California AB 646: Rules for catalytic-converter and anti-theft warranties

Creates a safe harbor treating vehicle anti-theft and catalytic-converter protection warranties as express warranties (not insurance) if they meet insurer-backed and disclosure conditions—affecting dealers, warrantors, and insurers.

The Brief

AB 646 sets a statutory path for certain vehicle protection product warranties—including those aimed at catalytic-converter theft—to be treated as express warranties rather than automobile insurance if specific conditions are met. The bill requires warrantors to secure an admitted-insurer policy that covers 100% of warranty obligations, permits direct claims against the insurer after a 60‑day warrantor default, and imposes detailed written-disclosure and eligibility requirements.

The measure matters because it changes how these products are regulated and how consumers can recover when a product fails. It creates solvency protections for consumers (an insurer backstop and direct claim right), standardized consumer disclosures (including bold notices and a “not insurance” statement), and enforcement tools for the insurance commissioner—while also imposing operational and insurance costs on warrantors and exposing insurers to direct claims risk.

At a Glance

What It Does

The bill creates a statutory exception so a vehicle protection product warranty is an express warranty (not insurance) if the warrantor carries an admitted insurer policy covering 100% of its obligations, files that policy with the insurance commissioner, and includes specified written disclosures and eligibility conditions. It also gives warrantyholders a right to make a direct claim on the insurer if the warrantor fails to pay within 60 days.

Who It Affects

Primary targets are warrantors and sellers of anti-theft and catalytic-converter protection products, auto dealers who sell or offer those products, admitted insurers that insure warrantors, and vehicle owners seeking reimbursement after catalytic converter or vehicle theft. The insurance commissioner and consumer protection enforcers are also implicated.

Why It Matters

How a product is classified determines regulatory oversight, consumer remedies, and market practices. This bill attempts to preserve a market for protection warranties while forcing a full-insurer backstop and standardized disclosures—shifting compliance costs to warrantors and direct legal exposure to insurers.

What This Bill Actually Does

AB 646 sets out a compliance checklist a warrantor must complete to avoid being treated as selling insurance. The core requirement is an admitted-insurer policy that covers 100% of the warrantor’s contractual obligations; the policy must be filed with the insurance commissioner and allow the warrantyholder to pursue payment directly from the insurer if the warrantor does not satisfy a covered claim within 60 days after a complete proof-of-loss.

The law limits a warrantor to one active filed policy at a time and contains rules about when a cancellation becomes effective and what the warrantor must do if its insurer cancels.

The bill also prescribes how warranties must look on paper. Warranties must be written and include clear statements about benefit limits (different rules for full-vehicle protection versus catalytic-converter–only products), a required statement that the agreement is not insurance, disclosure of the insurer’s contact information, a toll-free number run by the warrantor, and a plain-language eligibility statement tying benefits to the customer’s having comprehensive insurance and an antitheft device.

If the product is a body-part marking product for catalytic converters, the seller must give a separate bold, 12-point written notice explaining that the customer is not obligated to purchase the product and referencing Vehicle Code section 24020.Definitions matter: the bill defines both “warrantor” and “vehicle protection product” broadly to include alarm systems, etching, locks, kill switches, tracking devices, and physical devices to prevent catalytic-converter removal. The insurance commissioner gets enforcement authority (including stop orders under Section 12921.8), and the warrantor bears the evidentiary burden of proving that a properly filed claim is not covered or that a settlement satisfied the warranty terms.

The statute carves out manufacturers and distributors of motor vehicles and excludes warranties that only promise repair or replacement after a breakdown.Operationally, the combination of insurer backstop, direct-claim language, and tight filing and cancellation rules creates new workflow and capital requirements for warrantors and specific exposure for insurers who underwrite these policies. For consumers, the statute standardizes what they must be told and gives a route to payment if a warrantor becomes insolvent or refuses to pay; for regulators, it creates a framework to police mislabeling of insurance products as warranties.

The Five Things You Need to Know

1

The insurer-backed policy must cover 100% of the warrantor’s obligations and allow a warrantyholder to claim directly from the insurer if the warrantor fails to pay within 60 days of a complete proof-of-loss.

2

A warrantor may have only one active insurer policy on file with the insurance commissioner at any time; if an insurer cancels, the warrantor must either file a replacement policy before termination or stop acting as a warrantor.

3

Warranties must include two required, conspicuous disclosures in at least 10-point type: one saying ‘This agreement is a product warranty and is not insurance’ and another saying the warrantyholder must have comprehensive coverage and an antitheft device to be eligible.

4

If the product covers only a catalytic converter, benefits are capped at the actual cost of replacing the catalytic converter; body-part marking sellers must provide a separate 12-point bold notice stating the buyer is not required to purchase the protection and referencing Vehicle Code §24020.

5

The bill shifts the evidentiary burden to the warrantor: the warrantor must prove a compliant claim is not covered or that a settlement satisfied the warranty, and the commissioner may issue a stop order for violations.

Section-by-Section Breakdown

Every bill we cover gets an analysis of its key sections. Expand all ↓

Section 116.6(a)(1)

Admitted-insurer backstop, filing, and cancellation rules

This subsection requires warrantors to maintain a policy with an admitted insurer that covers 100% of the warrantor’s obligations and to file that policy with the insurance commissioner. Practical implications include a single-active-policy limit, protections preventing insurer defenses tied to the warrantor’s administrative failures, and prescriptive cancellation notice periods (30 days generally, 10 days for fraud/misrepresentation). If an insurer cancels, the warrantor must either replace the policy without a coverage lapse or stop offering warranties, a requirement that forces continuous coverage or market exit.

Section 116.6(a)(2)

Prohibition on using insurance-like trade terms

The bill bars warrantors from using terms like ‘insurance,’ ‘casualty,’ ‘surety,’ or any deceptively similar wording in the product name, warranty, advertising, or materials. That protects consumers from mislabeling, but it also requires marketers and compliance teams to audit product language and promotional material to avoid regulatory action.

Section 116.6(a)(3)–(5)

Eligibility, benefit limits, and required written disclosures

Warranties are limited to customers who already carry comprehensive vehicle insurance, and benefits are narrowly defined: for vehicle-level products, reimbursement is limited to the difference between actual cash value and replacement cost, rental costs, deductible reimbursement, and registration fees/taxes or a fixed benefit; for catalytic-converter-only products, benefits are limited to replacement cost. The warranty must be written and contain specific statements (direct-claim right against the insurer, insurer contact info, toll-free number, eligibility rule, and two mandatory 10-point disclosures). Sellers must also provide a distinct, bold 12-point notice for certain body-part marking products.

Section 116.6(b)

Definitions of warrantor and vehicle protection product (including catalytic-converter devices)

This subsection defines the key terms and intentionally casts a wide net: vehicle protection products include alarms, etching, steering locks, kill switches, tracking devices, and any device or service designed to prevent catalytic-converter removal. The broad definition captures many aftermarket products and ties the statute’s coverage and disclosure rules to those categories, making it unlikely that a seller can avoid the statute by minor product tweaks.

Section 116.6(c)–(d)

Enforcement power and burden of proof

The insurance commissioner may issue stop orders under Section 12921.8 for violations, giving regulators a direct remedy to halt noncompliant activity. The bill also places the burden on the warrantor to prove that a compliant claim is not covered or that any settlement satisfied the warranty, reversing the usual initial presumption in favor of the consumer and creating litigation and documentation requirements for warrantors.

Section 116.6(e)–(f)

Exclusions and litigation carve-outs

The statute excludes motor vehicle manufacturers and distributors and excludes warranties that only provide repair or replacement after mechanical or electrical breakdown of the protection product. It also clarifies that nothing in the section is intended to affect pending litigation, which preserves existing court disputes while the statutory regime applies prospectively.

Who Benefits and Who Bears the Cost

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.

Who Benefits

  • Consumers with comprehensive auto insurance — They gain a standardized set of disclosures, a clear eligibility rule, and a direct claim route against an insurer if a warrantor fails to pay after 60 days.
  • Regulators (insurance commissioner) — The statute gives the commissioner filing visibility into policies backing warranties and a stop-order tool to halt noncompliant warrantors quickly.
  • Buyers of catalytic-converter protection products — They receive clearer terms and explicit benefit caps (replacement cost for converters), reducing surprise outcomes and making cost-benefit calculations easier.

Who Bears the Cost

  • Warrantors and third‑party sellers — They must purchase admitted-insurer coverage that fully backs their obligations, maintain continuous filed coverage, and implement specified disclosures and call centers, increasing operating and insurance costs.
  • Admitted insurers writing these policies — They face direct-claim exposure and non‑negation language that limits defenses tied to warrantor administrative failures, which can increase underwriting risk and pricing pressure.
  • Auto dealers and point-of-sale staff — Dealers must provide separate bold disclosures for certain products and ensure customers understand eligibility tied to comprehensive insurance and antitheft devices, adding compliance steps and potential sales friction.
  • Consumers without comprehensive coverage — They are excluded from eligibility under the statute, which may reduce availability of warranty benefits for lower‑income drivers who lack full coverage.

Key Issues

The Core Tension

The central tension is between consumer protection and market viability: the bill provides stronger consumer remedies and an insurer backstop while stripping these products of insurance status (and some insurance regulatory features). That reduces regulatory complexity for sellers but increases their cost of doing business and creates direct legal exposure for insurers—forcing a trade-off between clearer consumer recovery paths and higher compliance and underwriting costs that could constrict the market.

The bill marries two conflicting regulatory aims: protect consumers by requiring an insurer backstop and clear disclosures, while preserving a non‑insurance market for protection products. That hybrid creates practical questions.

First, admitted insurers that underwrite these warranties will face direct claims and statutory limits on defenses tied to warrantor conduct; insurers may react with higher premiums, tighter underwriting, or refusal to insure certain warrantors, shrinking market supply. Second, the single-policy filing rule and cancellation mechanics reduce complexity but concentrate risk: losing one insurer equals immediate market exit unless a seamless replacement exists.

Implementation details also matter and are unresolved by the text. The statute mandates a 60-day window before a direct claim but does not define ‘complete proof-of-loss’ beyond the warranty language, leaving room for disputes about when the clock starts.

The eligibility tie to ‘comprehensive insurance’ and an ‘antitheft device’ raises definitional questions—are required coverages or device standards uniform across insurers and sellers? The separate 12-point bold disclosure referencing Vehicle Code §24020 clarifies dealer obligations but may confuse consumers about what is required versus optional.

Finally, shifting the evidentiary burden to warrantors improves consumer collection prospects but invites increased litigation over claim compliance and settlement sufficiency, which could burden courts and regulators.
