What should Model S owners do about recall 21V846?

Check your VIN, schedule the free recall repair, and keep a repair order for every dealer visit.

  1. Check your VIN at nhtsa.gov/recalls to confirm recall 21V846000 applies to your Model S.
  2. Book the recall appointment with any authorized Tesla dealer. Ask up front whether parts are available and how long the vehicle will be there.
  3. Keep a copy of every repair order. Check that each one lists your complaint, the mileage, and the dates in and out.
  4. Keep a simple log of any camera symptoms with dates and mileage. Video of a warning light or the problem happening is strong evidence.
  5. Count the days the vehicle is at the dealer. Days out of service add up toward California's 30-day presumption.
  6. If the recall repair does not fix it, or the vehicle keeps going back for the same issue, talk to a lemon law attorney.

What are Model S owners reporting to NHTSA?

Owners have filed 1,963 complaints with NHTSA about these vehicles since 2020, 304 of them about the driver assistance.

Since recall 21V846 was reported on October 29, 2021, owners have filed 280 complaints with NHTSA about the driver assistance on these vehicles. 63 of them (22%) describe the same problem happening more than once or coming back after a repair attempt.

How we counted: we matched NHTSA owner complaints for the model years in this recall that list the driver assistance and were received on or after October 29, 2021, then flagged narratives that describe a repeat failure or a problem returning after a dealer repair, recall service or software update. Data from NHTSA, accessed October 1, 2026. Complaints are unverified owner reports and may involve a related driver assistance issue rather than this exact defect; automated text matching can miss or misread some reports.

NHTSA’s public complaint database lists 1,963 owner complaints filed since 2020 for the vehicles in this recall, and 304 of them involve the driver assistance. Complaints are reports from owners and have not been verified by NHTSA, but a high count for the same component is a sign the problem is widespread.

  • 2021 Tesla Model Y: 1,079 complaints in total, 160 about the driver assistance
  • 2021 Tesla Model 3: 664 complaints in total, 125 about the driver assistance
  • 2021 Tesla Model S: 179 complaints in total, 15 about the driver assistance
  • 2021 Tesla Model X: 41 complaints in total, 4 about the driver assistance

Can recall 21V846 make my Model S 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.

A recall by itself does not make a car a lemon. Under California's Song-Beverly Consumer Warranty Act, what matters is whether a defect covered by the warranty substantially impairs the vehicle's use, value or safety, and whether the manufacturer or its dealers fixed it within a reasonable number of attempts (Civ. Code 1793.2(d)).

Driver assistance systems such as automatic emergency braking, lane keeping and adaptive cruise rely on software and sensors. Phantom braking or a system that shuts off can be dangerous, and these complaints often return after an update.

This recall is handled by an over-the-air software update, so many owners never visit a dealer. If the problem returns after the update, take the 2021 Tesla Model S to the dealer and make sure the visit is written up on a repair order. An update that does not work is still a failed repair.

Civil Code 1793.22(b) sets out a presumption that applies in the first 18 months or 18,000 miles: two or more repair attempts for a defect likely to cause death or serious bodily injury, four or more attempts for the same defect, or more than 30 total days out of service for repairs. Written notice to the manufacturer is required in some cases. Owners outside that window can still have 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.

A software update can count as a repair attempt, especially if you complained about the problem or the update keeps being repeated. I've seen dealers do the same software update five or six times with no 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 21V846

Did the recall 21V846 fix work?

Since recall 21V846 was reported on October 29, 2021, owners have filed 280 complaints with NHTSA about the driver assistance on these vehicles. 63 of them (22%) describe the same problem happening more than once or coming back after a repair attempt. If your vehicle still has the problem after the recall repair, go back to the dealer, get a repair order, and talk to a lemon law attorney.

Is the 21V846000 recall repair free?

Yes. Safety recall repairs are done free of charge at authorized dealers.

How do I know if my Model S is part of recall 21V846000?

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.
