Acura MDX, RDX Deceleration, Shift to Neutral, or Stall Class Action

This class action brings suit against American Honda Motor Company, Inc. and Honda Motor Company, Ltd., alleging that certain Acura MDS or RDS vehicles have a defect that can cause hesitation, sudden deceleration, engine stalls, or other problems while the cars are being driven.

The class for this action is all individuals in the US who bought or leased a model year 2016-2020 MDX or model year 2019-2020 RDX vehicle. The complaint also defines a California Subclass, a CLRA [California] Subclass, and an Implied Warranty Subclass.

Early on, the complaint quotes a posting at the National Highway Traffic Safety Administration (NHTSA) that describes the problem:

“While driving, the MDX shifts into neutral and cannot be shifted out of neutral. This has occurred on the highway multiple times…. Having your vehicle shift into neutral in a high speed environment is extremely dangerous…. [This] needs to be a recall before their MDX shifts into neutral driving on the highway and they become immobilized and people are killed…”

What’s the problem? The complaint points to the Engine Control Module (ECM, also known as the Powertrain Control Module) and the Transmission Control Module (TCM). The vehicles supposedly have a Drive-By-Wire Throttle System.

The complaint quotes Honda’s description of this system as “giv[ing] racing-inspired pedal movement and smooth, powerful response with just-right throttle sensitivity for most situations by replacing traditional cables with electronic components. Data is instantly factored in from engine RPM, coolant temperature, road speed, transmission status and more.”

However, in order for all this to work, so that when the gas pedal is depressed, the vehicle accelerates without hesitation, stalling, or other problems, the complaint says, “the powertrain components, including the Throttle System, ECM/PCM, and TCM[] must all communicate with each other seamlessly. Upon information and belief, they do not.”

The complaint further claims that “Honda has failed to permanently repair or replace the defective parts free of charge under the warranties.”

According to the complaint, Honda knows about the problem. In July 2015, Honda issued Technical Service Bulletin (TSB) 15-034 about the problem with respect to the 2016 Acura MDX. It described how the vehicle could shift into neutral while it was being driven, saying, “The driver will not be able to select any other gear until the vehicle is turned off and restarted.” Another TSB described the problem was issued in 2019.

The complaint alleges that the fixes described in the TSBs do not solve the problem.

In January 2019, Honda recalled 2016-2018 Acura MDX vehicles. However, the complaint alleges that the repairs done at the time also failed to solve the problem.

The complaint alleges fraud, breaches of warranties, and violations of state consumer laws, among other things.
