system failures. Service brakes, steering, and collision avoidance features also appear in the complaint record. California's Song-Beverly Consumer Warranty Act requires manufacturers to repair or replace vehicles with defects covered by the warranty. When a vehicle cannot be repaired after a reasonable number of attempts, or when it spends too much time out of service for warranty work, the owner may have a claim for replacement or reimbursement.

Known defects

What GMC owners report, and why repeat repairs matter

These are the categories owners file most often with the federal safety regulator for the GMC model years in the record below. A complaint is one owner's report, not a finding that a vehicle is defective.

Engine failure and internal damage

Owners report knocking sounds, engine seizures, and complete failures while driving. The manufacturer has recalled vehicles with certain engines for connecting rod and crankshaft defects that can cause engine damage. Owners describe shutdowns at highway speeds requiring full replacement. Under Song-Beverly, engine failures that persist after repair attempts or require extended service periods strengthen a warranty claim. Documentation of each engine-related repair order matters when the vehicle returns for the same symptoms.

Transmission and rear wheel lock-up

The manufacturer has recalled vehicles for transmission control valve failures that can cause rear wheels to lock up while driving. Owner reports describe vehicles suddenly shifting to neutral or experiencing loss of drive power. A second recall addressed incorrect repairs from the first campaign. Transmission problems that recur after dealer service fall under the statute's protections. Each repair attempt counts toward the reasonable-attempt threshold, whether the dealer replaces parts or updates software.

Brake system malfunctions

Owners describe complete brake failure, rock-hard pedals that will not depress, and vacuum pump explosions. Recalls address brake pressure modulator valve assemblies with improperly tightened bolts and incorrectly calibrated brake systems affecting stability control and anti-lock function. Brake defects qualify as safety issues under Song-Beverly. The statute allows for replacement after two unsuccessful repair attempts when the defect is likely to cause death or serious bodily injury.

Fuel system and pump control failures

Owners report engine stalling, no-start conditions, and fuel pump control module codes. The manufacturer has recalled vehicles for fuel pump power control modules that cause fuel pumps to fail or operate intermittently, interrupting fuel flow and causing engine stalls. Additional recalls cover fuel tank assemblies missing adhesive that may leak fuel, and improperly attached fuel supply lines. Fuel system problems that leave a vehicle inoperable support claims under the Act.

Electrical system problems

The complaint record includes electrical faults ranging from battery failures and blown fuses to function-not-available warnings. Owners describe vehicles that will not start, low voltage alerts, and systems failing while driving. Electrical problems often produce intermittent symptoms dealers struggle to replicate. When service records document repeated electrical complaints, even without permanent fixes, the pattern supports a claim that the defect cannot be repaired within a reasonable number of attempts.

Steering assist loss

Owners across the GMC lineup report steering problems. A recall addresses software issues in Yukon models that cause loss of power steering assist at startup or while driving. Owners describe increased steering effort and warning messages requiring battery disconnection to reset. Steering defects that reappear after recall repairs, or that require multiple service visits, may support a claim. The statute does not require that a recall repair succeed, only that the defect affecting the vehicle persists.

The statute

When a GMC problem becomes a lemon

These are the presumptions in the Song-Beverly Consumer Warranty Act and the Tanner Consumer Protection Act (Cal. Civ. Code § 1793.22). Each applies when the defect is first reported, and the vehicle is presented for warranty repair, within 18 months of delivery or 18,000 miles, whichever comes first. They are presumptions, not predictions about any individual vehicle.

A

Two or more attempts (safety)

For a defect that could cause death or serious injury, reported within 18 months or 18,000 miles.

B

Four or more attempts

For the same non-safety warranty problem, reported within 18 months or 18,000 miles.

C

30 days out of service

Cumulative, for warranty repair, within 18 months or 18,000 miles.
