California Lemon Law & Auto Fraud Rights

California’s Lemon Law protects buyers and lessees when a motorhome or RV spends significant time in the shop or the same defects recur after reasonable repair attempts. The law applies statewide, including in Pomona and Colton.

Repurchase or replacement when defects substantially impair use, value, or safety.
Reimbursement for incidental costs – towing, rental, registration.
Recovery of attorney’s fees from the manufacturer if you prevail.

California Lemon Law – Common Questions

How many repair attempts are “enough” in California?

There’s no single magic number. Repeated attempts for the same defect—or extended time out of service—can support a California Lemon Law claim, especially when the problem substantially affects use, value, or safety.

Does California Lemon Law apply to motorhomes and RVs like a Thor A.C.E.?

Often, yes. Many motorhome disputes involve warranty-covered defects and repeated repair attempts documented on service records. Eligibility depends on the facts (what failed, who provided the warranty coverage, and the repair history), so the most reliable starting point is a document review.

What if my motorhome’s water heater won’t ignite - or hot water keeps failing - after repairs?

When the same hot-water/water-heater problem keeps returning after warranty repair attempts, it can be a strong indicator of a repeat-defect pattern. The key is documenting each visit (dates, mileage, complaint, what was replaced/adjusted, and whether the issue actually stayed fixed).

Does my city (e.g., Pomona) matter for a Lemon Law case?

No. California Lemon Law protections are statewide. Your city typically matters for practical reasons (where repairs occurred and where the vehicle is located), not whether you have rights under California law.
