2019 Acura RDX Transmission and drivetrain Problems

“I reported an issue with my 2019 Acura RDX, where if: engine auto stop is enabled, and brake hold is enabled. On two occasions, the vehicle lurched forward while the brake hold is enabled this propelled me to the side of the intersection today, with a 2020 loaner, it happened again”

“On 4/17/2021 my wife and I were traveling form florida to california, while traveling on I -49n in louisiana I went to accelerate around a slower car and when I pushed the gas our car lost power and the check engine light started flashing causing us to suddenly slow down and almost being stuck by other automobiles in traffic. I was able to make it over to the shoulder of the interstate and shut off our SUV for about ten minutes and the issue was gone.”

“While traveling cross country on the second day of travel I attempted to accelerate to pass a car at appx 75 MPH and my car suddenly and rapidly started to decelerate. I noticed that the check engine light was on and I could only reach speeds of appx 40mph. Once I made it to the shoulder I turned the vehicle off and waited apprx 1 minute before restarting. After restarting, I preceded to complete the trip without further incident. I have not experienced this condition since the reported incident. …”

I was lucky to have been missed by the traffic behind us and was able to get to the right shoulder. The car would not accelerate past 10-20mph. We limped to the next exit and found a parking lot. I turned the car off and back on and it seemed to be working correctly again. My entire family could have easily been killed! …”

“I know by now the public may realize all the issues surrounding the 2019 RDX model. I purchased one three months ago. While there are a host of important issues/problems I have seen with the vehicle, all 'appear' to be software related, I would like to express my concern with one specific issue. The throttle is delayed when accelerating from a standstill up to 10 MPH, but can also happen at higher speeds. This appears to be dependent on the RPM. This occurs in comfort and sport modes.
