Honda Idle Stop Lawsuit Certified as Class Action

Lawsuit Moves Forward Over Alleged Engine Restart Failures

A class action lawsuit targeting Honda has officially been certified, allowing it to proceed on behalf of affected owners in multiple U.S. states. The lawsuit accuses Honda of selling vehicles equipped with a defective Idle Stop feature, which allegedly fails to restart the engine once the brake pedal is released, posing serious safety risks.

Filed under the consolidated case name “In re Honda Idle Stop Litigation,” the lawsuit stems from complaints that began surfacing shortly after a government investigation into the Idle Stop systems was announced. The class action combines three individual suits: Bolooki v. Honda, Cooper v. Honda, and Nock v. Honda.

What Vehicles Are Affected?

The class action covers the following Honda and Acura models equipped with NP0 engines, nine-speed automatic transmissions, and the Idle Stop feature:

  • 2015–2020 Acura TLX
  • 2016–2020 Acura MDX
  • 2016–2021 Honda Pilot
  • 2019–2021 Honda Passport
  • 2020–2021 Honda Ridgeline

However, vehicles that received a free starter motor assembly replacement (A53) under warranty are not included in this lawsuit.

Eligible vehicles must have been purchased or leased in California, Indiana, Louisiana, Maryland, New Hampshire, Pennsylvania, Texas, or Virginia. The lawsuit also covers vehicles from Alabama, Connecticut, and Washington, but only if they were bought or leased through authorized Honda or Acura dealerships in those states.

Plaintiffs Say Fixes Were Inadequate

Honda maintains it has done nothing wrong and claims that the Idle Stop issue was resolved through a software update and warranty extensions. But plaintiffs argue that these fixes were ineffective and that Honda continued selling vehicles knowing the system could fail to restart the engine, potentially leading to dangerous traffic situations and even bodily injury.

A jury trial is scheduled to begin on May 20, 2025. In the meantime, no settlement has been reached. The lawsuit aims to obtain compensation, repairs, and injunctive relief for impacted vehicle owners across several states.

The case is filed in the U.S. District Court for the Central District of California:

In re Honda Idle Stop Litigation (Hamid Bolooki v. Honda Motor Company Limited, et al), Case No. 2:22-cv-04252-MCS-SK.
