What is the California CPO lemon law?
California’s Lemon Law can apply to a certified preowned vehicle if it still comes with the manufacturer’s new vehicle warranty; the key question is whether the vehicle qualifies as a “new motor vehicle” under the Song-Beverly Act, not whether it is titled as used.[1][2] If the vehicle is covered, the manufacturer may have to repurchase or replace it after a reasonable number of repair attempts, and the statutory presumption can apply if the repair history meets Cal. Civ. Code § 1793.22(b).[3]
Bottom line
In California, a certified preowned car is not automatically excluded from Lemon Law protection. If the CPO vehicle is sold with remaining manufacturer warranty coverage, it may fall within the Act’s protections.[1][2]
How the law works
1. CPO status does not control by itself
A “certified preowned” label is a marketing/condition designation, not the legal test. The controlling issue is whether the vehicle is covered by the manufacturer’s express warranty and whether it qualifies as a covered “new motor vehicle” under the Song-Beverly Act.[1][2]
The California Court of Appeal held in Jensen v. BMW of N. Am., Inc., 35 Cal. App. 4th 112 (1995) that a leased used BMW could qualify for new-car Lemon Law protections where it was sold with the manufacturer’s new car warranty. The court rejected BMW’s privity argument and explained that the Act applies to new motor vehicle manufacturers who make express warranties, with no privity requirement.[2]
2. The statutory presumption can help, but is not required
Under Cal. Civ. Code § 1793.22(b), a “reasonable number of attempts” is presumed if, within 18 months/18,000 miles, one of these occurs:
| Trigger | Requirement |
|---|---|
| Serious safety issue | Same nonconformity likely to cause death or serious bodily injury; repaired 2+ times and manufacturer directly notified |
| Repeated repairs | Same nonconformity repaired 4+ times and manufacturer directly notified |
| Excess downtime | Out of service for repair of nonconformities for more than 30 calendar days |
This presumption is helpful, but it is not the only way to prove a lemon law claim.[3]
3. Certified preowned vehicles can qualify if they retain manufacturer warranty coverage
The California Department of Consumer Affairs explains that the Lemon Law covers new and used vehicles that come with the manufacturer’s new vehicle warranty, including cars, pickup trucks, vans, and SUVs.[1] It also notes that if the manufacturer or dealer cannot fix a serious warranty defect after a reasonable number of attempts, the manufacturer must either replace the vehicle or refund the purchase price.[1]
Practical implications for CPO purchases
A buyer of a certified preowned vehicle should focus on:
- whether the vehicle had remaining manufacturer warranty coverage at sale;
- whether the defect is covered by that warranty;
- whether the vehicle was given a reasonable number of repair attempts;
- whether the repair history fits Cal. Civ. Code § 1793.22(b);
- whether the claim is against the manufacturer, not merely the dealer.[1][2][3]
Important limitations
- The Lemon Law generally applies to disputes involving the manufacturer’s new vehicle warranty, not simply any dealer promise.[1]
- Separate rules can apply to certain used-vehicle dealer warranties and to implied warranty claims, but those are different from the core Song-Beverly new-vehicle Lemon Law framework.[2]
- Whether a specific CPO vehicle qualifies can turn on the exact warranty documents, mileage, date of delivery, repair orders, and whether the defect was reported to the manufacturer or authorized repair facility.
