General Motors Cases Under South Dakota Lemon Law

GM cases in South Dakota — Chevrolet, GMC, Cadillac, Buick — Silverado, Sierra, Duramax, Bolt EV, and powertrain defect patterns, with cold factors.

General Motors (Chevrolet, GMC, Cadillac, Buick) holds a large South Dakota market share — Silverado, Sierra, Tahoe, and Suburban are common in ranch and work use. Cases are pursued under the South Dakota Lemon Law, Magnuson-Moss, and the DTPA.

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.
  • Chevy Bolt EV — battery fire recall (LG cells), cold-weather range/charging.
  • Electrical / BCM faults (cold/de-icer relevant).

South Dakota GM market

  • Silverado / Sierra for ranch and ag use (under 15,000 lbs covered).
  • Tahoe / Suburban family-hauler segment.

Safety + DTPA 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 DTPA misrepresentation theory. Winter de-icer accelerates corrosion.

Bottom line

GM cases — V8 lifter failures, 8-speed shudder, Duramax, and Bolt battery issues — are well-positioned under South Dakota law. Report by 12,000 miles, use any manufacturer IDS, then sue. Get a free case review.
