The engine cooling system failed due to a coolant loss issue caused by an internal engine problem. The vehicle experienced repeated coolant loss, overheating, and was later diagnosed with a head gasket failure. The failed components were repaired/replaced by an Acura dealer and may be available for inspection upon request through repair records and replaced parts if retained. The failure created a safety risk because the vehicle overheated while driving and while idling in traffic. Loss of coolant and engine overheating could result in sudden loss of vehicle power, engine damage, or a breakdown in unsafe locations such as roadways. The issue was especially concerning because the symptoms…

I came out to my car which is parked on my driveway and went to put something in the trunk. When it opened I saw and heard things falling and looked to me like pebbles and was confused. After looking closely, my rearview window was shattered and it was pieces of the rearview glass window that was broken and was falling down. I had driven the car an hour prior and there was no windshield damage nor did anything hit my car (ie: an airborne rock). I picked up pieces of the broken glass from my driveway to prevent any punctured tires. I immediately called my local Acura dealer to arrange for a replacement. The car is currently there and the repair is going to cost approximately $1500. There was…

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…

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 vehicleâs audio-system equipment is located. The audio system has stopped working. Before…

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 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…
