General Motors Cases Under Montana Lemon Law
GM cases in Montana — Chevrolet, GMC, Cadillac, Buick — Silverado, Sierra, Duramax, Bolt EV, and powertrain defect patterns, with mountain-grade and cold factors.
General Motors (Chevrolet, GMC, Cadillac, Buick) holds a large Montana market share — Silverado, Sierra, Tahoe, and Suburban are common in ranch, oil-patch, and work use. Cases are pursued under the Montana Lemon Law, the CPA, and Magnuson-Moss.
Common GM defect patterns
- 6.2L / 5.3L V8 lifter / AFM-DFM failures — collapsed lifters, engine damage.
- 8-speed (8L90/8L45) transmission shudder — extensive class-action history.
- 10-speed transmission issues.
- Duramax diesel — cold-start and emissions-system issues (relevant in deep cold).
- Chevy Bolt EV — battery fire recall (LG cells), cold-weather range/charging.
- Electrical / BCM faults (mag-chloride-corrosion relevant).
Montana GM market
- Silverado / Sierra for ranch, oil-patch, and plowing use (under 15,000 lbs covered).
- Tahoe / Suburban family-hauler segment.
- Cadillac / Buick in the Bozeman and Billings luxury segments.
Safety + CPA leverage
The Bolt battery-fire recall is a serious safety matter, and 8-speed shudder class-action history plus AFM/DFM lifter TSBs support a CPA theory with a discretionary treble. Mountain-grade towing stresses GM transmissions; mag-chloride accelerates corrosion.
Bottom line
GM cases — V8 lifter failures, 8-speed shudder, Duramax, and Bolt battery issues — are well-positioned under Montana law. Use in-state arbitration, and act before 18,000 miles. Get a free case review.
