3. 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.
4. Keep a simple log of any propulsion system symptoms with dates and mileage. Video of a warning light or the problem happening is strong evidence.

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 AMG S 63 E owners reporting to NHTSA?

Too few NHTSA complaints about the ev and hybrid battery have been filed since recall 25V129 was reported (0) to say whether the fix is holding.

Can recall 25V129 make my AMG S 63 E 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.

Owners often ask whether this propulsion system recall means their AMG S 63 E qualifies as a lemon. Not by itself. Song-Beverly looks at whether a defect covered by the warranty substantially impairs use, value or safety and was not fixed after a reasonable number of repair attempts (Civ. Code 1793.2(d)).

Battery and electric drive repairs are among the slowest repairs in the industry. A 2023-2024 Mercedes-Benz AMG S 63 E waiting on a battery module or drive unit can sit at the dealer for weeks, and every day counts toward the 30-day figure in California's lemon law presumption.

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.
