Chapman v. General Motors LLC, 531 F.Supp.3d 1257

Background

Twenty-one named plaintiffs allege GM-equipped 2011–2016 Chevrolet/GMC 6.6L Duramax trucks incorporating Bosch CP4 high‑pressure fuel pumps are defectively designed; the pumps purportedly shed metal particles and, when paired with lower‑lubricity U.S. diesel, can cause catastrophic engine/fuel‑system failure.
Plaintiffs assert fraud, breach of implied warranty of merchantability (IWM), breach of contract, Magnuson‑Moss Warranty Act (MMWA), state consumer‑protection claims, and unjust enrichment across 49 states and D.C., totaling 114 counts in the Second Amended Complaint.
GM moved to dismiss on multiple grounds: Article III standing, pleading defects (Rule 8/9(b)), IWM defects (privity, notice, statute of limitations), MMWA jurisdictional requirements, consumer‑statute limitations (no class, no injunctive relief, preemption), economic‑loss doctrine, and to strike supplemental materials.
The Court granted the motion in part and denied it in part: 20 claims dismissed with prejudice, 1 without prejudice, 93 survive; class allegations were not stricken; certain state claims were dismissed for privity, lack of pre‑suit notice, time‑bar, economic‑loss rule, or statutory preemption.
The Court struck plaintiffs’ supplemental exhibits filed after oral argument as beyond the Court’s request and denied the sealing motions as moot; one named plaintiff was dismissed for failure to prosecute.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Standing for nationwide/state‑law claims where no named plaintiff from that state	Class treatment is appropriate; Article III standing for absent‑state claims may be deferred to class certification because the alleged harm is common.	Named plaintiffs lack Article III standing to assert state law claims where they did not suffer injury; those counts should be dismissed now.	Court follows Fallick/Amchem framework; declines to dismiss state or nationwide claims for lack of standing now—class certification is the appropriate stage.
Standing for injunctive relief	Plaintiffs allege ongoing risk of catastrophic failure and thus seek injunctive relief (recall/replacement).	Plaintiffs lack a likelihood of future injury because they won't repurchase class vehicles.	Plaintiffs adequately alleged a non‑speculative risk of future harm; standing for injunctive relief survives.
IWM claims: merchantability, privity, notice, statutes of limitations	Vehicles were defective at point of sale (point‑of‑sale breach); plaintiffs allege overpayment and latent defect; some plaintiffs gave dealer notice.	Many state laws require privity or pre‑suit notice; warranties may be limited by express warranty periods; some claims are time‑barred.	Most IWM claims survive; dismissed those for which plaintiff failed to allege required privity (AL, FL, IL, NY, TN), failed pre‑suit notice (MI Recchia), or were time‑barred (selected IL, MI, VA claims).
Fraudulent concealment: Rule 9(b), knowledge, duty to disclose, economic‑loss	Plaintiffs plead omissions (not puffery) and allege facts showing GM had superior knowledge; reliance/overpayment alleged.	Allegations are too generalized; no specific allegations of GM knowledge at time of sale; many statements are puffery; economic‑loss rule or state statutes preempt common‑law fraud in some states.	Omission‑based fraud survives Rule 9(b) in many states; Court declines broad dismissal for lack of knowledge though fixes to timing may be required later; fraudulent‑concealment counts dismissed in states where duty/claim barred (OH, NJ, SC, CA, MI, NH, LA, MS, TN, OR).
Consumer‑protection claims: adequacy of pleadings, class availability, statutes limiting relief	Plaintiffs satisfy deceptive‑conduct/causation/reliance pleading standards and allege injunctive and monetary relief; class treatment permitted.	Some state consumer statutes prohibit class actions or monetary relief, require pre‑suit notice, or preempt claims; other state rules bar injunctive relief.	Court dismisses several state consumer counts for statutory reasons (AK placeholder; GA, LA, SC, TN bar class suits; CO bars class money damages; MI MCPA exemption for auto sales; OH notice defect; NC and PA limited; LA/ND/OK injunctive limits). Others survive.
MMWA class jurisdiction (100‑named plaintiff requirement)	CAFA provides an alternative federal jurisdictional basis so MMWA class claim may proceed without 100 named plaintiffs.	MMWA requires 100 named plaintiffs for a federal‑court class action; CAFA cannot substitute.	Court follows Sixth Circuit precedent (Kuns): CAFA supplies federal jurisdiction here; the MMWA class‑size requirement does not bar the claim.
