Honda Class Action Lawsuit Filed Over Drained Battery

Lawsuit alleges that Honda Accord and Honda CR-V vehicles are stalled by constant parasitic battery drain.

June 4, 2021 – Battery drain has sparked a Honda class action lawsuit alleging that Honda CR-V and 2016-2019 Honda Accord vehicles were shut down in 2017-2019 due to battery issues.

The class action lawsuit states that the parasitic battery discharge is causing multiple failures of safety functions, including the headlights and emergency warning lights that an owner needs when the vehicle stops.

The Honda class action lawsuit also alleges that multiple incidents of a discharged battery cause the alternator to work too hard and fail.

Problems with Honda Accord and CR-V batteries

The lawsuit alleges that Honda first mentioned the battery problems in February 2017 when it submitted an “Engineering Request for Investigation” to the government. Honda said it will “investigate certain 2016-2017 Accord V6s with a customer complaint about a no-start condition that requires replacement of the 12V battery.”

Honda also published more dealer messages on “Customer Complaints” in 2017[s] a no start state where the 12 V battery needs to be replaced ”in 2016-2017 Accords.

In addition, a “Tech Line Summary Article” states that the automaker conducted an “investigation” into the introduction of CR-Vs in 2017 due to weak or empty batteries, but the vehicles and batteries “check OK”.

Honda “found that a software error in the VSA” [Vehicle Stability Assist] System can keep it awake when the ignition is turned OFF. This can lead to a parasitic current consumption of 350 mA, which can lead to a weak or empty battery. “

Honda “noted that this problem only appears to occur when a certain shutdown procedure is in place, and it is rare when that is the case.” Honda allegedly had no solution but warned, “This parasitic drag can be avoided by the electric parking brake is set before the ignition is turned OFF. “

Honda also issued Technical Service Bulletin 17-03265 warning dealers that 2017 CR-Vs “may temporarily consume 350mA of electricity after the vehicle is turned off”.[,]”in which case”[t]The vehicle does not start because of a weak battery. “

“The VSA software logic may not allow the VSA modulator control unit to properly shut down and go into sleep mode after the vehicle is turned off. This can happen if the electronic parking brake (EPB) is applied within 3 to 4 seconds after the vehicle is parked or if the EPB switch is held for 3 to 4 seconds with the vehicle switched off. ”- TSB 17-03265

Honda what to “[u]Update VSA modulator controller, perform VSA sensor neutral position storage (ALL SENSOR), set tire pressures to cold pressure readings on driver’s door jamb label, and perform TPMS calibration procedure.

In 2018, Honda announced that it had launched a battery collection program for 2017-2018 CR-Vs. Then Honda issued TSB 19-039 in March 2019, warning 2019 CR-Vs that may “fail”[] to start after a long parking time. “

“After the vehicle has been idle for a long time, the PCM starts a leak test of the evaporation system after certain criteria have been met. Under certain conditions, it may not return to sleep mode, which drains the battery. ” TSB 19-039

The Honda class action lawsuit argues that battery issues have resulted in several additional lawsuits, including product updates and a notification program for CR-V owners.

“After the vehicle has been idle for a long time, the Powertrain Control Module (PCM) starts a leak test of the evaporation system after certain criteria have been met. Under certain conditions, the PCM will not return to sleep and may ultimately result in a dead battery. This is not an indication of a leak in the evaporation system. “

Persistent battery drain issues resulted in updates to service bulletins, notifications to dealers, battery collection programs, and additional TSBs.

The Honda class action lawsuit covers several complaints about discharged batteries from Accord and CR-V, including complaints filed with

In one case, the owner of a CR-V 2019 complained to her vehicle about “stable”.[ed] out “at least three times within weeks. Her SUV stopped for the first time when she was traveling at 10-15 mph on her work place. Three weeks later, while traveling 60 mph on a freeway, the CR-V died “without any warning lights or display”.

The Honda owner said the vehicle had lost power steering and the engine could not be restarted. Then, a week later, and after she had given her SUV to the Honda dealer, the CR-V stayed “completely off” and “went” while driving. [her] in danger of being hit by other vehicles.

The Honda class action lawsuit for battery problems was filed in the U.S. District Court for the Southern District of Iowa: George Jones, v American Honda Motor, Co., Inc.

The plaintiff is represented by Shindler, Anderson, Goplerud & Weese, PC, Fegan Scott LLC.
