Honda Sued Over Minivans That Have Trouble Stoping and Starting

A new 132-page class action lawsuit, filed in the U.S. District Court for the Central District of California, alleges that 2018 through 2025 model-year Honda Odyssey minivans are equipped with a defective starting system that can leave families stranded.

The core of the complaint focuses on a dual mechanical fault within the starting and charging ecosystem. According to the plaintiffs, the Odyssey's battery system fails to maintain an adequate charge during normal driving conditions, keeping the electrical system in a perpetual low-voltage state. This lack of electrical power results in insufficient torque from the starter motor to turn over the 3.5-liter V6 engine.

The filing alleges this failure occurs in two common scenarios: when the vehicle refuses to crank after being parked for short intervals, and when the factory stop-start system shuts down the engine when stopped in traffic.

The lawsuit claims that Honda has been aware of the starting system's hardware limitations for years through integrated dealership repair metrics, technical bulletins, and consumer field data. While Honda previously issued internal technical service bulletins recommending fuel injection software patches and selective starter motor replacements for related starting faults in other V6-equipped models, the plaintiffs claim Odyssey owners were excluded from the underlying hardware upgrades and subsequent warranty extensions.

The legal action seeks financial damages and a comprehensive remedy for affected owners.
