NHTSA Complaint #11659101 — 2018 HONDA ODYSSEY

9 speed transmission issue: Ever since I purchased this vehicle around 50,000 miles in February of 2021 (mileage currently at 118,048), I noticed a very obvious delay in acceleration from a complete stop. Changing to eco drive mode and sport mode changes slightly, but still has delay. Transmission fluid has been changed 3 times since owning this vehicle and everytime it has, there was no noticeable changes in symptoms. Delayed acceleration occurs more consistently at normal operating temperatures. Brought vehicle to honda dealership after purchasing. They performed a TCM software update. Problem still occurs to this day. Multiple occasions occured where me and my girlfriend are driving and attempting to make a safe left turn only to proceed, but in process of attempt, the vehicle delays while facing oncoming traffic.
