36 Automatic Emergency Braking problem of the 2017 Acura MDX

Failure Date: 12/15/2021

This morning I read that you were investigating the automatic braking for certain Honda models. I have had this same thing happen with my 2017 Acura Mdx several times over the past few years. I would be driving (not following another car), and my car would suddenly brake and flash "brake" on the screen, without my doing anything. Both times, I attributed the issue to driving into a bright sun, but I am not sure. It did not cause an accident and it was not a big deal, but the last time (about 3 months ago) I remember braking and being nervous about someone else read ending me. . . When I tried to accelerate I was unable to do so.

38 Automatic Emergency Braking problem of the 2017 Acura MDX

Failure Date: 07/02/2021

2017 Acura Mdx purchased may 2020. Incidences has happened 5 times. Twice this month in July 2021 the brakes engaged! anxiety and fear of being hit by cars behind. 1st incident:location back road when the brakes engaged the vehicle in front had taken a right turn. The vehicle was cleared from mine so it came as a scare as it stopped in the middle of the road with others behind me honking…. . The brakes released and I proceeded driving. 2nd:location back road again in front a vehicle turned right and the brakes engaged. I hit the gas gently I dont know if that helped to disengage the brakes or not. 3rd: location highway brakes engaged and immediately released. I was in passing lane and a truck in middle lane …. . This made no sense. 4th: location at intersection truck turned left across and in front of me, brakes engaged and stopped my car, only to find out a low trailer was being towed. Brakes did help prevent an accident. Kudos earned here!!!! 5th: location back road speed less than 40mph vehicle in front of me turning right again my brakes engaged! again I used the gas hoping the brakes would disengage. I dont know if it helped or not. Now I only use the cruise control on highways.

39 Automatic Emergency Braking problem of the 2017 Acura MDX

Failure Date: 07/01/2021

At different times, either with my wife or I driving the vehicle, we will receive error messages on the dash indicating that various systems are inoperative. These involve the lane keeping assist system and the braking system. I also believe that the cruise control does not function when these messages appear.

40 Automatic Emergency Braking problem of the 2017 Acura MDX

Failure Date: 04/01/2021

While driving on normal road with no other cars around, the emergency braking system/forward collision activated and immediately stopped my car with no danger present. This resulted in the car behind me swerve to avoid hitting me in the rear. No warning lights were on the dash or no audible warning either. This seems to be a malfunction in the system.

41 Automatic Emergency Braking problem of the 2017 Acura MDX

Failure Date: 03/17/2021

Incident #2 driving down city street approaching an intersection. No car in front and no car behind. In the middle of the intersection the car auto brakes to a complete stop before releasing back to normal. If a car were behind me I would have most surely been rear ended.

42 Automatic Emergency Braking problem of the 2017 Acura MDX

Failure Date: 08/12/2020

Driving on the highway at about 80 mph and as I was rounding a band the car automatically started breaking with no cars in front of me. The car almost came to a complete stop before it out of alleviated the breaking and allowed me to continue to accelerate.
