What owners say

Filed Nov 18, 2025 · Engine, Transmission · TX

I want to say that the engine or transmission is faulty. Sometimes while at a complete stop, the car will not advance and tries to stall or lose power. It takes about 2 or 3 seconds to finally go after I push the accelerator pedal almost 3/4 throttle. No it has not been reproduced at the dealer. I took it May of 2024 for the engine recall repair. They said that the repairs should fix the problem but it has maybe even worsened. No warning lamps appear when the problems happen.

While driving car turned cel/epb/emission, car lost power while engine still running suddenly so I pulled to the side of the street. I put in park and turn engine off and on, it would not let me put in any gears . I hold down parking brakes and finally it let me engage the gears. The Acura technician found clutch positions controlled error which caused engine stall conditions, this DTC is typically caused by outdated TCM, PCM software. This situation is a safety issues, the manufacturer should fix for free, the engine stall may cause a major accident if i am on the highway

It seems that, from the day we purchased the vehicle, there have been issues with the transmission regarding how it is programmed and how it responds to drive or input through the throttle. This causes the vehicle the occasionally lurch forward under acceleration, especially at low speeds in the parking lot. And times the throttle gets really confused and the transmission fails to deliver power to the vehicle for a second. This has happened to me two or three times. I was turning left when the vehicle lost power momentarily and oncoming traffic was headed straight for me and my vehicle. If the delay had lasted just a while longer, things would have looked very bad. Based on my research online, I am not the only driver experiencing this kind of problem with the transmission.
