Honda (American Honda Motor Co.) is recalling certain 2021-2025 Acura TLX, 2023-2025 Acura MDX, and 2023-2025 Honda Pilot vehicles. The brake pedal pivot pin was not secured properly, which can cause the pedal to shift out of position. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard numbers 108, "Lamps, Reflective Devices, and Associated Equipment" and 135, "Light Vehicle Brake Systems."
A brake pedal that shifts out of position can prevent the driver from applying the brakes as intended, increasing the risk of a crash or injury.
Dealers will inspect and replace the brake pedal assembly as necessary, free of charge. Owner notification letters were mailed July 29, 2025. Owners may contact Honda's customer service at 1-888-234-2138. Honda's numbers for this recall are FLX and XLY.

I am reporting a potential safety defect involving the rear windshield glass on my Acura MDX. The rear windshield unexpectedly shattered while the vehicle was stationary, with no known impact or contact with an outside object. I was present when the glass shattered and immediately took multiple photographs and videos before the vehicle was moved. Based on what I observed, the glass appeared to break outward rather than from an outside object striking the vehicle. I later drove the vehicle from my home to the Acura dealership after being advised to do so. By the time the vehicle was inspected, portions of the shattered glass were understandably missing. The dealership later identified an area of missing glass as a possible “point of impact,” although I witnessed the event and there was no impact. I am submitting this complaint because I am concerned that the rear glass may have failed spontaneously and could represent a safety issue. Unexpected glass shattering could potentially occur while a vehicle is being driven and could startle a driver, expose occupants to broken glass, or impair visibility. I am also aware that Acura has previously issued technical service information regarding rear windshield glass on certain RDX vehicles shattering without external impact. I understand that my vehicle is an MDX and may not be covered by the same issue, but I believe the circumstances warrant documentation and review for a possible pattern.

Our infotainment system stopped working and when we took it one of Acura’s authorized dealers they told us that back half of the car is flooded and that has shot down all the electronics including the infotainment system. They also gave me a bill of $10K USD to fix the leak and replaced damaged electronics. Their argument is that the car was parked outside and that caused this issue. This has never come up in any of our previous maintenance visits where Acura certified dealerships always check our car and tell us that everything is okay.

AC / DEFROSTER / HVAC I am reporting a potential safety and health defect involving the HVAC system in my 2024 Acura MDX. When operating the air conditioning or the front windshield defroster, a strong musty odor enters the cabin. The dealer informed me that resolving the odor requires an EVAP core cleaning, replacement of the cabin filter, and the use of a disinfectant that will be circulated throughout the ventilation system to kill mold, mildew, and other contaminants. I was told this is the “first step” in addressing the issue and that the estimated cost is $440 out of pocket. This is extremely concerning because the presence of mold or bacterial contamination inside the HVAC evaporator and ventilation system affects the air my children and I breathe inside the vehicle. Mold exposure can cause respiratory irritation, allergic reactions, headaches, and other symptoms, especially in enclosed spaces. The HVAC system in this vehicle is a sealed, manufacturer-controlled system which the owner cannot access or service, so this type of contamination should not be considered routine maintenance. I have researched this issue and found that Honda/Acura vehicles have a documented history of HVAC mold and mildew odors, and Honda has previously issued internal investigative bulletins requesting dealers to collect parts from vehicles with musty HVAC smells. There are also mold-related complaints already filed with NHTSA for the 2024 MDX model year. This suggests the possibility of a broader engineering or design issue. I need this issue addressed immediately for health reasons, and I may have to initially pay out of pocket to ensure my family’s safety. However, I believe this is a safety-related defect that Acura should be responsible for correcting, not the customer, especially on a relatively new vehicle still under warranty. I am requesting that NHTSA document this case and consider evaluating whether a pattern of HVAC mold contamination exists in newer Acura vehicles.

Front sunroof panel spontaneously exploded while driving on the interstate highway. No impacts or other things touched the sunroof. Vehicles behind had to avoid large portions of the sunroof panel. Flying glass made it dangerous to quickly leave the highway. This is a 2024 mdx with less than 30,000 miles. Never been in an accident before.

Unknown. Constant creaking and rubbing sound when turning wheel and tires. Acura refuses to look into it more. Not a normal sound for a car less than two years old. Continues to happen everyday since two eeeks after I bought car. Have taken it to Acura multiple times for weeks at a time

Acura MDX Sunroof Explosion striking my wife face and glass going into my kids 5 and 3 car seats. The dealer nor American Honda are not taking accountability for it.

Rear storage compartment is collecting lots of moisture. This area is growing mold on the carpet and lid. Not sure if there is a faulty drain issue or the manufacturer failed to insulate this area properly causing major condensation. This is a serious health hazard concern as occupants are now exposed to mold. Vehicle is scheduled to go in to the dealership to test for water leaks 2/21/25. Until we get into the dealership, from my observation it appears to be an issue with condensation from improper insulation/engineering.

I purchased my new vehicle (2024 Acura MDX) in September 2024. On December 20, 2024, my SUV was on but in the parked position when the lights on the dashboard started flashing. I had the suv towed to Paragon Acura, where I was informed that the PCM had internal failure due to a circuit shortage. There were not any vehicle issues prior to the issues on December 20.
