   The forward facing camera in the windshield went out causing all these systems to stop working and dash light up like a christmas tree. I cant even use normal cruise control. Dealer wants $1700 to replace it. From what I am reading online this is a very common problem and Acura even superseeded the part. Was that due to failures? I have yet to get this repaired as it is so expensive but i would really like these safety features. 36160-TZ6-A36

   The multipurpose camera on my 2018 Acura MDX intermittently fails and stores DTC U3000-49. When the failure occurs, multiple AcuraWatch/Honda Sensing safety systems become unavailable, including Collision Mitigation Braking System (CMBS), Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), and Road Departure Mitigation (RDM). The vehicle displays numerous safety-related warning messages on the dashboard. The issue is intermittent and appears to occur randomly.…

   Front camera stopped working at 65 000 miles. Seems to be a faulty part as many Hondas and Acuras have the same problem and the dealer wants over $2000 to replace a $700 part that sounds like less than 45 minutes to replace.

   While driving the car, several warning lights turned on all at once, saying that the following components were disabled: Lane Keep Assist, Adaptive Cruise Control, Automatic High Beams, and Collision Mitigation Braking System. Not being able to use these features is more dangerous, not to mention that the warning lights associated with their disabling are distracting (making it likely that, if a more serious warning was flashing, it would not be noticed by the driver) and…
