- Electrical and power-system complaints documented early (generator/solar/shore-power/step/battery-related issues).
- Fit-and-finish and hardware problems (doors/drawers/trim/screen/window items opening or failing in transit).
- Water intrusion/leak allegations documented in connection with water-heater-area complaints.
Recalls & Common Complaints (2018 Thor A.C.E. 32.1)
Recall campaigns are often VIN-specific. If you’re seeing similar symptoms, a quick VIN recall check can confirm whether your Thor A.C.E. 32.1 is included.
- Some Thor Motor Coach motorhomes from this era had recall activity involving LP/propane system components (fire risk).
- Some Thor Motor Coach motorhomes from this era had recall activity involving exterior/trailer lighting wiring, which could affect lighting visibility.
Settlement Outcome
Without admitting liability or wrongdoing, the case resolved through a California Lemon Law repurchase, with the manufacturer buying back the motorhome and paying the owner $140,590.98 as a single total payment to end the dispute under California law.
The settlement stated it was not an admission of liability.

California Lemon Law & Auto Fraud Rights
California’s Lemon Law can apply when a warranted vehicle has substantial defects that persist after reasonable repair opportunities, or when the overall warranty-repair history shows an ongoing inability to conform the vehicle to warranty.
For motorhomes, coverage can still be meaningful even when different components have different warranty responsibility (for example, coach systems versus chassis-related systems). The service timeline and repair orders are typically the backbone of proving the pattern.
- Repeat repair attempts for the same system (e.g., water heater) can support a claim.
- Safety/drivability and water-leak issues can be material because they affect use, value, and safety.
- Documentation matters: dates, mileage, and repair narratives establish the pattern.
- Statewide protection: California Lemon Law is statewide; Upland primarily localizes where the consumer is based and where service activity occurred.
California Lemon Law – Common Questions
How many repair attempts are “enough” in California?
There is no single magic number. Repeated attempts for the same substantial defect—or a pattern showing the problem persists—can qualify.
Does California Lemon Law cover motorhomes and RVs?
Yes. Motorhomes can qualify, but responsibility can vary by component (coach systems vs. chassis systems). Your repair orders help clarify which defects were addressed and whether the pattern persisted.
Does my city matter (Upland)?
No. Protections are statewide in California; Upland primarily helps localize where the consumer is based and where service activity occurred.
What should I gather for a free case review?
Bring your purchase/finance paperwork (if available) and all repair orders/invoices showing dates, mileage, complaints, and what was done. A clean timeline is often the fastest way to evaluate eligibility.
Next Steps
If your RV keeps going back for the same system failures—especially water intrusion, electrical problems, or warranty runaround—do not wait. Deadlines can apply under California law, and early documentation review can materially improve outcomes.
