2019 Acura RDX

The front sunroof glass on my vehicle shattered without warning while the vehicle was in motion and without any impact, collision, or contact from an outside object. I had the vehicle inspected at AutoNation Acura [XXX]. The dealership's own service advisor confirmed in writing that the remaining glass "seems to be facing upward, which is an indication that it may have shattered due to pressure, as opposed to any outside influence," and stated explicitly that there was "no evidence of mistreatment/accident found during inspection." I am enclosing a copy of that email. Despite this documented finding, Acura denied my warranty/goodwill claim for the repair telling me the glass had been broken by an outside force — a conclusion that directly contradicts the dealership's own written inspection. This is a known, documented issue Acura Technical Service Bulletin 23-004 acknowledges spontaneous glass breakage as a known issue on this platform. My incident is consistent with that bulletin: no external impact, and physical evidence consistent with breakage from internal pressure rather than an outside force. I believe this points to a defect that Acura has already identified internally but is not consistently honoring at the claims level. This could have easily caused a wreck when it shattered or had the covering not be closed the glass could have injured anyone in the car and I travel with a [XXX] baby often.

I own a 2019 Acura RDX that I purchased new in 2018. It has now experienced three separate major water-intrusion events. The first two occurred while I lived in [XXX], including an incident in approximately 2021 that required an insurance claim, extensive repair, and about a month without the vehicle. The current incident occurred in [XXX]. Because the same issue has occurred in two different states and multiple times, I do not believe it is an isolated environmental event. In the current incident, I discovered pooled water beneath the front passenger-seat carpet and in the rear cargo area where the vehicle’s audio-system equipment is located. The audio system has stopped working. Before I discovered the water, the interior windows repeatedly fogged while the vehicle was parked and unoccupied, indicating excessive moisture trapped inside the cabin. The water may have been present for several days. The vehicle appears to require removal or lifting of the passenger seat and carpet to dry the underlying padding, inspect wiring and connectors, and prevent mold, corrosion, and further electrical damage. The rear cargo area and audio components also require inspection for moisture and corrosion. Prior repairs did not permanently resolve the water intrusion. The suspected source is the panoramic moonroof drain system or another water-management/body-sealing defect, but the exact source has not yet been confirmed. I am concerned that recurring water intrusion can cause electrical failures, interior mold, corrosion, loss of vehicle functions, and impaired visibility due to interior window fogging. I am requesting investigation of recurring water-intrusion complaints involving 2019 Acura RDX vehicles, including moonroof drains, drain-hose routing, drain connections, rear cargo-area water paths, and front passenger-side water entry.

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."
