General Motors Lemon Law Cases in Missouri — Wentzville Home-State Defendant

GM Wentzville Assembly (Wentzville, MO — St. Charles County) builds the Chevy Colorado, GMC Canyon, Chevy Express, and GMC Savana vans — making GM a home-state defendant for Missouri plaintiffs with these vehicles.

Wentzville home-state advantage

For Missouri GM plaintiffs with Wentzville-built vehicles:

• Personal jurisdiction uncontested.
• E.D. Mo. (St. Louis) federal venue automatic.
• Discovery accessible — Wentzville plant employees, records, witnesses.
• Settlement leverage — GM’s MO reputation matters.

Common GM defect patterns

Wentzville-built (Colorado, Canyon, Express, Savana)

• Chevy Colorado / GMC Canyon (newer 2023+) — early-production issues, infotainment, transmission.
• Express / Savana vans — commercial-use exclusion sometimes applies; older-platform issues.

Other GM patterns (national)

• 5.3L AFM lifter collapse — Silverado 1500, Tahoe, Suburban, Yukon.
• 6.6L Duramax LML / L5P CP4 fuel pump — diesel pickup failures.
• 8L90 / 10L80 transmission — chuggle / shudder complaints.
• Cadillac CUE / IntelliLink touchscreen — delamination, button failure.
• Bolt EV battery recall — LG battery fire risk.
• OnStar issues — module failures.
• Vacuum pump failure — Silverado / Sierra.
• 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. Strong MO cases where defect reappears post-recall.

GM IDS / BBB Auto Line

GM uses BBB Auto Line as certified IDS. MO consumers must:

• File BBB Auto Line first (§ 407.569).
• Then court action if denied.

MMPA in GM cases (post-SB 591)

• AFM lifter collapse disclosure.
• CP4 fuel pump failure disclosure.
• Bolt EV battery safety concerns.
• OnStar data practices.

Post-SB 591 ascertainable loss specificity required.

Bottom line

GM is a strong MO home-state defendant for Wentzville-built Colorado, Canyon, Express, and Savana. AFM lifter (Silverado), CP4 fuel pump (HD diesel), Bolt EV battery, and 10L80 transmission all produce strong MO cases. File BBB Auto Line first, then E.D. Mo. court action.
