Known issues on the 2023 MDX. One recall is on federal record for this model year (NHTSA 25V391000), against the service brakes, hydraulic — pedals and linkages: the brake pedal pivot pin was not secured properly, and a brake pedal that shifts out of position can prevent the driver from applying the brakes as intended. Owners have filed 53 complaints for the year and Acura has issued 126 technical service bulletins. This manual carries the factory diagnostic and repair procedures behind that system.
From a scheduled service interval to a brake pedal and linkage inspection or a hard-to-trace fault, it keeps you on the OEM procedure and the correct specification for your specific 2023 MDX.
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.

The front passenger seat weight sensor may crack and short circuit, which can cause the air bags to deploy unintentionally during a crash.

1) I was struck by a vehicle that ran the stop sign at 50mph. After the impact my vehicle continued rolling forward and wouldn’t stop. I ended up a block away from the accident and my emergency brake, brake pedal and center console brake would not engage. My vehicle was stopped after a car pulled up infront of me for me to rear end it to stop. Vehicle is a total loss and sitting in a tow yard. 2) I was in the vehicle with my 3 children under 7 years of age. Our safety was put at risk because If
I was maneuvering to park my car in a parking lot. Driving down the traffic lane of the parking lot, I slowed, braked and turned left 90 degrees into the parking space with my foot still on the brake. I reached the end of the parking space and prepared to shut the engine down. I remember looking at the shift console to find the park button when the car bolted forward. The car went over the concrete curb, clipping a tree and through bushes beyond the parking space. The car proceeded down the emba
The windshield washer fluid pump is weak and half the time does not spray when needed and left me on the highway with a dirty smeared windshield nearly making it impossible to see while driving. I understand it’s a known issue and also a new pump and reservoir is on backorder after checking with dealer.. I believe it’s a poor design and a revision should be considered as this is a safety hazard. Thank you !!
See attached document for complaint.
-Alerts for all safety systems going offline appeared. Also said AWD is not working. Car would turn off with on push of ignition. -tailgate went haywire. When opening it just went up and down and halfway. Had to push it close Both issues went away, for now, after several restarts
As slowing down to park in parking space, the automatic braking applies hard and throws you forward. All three times, the vehicle was just entering the parking space and automatically slammed on brakes causing all passengers to lunge forward and seat belt to apply hard, hurting passengers chest. This is a safety hazard as it could cause harm to the passengers and if it happens at higher speeds then could cause a rear end collision if someone is behind us when this happens. This has happened t
I have taken my vehicle to the Acura service department three times for this issue. Each time, they were unable to find a fault code or permanent fix. They have repositioned the front camera and removed an Acura sticker from the windshield, but the problem continues to occur at random. The service department said diagnostic tests show no error, yet the system still triggers false collision warnings. I’m concerned about the safety of driving a vehicle whose collision avoidance system malfunction
The interior breaking pad on the rear passenger side wheel is wearing faster than all other break pads. According to the dealership this is due to defective hold break caliper, a condition which they failed to identify and address this multiple times until a complete rear breaks job was required. As a result perfectly fine breaks have to be replaced because of a single fast wearing break pad. I am not sure if this condition can lead to any safety risks but right now there are significant repair
While driving at approximately 25 mph with no vehicle in front of me and no objects in the road ahead of me, the automatic braking system suddenly and unexpectedly engaged and brought my vehicle to a near stop. This was sudden and unexpected and the vehicle behind me nearly collided with my vehicle. It also caused my head/neck to jolt forward and while I did not sustain an injury it was a significant “jolt”. The vehicle is available for inspection upon request. My safety and the safety of oth
I bought the car in March 2023 and took the car for maintenance of 5k at Acura dealership at north Orlando and after that the car came never the same. The car is making so much noise skewing and clicking noise every time you turn the streering wheel. The dealership said the noise is from nuts and bolt and they did change it and noise became more loud 2nd time they said it is the front break and they did change it and the noise still the same and more of clicking noise with every tire turns . I d
LOSS OF POWER STEERING AND BRAKING ASSIST REDUCED. My spouse was driving our 2023 MDX approximately 45mph when she ran over a recessed manhole cover which created a bump. The MDX lossed power steering and brake performance reduced. The vehicle was very difficult to turn at that point. The car began to cycle through errors that would not clear until the car's engine could be stopped and restarted: HILL START ASSIST PROBLEM, TRAILER STABILITY ASSIST PROBLEM, ADAPTIVE CRUISE CONTROL PROBLEM, LANE K
When driving to town with family, drove over train tracks and all warning lights on dash came on and power steering was lost. I was going about 30 mpg and barely able to steer the vehicle to shoulder of road in a populated neighborhood. My wife and kids were really scared and i was glad this didn't happen in a much busier area. The warning lights were: Adaptive Cruise Control, parking brake, Lane keep assist, All Wheel Drive, electric power steering, collision mitigation, trailer stability assis
2023 ACURA MDX TYPE S. 28k miles. While merging onto highway, I sped up and at 25 mph, I heard a loud metal clunk from underneath the car. Car still drove and functioned as a two wheel drive instead of AWD. Went in for service and was told that the transmission and Power train Unit would need to be replaced and will be replaced under powertrain warranty by Acura.
Was driving arround corner and felt a shudder like I had run over something, the felt front tires loosing traction and car jerked into next lane. Took to dealer and they diagnosed a failure of output shaft from transmission to awd transfer case, currently at dealer getting transmission awd assembly replaced.
My 2023 Acura (VIN# [XXX] ) has experienced two separate incidents of sudden, total power loss while driving. In both cases, all dashboard warning lights came on, including the brake light, and the vehicle reduced speed to 20 mph and would not accelerate. The first incident occurred while I was driving on a 55 mph expressway, creating a major safety hazard. I had to maneuver to safety in high-speed traffic. The second incident occurred under similar conditions. The dealer has been unable to res
