California has Song-Beverly with its civil-penalty stick. Michigan is the operational headquarters of Ford, GM, and Stellantis — meaning Big Three engineering decisions are made in Detroit but litigated nationwide. The Michigan New Motor Vehicle Warranty Act is the rule of the road in Big Three lemon-law cases filed at home. Here's how the two states stack up against each other.
Side-by-side comparison
| California | Michigan | |
|---|---|---|
| Presumption | California Song-Beverly: 4 attempts OR 2 attempts for a safety defect OR 30 days OOS in 18 months / 18,000 miles. | Michigan: 4 attempts OR 30 days OOS within first 24,000 miles or warranty period. |
| Practical takeaway: Similar thresholds. Michigan's mileage-based window (24,000 miles) is more lenient than California's calendar-and-mileage combo. | ||
| Statute | Cal. Civ. Code §§ 1790–1795 (Song-Beverly). | Mich. Comp. Laws § 257.1401 (Michigan New Motor Vehicle Warranty Act). |
| Practical takeaway: Song-Beverly is more developed and powerful; Michigan's statute is more procedural and less penalty-driven. | ||
| Civil penalties | California Song-Beverly § 1794(c): up to 2× actual damages for willful violations. | Michigan: standard damages + attorney fees, no statutory civil-penalty multiplier. |
| Practical takeaway: California's 2× penalty is unmatched. Michigan's case-fee economics are still strong but lack the penalty stick. | ||
| Arbitration | California: manufacturer-sponsored only (BBB AUTO LINE / NCDS) — not required. | Michigan: manufacturer-sponsored optional; BBB AUTO LINE is the common path. |
| Practical takeaway: Neither state requires consumer arbitration before suit. Both allow direct federal MMWA filing. | ||
| Federal venue | C.D., N.D., E.D., S.D. Cal. — 9th Circuit. | E.D. Mich., W.D. Mich. — 6th Circuit. |
| Practical takeaway: Both circuits favor consumers on MMWA fee-shifting. Michigan's E.D. Mich. is in Detroit, putting Big Three defendants on home turf. | ||
The verdict
California's edge: the Song-Beverly civil-penalty provision drives larger settlements. Manufacturers settle Song-Beverly cases at higher values to avoid the 2× exposure.
Michigan's edge: jurisdiction over the Big Three's home court — discovery against Ford, GM, or Stellantis happens in their home circuit, which can be a strategic advantage on document production.
Why MMWA wins regardless: federal MMWA gives identical fee-shifting in both states. We typically file Song-Beverly + MMWA in California for the civil-penalty stick. In Michigan we file Michigan lemon-law + MMWA — the manufacturer is at home and can't run discovery delays.
