STRUCTURE:BODY
Sudden breaking of panoramic glass on sun/moon roof. I believe this is related to the clicking noise that is caused by the improper bolting in this model. There is an active service bulletin for the improper bolting/flexing in the panoramic glass. I called the Acura dealership where this was bought and they didn’t acknowledge that. I had my two children, toddler and infant, in the back. They like the panoramic open. If this broke on top of them this would be a very serious injury.

The contact's sister owns a 2021 Acura RDX. The contact stated that the rear glass had shattered while the vehicle was parked in the driveway.

SERVICE BRAKES
After dealer (worldwide motors Ltd also call (Paragon Acura) 33-40 57th street, Woodside, NY 11377)replaced front and rear brake pads and rotors, my vehicle experienced unintended acceleration while stopped. While idling at a red light with my foot firmly on the brake pedal, the vehicle suddenly moved forward approximately 10 feet on its own. This was a serious safety concern and nearly caused a collision or pedestrian injury. I immediately returned the vehicle to the dealer. The dealer stated they could not duplicate the issue and said the vehicle was operating normally. No warning lights were present. The incident occurred immediately after brake service. I am concerned this may involve the braking system, brake booster, brake switch, or electronic throttle interaction. This behavior is not normal and poses a safety risk.

UNKNOWN OR OTHER
I had found a leak coming from my 2021 Acura RDX early November. I took it into the dealership December 1st to get it diagnosed and they stated that the transmission and transfer case needs to get replaced. du The problem has been confirmed by the Bloomington Acura dealership on December 1st 2025. After doing research online it looks like this has happened to multiple people with different Acura Models, including newer models of RDX, TLX and MDX. No warning lamps, messages or failures appeared. Just oil leaking beneath the vehicle. It looks like Acura is aware of the issue. The metal shavings from the splines between the transmission and transfer case is destroying the seal. Causing the oil leak hence a new transmission and transfer case.

VISIBILITY/WIPER
My car was parked in my driveway. After starting it up and closing my driver’s side door, the entire rear windshield spontaneously shattered without warning or any external manipulation/force. There was no way of knowing of whether or not this would happen. I fear that if I had my dogs in the car (or a child) someone could have been seriously hurt. Shards of glass went everywhere - in the trunk, all over the cargo area, and all over my driveway. I am now stuck without a car while I try to get this repair figured out. Acura/Honda needs to place a recall on this ASAP after seeing how common of an issue it is for many RDX (and other models) owners.

POWER TRAIN
The transfer case began leaking between the transmission and transfer case. Upon taking it to a mechanic I’ve been told the entire transfer case needs replacement because it has prematurely failed. The repair cost is $5533.00. Through research I’ve seen there are many failing transfer cases on acuras with the SH all wheel drive systems. I believe Acura has a design flaw in the system and should be responsible for the repair.

Complaint Summary I am filing this complaint regarding American Honda Motor Corp’s handling of a warranty claim on my 2021 Acura RDX. Despite being within the 4-year/50,000-mile warranty, I was denied full coverage for a well-documented defect: condensation/moisture in both headlight housings with no external damage. •Dealer (Rick Case Acura, Sunrise FL) confirmed the condition. •Technician Francisco documented internal moisture, no external damage. •Service Manager Wade Bell submitted goodwill request [XXX], which was approved at 70% only. •My out-of-pocket responsibility was ~$1,400. •I requested full coverage from American Honda, consistent with Acura’s warranty obligations and known issues with these headlight assemblies. On a recorded call, American Honda repeatedly stated my request was denied, refused to provide a written denial, and declined to issue a case reference number directly. Only after reviewing an email did I locate the case number ([XXX]). This refusal to document their denial is highly concerning. ________________________________________ Timeline of Events •[XXX]: Moisture first observed after rain; confirmed by dealer technician. •Dealer Request: Goodwill [XXX] approved at 70%. •Repairs Completed: Both headlights replaced; repair order available. •Sep 2025: American Honda denied my appeal verbally on recorded call; refused written denial. ________________________________________ Manufacturer Guidance Ignored Importantly: American Honda’s own dealer service bulletin (2023) regarding 2019–2021 Acura RDX headlamps explicitly instructs dealers to: •“Create an iN case number (via AcuraLink/Dealer iN) when moisture or condensation is observed inside RDX headlamp housings with no external damage present.” •“Submit for goodwill/warranty replacement of the affected headlamp assemblies.” This vehicle falls squarely within that guidance: a 2021 RDX, <4 years old, <50k miles, with moisture documented by the dealer.
