NHTSA Complaint #11455343 — 2019 HONDA ACCORD

Sudden engine power loss; merging to highway speed was not possible. Risk to safety was the loss was when needing to merge with traffic at highway speeds. The dealership could not reproduce the problem. The check engine light did come on, but no codes were generated. The check engine light extinguished before the vehicle could be taken to the dealership. Only possible symptom, prior to the event, and still existing, is a lack of power, compared to when it was new. The dealership cannot confirm the cause of this power loss. There are other indications that there is a controls/computer problem, in my opinion. Power assist is not always available, but then suddenly engages, causing the car to jerk. My conclusion is that the vehicle does not immediately recognize the steering input. The problem is most pronounced when traveling straight, on the highway and needing to make a mild lane correction to maintain the lane. The vehicle does not immediately recognize the mild steering input until the steering wheel has been turned significantly. Once the steering wheel has been turned significantly and the steering input is recognized, the power steering engages, causing a sudden jerk and a need to recover control. The dealership has not been able to reproduce this problem. I have been able to temporarily resolve it, by momentarily engaging the Lane Keep Assist. Normal, expected power assisted steering is recovered for a period of time.
