Auto Idle Mode - After we've stopped and released the brake to go forward, the car will then shift to neutral by itself instead of restarting to drive. This has happened frequently and is now starting to happen more often. This is a safety issue, especially if you're the last car in line and other cars are traveling 55-60 miles behind you on a major road and see a green light ahead. Each time this happens, we have to turn off the car and try to restart the car, and sometimes this has been iffy and we've had to repeat the process a couple of times. There were no warning lights of problems with any of car components. There have been similar reports of this occurring: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on the highway, at highway speeds, all dash lights came on and the vehicle immediately lost power coming to an abrupt stop. We were able to limp the car to the side of the road. It was ultimately determined that the car’s fuel pump had gone out. The fuel pump was replaced by Acura, and covered under the initial manufactures warranty. However, it’s rather suspicious that our car is not included in the recall given that the fuel pump failure is identical to the open recall for our same make and model.
While driving, in the middle of the high way, the car shuts off and stops and when restarted it wouldn’t go. Stopped, twice this month and three time total this year, on the Highway thank god no accident.

I have experienced sudden acceleration problem numerous times( 5 to six times. The latest one was march 1,2021. The vehicle would accelerate (RPM rapidly ) suddenly when driving at low speeds(around 10 to 15mph to a quick almost 30mph without pressing the gas pedal) that always require me to break immediately to avoid any accidents. I had the vehicle checked thoroughly by a company sent expert last year(sometime nov ,2020) and they can't replicate the problem. Acura relations can't help me anymore . It made me google unintended acceleration mdx. The problem is for real. Had I known this problem, I wouldn't have leased this vehicle last oct.31, 2019. Please help. Many thanks
