1) I was struck by a vehicle that ran the stop sign at 50mph. After the impact my vehicle continued rolling forward and wouldn’t stop. I ended up a block away from the accident and my emergency brake, brake pedal and center console brake would not engage. My vehicle was stopped after a car pulled up infront of me for me to rear end it to stop. Vehicle is a total loss and sitting in a tow yard. 2) I was in the vehicle with my 3 children under 7 years of age.

Within a month of buying our 2023 mdx the rear parking sensor stopped working. When we took it to the dealer (10/23) they were unable to get the part. Car sat at dealer waiting on part but we finally decided to just get car back. Within a week of getting it back (12/23) I turned the car on one day and on the screen every system that could fail was flashing on the screen- brake system, power steering, parking assist, etc. The car was not draining correctly as all these alerts flashing. We finally had to get it towed to dealer (could not even get car in neutral to get onto tow truck). Still waiting on the rear sensor part to see if this fixes all the issues.
