A class action lawsuit alleges that 2017–2019 Honda CR-V and 2016–2019 Honda Accord vehicles experience parasitic battery drain and eventually shut down.
The parasitic draw allegedly causes vehicle stalling and failure of headlights, emergency hazard lights, alternators and important safety functions.
According to the lawsuit, Honda initially filed an investigation with the government in February 2017 for battery issues in some Honda Accord cars. Though Honda conducted an investigation into some 2017 Honda CR-Vs for weak batteries, the automaker allegedly said the vehicles and batteries “check out ok.”
However, Honda found that a software bug in the Vehicle Stability Assist system may result in parasitic draw, causing weak or dead batteries.
Honda issued a technical service bulletin to dealers in 2017 and in March 2019. In 2018, it issued a battery collection program for 2017–2018 Honda CR-V vehicles.
The class action lawsuit cites several additional actions on Honda’s part as evidence of continuing battery problems in the affected models. Some affected vehicle owners alleged that their vehicles stalled multiple times in weeks, sometimes on highways or other particularly unsafe driving situations.
