Your car has been back to the dealership for the same issue. Maybe twice. Maybe more. You’re not sure whether you’ve crossed the threshold yet, and you’re not sure what to do next.
That uncertainty is exactly what manufacturers count on.
California lemon law has clear lemon law criteria, but satisfying those criteria on paper isn’t enough if you haven’t documented the right things along the way. What you do in the weeks and months before you file matters just as much as reaching the lemon law criteria on the repair log.
This checklist exists to close that gap. Use it early — before problems escalate.
What the Lemon Law Criteria Actually Require
Under California Civil Code § 1793.22(b), a vehicle is presumed to qualify as a lemon if any of the following occur within 18 months or 18,000 miles from delivery, whichever comes first:
- Two or more repair attempts for a defect likely to cause death or serious bodily injury if the vehicle is driven
- Four or more repair attempts for the same recurring defect
- 30 or more cumulative days out of service due to warranty repairs
Meeting any one of these triggers the statutory presumption in your favor. The manufacturer can try to rebut it, but the burden shifts to them.
The lemon law criteria also require that the defect “substantially impairs” the vehicle’s use, value, or safety. In Krotin v. Porsche Cars North America, 38 Cal. App. 4th 294 (1995), the court made clear this is an objective standard: what a reasonable person in your position would consider a real impairment, not just an inconvenience. That matters. A recurring transmission hesitation that a dealer dismisses as “minor” may still satisfy the lemon law criteria under California law.
Your 2026 Lemon Law Checklist
These are the lemon law preparation steps that build a winnable case. Start them the first time your car goes back in for the same problem.
Step 1: Get a repair order every single time.
Every visit to the dealership must produce a written repair order, even when the technician “couldn’t replicate” the issue. Request one before you leave. That document records the date, mileage, your complaint, and what the dealer did (or didn’t do). Without repair orders, your claim has no foundation.
Step 2: Describe your complaint specifically and in your own words.
When you bring the car in, write out exactly what is happening: “The engine hesitates at highway speeds between 60 and 70 mph, particularly after 20 minutes of continuous driving.” If you say “it drives weird,” that is what the repair order will say. Vague complaints give manufacturers room to argue the defect was never clearly reported.
Step 3: Track every day your car is out of service.
Thirty cumulative days out of service is one path to meeting the lemon law criteria under Song-Beverly, and dealers don’t always count correctly. Log every drop-off date and every pickup date. Keep this record separate from your repair orders in case documents go missing.
Step 4: Document how the defect actually affects you.
Per Krotin, substantial impairment must be real and objectively significant. Keep notes on how the defect has changed your behavior: trips you avoided, safety situations you reported to the dealer, the ways you’ve had to work around the problem. This supports the impairment element of your claim and gives your attorney something concrete to work with.
Step 5: Give the manufacturer every chance to fix it.
In Jensen v. BMW of North America, Inc., 35 Cal. App. 4th 112 (1995), the court reinforced that manufacturers are entitled to a reasonable opportunity to repair the defect before a claim can proceed. Do not skip repair appointments or decline service visits. The record you are building is one of the manufacturer failing to fix the problem despite repeated attempts. That only works if the attempts are documented.
Step 6: Put every complaint in writing.
Emails, texts, and written service requests all create a paper trail. If a service advisor tells you the issue is “normal” or “within manufacturer specifications,” follow up in writing: “As we discussed on [date], you indicated the hesitation is within spec. The issue persists.” Those statements can become part of your case.
Step 7: Keep every related receipt.
Loaner agreements, rental car receipts, and tow receipts establish that the car was genuinely out of service and that you absorbed real costs. They support claims for incidental damages on top of any buyback or replacement.
Step 8: Escalate to the manufacturer directly — and document it.
The dealership and the manufacturer are not the same party. If repairs keep failing, contact the manufacturer’s customer service line and log that contact. In Donlen v. Ford Motor Co., 217 Cal. App. 4th 138 (2013), the court upheld civil penalties against Ford for willfully failing to comply with Song-Beverly after the manufacturer had been put on notice. Escalating to the manufacturer strengthens the argument that they knew about the defect and chose not to resolve it.
Why Documentation Is the Actual Case
Every step on this checklist comes back to the same point: the lemon law criteria are a threshold, but documentation is what gets you over it.
Reaching the repair attempt count or the days-out-of-service number does not automatically produce a payout. Manufacturers contest claims. They argue the defect was not the same issue each visit. They argue the impairment was not substantial. They argue the problem has been corrected. Your repair orders, your written communications, and your personal log are what close those arguments down.

The Mistake That Costs Most Drivers
Most people start tracking documentation after they have already decided to pursue a claim. By then, they have lost the first two or three repair orders, they do not have a loaner agreement, and they cannot prove how many days the car was actually off the road.
Start this checklist at the first repair attempt, not the fourth. Understanding the lemon law criteria is step one. Building the evidence of having met them is what wins.

If You Have Already Had Multiple Repair Attempts
If your car has been back to the shop three or more times for the same problem, or if it has been out of service for weeks at a time, you may already satisfy the lemon law criteria under California law. Do not wait to find out.
