Documenting Evidence for an Oregon Lemon Law Claim
How to document repair attempts, OOS days, and defect history for Oregon BBB Auto Line IDS or court action.
Documentation is the foundation of every Oregon Lemon Law case. With the 1-year UTPA SOL on top of the standard Lemon Law timeline, every visit must produce a documented repair order.
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-calendar-day threshold (60 for motor homes), track every day the vehicle is out of service for repair, INCLUDING weekends and holidays:
| RO# | Drop-off | Pickup | Calendar Days OOS | Reason |
|---|---|---|---|---|
| 12345 | Mon 6/2 | Fri 6/6 | 5 | Transmission diagnosis |
| 12678 | Mon 7/14 | Fri 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.
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.
- Miscounting OOS days — Oregon counts calendar days (not business days); include weekends and holidays the vehicle is out of service.
Oregon-specific considerations
- Wildfire smoke exposure — be ready to distinguish defect from smoke-related HVAC issues.
- Coastal corrosion — for Oregon Coast vehicles, distinguish defect from salt-air corrosion.
- Mountain driving stress — Cascade Range, Mt. Hood; document defect symptoms separately from terrain-related wear.
- Multi-county travel — Oregon plaintiffs may visit dealers in different counties; any authorized dealer counts.
Bottom line
The repair orders and OOS day tracking ARE the case. Oregon counts calendar days for the 30-day OOS threshold (60 for motor homes), so track every day the vehicle is out of service — weekends and holidays included. For UTPA claims, also document the discovery date of any deceptive practice — the 1-year SOL runs from discovery.
