Documenting Evidence for a Maryland Lemon Law Claim
How to document repair attempts, OOS days, and defect history for Maryland BBB Auto Line IDS or court action.
Documentation is the foundation of every Maryland Lemon Law case. The 24-month / 18,000-mile Rights Period requires consistent, well-documented ROs.
What to document
1. Repair orders (the most important documents)
Every visit to the manufacturer-authorized service facility must produce a written repair order (RO). Each RO must contain:
- Date of vehicle drop-off and pickup.
- Mileage at drop-off and pickup.
- Customer complaint in your own words.
- Technician findings and work performed.
- Parts replaced.
- Authorized dealer name.
- VIN.
Insist on receiving a printed RO at every visit.
2. OOS day tracking — calendar days
For the 30-day threshold, track every day the vehicle is at the dealer (calendar days, includes weekends and holidays):
| RO# | Drop-off | Pickup | Days OOS | Reason |
|---|---|---|---|---|
| 12345 | 6/2 | 6/8 | 6 | Transmission diagnosis |
| 12678 | 7/14 | 8/15 | 32 | Waiting parts |
3. Written communications
Save copies of:
- Email correspondence with dealer service manager.
- Text messages with service advisor.
- Letters to/from manufacturer’s customer relations.
- BBB Auto Line filings if any.
4. Manufacturer customer-relations case file
Manufacturers open a customer-relations case when you escalate. Demand a written case summary.
5. Photos and video
- Defect manifestation (dashboard lights, fluid leaks, paint defects).
- Repair-shop intake photos.
- Driving-condition video.
6. Diagnostic data
For Tesla / EV cases, request the diagnostic logs. Most manufacturers maintain telematics records.
Common documentation mistakes
- Going to independent mechanics — repairs don’t count toward Lemon Law thresholds.
- Vague RO descriptions — describe symptoms specifically.
- No printed RO — demand one anyway.
- Inconsistent complaint language — describe the same symptom the same way at each visit.
Maryland-specific considerations
- Multi-county travel — Maryland plaintiffs may visit dealers in different counties; any authorized dealer counts.
- Coastal corrosion documentation — for Eastern Shore / Chesapeake Bay vehicles, distinguish defect from salt-air corrosion.
- DC-area registration — vehicles registered in DC but purchased in MD may face jurisdictional questions.
- Federal-employee documentation discipline — federal employees often maintain meticulous records that strengthen cases.
Bottom line
The repair orders and OOS day tracking ARE the case. Maryland’s 24-month / 18K window provides reasonable time, but every day counts. Get a printed RO every visit, and keep them all.
