Honda Engine Problems: Filing of a Class Action Lawsuit
Honda has always been renowned for its reliable engines, but a new class action lawsuit in the US points to serious problems with some 1.5- and 2.0-liter four-cylinder engines. According to the lawsuit, these engines cannot withstand high compression and temperature, leading to overheating, head gasket failure, and other expensive-to-repair malfunctions.
One of the main claims is that the gaskets in these engines crack, allowing coolant to leak into the cylinders. This, in turn, can cause engine seizure or even fire. White smoke from the exhaust pipe can be a sign of coolant entering the combustion chambers.
Which Models Are Involved?
Five models are included in the lawsuit: Honda Accord (2018–2022), Honda Civic (2016–2022), Honda CR-V (2017–2022), Acura RDX (2021–2022), and Acura TLX (2019–2022). Six plaintiffs, most of whom owned 2018–2019 Accords, accuse Honda of refusing warranty repairs, even if the vehicles are still under warranty.
This is not the first time the 1.5-liter i-VTEC engines have been the subject of litigation. In 2024, a lawsuit was already filed in California over sealing and cooling issues, which led to coolant leaks and loss of power.
The plaintiffs are seeking compensation for damages, court costs, and a jury trial. Honda has not yet provided an official comment on the situation, but the question of its engines’ reliability could affect consumer trust in the brand. This is the second major complaint about the quality of the company’s powertrains in recent years.
