Summary of Complaint
Our 2018 Honda Odyssey repeatedly and without warning completely loses acceleration power, creating extremely dangerous driving conditions. This occurs in two distinct situations:(1)while driving at highway speeds when attempting to change lanes or accelerate, and(2)when stopped at a stop sign or intersection and pressing the gas to merge into or turn into traffic. In both situations, pressing the accelerator results in little to no response — the vehicle will roll but fails to accelerate as needed. These failures have placed our family in multiple life-threatening situations. On Interstate 285 in Atlanta, Georgia — one of the busiest and highest-speed highways in the country — our vehicle has failed to accelerate during lane changes on multiple occasions, nearly causing serious accidents. Most recently, within the past week, my husband was driving on I-285 when he pressed the accelerator and the vehicle had absolutely zero acceleration response. He narrowly avoided a collision. We have also experienced complete loss of acceleration when turning from a stop sign into traffic and when merging — situations where immediate acceleration is critical to safety. The vehicle lags for several seconds before any power is delivered to the wheels, leaving us dangerously exposed in oncoming traffic. All manufacturer recalls have been completed, including the fuel pump recall. The problem persists and has not been resolved by any dealer service or recall repair performed to date. We are aware that this is a known, widespread defect affecting 2018 Honda Odysseys equipped with the ZF 9-speed automatic transmission. Hundreds of other owners have reported identical symptoms to NHTSA and to Honda directly. Honda has acknowledged the transmission's behavior to some owners but has stated it is "how the car is supposed to drive" — a response that is wholly unacceptable given the documented near-accidents this defect is causing.We are requesting that NHTSA open or expand its investigation
