Mercedes-Benz EQS Lemon Law Attorney

Abnormal or premature battery degradation that substantially impairs your EQS's usability is covered under the Song-Beverly Act as a warranty defect. Normal gradual degradation over years is expected, but sudden drops in range or BMS errors within the warranty period indicate a defect in materials or workmanship. Mercedes-Benz offers a separate high-voltage battery warranty of 10 years or 155,000 miles, and defects during this period support a lemon law claim.

A second Hyperscreen failure after replacement demonstrates that Mercedes-Benz has been unable to conform your EQS to warranty, which is a core requirement for a Song-Beverly Act claim. The Hyperscreen is the primary interface for vehicle controls, navigation, and climate, so its failure substantially impairs the vehicle's use and value. Two repair attempts for this defect, combined with the extremely high replacement cost, create a compelling case for repurchase or replacement.

Yes, defects introduced or not resolved by OTA software updates are covered under the Song-Beverly Act. If an OTA update caused your EQS's rear-axle steering or other systems to malfunction, Mercedes-Benz is responsible for correcting the defect under warranty. Each dealer visit or OTA update attempt to address the same defect counts as a repair attempt. The fact that the manufacturer pushed a defective update can also support a claim of willful violation for civil penalty damages.

Yes, the Song-Beverly Consumer Warranty Act protects subsequent owners of vehicles still covered by the manufacturer's original new vehicle warranty. As the second owner of your EQS, you have the same lemon law rights as the original purchaser for defects that arise during the remaining warranty period. You should obtain the vehicle's complete service history from Mercedes-Benz, as prior owner repair attempts for the same defect may be combined with yours to meet the lemon law threshold.
