Honda’s Earth Dreams Engine Oil Problems Prompt Lawsuit

Honda Earth Dreams engines allegedly experience defects that cause poor oil dilution and engine stalling in 2019–2021 Honda CR-V, 2019–2021 Honda Civic and 2018–2021 Honda Accord vehicles.

The Earth Dreams 1.5L direct injection engines have defects that cause a build-up of non-combusted fuel in the oiling system. As a result, the oil cannot properly protect the bearings. The bearings for the connecting rods contact the rods, and the crankshaft makes contact with the main bearings. Worn out bearings allegedly cause the engines to stall and, ultimately, fail.

The Honda class action lawsuit also alleges that Honda fails to provide adequate repairs to the vehicles and tells consumers that the problems can be fixed by driving longer distances.

The lawsuit alleges that Honda knew about the oil dilution problems in the affected Earth Dreams engines, citing customer service programs, warranty extensions, and past lawsuit settlements. However, these past arrangements have allegedly not fully satisfied the needs of affected drivers.

Honda announced a customer service program in 2018 for 2017–2018 Honda CR-V drivers in United States and other vehicle owners in Canada.

A black vehicle is parked on a dirt road, surrounded by grass.

According to the program, the oil dilution issue happened mostly in cold weather.

Honda received several complaints of gasoline mixing with engine oil in the 1.5L Earth Dreams engines, which prompted an extension of the factory warranty in more than a million 2017-2018 Honda CR-V and 2016-2018 Honda Civic vehicles the following year.

A class action lawsuit approved in 2020 included an extended warranty for affected 2016-2018 Honda Civics and 2017-2018 Honda CR-Vs equipped with 1.5-liter Earth Dreams engines.

However, none of these past programs required full reimbursements or engine replacements.
