Investigation of 2013-14 Acura MDX and RDX vehicles equipped with Variable Cylinder Management system over excessive noise and vibration


Lawyers have commenced an investigation of 2013-14 Acura MDX and RDX vehicles equipped with  Variable Cylinder Management system that cause excessive noise and vibration when engaged.

In 2013 Acura introduced engines with a Variable Cylinder Management system which was designed to pause a portion of the engine’s cylinders at various times during the vehicles operation which would lead to  improved fuel consumption, exhaust gas reduction, and higher engine performance at high speeds.

Many Acura drivers have complained of excessive noise and vibrations from the undercarriage and engine compartment when the VCM engages.  Honda faced similar VCM problems in its Accord, Odyssey and Pilot vehicles resulting in a class action lawsuit and subsequent settlement that extended the power train warranty on affected vehicles.

If this has happened to you, please share your story with us, and/or contact us privately about your legal rights.

Honda named in class action lawsuit over excessive vibration in 2015 CR-V vehicles

Honda recently introduced its 2015 model year CR-V, announcing that the new model year would come with substantial upgrades. Most prominently, Honda advertised a new engine and transmission that was projected to make the 2015 CR-V “best-in-class” in fuel efficiency.

According to the complaint Honda’s quest to improve the CR-V’s fuel efficiency came with a significant tradeoff. Typically, auto manufacturers must balance fuel efficiency against customer comfort since several methods for improving fuel efficiency also cause noise, vibration, and harshness problems. In its over-eagerness to optimize the CR-V’s fuel economy, Honda produced a vehicle that experiences a substantial vibration at idle and low speeds—a vibration that drivers describe as “severe,” “extremely distracting,” and “nauseating.”

Honda knew about the vibration before it began selling the 2015 CR-V and had several viable options for mitigating the problem. But modifying the CR-V would either have reduced its fuel efficiency or required Honda to install costly components to dampen the vibration. Alternatively, Honda could have disclosed to consumers that the CR-V is prone to severe vibrating, and allowed consumers to make an informed purchasing decision using that knowledge.

As alleged, Honda chose instead to sell the CR-V as is. Not trusting that consumers would opt to buy a CR-V if they knew of the vibration in advance, Honda hid the problem from the car-buying public. When customers return (often just days later) to complain, Honda refuses to fix the problem or refund their money.
