A New Jersey woman recently filed a class action lawsuit alleging that certain Hyundai Elantra models have a piston defect which can cause dangerous engine failures.

Plaintiff Elizabeth Brown filed the class action lawsuit against Hyundai Motor America and Hyundai Motor Company LTD, alleging that the car maker’s Elantra models posses a dangerous piston defect.

The Hyundai Elantra class action claims that Elantra models from 2011 through 2016, with “Nu” 1.8 liter engines, are affected by a piston defect.

Brown says the piston defect stems from 2011 changes to the piston manufacturing process.

The Hyundai class action lawsuit alleges that Brown purchased a 2013 Hyundai Elantra, containing a “Nu” 1.8 liter engine, from an authorized dealer near her home.

In late 2017, Brown reportedly began to notice a knocking, ticking noise from her vehicle. A week later, while her son was driving the car, a loud pop was heard from the engine before it failed.

The plaintiff says she attempted to file a warranty claim but was denied when the dealer allegedly found oil sludge, citing inadequate maintenance.

The Hyundai Elantra piston defect can allegedly cause engine failures. The symptoms of the related engine failure reportedly include a knocking noise upon start up, loss of engine power, loss of power steering, loss of break assistance, and sudden stalling.

The Hyundai Elantra class action lawsuit claims that once the engine fails, there is no way to fix it apart from completely replacing the engine, a $10,000 repair.

Brown argues that Hyundai Elantra engine failure can place consumers at serious risk for accident, injury, and death. If a Hyundai Elantra engine were to fail while a consumer was driving, they would reportedly be at serious risk for collision.

The Hyundai Elantra class action claims that the automaker knew about the defect but did not initiate a recall or repair action in the United States.

Brown says Canadian dealers were instructed to replace engines affected by engine knocking, a symptom of the problem, but no such order was initiated in the United States.

Instead of offering a fix for the dangerous problem, Hyundai Elantra dealers blame consumers for “inadequate maintenance” and deny warranty claims for a replacement engine, according to the Hyundai Elantra class action lawsuit.

“Defendants have not recalled and/or offered an adequate engine repair to the Class Vehicles, offered their customers suitable repairs or replacements free of charge, or offered to reimburse their customers who have incurred out-of-pocket expenses to repair the defect,” the Hyundai Elantra class action states.

Brown seeks to represent a Class of current and former owners and lessees of Hyundai Elantra vehicles affected by the alleged piston defect. She also seeks to represent a New Jersey subclass of the same consumers.

The Hyundai Elantra class action seeks compensatory damages, punitive damages, injunctive relief, court costs, and attorneys’ fees.

Brown is represented by Matthew D. Schelkopf and Joseph B. Kenney of Sauder Schelkopf LLC; Nicholas Migliaccio, Jason Rathod, and Esfand Y. Nafisi of Migliaccio & Rathod LLP; Daniel C. Levin of Levin Sedran & Berman.

The Hyundai Elantra Piston Defect Class Action Lawsuit is Brown v. Hyundai Motor America, et al., Case No. 2:18-cv-11249-JLL-JAD, in the U.S. District Court for the District of New Jersey.

UPDATE: On Jan. 22, 2019, Hyundai asked a federal judge to dismiss a class action lawsuit which alleges that the company concealed Elantra engine defects.

    My daughters car just seized up the motor same knocking noise and now have to replace it on our dime how do we join a suit

  2. Jesse says:

    My 2011 Elantra has occasionally had the knocking noise for about 2 years. Hyundai replaced a piston under warranty, but the issue is still around-and sometimes it hesitates before starting.

  3. Dan says:

    I would like to be added to lawsuit, 2011 Hyundai Elantra

  5. Tammy says:

    I bought the 2013 Hyundai Elantra with 58,000 miles. The car has been maintained, as confirmed by the local Hyundai dealership. At 66,000 miles it started making the ‘knocking’ sound (it’s awful) and a loss of power. I’ve had it parked for months. I work out of town/state and live in the country so it’s hard for me to just ‘take it in’. Finally was able to get it to a dealership and Hyundai is saying no, it’s not covered. But of course they said they’d meet me halfway and my cost would be $3,500 to $4,000. I still owe 7 grand on the car. It’s still parked and I’m still making the payments on it. Shame on you Hyundai.

    I have a 2013 Hyundai Elantra and my son has a 2012 Hyundia Elantra how do we sign up my car is making the same noise should I keep driving it or not I use it to get my kids around so I need something safe and reliable

  7. Bill says:

    I had to replace my 2012 elantra engine. Hyundai would not warrany it. Said it’s not on the list. I said maybe it should since i have the same problem.

  8. Jeff says:

    I had my engine replaced (partially paid under extended warranty) around 80K miles for my 2015 Elantra. Would love to be part of this suit if possible. Same knocking noise and mechanic told me I needed a new engine. Thought it was just a cracked flywheel.

  9. Jennifer says:

    I am having the engine knocking currently. The Hyundai dealership has recommended engine replacement but I am unable to afford it at the moment. Buying a new car isn’t an option at this moment either.

    1. Sabine says:

      I have a 2012 Elentra. My engine has been knocking for years. Hyundia has run all kinds of test on it over the years and has never been able to find a thing. I guess ill just have to wait for it to stall or blow up.

  10. Cosette says:

    I had the exact same issues with my 2012 Elantra. Of course it was shortly after warranty was up and over a thousand dollars just to investigate what the problem was with the engine I decided I could not be in anymore financial strain for a car I was still making payments on. I was very disappointed!
