“Vehicle Make/Model/Year: 2019 Acura MDX Component Affected: Forward Collision Avoidance / Lane Departure / ADAS (Front Camera System) Summary of Issue: I am filing this complaint regarding a recurring and dangerous issue involving the front windshield-mounted camera on our 2019 Acura MDX. …”
NHTSA complaint #11665121, filed 2025-06“When I was at 41,528 miles, May 18, the LKAS, ACC & RDMS errors all turned on at the same time. So those systems just stopped working randomly. When I restarted the car, all errors turned off but it turned on again after 10 days, May 28 with 91,966 miles. I brought it to the Acura dealership and they couldn't replicate it. I think this is an issue because one of the highlights of this car is safety but at random times, those safety systems suddenly stops working and the dealership couldn't do anything about it.”
