NHTSA Complaint #11716599 — 2017 ACURA MDX

There were several instances where my vehicle either accelerated or decelerated while I was driving. I first noticed the issue about a week after I purchased the car in May 2022. I took it back to Acura of Brookfield, and they said they couldn’t replicate the issue. I also took my car to Acura of Brookfield in September 2023 for the same jerking issue. They charged me for an update, but the issue did not change. I continued noticing the problem over the years, but it happened more frequently in 2025. In May 2025, I was driving down a hill in Brookfield, Wisconsin, when my car jerked aggressively and then accelerated on its own. Throughout the rest of the year, it would either accelerate or decelerate while I was on the highway. On January 20, while I was on my way to the gym, my car jerked and decelerated while I was on the highway. I was able to pick up speed again and continue driving to the gym. When I came back out, my car started, but it would not shift out of park. I had the car towed to Acura of Brookfield, and they said something about the hydraulics inside the transmission being bad, and that they had to replace the entire transmission.
