On July 12, 2025 my husband, the driver, and myself, owner of the vehicle and passenger this day, were driving on the freeway at approximately 7:00am in the middle lanes of the freeway. Without any codes or warnings beforehand, we heard the car make alarming beeps and automatically loss all power to the engine while traveling at highway speeds. This situation put my husband and my lives at risk and in a dangerous situation as there was traffic on a busy freeway and lost all power to the vehicle and made even maneuvering off the freeway a dangerous action as we had no warning beforehand there was something wrong. My husband was able to get us safely out of harms way. After being diagnosed at a mechanic, it turns out this problem happened due to a cracked cylinder head and had no previous warnings of an issue and no warning lights on the vehicle alerting to a problem, I will have the cylinder head in my possession and the mechanic I took my vehicle stated it cannot be ruled out this could be a manufacturer-??s or casting defect. I tried contacting Acura Corporation about this situation but was told that since I did not take it to a dealership and have a certified tech look at my vehicle, there will be no case and no type of remedy or reimbursement for this situation.

I am writing to formally bring to your attention a recurring and concerning design issue with the Acura RDX involving the sunroof drainage system. This problem appears to stem from a flawed design in which the drainage channels frequently become clogged, leading to water accumulating and eventually leaking into the vehicle-??s cabin and trunk areas. In my personal experience, this defect has resulted in persistent water intrusion that not only damages the interior but creates a serious risk for mold and mildew growth, along with unpleasant and unhealthy odors from sitting water. The accumulation of stagnant water inside a sealed vehicle presents a clear health and safety concern, particularly for families and daily commuters. The cost to have the drains professionally cleared at the dealership is approximately $300 per visit. I have been advised that this cleaning will be an ongoing necessity, despite the fact that this type of maintenance is not commonly expected of vehicle owners as part of standard upkeep. In comparison, this expense surpasses the cost of regular oil changes or tire rotations -?" yet it addresses a problem that stems from the car-??s design rather than from use or neglect. I contacted both the dealership and Honda customer service and was told there is no permanent fix for this issue. The best they could offer was to cover 50% of the cost for a temporary solution -?" drain cleaning -?" which does nothing to resolve the root design flaw and will inevitably need to be repeated. As a consumer who has invested in a premium vehicle, I find this resolution to be unacceptable and financially burdensome. I respectfully request that the NHTSA investigate this matter as a potential defect affecting vehicle safety and integrity. Given the number of similar complaints circulating in consumer forums and online reviews, it is clear that this is not an isolated incident, but rather a systemic problem that deserves further attention and possible action.

This safety issue is the sunroof glass. I was driving when the sunroof glass exploded and shattered, without warning. The sunroof itself and the shade underneath were both closed. The shade is the only thing that kept the shattered glass from falling into the vehicle and onto me. If the shade had been open, the glass would have fallen on to me and any passengers, possibly causing injury or death. The sound of the explosion alone is enough to cause panic, stress and impaired driving, putting everyone on the road in danger. The shattered glass was blowing off of the vehicle and onto other vehicles behind and those traveling the other lane. The past few days have been extremely hot. That is the only outlier that I can pin point, that may have caused stress to the sunroof. The vehicle sits under a carport at home and when I'm at work it is parked in an open parking lot. I was driving home from work after making a few stops, again, on an extremely hot day, Monday, June 24, 2025. There have been record-breaking heat days during this week. As I looked at the exploded sunroof, I can tell that the the glass exploded out/up instead of anything pushing the glass down. I did not call the police. I did call Honda/Acura customer service to file a complaint. I filed an insurance claim; which is still going to cost me $1,000 deductible to repair. My insurance has referred me to Safelite Solutions. The vehicle is available to view now and until it's able to be repaired; which I'm working on now.

On or about March 10, 2025, I brought my vehicle to Acura of Ocean in Ocean Township, NJ. My infotainment center was crackling continuously, and the screen was black, rendering my navigation system, radio, clock, and Apple CarPlay unusable. The constant crackling, with the screen downloading graphics, and various messages popping up, such as "check tuner" and "network connection lost, " is a constant distraction and annoyance while driving. I have no choice but to use my iPhone, forcing me to take my eyes off the road. The dealer inspected the car and informed me that my amplifier and tuner had water damage from a leak on the tailgate top seal. I paid Acura $258.71 to have the seal replaced. I was told the seal caused the water damage and was given an estimate for $3339.09 to replace both components. I contacted Honda of America because I had learned of a recall of 2019 Acura RDXs for this precise problem. The case manager of Honda got back to me and informed me that Honda of America offered to pay all but $1366.93 to replace the components. I refused the offer because I do not see how I should be liable for any cost. It remains unclear why my VIN did not appear during the recall and why I received no notice of said recall. I strongly feel that Honda's offering me any money is an admission of responsibility/guilt for this problem. If there were no liability, Honda would have offered nothing. I hope to receive communication back from your agency advising what I should do in order to have Honda recognize and admit their error and make good on the repair. Thank you, and please help!

Rear window shatters without any warning can be extremely dangerous when happens while driving due to it sounding like a gunshot I can be severely distracting to driver causing the driver to lose control of vehicle or swerve into other lanes and injure other drivers. Incident occurred twice nice in November 2023 and a second time February 2025

On 12/21/24 I was driving down the mountain into town when I heard this very loud noise, like someone threw a baseball at my truck. I was startled and shaken up. Glanced in my rear view mirror and saw my rear windshield had exploded. When I was able to pull over to inspect it, the window imploded into the back of my truck. Drove directly to Safelite. Told to go through insurance which I did. Windshield repaired on 12/24, paid for by insurance. Found out in the meantime that Acura had an issue with 2019-2023 RDX exploding rear windshields due to a possible faulty rear defroster. I had just turned on my rear defroster before this happened to me. They issued a TSB to dealerships. I never got a recall. Contacted Acura for insurance reimbursement and wanted to have my electrical system checked at their expense. After several conversations, I was denied. Case was closed last week. Although my vehicle was a 2019, my vin was not included in campaign. I also was not privy to what the exact recall said as my vin was not included. I was told I should-??ve brought it to a Honda dealer for inspection and repair. Why would I do that when I didn-??t know there was an Acura issue? I live in the Adirondacks where it snows every day. Time was of the essence. Now I will not use my rear defroster in fear it may happen again. I also will not use my heated seats as I am afraid there is an electrical issue. I can live without the heated seats but driving without a rear defroster in the North Country is not exactly safe. I had asked for them to broaden their recall as it was obvious the same thing happened to my truck but was denied. I have googled and found there a quite a few people who this has happened to, one woman has it happen twice within three months. I feel this is an extremely dangerous issue that Acura will not take accountability for. I also have not had recall done as the nearest dealer is an hour away. Acura will not allow me have have it done by Honda dealer 20 min away.

Rear windshield glass unexpectedly shattered while I started it up inside the garage

- Cicero, IL, USA

THE BACK WINDOW OF THE RDX RANDOMLY SHATTERED. I HAD JUST FINISHED PUMPING GAS, CLOSED THE DOOR, AND THE WINDOW SHATTERED. I HAD TO DRIVE HOME WITH A HOLE IN MY BACK WINDOW WITH GLASS FALLING AS I DROVE. I TOOK IT TO THE DEALER AND WAS TOLD BECAUSE MY CAR'S WARRANTY HAD EXPIRED, I HAD TO PAY $1200, AND I HAD TO WAIT SIX DAYS BEFORE IT COULD BE FIXED. HOWEVER, I WAS TOLD THIS IS A MANUFACTURER DEFEAT THAT HAS TO DO WITH THE DEFROST SYSTEM. THE DEALER NEVER LOOKED AT THE DAMAGE. I HAD TO GO THROUGH MY INSURANCE COMPANY. THERE WAS NO WARNING THAT THIS WOULD HAPPEN. I HAD TO GO ONLINE TO GAIN KNOWLEDGE THAT THIS IS A RECURRING ISSUE WITH RDXs from 2019-2023. I SHOULD NOT HAVE TO PUT OUT ANY MONEY FOR WHAT IS AN ACURA DEFECT.

My car was parked when my rear windshield shattered. I drove my car to the dealership and they said they will file a claim and wait for a response.

- Sicklerville, NJ, USA

It is about 50 degrees clear, with no rain. I drive onto the highway and hear what sounds like a gunshot. The Rear window explodes, and then glass flies all over the car; I roll down my window, and then glass goes everywhere, and all my stuff in the car flies around. I pull over and assess; this is the same thing that happened to me last year. The window randomly exploded. I called my insurance company, and they replaced it, but now the glass is stuck in the door. I called three 3 Acuras, and they all mentioned they hadn't heard of the issue until I mentioned the bulletin; now they say they have heard of it before but don't know if there is a way to help. Primary safety concern and a bit of a coverup by Acura
