When your car spends more time in the shop than in your driveway, it’s natural to wonder how much time you have to claim a lemon. In California, deadlines matter. Understanding the statute of limitations and when the clock starts can make the difference between a successful claim and a missed opportunity. Below, ZapLemon explains the key timing rules in plain language so you can protect your rights without the legal jargon.
California Lemon Law Statute of Limitations
In California, most lemon law lawsuits under the Song-Beverly Consumer Warranty Act must be filed within four years. That “statute of limitations” typically runs from when the warranty was breached—often when the manufacturer failed to fix the vehicle after a reasonable number of attempts or refused to repurchase or replace it. While four years is a helpful rule of thumb, specific facts can shift when that four-year period begins, so timing should be assessed carefully.
There are different timing rules for different warranty claims. For example, claims based on the implied warranty of merchantability (the basic promise that a new car is fit to drive) also carry a four-year filing deadline, but the clock often starts at delivery because the implied warranty is tied to the sale. Importantly, the implied warranty’s duration is at most one year for new vehicles, but a defect that shows up later can still relate back to a problem that existed at delivery. Used cars may be covered if they’re sold with the manufacturer’s new car warranty still in effect, but details matter.
There can be exceptions that pause or affect the deadline, such as when a manufacturer conceals a defect, during certain class actions, or in rare circumstances involving arbitration or repair promises. These are fact-specific and not automatic. The safest practical step is to act early: document repairs, keep your timeline straight, and consult a professional to evaluate how the statute applies to your situation.
When Does the Clock Start? Repairs and Notices
A common question is when the lemon law “clock” starts ticking. In many cases, it begins when you knew or should have known that the manufacturer could not or would not repair the vehicle to conform to the warranty—often after a reasonable number of repair attempts or a clear refusal to repurchase or replace. That means the start date is not necessarily the day you bought the car; it may be later, tied to the repair history and the manufacturer’s responses.
Your repair visits are key evidence. Keep every repair order, note the dates, mileage, and symptoms (stalling, brake problems, electrical failures, repeat check-engine lights), and track days out of service. California’s “lemon law presumption” helps if, within the first 18 months or 18,000 miles, you’ve had multiple repair attempts for the same safety defect, four or more attempts for a non-safety defect, or 30+ total days out of service. You can still have a valid claim even if you don’t meet the presumption; it just provides a helpful shortcut.
Notices can also affect timing and proof. Some warranties ask owners to contact the manufacturer directly (not just the dealership) to request a final repair or repurchase—check your warranty booklet for any written notice steps. If you send a letter or email, keep copies and delivery confirmations. Promptly notifying the manufacturer and continuing to take the vehicle to an authorized facility can show you gave a reasonable opportunity to repair, which is central to a California lemon claim.
