The 60-second answer

If your Sierra 8L90 transmission shudders, your Yukon AFM lifter fails, your Acadia 9-speed transmission slips, or your Hummer EV battery has defects, you likely qualify for a buyback, replacement, or cash settlement under your state's lemon law and the federal Magnuson-Moss Warranty Act (15 U.S.C. §§2301–2312). The most common qualifying GMC issues we handle: Sierra 8L90 transmission shudder, Yukon AFM lifter failure, Acadia transmission, Hummer EV battery.

Under both statutes, the manufacturer pays the consumer's attorney fees when the consumer prevails — meaning $0 cost to you. Easy Lemon represents GMC owners nationwide. Check open recalls for your VIN at NHTSA Recall Lookup.

IS YOUR GMC A LEMON?

When Does Your GMC Qualify as a Lemon?

GMC builds some of America's most trusted trucks and SUVs — the Sierra, Yukon, Terrain, Acadia, and Canyon. But behind that reputation for professional-grade durability lies a documented pattern of serious defects that General Motors has been slow to acknowledge and even slower to fix.

AFM/DFM lifter failures in V8-equipped Sierras and Yukons, 10-speed 10L80 transmission shudder, infotainment system crashes, and power running board failures have driven thousands of owners into an endless repair loop. If your GMC has required multiple shop visits for the same problem without a lasting fix, lemon law may compel GM to buy back or replace your vehicle.

At Easy Lemon Law, we've represented hundreds of GMC owners and know exactly how GM handles these claims — and how to beat them. Zero upfront cost. We only get paid when you win.

WARNING SIGNS

Signs Your GMC May Be a Lemon

AFM/DFM lifter failure — engine knock, power loss, or check engine light on your V8 Sierra or Yukon that returns after repair attempts.

10L80 transmission shudder — vibration or shaking during acceleration between 40–65 mph in Sierra, Yukon, or Canyon with the 10-speed transmission.

Infotainment system failures — black screen, random reboots, Bluetooth drops, or unstable CarPlay/Android Auto that the dealer cannot permanently resolve.

Recurring electrical failures — power running boards that malfunction, driver assist system faults, low battery warnings, or keyless ignition problems that keep coming back.

DOCUMENTED DEFECTS

Most Common GMC Lemon Law Defects

AFM/DFM Lifter Failures (V8)

GMC's Active Fuel Management system deactivates cylinders to save fuel, but the valve lifters can't handle the repeated cycling. The result is severe engine knock, power loss, and in extreme cases complete valve train failure. Primarily affects Sierra 1500 and Yukon models with 5.3L and 6.2L V8 engines.

10-Speed 10L80 Transmission Shudder

The 10-speed transmission in Sierra, Yukon, and Canyon produces noticeable shudder during acceleration between 40–65 mph. The issue is linked to contaminated transmission fluid and torque converter calibration problems. GM has issued technical service bulletins, but many owners report the shudder returns after the dealer flush.

GMC Infotainment System Failures

GMC's infotainment system across Sierra, Yukon, Acadia, and Terrain models suffers from black screens, random reboots, Bluetooth connectivity drops, and Apple CarPlay/Android Auto failures. Many owners report dealer software updates provide temporary relief, only for the issues to return within days or weeks.

Sierra · Yukon · Acadia · Terrain

Power Running Board Failures

The optional power running boards on Sierra and Yukon fail repeatedly — failing to deploy, getting stuck in the extended position, or producing motor grinding noises. GM has issued multiple TSBs without a durable fix, leaving many owners without the feature they paid for.

Air Conditioning System Failures

Sierra, Acadia, and Terrain owners report AC that blows warm air, refrigerant leaks with no apparent source, and compressors failing prematurely — sometimes on vehicles with very low mileage. These failures are especially common in warm climates and are not always covered under warranty.

Sierra · Acadia · Terrain

Premature Brake Problems

Sierra 2500HD, Sierra 3500HD, and Yukon brakes show abnormal premature wear, brake pedal vibration, and caliper slide pin failures. On heavy-duty work trucks, these failures represent critical safety concerns and strong grounds for lemon law claims.

FAQ

Frequently Asked Questions — GMC Lemon Law

Most states require 3–4 repair attempts for the same defect, or 30+ days out of service within the warranty period. GMC Sierra AFM lifter failures, 10-speed transmission shudder, and infotainment crashes are all documented defects that commonly qualify. Call us for a free case review.
The most frequent GMC lemon law claims involve AFM/DFM lifter failures in V8 Sierra and Yukon engines, 10-speed 10L80 transmission shudder, infotainment system crashes (black screen, Bluetooth drops), power running board failures, and air conditioning system failures.
Nothing upfront. Easy Lemon Law works on a contingency fee basis — we only get paid if we win your case. Under most state lemon laws, GMC is required to pay your attorney fees, so our representation is typically at no cost to you.
Depending on your state and case, you may be entitled to a full vehicle repurchase (buyback), a replacement vehicle, a cash settlement, reimbursement for rental cars and out-of-pocket repair costs, and attorney fees paid by GMC.
Most states require you to file within the manufacturer warranty period or within 18–24 months of purchase. Some states have longer windows. Do not wait — defects and repair records are time-sensitive. Contact us as soon as you notice a recurring issue.
It depends on the state. Some states like California protect used vehicles purchased with a warranty. If you bought a certified pre-owned GMC or one with a remaining manufacturer warranty, you may qualify. Contact us for a free evaluation.
Keep taking your GMC to an authorized dealer for repairs — not independent shops. Retain all repair orders and documentation. Do not accept any compensation offer from GM without consulting our attorneys first.
