General Motors Lemon Law Cases in Connecticut

GM (Chevrolet, GMC, Cadillac, Buick) covers a wide CT market. Connecticut Lemon Law (§ 42-179) and CUTPA apply.

Common GM defect patterns

• 5.3L AFM lifter collapse — Silverado, Tahoe, Suburban, Yukon.
• 6.6L Duramax LML / L5P CP4 fuel pump — diesel pickup failures.
• 8L90 / 10L80 transmission — chuggle / shudder complaints; class actions filed.
• Cadillac CUE / IntelliLink touchscreen — delamination, button failure.
• Bolt EV battery recall — LG battery fire risk; major recall.
• CT6 / ATS / CTS — various electrical, transmission issues.
• OnStar issues — module failures.
• Vacuum pump failure — Silverado / Sierra; causes brake-assist loss.
• Equinox / Terrain 1.5T — multiple recalls.

Bolt EV battery recall

The Chevy Bolt EV battery recall (LG NMC chemistry, fire risk) affected 2017-2022 Bolt EV/EUV. Recall remedy included module replacement or full battery replacement.

For Connecticut consumers:

• Recall completion = strong case if defect reappears.
• CUTPA claims for delayed remedy.
• Significant settlement leverage.

GM IDS / arbitration

GM uses BBB Auto Line as certified IDS. CT consumers can:

• File DCP arbitration.
• File BBB Auto Line.
• File court action.

DCP is generally preferred.

CUTPA in GM cases

• AFM lifter collapse disclosure (GM was sued and settled multiple times).
• CP4 fuel pump failure disclosure.
• Bolt EV battery safety concerns.
• OnStar data practices (separate CUTPA exposure).

Bottom line

GM is fully covered under Connecticut Lemon Law. AFM lifter, CP4 fuel pump, Bolt battery, and 10L80 transmission all produce strong CT cases. File DCP arbitration or court action with parallel CUTPA + Magnuson-Moss.
