California Lemon Law vs. Breach of Warranty

The California Lemon Law and a general breach-of-warranty claim are closely related — but California Lemon Law is the specialized, stronger version. “Lemon law” is the common name for the Song-Beverly Consumer Warranty Act, which is itself a specialized breach-of-warranty statute for consumer goods. A “generic” breach-of-warranty claim under California Commercial Code § 2725 also exists but lacks Song-Beverly’s lemon presumption, civil penalty, and attorney-fee shifting. California lemon law attorneys plead Song-Beverly whenever it applies.

 

 

Side-by-Side Comparison

Feature California Lemon Law (Song-Beverly) Generic Breach of Warranty (Comm. Code § 2725)
Scope Consumer goods including vehicles Any sale of goods
Lemon presumption Yes (§ 1793.22) No
Civil penalty Up to 2× damages for willful violations No
Attorney’s fees Yes — paid by manufacturer (§ 1794(d)) No (unless contract provides)
Disclaimer rules Strict — § 1792 limits dealer disclaimers UCC default rules apply
Statute of limitations 4 years 4 years

 

 

When Each Applies

  • Song-Beverly (lemon law) — consumer vehicles sold or leased with a manufacturer’s express written warranty, including most cars, trucks, SUVs, motorcycles, RVs, and small commercial vehicles. Default choice for California lemon law claims.
  • Generic breach of warranty — commercial-purchase vehicles outside Song-Beverly’s scope (large trucks, equipment, vehicles purchased by businesses with more than 5 vehicles), or sales where Song-Beverly is excluded.
  • Federal Magnuson-Moss — also pleaded alongside Song-Beverly; provides federal jurisdiction and incorporates state implied-warranty law.

 

 

Why Song-Beverly Is Almost Always the Preferred Claim

For California consumer vehicles, Song-Beverly is dramatically stronger than generic breach of warranty:

  • The lemon presumption shortcuts proof of “reasonable number of attempts”
  • The civil penalty doubles the manufacturer’s exposure for willful conduct
  • The attorney-fee provision makes representation universally accessible
  • The implied-warranty rules cannot be disclaimed on new goods

California lemon law attorneys plead Song-Beverly, plead Magnuson-Moss as a federal backstop, and rarely rely on a generic breach-of-warranty theory alone.
