How Long Do I Have to File a Delaware Lemon Law Claim?
Delaware's deadlines — the warranty-or-one-year coverage window (no mileage cap), certified-IDS exhaustion, and the Consumer Fraud Act and Magnuson-Moss clocks.
Delaware’s lemon law is built around its coverage window — the warranty period or one year, whichever is earlier — with no mileage cap. See the full statute of limitations guide.
The clocks
| Claim | Period | Runs from |
|---|---|---|
| Lemon Law coverage window | Warranty period or 1 year, whichever earlier (no mileage cap) | Original delivery |
| Certified IDS | Must be exhausted before court (§ 5007) | After written notice |
| Consumer Fraud Act | Delaware general limitations | Accrual |
| Magnuson-Moss | 4 years | Tender of delivery |
The short one-year window — but no mileage cap
The defect must be reported in writing and the presumption satisfied within the warranty-or-one-year window. There’s no mileage cap, so a high-mileage driver isn’t cut off by an odometer limit — but the time window is short, so act early.
Certified-IDS exhaustion
If the manufacturer has a certified IDS, exhaust it before suing (§ 5007). It doesn’t extend the coverage window, so start early. See manufacturer arbitration.
When the Consumer Fraud Act and Magnuson-Moss matter
The Consumer Fraud Act runs on Delaware’s general limitations, and Magnuson-Moss 4 years from delivery — both outlast the lemon law’s short window, and the Consumer Fraud Act carries the mandatory treble.
Bottom line
Report the defect in writing within the warranty period or one year — no mileage cap, but a short time window. Exhaust any certified IDS, then sue, pairing the Consumer Fraud Act (mandatory treble) and Magnuson-Moss (4 years). Get a free case review.
