What should Cayenne owners do about recall 21V318?
Check your VIN, schedule the free recall repair, and keep a repair order for every dealer visit.
- Check your VIN at nhtsa.gov/recalls to confirm recall 21V318000 applies to your Cayenne.
- Call a Porsche dealer and schedule the recall repair. Ask how long the repair takes and whether parts are in stock.
- Get a repair order for every visit, even if the dealer only inspects the vehicle. Read it before you leave and make sure your complaint is written the way you described it.
- Write down when symptoms involving the seats happen: date, mileage, speed, weather and what you felt or heard. Photos and short videos help.
- Count the days the vehicle is at the dealer. Days out of service add up toward California's 30-day presumption.
- If the recall repair does not fix it, or the vehicle keeps going back for the same issue, talk to a lemon law attorney.

Can recall 21V318 make my Cayenne a lemon in California?
Not by itself. A recall repair that fails, or repeat dealer visits for the same defect, can support a California lemon law claim.
Recall 21V318000 does not automatically make your Cayenne a lemon. California's Song-Beverly Act asks two questions: does a warranty defect substantially impair the vehicle's use, value or safety, and did the manufacturer fail to fix it in a reasonable number of tries (Civ. Code 1793.2(d))?
Door latch, seat and body structure defects can affect safety in a crash and everyday use. If the recall repair does not solve the problem, the repeat visit is part of your record.
A remedy is available. Many vehicles are fixed on the first try. If the problem returns after the recall repair, or the 2021 Porsche Cayenne has needed other repairs for the same defect, those visits count toward a lemon law claim.
For the first 18 months or 18,000 miles, California presumes the manufacturer had enough chances if the Cayenne went in two or more times for a defect likely to cause death or serious injury, four or more times for the same defect, or spent more than 30 days in the shop (Civ. Code 1793.22(b)). Direct notice to the manufacturer is required for some of these. The presumption is a shortcut, not the only path to a claim.
An owner who prevails in a lemon law case can recover reasonable attorney fees and costs from the manufacturer (Civ. Code 1794(d)). You pay nothing, win or lose. We are paid only if you win, and the manufacturer pays our fees, including in settlements. If a case is lost, our firm covers the costs.
In our cases, a recall repair visit counts as a repair attempt, and it's strongest when the owner complained about the problem before the recall came out. A recall shows the defect is real and that enough owners reported it for the manufacturer to issue a fix.
The biggest mistake I see is waiting too long. The mileage offset starts at your first repair visit for the problem, so the sooner you take it in, the better. If the problem comes and goes, take it in when it happens. You can't go back to that date later.
If you get a recall notice, call a lemon law attorney right away. You may have taken the car in for the same problem before and forgotten, or there may be other recalls related to it.

Frequently asked questions about recall 21V318

Yes. Safety recall repairs are done free of charge at authorized dealers.
When will owners be notified?
According to NHTSA, owner notification letters were or are scheduled to be mailed June 25, 2021.
How do I know if my Cayenne is part of recall 21V318000?
Enter your 17-character VIN in NHTSA's recall lookup at nhtsa.gov/recalls, or call a dealer. The VIN is on your registration, insurance card and the lower corner of the windshield.
Does a recall mean my car is a lemon?
Not on its own. A lemon law claim depends on whether a covered defect keeps coming back or keeps the vehicle out of service. A recall repair that fails, or repeat visits for the same problem, can support a claim.
What should I keep for a possible lemon law claim?
Keep every repair order, the recall owner letter, your purchase or lease contract, and notes on dates, mileage and symptoms. Make sure each dealer visit is written up, even when the dealer says it cannot find a problem.
Does the recall fixing my car mean I have no case?
Not necessarily. Even if the recall repair fixed it, you may still have a case, and a car that's a year or more old can still qualify.
Do used cars qualify for California lemon law?
We take certified pre-owned, demo and dealer vehicles. Since the California Supreme Court's Rodriguez decision in 2024, ordinary used cars generally do not qualify.
How long does a recall lemon law case take?
Recall-related cases typically resolve in one to three months from your first call. Prior results do not guarantee a similar outcome.
What does a lemon law attorney cost?
You pay nothing, win or lose. We are paid only if you win, and the manufacturer pays our fees, including in settlements. If a case is lost, our firm covers the costs.
