Rear glass broken 2 times: 1) 12/23/2022 2) 01/31/2026.

The rear window has shattered twice (2023, 2026). Both times, the vehicle has been parked in a lot with cameras. After reviewing the cameras no one was near the vehicle. After the first time, I became aware that this was an issue with my model. I contacted the manufacturer and they expressed that my year was not affected by the defect. It just happened again. I contacted the manufacturer again, they expressed, that in order for them to do anything a recall has to be put in place and to report it to you. In addition, I do not put on the rear defrost. I have been driving around with shards of glass in the rear door. Safelite has expressed, due to how the manufacturer built the door, they can not remove all the glass. Also, every time the door is lifted pieces of glass fall out.

Came out of drs office in parking lot. Sat down in drivers seat and started the car when I heard a pop and then looked back and the entire rear window shattered.

The rear windshield shattered out of nowhere while parked outdoors on a cold day (<20 degree weather). There was no impact involved in the shattering. Dealer stated that I must go through insurance in order to get rear windshield repaired. Upon further searching this is a problem that is common with the Acura Rdx model from years 2019-2023 there was even a technical service bulletin (TSB) on may 20th, 2023 involving 'rear windshield glass shattering' caused by 'incorrect specification for the rear defroster grid' showing that the company is aware of this issue.

Rear windshield shattered while parked. It was not vandalism.

My rear windshield shattered completely on its own shortly after I had gotten in the car, I was parked, luckily I had not even started driving yet. This is a major safety component that could have resulted in a dangerous situation if I had been driving the vehicle.

To whom it may concern, I am submitting a vehicle safety defect complaint regarding my 2020 Acura Rdx. The rear window of my vehicle suddenly shattered without any impact, collision, road debris, or external force. At the time of the incident, the vehicle was stationary. There was no warning or visible damage prior to failure. The glass shattered unexpectedly, creating a dangerous condition and risk of injury. I was required to file an insurance claim and have the rear window replaced. I am concerned this may indicate a defect in the glass, manufacturing process, or vehicle structure. I request that NHTSA review this incident, determine whether similar failures have been reported, and evaluate whether this represents a safety-related defect requiring investigation or recall. I can provide photographs, repair invoices, VIN, mileage, and additional documentation upon request. Sincerely, joyce burnett phone: 757-636-6167 (mobile) VIN: 5j8tc1h57ll013150.

Sometime between 9pm on January 13th and 8:45am on January 14th, the rear glass of my 2020 Acura Rdx shattered inside our closed, insulated garage. No cause could be found inside or around the garage and I googled and found out the rear defroster grid causes stress on the class and is actually quite common. I also have a video but it’s too large to upload.

Got in my car, closed driver side door and my rear window spontaneously shattered.

Vehicle was parked overnight and woke up and the rear glass shattered. This is highly dangerous. There are tons of glass shards everywhere.

I was driving at 60 mph on the highway and the service awd light came on. The vehicle immediately lost all power and jerked and came to a sudden stop. And then when I tried to re apply power it was sluggish for about 30 seconds before I was able to get full power. I then pulled over to the side of the road and turned the vehicle on and off the error code disappeared. This happens at random times while driving the car and is extremely dangerous.

I have a 2020 Acura Rdx. In December 2022 I came out to my car and when I opened the door the entire back windshield was shattered like a piece of ice. The glass broke off into little shards all over the back of the car. Also, leaving me to drive my young daughter in the freezing cold. I had it repaired which they were able to fox the glass but not get all the shards out of the car. Yesterday, December 25l4, 2025 I went to my car which had been sitting in the garage for two days and the same thing occurred. There is glass all over my car and my garage. I have a young child and dog who could step on or touch the shards.

The rear window shattered. It is a safety issue because my window shattered as I was in a public parking lot and I had no idea. Also u had groceries in my trunk and now tiny pieces of glass was near my bags no but bulletin TSB 22-014 identified the issue.

After work, while entering my vehicle and as I close the drivers side door; the rear windshield/window shattered randomly without external force.

The rear window shattered when the front passenger door was closed. Research confirms this is a known defect and has occurred with numerous other owners, even while driving. The vehicle was taken to the dealer who refused to repair, stating my vehicle wasn't included in TSB 22-014. The vehicle VIN is included in TSB 22-014. The window was repaired out of pocket with another company. There was no warning. This occurred on 12/15/2025.

Car was in park and running idle and randomly the back windshield completely shattered. The car had been on for a while probably at least 20 minutes so it wasn’t that the window all of a sudden got really warm compared to the outside cold temperature. Had safelite replaced the window, but there are still a bunch of shards of glass in the tailgate because that would have to be fully replaced in order to remove all those glass shards and there’s no other way to do it. This is apparently a very common issue on the Acura Rdx and there is a facebook group with many people having the same issue with the rear windshield randomly shattering for no reason whatsoever. It seems like Acura dealerships acknowledge this issue, but there has been no recall.

Rear hatch window shattered sitting in driveway. This is a known issue and tons of people have reported it. There is many groups on facebook documenting the issue.

The rear window shattered when bringing it in from the colder weather to a garage. There was no impact, nor was the rear door used. The car was brough to the garage from being outside at 9 pm on 12/1. When we got in the car on 12/2 at 11:30 am, the rear window was shattered. There is no evidence of forced entry, just shattered glass on the inside. The repair is going to cost $627 the car rental is around $80.

I was just leaving from work to home as soon as I entered in my car, I saw a big hole in my rear windshield( back glass) and it seems like whole glass shattered.

I was parked in a parking lot and went to put groceries in the back cargo area. I pushed the button to open my rear hatch, heard a plink sound as it was raising, looked and my entire rear windshield had shattered. This is a known issue - Acura even sent out a notice bulletin but supposedly will only fix it free of charge if the car is still under warranty. I don't believe I should have to pay to fix this = it is a reasonable expectation to believe your windshields won't spontaneously shatter when there is no contact whatsoever.

My back window blew out, without any cause. It was parked in my driveway on a 60 degree day. There is a known issue with the 2020 Acura Rdx. There is even a service bulletin Acura issued to dealerships TSB 22-014. Acura dealership said was not covered under warranty and I would need to pay out of pocket.

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.

When I closed my passenger door my rear windshield shattered.

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.

On ?6/28/2025 my 2020 Acura Rdx rear glass shattered!!!! totally shattered!!! for no reason! no chip! no damage! it just shattered!! the whole rear glass was shattered!!!! ?.

Rear window shattered sitting idle in the driveway. Acura told me replacing would be $1,107. 00. To my knowledge they are aware of issue but not taking responsibility.

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.
