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 21V707000 applies to your E-Tron.
- Book the recall appointment with any authorized Audi dealer. Ask up front whether parts are available and how long the vehicle will be there.
- 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 antilock and traction control and electronic limited slip 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.

A few excerpts from owner complaints filed with NHTSA (unverified, lightly trimmed):
On five separate occasions across two separate drivers, we have experienced a partial brake failure in this vehicle. We strongly believe this to be a software defect and not a mechanical fault. On the e-Tron, the first portion of the brake pedal swing typically activates the regenerative braking.
2021 Audi E-Tron owner, OH, NHTSA complaint 11639800, filed January 31, 2025
Moisture build-up in the high-voltage electrical system through a faulty seal on the charging socket, which can cause a short circuit and significantly increase the risk of a vehicle fire. If you get a warning light saying "electrical system: fault," you should stop driving immediately, park outdoors away from structures, and not charge the vehicle.

Car turns on but won’t move. Take it to dealership as it happens for the second time and turns out the brakes are sticking to the rotors. Audi says it’s perfectly normal just put force to the accelerator. When you do that in fact, it sound like the car is about to split in half.

Can recall 21V707 make my E-Tron 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)).
If the 2021 Audi E-Tron brakes have needed more than one trip to the dealer, keep every repair order. Brake defects are treated as serious safety problems under California law.
The recall repair is available at dealers. If it works, great. If the same symptom comes back, the recall visit is one repair attempt and the next visit is another.
California law presumes a reasonable number of attempts has been made if, within 18 months or 18,000 miles of delivery, the same problem was repaired two or more times for a defect likely to cause death or serious injury, four or more times for any covered defect, or the vehicle was out of service for repairs more than 30 days in total (Civ. Code 1793.22(b)). Some of these require written notice to the manufacturer. A claim can still succeed outside that window.
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 21V707
Is the 21V707000 recall repair free?
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 September 30, 2021.
How do I know if my E-Tron is part of recall 21V707000?
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.
