2020 Acura RDX Complaint Log

My car was parked and off at a local park, I loaded my [XXX] son in the backseat of the car and then I got into my car. Before even turning car on I heard a loud pop sound and got out to look around and then realized it was the back windshield shattering. Apparently this is a known issue with Acura where the rear windshield will spontaneously shattered for no reason. Safety wise this is a concern since I have a child in the back seat and glass is shattering into the car as well as outside on pavement . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The rear glass in my 2020 Acura RDX Aspec randomly shattered when I closed my rear driver side door. My car was not running and hadn’t been running for over a hour and there were no signs of impact to the glass. There is a TSB from Honda about this being an issue already. I bought the car used and have owned it for a year. My extended warranty doesn’t cover the rear glass. It was going to cost over $1000 to fix as the dealership would not cover the cost and my car is out of its factory warranty. Didn’t have much choice but to use Safelite. Now there are glass shards stuck in my tailgate and apparently no way to remove them without removing the glass from the tailgate and removing the tailgate from the vehicle. Other complaints show that this can also happen while the car is running and in motion which seems like a major safety concern. With the glass shards stuck in the tailgate my car has been devalued by no fault of own. Honda knows this is an issue but will not issue a recall and it could also be a safety issue.

2020 Acura RDX Rear Coil Spring snapped in half on left side. Safety concern drove to nearest independent service center to be accessed within 5 miles of incident. Advised not to drive it. Called Acura Dealership. Advised to replace both Left and Right side and have new alignment. No warning lights or other symptoms, just an extremely loud bang to left side while driving. Estimated out-of-pocket expenses: Rear coil springs (both) 600 parts/labor Alignment required 100 Total 700 unless goodwill applies (Acura quoted and independent matched prices (allowing me not to have it towed 15 miles to dealership) This is a corrosion related rear coil spring failure at 72,000 miles in Ohio. I’m asking Acura to consider goodwill assistance because this appears premature for a critical suspension component.” Please open a good will case with Acura Tech Line/Client Relations based on: Safety-related failure (suspension spring) Salt-belt state (Ohio — well known for corrosion issues) Reasonable mileage (72,000 miles is not excessive for a structural suspension part) Dealer acknowledged the issue (they quoted it and advised not to drive) No abuse or impact damage (no tire damage, single spring corrosion failure)

My 2020 vehicle lost all power when I was attempting to pass an 18-wheel trailer on the expressway. I took it to the dealership which was less than a mile away. They told me I needed a head gasket replacement @$6500. They replaced the HG and it ran great for 5-6 months. Then exact same thing happened again on expressway. It was another head gasket. After searching online I found a lot of history on my vehicle where the 2.0L turbo engine was failing prematurely.

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.

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.

Rear windshield shattered on its own, without impact from any object

Since we bought the vehicle in 2019, the passenger-side seat sensor didn't always go off when occupied. We asked the dealership to check it out in 2020 or 2021, however, due to the problem being inconsistent it couldn't be fixed. The inconsistency of the seat sensor has continued though the years, but lately, it has become more frequent. I am the usual occupant on the passenger side and I weigh 113 lbs. I recently spoke with the dealer service department after I saw the recall; however, the recall does not apply to our VIN.

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 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.

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

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.

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.

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.

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.

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.
