There are 2 owner-reported driver assist & adas complaints for the 2023 Acura MDXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I have taken my vehicle to the Acura service department three times for this issue. Each time, they were unable to find a fault code or permanent fix. They have repositioned the front camera and removed an Acura sticker from the windshield, but the problem continues to occur at random. The service department said diagnostic tests show no error, yet the system still triggers false collision warnings. I’m concerned about the safety of driving a vehicle whose collision avoidance system malfunctions without warning. This issue has occurred on city streets and highways, in clear weather, at various speeds. The alerts come on suddenly with no obstruction ahead. Acura has not provided a permanent fix, and I feel unsafe driving the vehicle. I am requesting that NHTSA investigate whether this is a common defect in 2023 Acura MDX models.
While driving at approximately 25 mph with no vehicle in front of me and no objects in the road ahead of me, the automatic braking system suddenly and unexpectedly engaged and brought my vehicle to a near stop. This was sudden and unexpected and the vehicle behind me nearly collided with my vehicle. It also caused my head/neck to jolt forward and while I did not sustain an injury it was a significant “jolt”. The vehicle is available for inspection upon request. My safety and the safety of others was put at risk by my vehicle suddenly and unexpectedly braking automatically for no reason. This issue could easily cause collisions and injure me, my passengers, and occupants of vehicles driving behind my vehicle who may not be able to slow down or stop in my time when my vehicle automatically brakes suddenly and without warning, for no apparent reason. The problem has not yet been reproduced or confirmed by a dealer or independent service center. The vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others. When the brakes suddenly engaged, the “Brake” warning flashed on the driver panel/screen in a yellow/orange color. There were no other warning lamps, messages, or other symptoms of the problem prior to the automatic braking system suddenly engaging for no reason.
