Mercedes-Benz Class Action Lawsuit Over Piston Failure Defect

Consumers filed a class action lawsuit against Mercedes Benz in the Central District of California on November 7, 2022, alleging a piston failure defect in vehicles with the M274 engine. The class action is Jamil v. Mercedes-Benz USA, LLC, 2:22-CV-08130-FLA-AFM.

The class action lawsuit alleges that certain Mercedes Benz vehicles equipped with the M274 engine suffer from a known defect that causes the pistons to fail prematurely, which the lawsuit calls “the piston defect.” The lawsuit claims the piston defect can occur without warning and cause sudden and unexpected engine failure. The class action was filed on behalf of consumers who purchased or leased their Mercedes in California.

According to a petition over a 2015 Mercedes Benz C300 filed with the National Highway Traffic Safety Administration or NHTSA, Mercedes-Benz published a technical service bulletin (communication number LI03-10P060916) regarding a faulty wrist pin resulting in knocking, clattering, and rattling noises which caused the pistons to eventually crack. According to Mercedes-Benz, “modified” wrist pins were subsequently installed in these engines.

The M274 engine is a turbocharged inline-four longitudinal engine produced by Mercedes-Benz since 2011. This engine is installed in rear-wheel-drive vehicles such as the Mercedes C-class and E-class vehicles, including turbocharged versions of the C-Class 160/180/200/250/300e and E-Class 180/200/250/300/350e.

The class action lawsuit does not indicate which model years of these Mercedes vehicles are affected by this piston defect.

Current or former owners or lessees of these vehicles should be aware that the California lemon law and other state and federal laws may force Mercedes Benz to either “buy the vehicle back” or provide further significant compensation for those experiencing this defect.

Under California’s lemon law, qualifying lemons must be bought back, and that can mean a large cash refund and payoff of your loan or lease. The refund could be as much as everything you paid for the vehicle and everything you owe: monthly payments, down payments, tax, finance charges, license, and registration. You could even qualify for two times your money back, depending on the circumstances.

What Mercedes Benz would have to buy it back for has nothing to do with how much the vehicle is currently worth. The law has a formula that starts with you getting all your money back and then taking certain deductions and exclusions away from your payment.

Those refunds and exclusions are challenging to understand and can be fought against by knowledgeable lemon law attorneys.

Your options in a class action lawsuit

In a class action lawsuit, if the class is certified by the court, the lawyers who bring the class action will represent you unless you opt-out. You will receive a class action notice if the court certified the case to proceed as a class action and of your right to opt out of the class by a certain deadline.

If consumers prevail at the class action trial, you receive whatever relief is awarded by the judge or jury. But if they lose, you may not be able to litigate individual claims over the issues raised in the class action case.

The class action will likely settle if the lawsuit survives legal challenges. If the class action settles and the court preliminarily approves the settlement, you will receive a class notice describing your options.

Those options will be: (a) do nothing, in which case you may get nothing but be bound by the settlement, (b) submit a claim form if requested and get whatever relief is made available, and you are also bound by the settlement, or (c) opt-out and pursue your own claims, in which case you are not bound by the settlement but cannot participate in any of the relief that is being offered to class members.

For many people, a class action settlement may provide significant benefits and does not require much effort to participate. A class action settlement also comes with no risk, as the claims have been resolved.

But for others, particularly where they may have had significant damages, opting out and pursuing individual claims may provide them an opportunity to receive a better recovery in a shorter period, but with no guarantee, they will get anything in a settlement.

When it comes to vehicle defect claims, what to do can be a complicated decision, as it can depend on many factors. These factors typically include:

  • How old is your car?
  • Has the defect occurred in your car?
  • Have you taken the car in for repairs on more than one occasion?
  • Do you still own the car?
  • Is the car still under warranty?
  • In what state do you live?

If you are willing to consider the opportunity of getting a greater recovery over what might be offered in a class action settlement, we suggest you seek out a free lemon law consultation.

What is the Song Beverly Warranty Act?

handing keys over to carThe Song-Beverly Warranty Act, California Civil Code §1793.2(d)(1), is a California state law that requires manufacturers to repair defects after a reasonable number of repair attempts.

What is “reasonable” is not a hard and fast rule – safety defects should be fixed immediately, for example. The defects must be important and must “substantially impair the vehicle’s use, value, or safety.” Civil Code §1793.22(e)(2).

Under Civil Code §1793.2(d)(1), manufacturers must promptly offer a repurchase or replacement of the vehicle if they cannot fix it in a reasonable time frame. In addition, Civil Code §1794(c) and §1793.2(d) provide that customers are entitled to a civil penalty in an amount up to two times actual damages if manufacturers acted “willfully” (meaning knowingly, but not necessarily with wrongful or malicious intent) in ignoring or failing its obligation under Song-Beverly.

Finally, under Civil Code §1794(d), manufacturers such as Mercedes Benz must pay the plaintiff’s attorney’s fees and costs as part of the settlement, as the Song-Beverly Act is a pro-consumer fee-shifting statute.
