The factory-installed led daytime running light (drl) system on my 2019 Acura Rdx has failed. The passenger-side drl is completely inoperative, and an authorized Acura dealership documented that the driver's-side drl is beginning to fail as well. The affected components are available for inspection upon request dealership has declined to provide further documents and american Honda moto daytime running lights are a safety-related exterior lighting system designed to improve vehicle visibility to other motorists. The failure of one drl and the developing failure of the second drl may reduce vehicle visibility and create a potential safety concern. On July 3, 2026, cerritos Acura inspected the vehicle and confirmed the condition. The dealership's written diagnosis states: "recommend passenger headlight assembly due to daytime running light out. Recommend driver's headlight assembly due to daytime running light going out as well. " the dealership recommended replacement of both headlight assemblies. The dealership found no evidence of collision damage, misuse, unauthorized modifications, or water intrusion. The drl is an internal led component that is not serviceable separately and requires replacement of the entire headlight assembly. The vehicle has been inspected by cerritos Acura, an authorized Acura dealership. To my knowledge, the vehicle has not been inspected by police, insurance representatives, or any government agency there is no record of any only with the dealership. There were no warning lights, warning messages, dashboard indicators, or other symptoms before the failure occurred. The drl failure happened without warning and was later confirmed by dealership inspection. I am concerned that the failure of both factory-installed led drl assemblies may indicate a defect in the lighting system rather than normal wear and tear. The condition was confirmed by an authorized Acura dealership and was not attributed to accident damage or other external causes.
Auto high beams appear to turn on when there are light colored vehicles in front of the car. This issue does not appear to be isolated to our vehicle: https://acurazine. Com/forums/3g-rdx-problems-fixes-458/auto-high-beam-not-advertised-975370/. My wife indicated she had experienced this multiple times before. I experienced it just yesterday going about 20-25 mph on a one lane road witth a white car in front of us and cars coming in the other direction!.
Technology systems experience random failures, at various times sometimes when driving. Functionality can sometimes be restored by stopping the car and restarting the engine. Sometimes the vehicle must sit for hours with engine off to restore functionality. System failures include dashboard lighting, vehicle display screen, and heads-up display. Numerious dealer visits have provided no solution till today when I was informed that that this is a software issue and that a software vehicle update is required. However this is not available, has not been available for around 6 months and no timeline has been offered for this update. I regard this as a safety and driver distraction issue that can lead to collisions. Acura needs to place a higher priority on this issue in order to provide owners with a safer driving environment.
