NHTSA Complaint #11604992 — 2021 HONDA PASSPORT

I have experienced multiple instances where the vehicle's transmission abruptly downshifts into lower gears, significantly reducing speed and creating a hazardous situation. This unexpected behavior has occurred on the Interstate, both while merging onto the highway and during regular driving conditions. On two separate occasions, my daughter was driving the vehicle when the transmission malfunctioned while driving on the Interstate. She was terrified as she believed she was losing traction and was unable to accelerate properly, putting her life and the lives of others at risk. I have personally experienced this issue as well when attempting to merge onto the Interstate under clear and dry road conditions. The vehicle would not exceed 35 mph, creating a dangerous situation. To rectify the issue, I had to pull over to the side of the road, place the car in park, and then put it back in drive to regain normal acceleration. I have used a code reader to check for any diagnostic trouble codes, but none were present. However, a blinking traction control light illuminated during these incidents, indicating a potential issue. I am deeply concerned about the safety implications of this problem.
