Documentation
Documenting Your Case
A lemon law claim without documentation is just a complaint. With documentation, it's a case. Start keeping records from the first repair visit — before you know you'll need them.
The core principle
Manufacturers and dealers have legal teams whose job is to find gaps in your record. Every missing repair order, every verbal-only conversation, every undated photo is a gap they will exploit. Your job is to create a paper trail so complete that there's nothing to dispute.
Start now, even if you're not sure you have a lemon. Records are easy to create in the moment and impossible to recreate later. A repair order from two years ago that you didn't keep is gone.
Repair orders: the most important document
Every time you bring your vehicle in for a defect-related repair, you must get a written repair order. Do not leave the dealership without one. The repair order should include: the date you brought the vehicle in, the date you picked it up, the mileage at drop-off, your description of the problem in your own words, the dealer's diagnosis, what work was performed, and whether the problem was reproduced.
Read the repair order before you sign it. If the dealer writes 'no problem found' or 'could not duplicate,' ask them to add your description of the symptoms. If they refuse, write it yourself in the customer comments section and keep a copy. 'No problem found' is not the same as 'no defect exists' — it just means they didn't find it that day.
Keep every repair order, even for unrelated work. It establishes a timeline and shows the vehicle's overall service history.
Days out of service
Many state lemon laws count the total number of days your vehicle is out of service for warranty repairs. Track this carefully. The clock typically starts when you drop the vehicle off and stops when it's available for pickup — not when you actually pick it up.
Keep a log: date in, date available, date picked up, mileage, reason for visit. A simple spreadsheet works. If you hit 30 cumulative days in most states, you've met one of the lemon law thresholds regardless of how many separate repair attempts there were.
Written communications
Never rely on verbal conversations with the dealer or manufacturer. Follow up every phone call with an email: 'Per our conversation today, you confirmed that the transmission issue I reported on [date] has not been resolved and requires another repair attempt.' This creates a record the other side can't later deny.
When you escalate to the manufacturer's customer service line, get a case number. Ask for the representative's name and ID. Send a follow-up email to the address they give you summarizing what was discussed and what was promised.
Photos and video
Photograph warning lights on your dashboard the moment they appear. Video the symptom if it's safe to do so — a transmission shudder, an unusual sound, a warning message. Your phone's camera timestamps photos automatically; don't edit or reprocess them, as that can strip the metadata.
Photograph the odometer at each repair visit. Photograph any visible damage or fluid leaks. Store everything in a dedicated folder, backed up to cloud storage.
What to send to an attorney
When you consult a lemon law attorney, bring: all repair orders in chronological order, your purchase or lease agreement, the manufacturer's warranty booklet, any written communications with the dealer or manufacturer, your NHTSA complaint confirmation number if you filed, and your days-out-of-service log.
A good lemon law attorney will review this for free. They work on contingency — they only get paid if you win, and the manufacturer pays their fees under Magnuson-Moss. You should not have to pay out of pocket.
