Can recall 22V155 make my S6 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 22V155000 does not automatically make your S6 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))?

Fuel pump and fuel line defects can cause the 2021-2022 Audi S6 to stall without warning. If it happens again after the recall repair, document it and return to the dealer.

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.
