Mercedes-Benz lemon law in California: warranty notice, recalls and your options

If your GLE, C-Class, EQB or Sprinter keeps returning to the dealer for the same defect, you may have a claim under the Mercedes-Benz lemon law California buyers rely on: the Song-Beverly Consumer Warranty Act. When a manufacturer and its dealers cannot fix a warranty defect after a reasonable number of attempts, the manufacturer must repurchase or replace the vehicle.

Mercedes-Benz's warranty booklet asks owners to notify the company directly in writing, points California owners to a state-certified dispute program, and contains a separate arbitration agreement. This guide explains those terms, lists documented recalls, summarizes reported cases and sets out the deadlines. It is general information as of October 2026, not legal advice, and does not suggest Mercedes-Benz vehicles are generally defective.

How California's lemon law applies to a Mercedes-Benz

Under Civil Code § 1793.2(d)(2), if the manufacturer cannot conform a new vehicle to its express warranty after a reasonable number of attempts, it must promptly replace the vehicle or make restitution, and the buyer chooses which. Restitution covers the price paid, collateral charges such as tax and registration, and incidental damages, minus an offset: the price multiplied by the miles driven before the first repair visit for the defect, divided by 120,000 (§ 1793.2(d)(2)(C)). Our lemon law buyback calculator runs that formula.

The Tanner Act presumption in Civil Code § 1793.22(b) applies within 18 months of delivery or 18,000 miles, whichever comes first. It presumes a reasonable number of attempts if a defect likely to cause death or serious bodily injury was subject to repair two or more times, the same defect was subject to repair four or more times, or the vehicle was out of service for repairs more than 30 cumulative days. The first two routes also require direct notice to the manufacturer, discussed below. A claim can also rest on fewer attempts, or on repairs after 18 months, if the number was reasonable.

If Mercedes-Benz willfully fails to meet its obligations, a court can add a civil penalty of up to two times your actual damages, and a buyer who wins recovers attorney's fees and costs (Civil Code § 1794).

Mercedes-Benz warranty terms

Mercedes-Benz's model-year 2027 warranty booklet for its electric models, published on mbusa.com, states that the New Vehicle Limited Warranty runs for "48 months or 50,000 miles, whichever occurs first." The same booklet sets the high-voltage battery warranty at 8 years or 100,000 miles for the EQB, CLA 250, CLA 350 and G 580, and 10 years or 155,000 miles for the EQE, EQS, EQE SUV and EQS SUV. Battery capacity coverage is tied to a minimum stated in amp-hours for each model. Terms differ by model year, so read the booklet for your vehicle, and ask the dealer to print the warranty start date for your VIN.

What the Mercedes-Benz warranty booklet says about notice and arbitration

• Direct written notice. The booklet says Mercedes-Benz USA "requires that you first provide us with direct written notification of any alleged unrepaired defect," to the extent the law allows, sent to the company rather than to a dealer. It lists the Customer Care Center, One Mercedes Drive, Sandy Springs, GA 30328. Under § 1793.22(b), direct notice is required for the two-attempt and four-attempt presumptions only when the manufacturer clearly disclosed that requirement in the warranty or owner's manual. Because Mercedes-Benz discloses it, send a short dated letter describing the unrepaired defect.
• A state-certified dispute program. The booklet describes a Dispute Settlement Program run by the National Center for Dispute Settlement, and says that in California the California Dispute Settlement Program applies and that you may be required to use it before asserting certain rights under § 1793.22(b). The Department of Consumer Affairs lists Mercedes-Benz among the manufacturers that participate in a state-certified arbitration program.
• A separate arbitration agreement. The booklet also contains an individual arbitration agreement with the American Arbitration Association for disputes with Mercedes-Benz USA, including warranty disputes.

What the certified program means for you: under Civil Code § 1793.22(c), when a manufacturer maintains a qualified dispute program and gave you timely written notice of it, you generally must use that program before you can rely on the Tanner Act presumption. It does not take away your right to sue. If you are dissatisfied with the decision, the presumption becomes available again, and deadlines are extended while the program handles your claim. The program is free to consumers, according to the Department of Consumer Affairs.

The separate arbitration agreement raises a different question. In the Ford Motor Warranty Cases (2025), the California Supreme Court held that a manufacturer could not use the arbitration clause in a dealer's sales contract to force lemon law claims into arbitration. An arbitration agreement in the manufacturer's own booklet is a different document, and how it applies depends on its terms. Our guide to lemon law arbitration versus a lawsuit covers the trade-offs.

Mercedes-Benz recalls you should know

A recall alone does not make a vehicle a lemon, but a recall that matches your symptom can explain your repair history, and a recall repair that does not fix the problem can become part of your claim. This is a selection from NHTSA's database, not a complete list. Check your VIN at nhtsa.gov/recalls.

Loss of drive power, brake failure, steering loss and fire risk are the kinds of problems that can bring the two-attempt safety rule into play. Our guide to brake, steering and airbag safety defects explains how that rule works, and our guide to EV battery and charging problems covers EQ-model issues in more depth.

Reported cases involving Mercedes-Benz

Most lemon law claims settle privately. These are reported rulings and settlements in cases handled by other lawyers. They are not LaCour results.

Kwan is one reason your written record matters: documentation that Mercedes-Benz knew of the defect and did not act makes good faith harder to claim. Every case is different. Past results, including those listed here, do not predict the outcome of any other case.

Building your Mercedes-Benz repair record

• Get a repair order at every visit showing your complaint, the mileage and what was done. If the dealer could not reproduce the problem, ask that it say so.
• Describe the symptom the same way each time ("loss of power, limp mode on the freeway"), so the visits read as repeat attempts on one defect.
• Save warnings. Photograph dashboard and MBUX warnings and screenshot app alerts.
• Keep every recall letter and recall invoice. If the recall repair did not cure your symptom, the next visit should say so.
• Keep your direct-notice letter and proof of mailing, plus any case number from Mercedes-Benz Customer Care.
• Track days out of service and keep towing and rental receipts.

What to do if your Mercedes-Benz keeps going back to the dealer

1. Keep taking it to an authorized dealer and keep the paper, even when the dealer says it is "operating as designed."
2. Call Mercedes-Benz Customer Care at 1-800-FOR-MERCEDES (1-800-367-6372), the number in the warranty booklet, and write down the case number and names.
3. Send the short direct-notice letter the booklet asks for. This is not the same as a lemon law demand letter.
4. Do not file a dispute program claim, sign an arbitration form or accept a goodwill deal for a release until it has been reviewed.
5. Gather your purchase or lease contract, every repair order and the warranty booklet for a free review.

Deadlines and the 2025 rules for Mercedes-Benz

Mercedes-Benz has been reported among the manufacturers that opted in to the new procedures created by AB 1755 and SB 26, according to a February 2026 report by Consumers for Auto Reliability and Safety. Confirm it on the Department of Consumer Affairs list, which can change each year.

For opted-in manufacturers, a lawsuit generally must be filed within one year after the express warranty expires and no more than six years after the vehicle was first delivered, with time added while the vehicle is in the shop for the defect and during a qualified dispute program (Code of Civil Procedure § 871.21). To seek a civil penalty, you must send a written demand at least 30 days before suing, and the manufacturer can avoid the penalty by offering a buyback or replacement within 30 days and completing it within 60 days (§ 871.24). The booklet gives a dedicated route for California pre-suit notices. Have a lawyer prepare that demand. Our guide to the 2025 lemon law changes under AB 1755 explains the rest.
