2020 Acura RDX complaints

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

I am the owner of a 2020 Acura RDX. Approximately 64,000 miles. Car was parked in my driveway. My wife heard a loud bang. Back windshield shattered. Pieces of glass inside and outside the vehicle. The window had no prior dents or cracks.

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.

On January 6, 2026, as I left my house and was driving to work, I heard a loud gunshot/explosion sound. The trunk window had a whole and it started to shatter. The window completely shattered and fell. No evidence of a rock hitting the window was present. The temperature was 45 degrees. The coldness was not an issue, as this car has been in below 0 degree weather. I called Acura dealership. They told me they had never heard of this issue and didn’t offer to inspect the vehicle. I had to find a fix outside of Acura. No warning lights or prior failure issues with windows. The defroster was not on either.

The rear hatch glass exploded when the driver door was shut. Was parked outside out house in our driveway. Not driven all day.

The whole rear glass unexpectantly shattered. My Car was parked in the driveway and I found it this way later in the day. The whole rear hatchback glass was shattered everywhere. Glass pieces were starting to fall inside. I called the my local Acura dealer Bobby Rahal and they said this was problem with the RDX but Acura was not covering them. He said there is a TSB tech. service bulletin. This is a very dangerous defect that needs to be recalled.

The contact owns a 2020 Acura RDX. The contact stated upon closing the driver's side door, the rear windshield shattered suddenly. The contact stated that there were shattered pieces of glass in the rear seats of the vehicle and his daughter car seat. The vehicle was not diagnosed or repaired by a dealer or an independent mechanic. The contact related the failure to TSB Number: 22-014(Rear Windshield Glass Shattering); however, the vehicle was not covered. The manufacturer was notified but no assistance was provided. The failure mileage was 102,000.

My rear windshield spontaneously shattered with me sitting in my driver's seat in a parking lot. I just started my car, put on my seat belt when I heard this loud noise and saw the rear windshield shattered. I found no object in my car that could have caused the problem like a rock.

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.

While entering the vehicle in the parking lock, I closed the driver door and the rear view mirror shattered completely on it own.

One day last December it rained very hard for a couple of days. It about 6:30pm I got in my car to go to an appointment. There was water inside the cab, on the seats, inside of the windshield, in the dashboard and controls... and about 4 inches of water on the floor on both passenger and driver side. When I tried to start the car, all the electrical systems went haywire. Everything was blinking at me in the dashboard many different warnings and hazard lights. I took the car to the dealership for service. I was by service department told that drainage lines on the top where the sun visor is were clogged up and the water had backed up into the vehicle. This was no fault of my own. I have maintained this automobile with Acura only for 6 years, since I purchased it. This is serious, even though it was resolved by clearing the lines but the damage to the electrical system were extensive. Now that the lines are cleared who's to say this will not happen again? Will my car flood again someday? I believe this to be a design flaw and should be corrected by Acura as a possible. I believe it should be a recall, it could affect the safety of the driver and passengers. Thanks for your attention to this matter.

I was leaving noticed I could not see out of back windshield. Thought it was ice and put on the defroster. Went to scrape ice and noticed the windshield was shattered in pieces. Did not see any object around vehicle that could have hit or fell on it yo cause damage.

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.

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

Rear windshield shattered while parked. There was no accident/impact. Just spontaneously shattered.

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.

Back window shattered randomly.

On November 22, 2025, at approximately 10:30 a.m., I visited Chandler Mall and remained there for about an hour and a half. When I returned to my vehicle and began backing out of the parking space, I noticed that my rear window was completely shattered. I immediately put the car back in park and got out to inspect the damage. Pieces of glass along the edges of the window were continuing to fall. There were no signs of vandalism—no rocks, objects, or visible fingerprints. I filed a report to determine whether security cameras may have captured any incident that could have caused the rear windshield to break, but so far no suspects have been identified. I am now waiting for the replacement part and an installation appointment with Safelite. Based on others’ experiences, some people have reported hearing loose glass inside the trunk door after similar issues, which is discouraging. I am hoping to have the rear windshield replaced without further problems or risk of future shattering.

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.

Drove vehicle to work in the morning and had the front and rear defroster on (they turned on automatically due to exterior temperatures when I used autostart on my AcuraLink app). When I got to work, I parked my vehicle and had no issues at that point. But, in the afternoon when I came out to my car the rear window had spontaneously combusted. There were no obvious signs of damage, nothing on the ground that would have fallen, and nothing around. When I got home I did some searching and found that Acura is aware of this issue and had issued a TSB to fix the windows, but that they are no longer doing so under warranty. The TSB is related to the window defogger, which can apparently malfunction and overheat, causing thermal contraction/expansion to break the glass. I had glass all over the inside of my car. Imagine if I were driving it and it exploded, it could have harmed me or worse - I could have been so surprised/startled that I swerved and wrecked, possibly harming others as well. This is a disaster. There's no recall on this? There's no requirement to continue to fix a well-known problem spanning several years (2019-2023 I believe)? They are just replacing the window and apparently, some of the windows being used still have the defective defogger. I'm lucky to be alive and typing this.

Spontaneous rear tailgate shattered glass while parked. Yes, available for inspection. If I had driven the vehicle off the lot, I could have had flying glass to the vehicle behind me. Yes, the vehicle was immediately taken into the dealership & awaiting repairs. Vehicle has been inspected by Acura dealer. No, there were no signs of the problem prior to failure.

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

Information screen went dark no radio or audio

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.

1/2020 and 11/2025 rear window spontaneous broke / blew up while turning car on.

The vehicle was parked overnight safely as always outside of my home. The rear tailgate windshield shattered without warning, incident or contact. The vehicle was inspected and the windshield was replaced by an automobile window company in Maryland.

Rear windshield broke with out any impact.

While at work the rear windshield exploded. I had the workplace look at their camera's. They said that it looked normal, no one drove next to my car and it was by itself.

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

The contact owns a 2020 Acura RDX. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated. The vehicle was taken to an independent mechanic, who diagnosed that the fuel pump had fractured and failed to function as intended. The contact was advised to contact the local dealer. The vehicle was taken to the dealer, where it was confirmed that the fuel pump had failed. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 23V858000 (FUEL SYSTEM, GASOLINE). The manufacturer was not made aware of the issue. The failure mileage was approximately 53,000. The VIN was unavailable.

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.

The contact stated that the vehicle was able to restart after several attempts. The vehicle was towed to the dealer to be diagnosed several times, but the failure could not be duplicated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

When I closed my passenger door my rear windshield shattered

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 Administra

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!!!!

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.

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.

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.

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 addit

Rear window shattered while sitting parked.

The contact owns a 2020 Acura RDX. The contact stated that while the vehicle was turned off and unoccupied, the rear glass exploded. The contact stated that there was a video of the failure showing that the windshield was not impacted by any objects for the rear glass to shatter. The vehicle was taken to a glass specialist, where the rear glass was replaced. The manufacturer was notified of the failure. The failure mileage was 25,000.

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 contact owns a 2020 Acura RDX. The contact received notification of NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

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.

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.
