Owner complaint summary

The subject 2019 Acura MDX model includes the tech package which adds several safety features that function through a windshield mounted camara/radar. The system has malfunctioned and none of the safety features are working. The dash displays the following messages: Collision Mitigation System Problem Adaptive Cruise Control Problem Lane Keeping Asist Problem Road Departure Mitigation System Problem automatic headlight system problem At the bottom of the dash, I see Brake System, Crash Warning and Lane Departure lights on as well. Acura is charging $2,319 to replace this unit in addition to a $270 diagnostic fee. This issue is widely reported as a significant issue in several model years for the MDX and should be part of a safety recall. The Acura technician acknowledged this issue is common. I should add this is the second major electronic issue with this MDX within the last several months. The prior issue was multiple system failure warnings that Acura determined were caused by a faulty wiring harness at a $1,604 cost, plus a $255 diagnostic fee. Please note I am the original owner of the vehicle and it has never been in a collision. Additionally, the system has recently mistakenly activated the brakes at very low speed and warned against collisions with other vehicles traveling in the opposite direction while on a curve.
