Incident Description: Spontaneous Rear Window Shattering On the night of August 28th, 2026, my 2025 Acura RDX was parked legally in my apartment complex's residential parking area. There was no severe weather, falling debris, or external activity in the area. When I returned to the vehicle the following morning on August 29th, 2026, I discovered that the rear windshield glass had completely shattered and collapsed inward. There are no impact marks, points of contact, or signs of forced entry, indicating that the breakage occurred spontaneously due to a known structural stress or manufacturing defect. I contacted 3 local Acura dealerships about this ongoing manufacturing defect and even mentioned the TSB-22-014 number issued by Acura for this specific issue. However, the service managers/technicians at all three dealerships insisted that this issue was only for older models (2019 and 2020), and has been fixed for newer models. All three dealerships refused to even do an official inspection of the rear windshield glass shattering to confirm that it was a manufacturing defect, leaving me to fix the glass myself. I had the rear windshield glass replaced by Safelite, and filed a reimbursement request case with Acura Corporate. Luckily, this happened while my car was parked and with no one in the vehicle. However, this could pose a massive safety risk, as it could easily happen with people in the vehicle while the car is being driven and could potentially cause injuries to the car passengers if this manufacturing issue is not addressed immediately.

I am reporting recurring water intrusion into the driver-side passenger compartment of my 2020 Acura RDX following significant rainfall. This has occurred multiple times. The most recent incident occurred on August 28, 2026, following heavy rainfall. Water entered the vehicle and accumulated on the driver-side floor, leaving the interior floor in a puddle. I documented the water intrusion with photographs and video and submitted that documentation to my automobile insurance company as part of a claim. The vehicle was not being driven through standing water; the intrusion occurred after rainfall while the vehicle was parked. The vehicle has previously been inspected by North Park Lincoln of Dominion, where I purchased the vehicle. Despite the prior inspection, the vehicle has continued to experience water intrusion into the driver-side cabin following significant rainfall. The recurring water intrusion raises concern that the panoramic sunroof drainage system may not be adequately draining or preventing water from entering the passenger compartment. Water entering the cabin can reach wiring, electrical connectors, control modules, and other electrical components located within the vehicle and could potentially cause electrical malfunction or other unsafe conditions. The most recent water intrusion is documented, and the vehicle and affected components are available for inspection upon request. Photographs and video documenting the August 28, 2026 incident were provided to my automobile insurance company. I am reporting this because the water intrusion has occurred repeatedly and I am concerned that this may represent a recurring safety-related defect with the 2020 Acura RDX panoramic sunroof drainage/water management system rather than an isolated incident. There were no warning lamps or messages specifically preceding the August 28, 2026 water intrusion. The primary symptom was substantial water accumulation on the driver-side floor following rainfall.

I am reporting recurring water intrusion into my 2020 Acura RDX following significant rainfall. The first water intrusion resulted from heavy rainfall in April 2026. I did not discover the water inside the vehicle until May 1, 2026, when I found water accumulated on the driver-side floor. I filed an insurance claim after discovering the damage. Following the May 1 discovery, Gunn Acura, where I purchased the vehicle, inspected it. The dealership found the panoramic sunroof drainage system had a kinked/clogged drain line that was not properly allowing water to drain. The dealership also identified corrosion affecting wiring harness components and recommended repairs including replacement of the moonroof drain tube, carpet removal/cleaning, and replacement of affected wiring harnesses. Following another heavy rainfall on June 15, 2026, water again entered the vehicle. The water intrusion has resulted in electrical concerns, including warning messages and electrical abnormalities. Water entering the cabin can reach wiring, electrical connectors, control modules and other critical electrical components, creating a potential safety risk. The vehicle and affected components are available for inspection upon request. I have dealership documentation of the kinked/clogged drain and recommended repairs, as well as insurance documentation related to the water intrusion. I am reporting this because a failure of the panoramic sunroof drainage system has resulted in repeated cabin water intrusion and potential damage to critical electrical components. I believe this may represent a recurring safety-related defect rather than ordinary water leakage.

ENGINE, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
The vehicle’s keyless access/security and body control system malfunctioned. An authorized Acura dealer previously diagnosed water intrusion from blocked panoramic sunroof drains, including water reaching the Body Control Module (BCM) Multiplex Control Unit. The dealer reported that this was causing false security alarm activation and battery drainage and recommended BCM replacement. The vehicle and affected components are available for inspection upon request.The condition has since escalated. The security alarm repeatedly activated without cause and became difficult or impossible to silence. The dashboard displayed, “Keyless Access System Problem\. See Your Dealer.” During the latest episode, the engine spontaneously started without an authorized remote start command, and attempts to stop the engine were unsuccessful. The 12-volt battery was therefore disconnected to disable the vehicle and will remain disconnected until the vehicle is taken to the Acura dealership for diagnosis. This created a safety risk because the vehicle demonstrated unintended engine operation and loss of normal control over engine shutdown, creating potential risks of unintended operation, exhaust carbon monoxide exposure if this occurred in an enclosed area, and battery depletion. The dealer has confirmed the water intrusion and BCM security system malfunction. However, the unauthorized engine start and failure to shut down event occurred after that diagnosis and has not yet been evaluated by the dealer. Before the unauthorized start, symptoms included repeated false alarms, battery drainage, documented water intrusion, and the Keyless Access System warning. The warning was photographed at approximately 81,416 miles during the same period of escalating electrical security problems.

SERVICE BRAKES, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
Two low-speed sudden unintended acceleration events while parking a 2021 Acura RDX. Incident 1 (July 2026): While parking at low speed, the car unexpectedly surged forward. Flew up the curb and hit a restaurant window, causing massive undercarriage damage. Active braking did not help and seemed to make acceleration worse. It only stopped when it wanted to. Incident 2 (August 2026): Two weeks after getting the car back from repairs, under identical low-speed parking conditions, a second sudden acceleration event occurred. Slamming on the brakes did nothing. It stopped after scraping a car wash vacuum pole, destroying the entire passenger side. Prior to these, the car exhibited erratic safety software behavior, including multiple phantom braking incidents where it slammed on its brakes violently with no obstacles present. I bought the car Certified Pre-Owned two years ago. The dealership repaired a known "popping sound" from the panoramic sunroof frame three times. This required extensive cabin/pillar teardown work, which may have disturbed internal wiring harnesses or grounding points linked to the electronic throttle control system. In both events, it felt like an uncontrolled amusement park ride—the engine loudly revving and taking over with zero driver control. I initially assumed pedal confusion during the first crash, but since it happened again under identical circumstances, there is clearly a systemic electronic/software defect in the Throttle Actuator or Powertrain Control Module. The vehicle is at an insurance network body shop awaiting forensic evaluation of the throttle system, pedal sensors, and a Bosch EDR black box download.

ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
My RDX experienced a water-intrusion failure involving the panoramic sunroof drainage system and associated electrical components. An authorized Acura dealer diagnosed the right-front sunroof drain as backed up/overflowing, allowing water to reach the Body Control Module (BCM/Multiplex Control Unit). The dealer attributed abnormal security-alarm activation and battery drain to the water-damaged BCM and indicated that the BCM required replacement. The dealer also identified a blocked right-rear sunroof drain that allowed water to reach the tuner, causing radio/stereo malfunction and requiring tuner replacement. The water intrusion reached critical electrical components and caused unpredictable electrical behavior, including unexplained security-alarm activations, exterior lights remaining illuminated, complete battery discharge, loss of keyless access, and ultimately a no-start condition that rendered the vehicle inoperable. After the battery was depleted, I had to use the manual key to enter the vehicle. This created a risk of being stranded and raised concerns about the reliability of the vehicle’s electrical systems. There were no known dashboard warning lamps or conventional warning messages before the failure. AcuraLink recorded unexplained security-alarm activations on August 16, 2026, at 10:27 PM EDT and again on August 19, 2026, at 10:51 AM EDT. During the overnight incident, the alarm activated and the exterior lights remained on until the recently replaced battery was completely discharged. The car also experienced radio/stereo problems traced by the dealer to water reaching the tuner, and water was present in the passenger-footwell area. My car was inspected and the problem confirmed by an authorized Acura dealership. The car is available for inspection and available upon request.

POWER TRAIN
Prior to the 5,000 mile oil change, I experienced at least five transmission shifting issues and reported the problem to Bergstrom Service Department. They test drove it and found no issues at that time and could not repeat the shifting issues while I was there. From what I have observed, the engine will rev up to a high rpm but will not shift automatically. You then have to pull over to the shoulder of the road and decelerate the engine until it will shift gears properly at a slower speed. Not only is there a flaw in the transmission but there is a safety concern when accelerating from a stop sign or merging onto a freeway. I fear getting into an automobile rear end accident from a transmission malfunction. Since the 5,000 mile service, we have experienced one more engine rev shifting issue.

I have been experiencing issues with the alarm system when I lock the car the alarm randomly goes off. I have had my battery replaced and it still happens. There is nothing touching the handles during these times, it happens randomly, something internal going on. The only way to be sure it won’t disturb my neighbors is to leave my door unlocked which is unsafe.

UNKNOWN OR OTHER, ELECTRICAL SYSTEM
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."

EXTERIOR LIGHTING
The HID low beam headlamps are not putting out enough light to drive the vehicle at night. This is dangerous, and I drive home from work at night. The inner low beam lens has degraded and become hazy. This would require the entire headlight housing to be replaced, which are very expensive - about $1,700. I believe this is the same problem that 2015 Acura RLX are experiencing, and recall JN2 was created. I don't understand why the 2015 Acura RDX models weren't included in that recall.

POWER TRAIN
I own an Acura RDX that experienced a sudden failure of the transfer case. Prior to the failure, there was little or no warning that a major drivetrain component was about to fail. When the transfer case failed, the vehicle lost its normal all-wheel-drive operation and required expensive repairs. I believe this is a safety defect because the transfer case is a critical drivetrain component. A sudden failure can reduce traction and vehicle control, especially when driving at highway speeds or on wet, snowy, or icy roads. Drivers may not expect the loss of power to the rear wheels, which could increase the risk of skidding, loss of stability, or being unable to safely accelerate into traffic or avoid a hazard. In addition, there are numerous reports from other Acura RDX owners describing similar transfer case failures, suggesting this may not be an isolated incident but a recurring problem. A critical drivetrain component should not fail prematurely under normal use without adequate warning. I believe this issue warrants investigation because it has the potential to affect vehicle safety and place drivers and passengers at unnecessary risk.
