General Motors Cases Under New Hampshire Lemon Law

GM cases in New Hampshire — Chevrolet, GMC, Cadillac, Buick — Silverado, Equinox, Bolt EV, and powertrain/infotainment defect patterns, with road-salt factors.

General Motors (Chevrolet, GMC, Cadillac, Buick) holds a large New Hampshire market share — Silverado, Sierra, Equinox, and Tahoe are common in rural and work use. Cases are pursued under the New Hampshire 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.
  • Chevy Bolt EV — battery fire recall (LG cells), cold-weather range/charging.
  • CUE / GM infotainment failures (Cadillac).
  • Electrical / BCM faults (road-salt corrosion relevant).

New Hampshire GM market

  • Silverado / Sierra for rural, trades, and plowing use.
  • Equinox / Trax core volume.
  • Tahoe / Suburban family-hauler segment.

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 CPA damages with the treble multiplier. Road salt accelerates GM brake-line and electrical corrosion.

Bottom line

GM cases — V8 lifter failures, 8-speed shudder, and Bolt battery issues — are well-positioned under New Hampshire law. Use the Arbitration Board for speed. Get a free case review.
