- Call a Mercedes-Benz dealer and schedule the recall repair. Ask how long the repair takes and whether parts are in stock.

- 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.

Complaints are unverified owner reports and may involve a related ev and hybrid battery issue rather than this exact defect; automated text matching can miss or misread some reports.

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.

Can recall 24V331 make my EQB 300 4MATIC 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 EQB 300 4MATIC 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 2022 Mercedes-Benz EQB 300 4MATIC 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.
A remedy is available. Many vehicles are fixed on the first try. If the problem returns after the recall repair, or the 2022 Mercedes-Benz EQB 300 4MATIC has needed other repairs for the same defect, those visits count toward a lemon law claim.
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.
Recall repairs depend on parts. Owners can wait days, weeks or months, usually about one to three months in our cases, and those days count toward California's 30-day out-of-service rule.
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 24V331
Did the recall 24V331 fix work?
Since recall 24V331 was reported on May 10, 2024, owners have filed 16 complaints with NHTSA about the ev and hybrid battery on these vehicles. 1 of them (6%) describe the same problem happening more than once or coming back after a repair attempt.

Is the 24V331000 recall repair free?
Yes. Safety recall repairs are done free of charge at authorized dealers.
How do I know if my EQB 300 4MATIC is part of recall 24V331000?
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.
Can a battery recall reduce my EV's range?
Some battery recalls limit the state of charge or range until a module or pack is replaced. Check your owner letter for any interim limits, and keep notes if range or charging changes after the repair.
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.
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.
