SERVICE BRAKES
1. Brake Pedal Sinking to Floor While Stopped - While stopped at a traffic light or in stop-and-go traffic, the brake pedal intermittently sinks all the way to the floor despite steady pressure being applied. This issue occurs sporadically, making it difficult for the dealership to consistently replicate during service visits, but it has happened multiple times. Critically, once the pedal sinks, it does not return to its normal position on its own. I am forced to manually pull it back using my foot, which is both dangerous and unacceptable in a modern vehicle. This creates a serious safety hazard and raises concerns about potential failure of the braking system. 2. Delayed Brake Engagement - The brake pedal consistently travels halfway before the braking system engages and slows the vehicle. On all three occasions, I was told the problem could not be replicated. Despite their findings, the issue persists and poses a serious safety concern, especially in real-world driving conditions. This concern is even more urgent because I regularly transport my family, including my two toddlers aged [XXX] and [XXX] , and I need to be able to rely on the braking system to keep them safe. I have reached out to Acura on numerous occasions to report this issue, but so far, my concerns have not been taken seriously. I have not received any meaningful support or escalation despite clearly communicating the severity of the problem.

ELECTRICAL SYSTEM, STEERING, LANE DEPARTURE: WARNING
On [XXX] I headed out for an event. I had been driving for 8 minutes when I lost the ability to steer, the Brake, TSA, and Steering system warning lights flashed on the dashboard and I immediately turned onto a side street. One message stated to contact dealership immediately, DO NOT DRIVE. The car was towed to Mungenast St Louis Acura. It was scheduled for service on Monday, June 23, already, so this was perfect. It was determined the battery failed. My concern is that prior to this event the vehicle's warning system gave no indication the battery needed attention, was low in power, or anything else related to the battery. I was on a busy street however, this event could have been very much different had I decided to take the highway to my event.

The contact owns a 2023 Acura MDX. The contact stated that while driving 40 MPH, on a rough road, the "Brake" warning light illuminated, then several warning lights illuminated. In addition, the contact stated the vehicle went into LIMP Mode and failed to accelerate as intended while depressing the accelerator pedal. The contact stated that the steering wheel failed to function as intended. The contact was able to pull into a parking lot.

The contact picked up the vehicle and became aware that the "Lane Departure Warning / Drift Lane Assistance" sensor was deactivated. The contact stated that on a separate occasion, while driving 40 MPH, the failure occurred. The vehicle went LIMP Mode and failed to accelerate as intended while depressing the accelerator pedal with several unknown warning lights illuminated. The vehicle was towed to the dealer; however, no cause for the failure was found. The contact was informed that the vehicle needed two system updates. The contact was unsure if the updates had been performed. The contact picked up the vehicle and became aware that the "Blind Spot Sensor" had been deactivated.

STEERING
Incident happened on 2-JUN-2025 While driving home from work at around 45-50 mph, all of a sudden, every warning light on the dashboard illuminated, displaying various messages such as “Brake System Failure - See Your Dealer,” “Power Steering Failure - See Your Dealer,” “Road Departure Mitigation System Problem - See Your Dealer,” “Lane Keeping Assist System Problem - See Your Dealer,” and “Collision Mitigation Braking System Problem - See Your Dealer,” among others. The power steering became extremely difficult to turn, almost as if it had locked up, while the brakes were also stiff but seemed to function. The steering wheel completely locked, and I was fortunate enough to maneuver the car to the side of the road by forcing it. After turning the car off and on about three times, everything finally returned to normal on the third attempt. I immediately contacted the Acura dealership to report the issue and scheduled an appointment, feeling apprehensive about driving on the highway, fearing the problem might recur. After dropping off the vehicle, the Acura dealership diagnosed the issue, as a “Power Steering Rack/gearbox malfunction. Luckily it was covered under the extended warranty. Q.1) The components that failed or malfunctioned include the brake system, power steering system, road departure mitigation system, lane keeping assist system, and collision mitigation braking system. These components should be available for inspection upon request at the dealership where I reported the issue. Q.2) My safety and the safety of others were significantly at risk due to the sudden failure of multiple critical systems. The power steering became extremely difficult to operate, and the steering wheel locked up, making it challenging to control the vehicle. This could have resulted in an accident. Q.3) Yes, the problem was confirmed by the Acura dealership after I reported the issue and dropped off the vehicle for inspection. They diagnosed the malfunction.

FORWARD COLLISION AVOIDANCE: WARNINGS, AIR BAGS
(1) My airbag's did not deploy when an another car drove into the front of my car causing extensive damage. It has been deemed a total loss by Liberty Mutual (claim #[XXX]) and will be towed in a day or two to their salvage yard from the auto body shop. (2) Based on what I was told by the claim adjuster, body shop and police they didn't understand why they didn't deploy, especially since one of the air bag sensors was directly in front of the impact. (3) No - Acura has not been easy to communicate with and assigned me a case #[XXX] but after I answered their questions by email a few days ago they have stopped communicating with me. (4) The car has been inspected by the body shop and Liberty Mutual. (5) No INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN
We were at a stop sign. I went to hit the gas and then a warning flash on the screen that there is a problem with the rear axle of the all wheel drive and that it was switching to front drive only. During that 5-10 seconds we went through the intersection on creep mode, 2-5 mph max. I felt helpless. My wife has had it happen to her 2 times. My first experience was tonight and it could have been bad if there was a car on the road we were crossing.

SERVICE BRAKES
Brake system warning light comes on and says reduced braking take to dealer. Auto hold brakes don't always hold. Rear brakes non stop squeal and grab un predictably. I am unsure when and if the brakes will work in the rear. The loud noise from the rear squeal has caused others in traffic to flag me down and warn me something is wrong. The noise is also made it impossible to have my Autistic nephew in the vehicle with me as it triggers episodes and scares him. I have asked the dealer to please repair the rear brakes several times. They refused and instead replaced the front brakes, then admitted it is the rear brakes but refused to repair them. Honda of America also refuses to repair rear brakes. Based upon false statements on the work order the statement from the dealer is the rear brakes on the MDX are supposed to be like this. This vehicle has issues with the warning light while stopped and moving, and the noise and unsafe braking is at all speeding from 1-60 mph. Forward and reverse is malfunctions. I asked Honda America to repair which they won't then I ask them is the official statement these brakes are okay and safe as is and they will not say that either. I have driven similar models of this vehicle and it does not do the same thing, no noise, or warning lights, and the brakes preform safely and consistently. Mine do not. Honda of America does not want to repair the brakes under the warranty. They also incorrectly stated on repair statement that humidity and car washes can make the brakes do this. I have been in northern non humid states during winter and never use a car wash. They just use this as an attempt to not repair the brakes.

ELECTRICAL SYSTEM, STRUCTURE:BODY, STEERING
I have attached all my service records from Honda/Acura and the dealership Motorworld which is located in Wilkes Barre, PA I had my first issue with the car in January 2024 with sensors malfunctioning. They we replaced a few times, repeated issue I had other issues that didn't replicate themself or show as an error code when I brought the car in. Issue accelerating or inability to accelerate on the highway in a middle lane w/ a tractor trailer on each side. One trying to merge into my lane. Noisy brakes, low breaks etc Fast forward to March 2025, my number one complaint about these sensor issues is they would malfunction on me one day when I was driving. And I was always assured by the dealership it was good, the car was good, I was good. Acura felt the same. Well in April my steering malfunctioned while driving, the steering wheel locked as I was breaking for a red light, and I drifted off the road. Turns out my steering rack needed to replaced. It was fixed on 4/4 then on [XXX] with my children in the car, it did the same thing. Now they tell me it is the EPS, electric power steering. This car spends more time on [XXX] and one day this is going to happen on the interstate and there will be fatalities. I have been screaming at Acura and the Motorworld for months. Acura will not respond to emails (which I have kept) and every time I call the case manager assigned to me is not available. The few times months ago I did speak to someone they tell me the same things the automated email I get once in while that say my case is under review. All dates of occurrence and repair are in the service records I attached. They still have my car today, 5/8/25 so I do not have those to attach.

STRUCTURE:BODY
Bought the car brand new, at only 10k miles, found out that the fender liner is falling off from the frame. During the rain, it gets heavier and pulls further down. Eventually fabric will fall off and will hit the tire while driving and possibly cause an accident. Tried to get it fixed by Acura dealership but they're saying it cannot be fixed because it's manufacturing defect.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was pulling into a friend’s driveway. I had my foot on the brake was barely creeping forward. Without any yellow warning, the car slammed on the brakes for me. It hit the brakes so hard, I had smoke coming out of my front, middle vents and when I got out of the car, it smelled very bad and I had smoke coming from my brakes. There was nothing in front of me. The same incident also happened to my husbands few days earlier while he was pulling into our garage.

I was stopped at a traffic light and my car just shut off for no reason. I had to keep trying to start it but it wouldn't turn back on. I finally got the car to completely turn off, sat a couple minutes and then restarted it. Thankfully I was able to get it back on before the light changed again.

UNKNOWN OR OTHER
I have had a on going issue with using the touch pad which controls the GPS navigation , mobile phone and FM & XM radio operation. Trying to use any of these while driving or even when the vehicle stopped on the side of the road is very dangerous . The display screen is not a touch screen like most vehicles. Only the driver can select options using the touch pad which is located between the passenger and drivers seat console. It's a very dangerous distraction as you have to spell out letters using your finger to find a location while using the navigation system . Also the pad is so sensitive it makes you repeat the letter over and over in order to find the location you are trying to type in. Also something as simple as changing the FM or XM radio station requires you to use the touch pad . While trying to use the touch pad it forces you to take your eyes off the road to operate the system. The same issue with the mobile phone which is controlled by the touch pad when connected. I understand the newer models have went back to a touch screen operation. I've complained to Accra customer service as has others , but they haven't taken any actions to correct the problem. Most owners of these vehicles are families with children and senior citizens. Hopefully the NHTSA will investigate this very dangerous situation and require ACCURA to replace the current system with a touch screen operation or the option to have both .
