Mercedes Battery Drain Failures

On July 1, 2022, Lieff Cabraser and co-counsel filed a federal automotive defect lawsuit in Georgia district court against Mercedes-Benz USA LLC and Daimler AG alleging breach of warranty, violation of state and federal consumer fraud laws, fraudulent concealment and unjust enrichment relating to sudden total car battery failures in 2004-2022 models across the Mercedes-Benz vehicle line, including Class S, C, A, CLA, CLS, G, GLA, GLK, GLC, ML, GLE, GL, GLS, and E vehicles that Mercedes manufactured between 2004 to 2022.

Reports cited in the Complaint include sudden drastic battery failures including in Class S, Class C, Class G, GLE (once Class M), and Class E vehicles. Owners and lessees across the U.S. report leaving their cars for several hours without any lights or electronics on, only to return and find the Mercedes car battery completely drained. As the Mercedes-Benz battery drains can occur without warning, drivers may be unexpectedly stranded and placed in perilous situations. They also report having to repeatedly pay out-of-pocket for costly diagnostics, software updates, and battery replacements, none of which remedy the problem. These complaints date as far back as 2004, and continue through 2020 model year MB vehicles.

The lawsuit seeks declarative and injunctive relief, including that Mercedes reassess all prior warranty claims related to the battery drain defect, to refrain from further deceptive distribution, sales, and lease practices with respect to the affected vehicles, to pay inspection and repair/replacement costs, and disgorgement of all or part of the ill-gotten revenue it received from the sale or lease of the affected vehicles or make full restitution thereof to plaintiffs and the putative class.

A second defect has been alleged relating to Mercedes-Benz vehicles with 48V/12V battery hybrid systems. The defect causes vehicles to shutoff, overheat, go into limp home mode, or lose acceleration at highway speeds. This defect is said to affect 2019-2021 model year Mercedes-Benz vehicles including GT-Class, GLS-Class, GLC-Class, C-Class, CLS-Class, E-Class, and GLE-class M-B hybrids.
