“5 waning lights on : Adaptive Cruise Control , Lane Departure Warning , Lane Keeping Assistance , front light, and the emergency braking . Service crew at Acura Dealer told me that the front multipurpose camera has internal error. It is very dangerous since all these functions must be fixed before I can drive it on road.”
NHTSA complaint #11666753, filed 2025-06“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”
