2019 Acura RDX electrical problems

Filed Sep 7, 2026 · Electrical, Lights · CA

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.

The center infotainment display went completely black, with only the backup camera feed still functioning. There was no audio output at all (radio, navigation prompts, or Bluetooth). The dealer diagnosed and replaced the FAKRA service cables under Acura TSB B23-025, which addresses this exact display-blank/audio failure. After the cable repair, the screen remained black and audio remained completely non-functional. The dealer then determined the tuner/AV control unit had failed, confirmed by swapping in a working unit from another RDX which restored function. Acura Client Relations was contacted and declined to provide any coverage for the tuner unit replacement, stating the TSB only covers the cables themselves, despite the failure occurring immediately downstream of the covered repair. The vehicle is safe to drive but loses infotainment display, audio, navigation, and rear camera guidelines during forward driving, which is a distraction and safety concern. The vehicle remains available for inspection. No warning lamps preceded the failure; the screen simply went black."

I am writing to report an incident involving the rear window of my2019 Acura RDX that shattered unexpectedly. The incident occurred while the vehicle was parked at my workplace. I was notified by a co-worker that the rear window had shattered. Upon inspection, there was no obvious sign of a collision, vandalism, or other event that would explain the damage. A glass replacement company was called to my workplace to replace the shattered rear window. After examining the vehicle, the technician advised that there was no evidence of an external impact, such as a rock strike or other object, that would have caused the glass to break. Because the window appeared to shatter without any apparent outside force, I am concerned that this may indicate a defect in the rear glass or its installation. I respectfully request that this incident be documented and reviewed as a potential safety-related issue. Thank you for your attention to this matter.

Vehicle: 2019 Acura RDX (Technology Package) I am reporting a serious safety issue involving sudden loss of engine power while driving. On March 14, 2026, I filled my gas tank before traveling approximately 1.5 hours out of town. The vehicle operated normally that day. The following morning, during snowy and icy conditions, while accelerating in traffic, the vehicle suddenly lost power and stalled. Multiple warning lights illuminated on the dashboard (“Christmas tree” effect), and the steering became very stiff, making it difficult to safely maneuver the vehicle out of traffic. I was able to restart the vehicle, but warning lights remained on. The next day, while driving on the highway under normal conditions, the same issue occurred again. While accelerating, the vehicle suddenly lost power and stalled in traffic, creating a dangerous situation. In response, the fuel pump inside the gas tank was replaced; however, the problem persists. The vehicle continues to display warning lights and still loses power when accelerating. I contacted an Acura dealership after seeing reports of a fuel pump recall for similar vehicles, but I was told my VIN was not included. Despite this, the symptoms match known fuel pump-related issues. This defect poses a serious safety risk, especially when driving at highway speeds or in traffic, as sudden loss of power and steering assist can lead to a crash. No injuries have occurred yet, but the issue is ongoing and unresolved. I am requesting investigation into this issue as a potential safety defect.

Component Failure & Inspection: The rear windshield glass spontaneously imploded/shattered. This is a documented manufacturing defect involving the rear defroster grid, as detailed in Acura Technical Service Bulletin (TSB) 22-014. The vehicle and the shattered glass are currently available for inspection. Safety Risk: The glass shattered while the vehicle was occupied, spraying shards of tempered glass into the cabin. This posed an immediate risk of laceration and eye injury to the occupants, as well as a significant distraction/startle hazard that could have resulted in a collision if the vehicle were in motion. Confirmation: The failure was inspected and confirmed by McGrath Acura of Westmont on February 27, 2026. The dealership acknowledged the existence of TSB 22-014 and the defect in the defroster grid but has not yet provided a full remedy. Manufacturer Inspection: The vehicle is an Acura Precision Certified unit. A formal case has been opened with Acura Client Relations (Case #16209033), and photos of the failure have been provided to them. Warning Symptoms: There were no warning lamps or symptoms prior to the failure. The glass imploded suddenly and without external impact while the vehicle was stationary.

While driving in the rain, after an hour long drive home from Philadelphia back to Reading, taking [XXX] and [XXX], I accelerated my vehicle while going around 50 mph and immediately was faced with a blinking check engine light and lost the ability to accelerate. My Acura essentially went into, what others call, limp mode while in sport mode. I filled my car with 93 gas around 20 minutes before this. After losing acceleration, I pulled over on the highway and the check engine light disappeared. After which, I still was unable to accelerate after leaving the car in park. After I turned the car off and turned the car back on maybe 30 seconds later, I was then able to accelerate and found no issues afterwards.

Problem with rear back mirror defects after so long my back window shattered with no reason

The auto-stop feature on my 2019 Acura RDX has resulted in my car abruptly shutting down twice now -- today it happened when I slowed to a stop at an intersection. Basically, rather than just shutting the engine off while idling, it shuts of the electrical (dashboard and infotainment -- all systems) and engine and then immediately restarts with the car in Park. There was no warning sound or light prior to the car turning off and restarting. Obviously, it is very dangerous for a car to turn off unexpectedly, and I'm thankful that I was braking to a stop at a red light and had time for the engine to turn back on, and to put car back in Drive.
