Mercedes-Benz electrical drain defect class action overview: 

  • Who: A group of Mercedes-Benz drivers are suing the automaker.
  • Why: The plaintiffs say a number of Mercedes vehicles have a defect that causes the battery to drain “rapidly and unexpectedly.” 
  • Where: The lawsuit was filed in a New Jersey federal court.

A broad swath of Mercedes-Benz vehicles made between 2004 and 2022 have a defect that causes the batteries in the vehicles to drain “rapidly and unexpectedly,” a new class action lawsuit alleges.

Plaintiffs Lewis Young, Enrique Perez, Merissa Jones, Valeriu Matei, Teresa Isom, Linda Blackwell, Kia Watson, Muhammed Jackson, Levanda Gayden, Jackie Rasmussen, Siro Brenes, Carl Clark, Andrea Geoly and Keith Colwell filed the class action complaint against Mercedes-Benz USA LLC and Daimler AG Sept. 12 in a New Jersey federal court, alleging violations of state and federal consumer laws. 

This lawsuit arises out of a defect that causes the battery in Mercedes vehicles to suddenly drain, the plaintiffs say.

According to the plaintiffs, the defect arises from a common electrical system used across vehicles manufactured between 2004 and 2022, including but not limited to Mercedes Class S, C, A, CLA, CLS, G, GLA, GLK, GLC, ML, GLE, GL, GLS and E vehicles.

“In all vehicles, the [defect] causes the battery to suddenly drain, preventing the car from starting, potentially stranding the occupants and endangering their safety,” the plaintiffs alleges.

As a result, the cars are unsafe, unreliable and undesirable, the plaintiffs say.

Mercedes knew about defect but didn’t fix it, lawsuit alleges

Based on customer complaints, repair data, and other internal sources, Mercedes knew or should have known about the existence of the defect and its consequences, the Mercedes-Benz lawsuit alleges.

“Nevertheless, Mercedes has never offered to repair the Electrical Drain Defect or otherwise compensate Class Members for their injuries resulting from the defect which it has not repaired,” it says. 

Mercedes continues to market its vehicles as safe and reliable, leaving purchasers to carry the costs of dealing with the defect, the plaintiffs state.

As a result, plaintiffs overpaid for their vehicles and had expenses related to the flaw, they say. 

They’re looking to represent anyone who purchased or leased a Mercedes vehicle containing the electrical drain defect rendering them subject to any remedial- or counter-measure.

The plaintiffs are suing for fraudulent concealment, unjust enrichment, breach of warranty, breach of fair dealing and breaches of state consumer laws. 

They are seeking certification of the class action lawsuit, an injunction forcing Mercedes to treat the problem, restitution, damages, fees, costs and a jury trial. 

Meanwhile, in July, Mercedes-Benz agreed to a class action lawsuit settlement to resolve allegations its interior Burl Walnut trim is defective and can fade.

    I have a 2005 E320 wagon and have been having battery issues for a while.I think I am on my 4th battery due to continuous charging. My car has been in the shop for 4 weeks this latest time and I think the bill is over $3000.Now after talking to a MBZ Shop Forman he is recommending replacing the seat controller unit.Since I have had this car I have replaced SAM units,Bus Units and now the seat controllers.
    I would love to get some money back .This car has had multiple issues with Fuel pumps (2) failed Catalytic Converters etc.My recommendation is do not buy a Mercedes newer than 2002. My Wifes car has run flawlessly for over 150k miles.

    I am inquiring about a class action law suite that is still underway? We have been dealing with the battery issue with our 2020 Mercedes for over a year and half. Right now it’s parked in our garage and is totally non operational. No electrical system what so all and this is a car that cost us slightly under $200k. It’s had the original battery and one replacement. We have been mislead multiple times about battery replace and just found out about the class action suits.

  5. Fabrenia Favors says:

    What about those of us who purchased a used Mercedes and the battery continues to stay dead and the dealership continued to say it was other things that needed to be repaired and eventually I just ended up doing a voluntary repo because the 2014 E350 Mercedes’ continued to cause me serious issues.
