Honda class action lawsuit overview:

  • Who: A group of six consumers has filed a class action lawsuit against American Honda Motor Co. Inc. and Honda Motor Co. Ltd.
  • Why: The plaintiffs allege the automaker sold vehicles with defective turbocharged engines that are prone to overheating, head gasket failure and other problems.
  • Where: The Honda class action was filed in California federal court.

A new class action lawsuit accuses American Honda Motor Co. Inc. and Honda Motor Co. Ltd. of selling vehicles with defective turbocharged engines that are prone to overheating, head gasket failure and other problems.

Plaintiff Radley Alcantara and five others filed the Honda turbocharged engine lawsuit against Honda on July 1 in California federal court.

The plaintiffs allege Honda’s 1.5-liter and 2.0-liter turbocharged engines, found in vehicles like the Honda Accord, Civic, CR-V, Acura RDX and TLX from model years 2016 to 2022, have a design defect that causes engine coolant to leak into the cylinders.

This leads to overheating, head gasket failure and other serious issues, they say.

Honda refuses to fix defect, lawsuit claims

The plaintiffs argue that this defect poses a significant safety risk, as it can cause vehicles to lose power suddenly, potentially leading to accidents.

They claim Honda was aware of the defect but failed to disclose it to consumers, leaving them with unreliable and expensive vehicles.

The lawsuit alleges the automaker has refused to fix the problem under warranty, forcing consumers to pay out of pocket for repairs.

The plaintiffs are suing for breach of warranty, unjust enrichment and violations of consumer protection laws. They are seeking certification of the Honda turbocharged engines class action lawsuit, damages, fees and costs, and a jury trial.

Last year, Honda was hit with a similar class action alleging defects in its 1.5-liter i-VTEC turbocharged gasoline direct injection engine, which reportedly suffers from “inadequate sealing and cooling.” According to that lawsuit, coolant leaks into engine components, causing overheating, loss of power, and contamination of engine oil.

What do you think of the claims made in this Honda class action? Let us know in the comments.

The plaintiffs are represented by Timothy G. Blood, Thomas J. O’Reardon II, Paula R. Brown and Adam M. Bucci of Blood Hurst & O’Reardon LLP; and W. Daniel “Dee” Miles III, H. Clay Barnett III, J. Mitch Williams, Dylan T. Martin and Trenton H. Mann of Beasley, Allen, Crow, Methvin, Portis & Miles PC.

The Honda turbocharged engines class action lawsuit is Alcantara, et al. v. American Honda Motor Co. Inc., et al., Case No. 2:25-cv-06009, in the U.S. District Court for the Central District of California.

    2021 Honda Civic 3 months after getting the car I noticed the acceleration issues. Took it to Honda twice to be told there was nothing wrong. At 40k miles after my warranty expired (according to my owners manual) my camshaft position sensors (yes both) went out. Fixed those then my ignition coil on my 4th cylinder went out. Got that fixed to find my turbo was out. I just got it replaced to find out my 4th cylinder and head were shot. My mechanic told me to contact Honda. I did and come to find out, I have a 60k miles or 5 year on my power train and the turbo along with the engine are included in that.
    I just dropped $4000 at my mechanics because the f$&king book said I didn’t have a warranty. Honda is now fixing the rest of the engine, under warranty, that my mechanic didn’t do. So they are saving me $2000 and it doesn’t sound like they are going to reimburse me for the $4000 I’ve already paid.

    I have 2019 crv w/blown head gasket
    I don’t have the warranty…honda motor company said they possibly would give me a good will service help by paying a portion of the repair at the honda dealer… But I had to make sure that I got my car diagnosed at a dealership. Paid the money to get it diagnosed at the dealership. But then I called back honda motor company and they said that they wouldn’t help me with any good will financing after all.. because of reasons Unknown to me. The repair quote was over 9k! I towed the car home… And it’s such a beautiful car too.. sits there with a broken head gasket in my garage… I am contemplating now having a different guy Look at it…he likely going to charge about five or six grand or more … :(
    It was a very big investment just to buy the car. And now I have to pay all this money to get it back on the road again… Is there any way that I can please be included in the the class action lawsuit?
