Migliaccio & Rathod LLP is investigating Dyson V11 & V15 series cordless vacuums for premature battery failure, misleading run-time claims, and costly replacement batteries that may leave consumers paying far more than they expected for “premium” devices.
Reported Issues
Purchasers report that Dyson’s advertised “up to 60 minutes” of run time quickly collapses within 12–18 months of normal use. Common consumer complaints include:
- Batteries dropping from 45–70 minutes to single-digit minutes
- Vacuums shutting off abruptly at high power modes
- Batteries dying weeks after the 2-year warranty expires
- OEM replacement batteries costing $120–$150—roughly 25% of a new vacuum
- Users calling for a class action due to uniform early battery degradation
These issues appear distinct from Dyson’s pending California lawsuit regarding warranty start dates, suggesting a separate theory surrounding battery longevity and misrepresented life-cycle expectations.
Why Consumers Should Be Concerned
If Dyson knew that its batteries degrade far sooner than advertised, this may violate:
- State UDAP statutes prohibiting deceptive durability or run-time claims
- Magnuson–Moss Warranty Act for warranty breaches
- Implied warranty of merchantability, where vacuums fail prematurely
- Unconscionable replacement-parts pricing that forces consumers toward costly upgrades
Consumers may have overpaid for vacuums marketed as long-lasting and high-end when the batteries provide only a fraction of the expected lifespan.

- Were denied warranty coverage or told the failure was “normal wear”
