California's Song-Beverly Act does not require infinite patience. The statute creates a presumption in your favor at two, four, or thirty days, and even outside those numbers a vehicle can qualify as a lemon. Here is the full rule, without the marketing-copy simplifications.
California Civil Code section 1793.22(b) creates a statutory presumption that the manufacturer has had a reasonable number of repair attempts. When the presumption applies, you do not have to prove that the repair opportunities were enough; the law treats them as enough unless the manufacturer disproves it.
The presumption applies when, within 18 months of delivery or 18,000 miles (whichever occurs first), any of these happen:
Those three branches are disjunctive. Meeting any one of them triggers the presumption. Most clients hit the four-attempt branch first, but the 30-day branch is often the sleeper: a vehicle can be "in the shop" far longer than owners realize once parts delays and loaner periods are added up.
The two-attempt branch applies to any nonconformity likely to cause death or serious bodily injury. California courts have treated the following as safety defects qualifying for the two-attempt trigger:
The statute does not require the defect to have actually caused an injury. It requires only that the defect be "likely to cause" death or serious bodily injury. That is a risk test, not an outcome test.
For non-safety defects, the presumption kicks in at four attempts for the same nonconformity. This is the most commonly triggered branch and also the one manufacturers most often dispute by arguing the complaints were different issues, not the same one. Good documentation wins that argument. When every repair order lists the same customer concern, even if the dealer tech used different fault codes or described the root cause differently each time, the nonconformity is the same under Oregel v. American Isuzu Motors, Inc. (2001) 90 Cal.App.4th 1094 and later cases.
Any calendar day the vehicle sits at a dealership for warranty repair counts. Days waiting on back-ordered parts count. Days the tech never touched the car because another bay was free count. Days in a holding lot while the dealer waits for the manufacturer to approve authorization count. The only exclusion is time outside warranty repair, such as collision repair the dealer happens to be doing simultaneously.
Owners of diesel pickups, heavy SUVs, and EVs with drive-unit replacements frequently hit the 30-day branch first because replacement components are back-ordered. Keep rental car receipts and loaner agreements with dates; they prove the calendar days.
A repair attempt is any time you present the vehicle to the manufacturer or its authorized representative for repair of a warrantable defect. It includes:
A could-not-duplicate or CND entry still counts. Under Civil Code 1793.2(b), the manufacturer has the obligation to diagnose and repair. You do not lose a repair attempt because a technician could not reproduce the defect on a short test drive.
If you are at four attempts, two attempts on a safety defect, or 30 cumulative days out of service, the manufacturer presumptively owes you a buyback, replacement, or cash settlement. The manufacturer pays your attorney fees under Civil Code 1794(d).
The presumption does not apply outside 18 months or 18,000 miles, but the underlying right does. Civil Code 1793.2(d)(2) requires a buyback whenever the manufacturer has been unable to conform the vehicle after a reasonable number of attempts. The presumption is a shortcut. Without it, the reasonableness question goes to the jury, and juries frequently find three attempts over two years unreasonable if the defect is severe and the manufacturer was obviously not progressing toward a fix.
Can I file on just three attempts?
Often yes, especially if the defect is safety-critical or the car has been out of service for weeks. Call before assuming the number is too low.
Do recall repairs count toward the 30-day branch?
Generally yes, if the recall relates to a nonconformity you have complained about.
What if the dealer never opened a repair order?
Request the invoice in writing. If the dealer refuses to document your complaint, that is itself a violation of Civil Code 1793.2(b).
Free consultation. No fee unless we win. Manufacturer pays your attorney fees under Civil Code 1794(d).
