When I go to accelerate to pass another vehicle car completely shuts down stops running and all warning lights come on. Car is powerless in middle of making a pass which is very concerning have to coast to side of road putting me a perilous situation hoping I don't get hit head on before I can get off the road. Took car to dealer they said bad turbo so change turbo. Two weeks after repair started to pass another car and it did it again exactly like first time. Car is currently at dealer waiting on diagnosis. I feel like this is big safety issue and I don't feel safe driving car that constantly loses power when passing someone.

Parked in a restaurant parking lot, & upon leaving got into the car closed the door and the rear window just shattered. Car hadn’t been started yet & no previous damage had happened to the window. If I had been driving the car and the horrible noise it made I probably would’ve panicked and gone off the road.

To Whom It May Concern, I am writing to formally report a recurring and concerning design issue affecting the Acura RDX — specifically, a defect in the sunroof drainage system. Based on both personal experience and widespread consumer reports, it appears that the drainage channels are prone to clogging, which results in water accumulating and eventually leaking into the vehicle’s cabin and trunk areas. In my case, this defect has led to persistent water intrusion that has damaged the interior and raised serious concerns about mold and mildew development. Stagnant water inside a sealed vehicle can pose significant health and safety risks, especially for families and those who rely on their vehicles for daily transportation. Having the drains professionally cleared at the dealership costs approximately $300 per visit. I have been informed that this service will likely be required on a recurring basis, despite the fact that such maintenance is neither expected nor common for vehicle owners. This is especially troubling considering the cost exceeds routine maintenance like oil changes or tire rotations, and it addresses an issue resulting from design flaws — not misuse or neglect. I have contacted both the dealership and Honda/Acura customer service, only to be informed that there is no permanent solution. For a vehicle marketed as a premium product, this is a disappointing and financially unreasonable resolution. I respectfully urge the National Highway Traffic Safety Administration (NHTSA) to investigate this issue as a possible design defect that compromises vehicle safety and structural integrity. Given the volume of similar complaints found in consumer forums and online reviews, it is evident that this is not an isolated incident, but rather a widespread and systemic concern that warrants further scrutiny and potential corrective action. I also have a video of water gushing inside my car which I cannot upload and it’s unacceptable. Respectfully, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

POWER TRAIN
Under full throttle acceleration while merging onto highway the car would not deliver power and the check engine started flashing. Pressing the accelerator did not make the car go. I had to pull over and stop the car. I turned it off and turned it back on and was able to drive away. Both times, the weather was very humid and I was merging on a ramp that had an uphill incline. This happened twice within a few days. The first time was on 3-MAY-2025 and the second time was on 5-MAY-2025

This was a spontaneous explosion of the rear lift gate window. The car was not even turned on; I had just gotten into it. There was a sound like a gunshot, followed by glass shattering both into and outside the car. I dropped immediately in the seat, and when I started breathing again, I got out of the car, and saw the window. Thanks to my grandson’s research, I now know this is, and has been, an issue with the Acura RDX. There. was absolutely no warning prior to this occurrence.

While my wife was driving on the highway going about 50mph, the rear window suddenly shattered without any apparent cause, startling her. Fortunately, she didn't yank on the steering wheel and was able to pull over safely. After conducting some research, I discovered that this is a known issue affecting 2019–2023 Acura RDX models and is currently the subject of a pending class action lawsuit. The window was inspected and will be replaced by our car insurance.

ENGINE, ELECTRICAL SYSTEM
While in traffic and stopped at a light, the engine stalled and completely shut down all of a sudden. I had to restart the car and was able to drive home. The engine stalled while in traffic with two other passengers in the car and during a time with other vehicles on the road. The car stalled shortly after turning a corner and other cars potentially rear ending my car due to a sudden stalling. I’m on the way to the dealership where I purchased the 2020 Acura RDX AWD brand new for a check up. The vehicle has not yet been checked by anyone but will be later today. When the car stalled, there were no warning lamps or messages. This was the first time happening but the electrical system has turned off unexpectedly before. I’ve brought the car back to the dealership for the electrical system and it was previously repaired. The new problem includes the electrical system outage plus engine stalling during traffic. Very scary and unacceptable for any car.

VISIBILITY/WIPER
My back window on my 2020 Acura RDX shattered while it was parked at school. When I opened my passenger door to put my backpack in, I heard some cracking. I walked around the front of my car and when I opened my driver's side door, I heard and saw the back window glass falling inside and outside of my car. I viewed the cameras at school and could tell the glass had cracked earlier, but believe the hole in the glass occurred from a combination of the pressure change opening my door and the vibration from shutting the door. One of my fellow teachers who came out while I was looking at the damage searched online and discovered it is a known problem for my year and model car. I called the service department at my local Acura dealership and immediately drove there. The service tech told me that he believed it would be covered since it is a known issue although my car is out of warranty. Acura posted a Service Bulletin (22-014) on October 28, 2022 that includes the VIN of my car in the affected vehicles. The bulletin states that the rear glass can shatter or break with no external impact due to incorrect specification of the rear defroster grid. The service manager called me the next afternoon to tell me he spoke to an Acura rep and they would only cover half. I am responsible for paying almost $400 to repair my back window that Acura knows is a safety issue to break since there has not been an official recall. It is not safe to operate a vehicle with a broken back window, in addition to the issues of weather exposure and not being able to secure the vehicle from others being able to access it. This repair should be covered by Acura since they are clearly aware of this issue and my car was included in the affected vehicles, even though my car is not under warranty anymore. Windows breaking are a safety issue and should be covered by the manufacturer due to their negligence.

The back window completely shattered, with shards of glass falling both in and out of the car. It is a known defect. It happened completely out of the blue. I don't understand why this isn't a recall. I also don't understand why I had to pay for a know defect. I'm grateful I was not on the highway when it happened. I was on my street but it was in a downpour.

The rear windshield of my car shattered by itself. The car had pieces of glass everywhere in the back. Acura is aware of an issue with this windshield in models RDX from 2019 to 2023. They sent a Technical Service Report (TSB 22-014) to their dealers asking to replace the windshield on these cases. We took the car to the dealer for inspection, and they took pictures showing that the car did not have any damage that could have created the problem, but they claim that Acura refuses to cover the repair anyways.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The car was just purchased Turning left going about 5 to 10mph in a 25 mph zone it hit the brakes. Then about 100 yrds later at a stop light, the car was turning left with traffic going onto a 45mph road. It slammed on the brakes, saying "brake", on the Display, causing whiplash, and almost a major accident. After calling Acura, they mentioned these driver assistance systems were tied into cruise control. When the car was tested on the highway a couple days before and used cruise control, the collision and another warning system were faulty. It said "sensor is covered or..." I do not remember the 2nd part. They specifically said if these systems are problematic with warning lights, you should not use cruise control. These cars should not be on the road. No shortage of people complaining about this online.
