2024 Acura MDX Problems

The vehicle is showing LOW SPEED BRAKING CONTROL and BRAKE SYSTEM PROBLEMS, it is also throwing DTC Codes B2600-97; B2627-96; B2630-96; B2637-11; P2583-76 and P2583-97, as I consider the vehicle unsafe to drive or operate and it is a leased vehicle I took it to the same Acura dealer I leased the vehicle from, in order to have it repaired and put back to a normal operating status and make it safe to drive and operate. I took it to the dealer, advantage Acura of Naperville, on Friday October 9, 2026. The dealer is refusing to repair the braking failure under the manufactures warranty, as the vehicle only has 31thousand miles on it, and it still is within the manufactures warranty period.

The contact owns a 2024 Acura MDX. The contact stated that while driving approximately 20 MPH and driving over construction steel plates on the roadway, the brakes independently engaged while the accelerator pedal was depressed. The contact stated that the failure could have caused a rear-end crash while driving at faster speeds with other vehicles nearby and posed a risk to her 1-year-old child seated the car seat in the second-row rear seats. The BRAKE warning light was illuminated. The manufacturer was made aware of the failure by telephone. The failure mileage was approximately 21,642.

VIN: [XXX]: 2024 Acura MDXComponents: Engine, Electrical System, Powertrain (Auto Idle-Stop)Ref Investigation: NHTSA EA25-004 (Upgraded from PE22-005) Dealer: Acura Carland ([XXX])SAFETY DEFECT SUMMARY:Severe safety hazard involving the Auto Idle-Stop system. The vehicle repeatedly shuts off at stops (intersections, traffic lights) and fails or struggles to restart, leaving it stranded with zero motive power in active traffic and creating immediate collision risk. DEALER FAILURE & PROTOCOL DEVIATION:Under warranty, Acura Carland diagnosed excessive starter electrical draw and replaced the starter motor. This was a superficial fix. Per Honda/Acura technical directives (e.g., TSB 23-009 / NHTSA [XXX] and [XXX]), high starter current draw during idle-stop restart stems from root mechanical drag (valve clearances) and faulty relays. Replacing only the starter ignored the root cause, leading directly to repeat failure.The identical failure recurred. Upon returning to Acura Carland, dealership personnel dismissed my concerns, disregarded published technical notices and federal investigation references, and refused to escalate to Honda Technical Information & Support (TIS) or a Field Technical Specialist.NHTSA EA25-004 NEXUS:Directly matches active investigation EA25-004 (2.2M Honda/Acura 3.5L vehicles). ODI specifically noted restart failures persist even after software updates and starter motor replacements. My vehicle demonstrates that 2024 MDX models suffer the identical vulnerability and dealers are performing inadequate component swaps. RELIEF REQUESTED:Incorporate VIN [XXX] into EA25-004.Mandate American Honda enforce root-cause dealer repair protocols (valve adjustments, starter relays).Compel a safety recall and full warranty extension covering all Auto Idle-Stop, ignition, valve train, and starter components.

The windshield on this 2024 MDX must be replaced because of the rear view mirror coming loose from the windshield. Acura is dragging their feet on correcting this dangerous situation of preventing the ability to see or use the rear view mirror.

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.

2004 MDX had digital screen problems where the screen remained black upon starting, which was hazardous as I couldn’t tell how fast I was going. After 3 visits to the dealership they identified the problem and fixed it Also, in a separate instance, car stalled after trying to start up after stop signs or while waiting in traffic several times. Could have been rear ended or worse. Dealer replaced the starter at 30k miles. Still had the same issue after this and they say the car is fine.

I was driving in the far right lane on the Van Wyck Expressway when suddenly my steering wheel locked up on me along with the following error messages displayed on the odometer: 1. Collision mitigation braking system problem. See your dealer 2. Road Departure mitigation problem. See your Dealer 3. Low Speed braking control problem. See your Dealer. 4. Electric Power Steering problem. Steering assist not available. Do not drive. 5. All wheel drive system problem. Only front wheels may be powered. See your Dealer. 6. Brake system problem. Brake performance may be reduced. See your dealer. 7. Brake hold problem. Apply brake when stopped. See your dealer. 8. Vehicle stability assist system problem. Reduced traction and handling. See your dealer. 9. Hill start assist problem. Vehicle may roll upon brake release. See your dealer. Thankfully I was approaching an exit ramp and I was able to steer my MDX safely off the expressway. I parked my car on the service road, turned my hazards on and then turned the car off. When I restarted the car the error messages were gone and power steering worked as if nothing happened. Acura will be hearing from me I could’ve been in a serious accident.

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.

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

When cruising or coming off a stop, my car is incapable of accelerating promptly if I am trying to get out of the way or even merge into oncoming traffic on a highway. There is a severe acceleration delay perhaps with the throttle body. I have seen online complaints but the dealership said there has to be an actual recall number to correct this. My car has been in several times to fix this. A computer reset did not work. My car is one year old.

The contact owns a 2024 Acura MDX. The contact stated the messages "Parking Sensor Failure - See Dealer", "Brake Performance Failure" and "Brakes May Be Reduced - See Dealer" were displayed. Additionally, the Forward Collision Avoidance sensor would alert the contact of a potential collision erroneously. The vehicle was taken to the dealer, where the computer systems were reset, and the front bumper sensor was replaced. The contact stated that after the repair, the auto brake hold feature failed to engage upon coming to a stop and releasing the brake pedal, causing the vehicle to roll. The vehicle was taken to a second dealer, Kearny Mesa Acura (5202 Kearny Mesa Rd, San Diego, CA 92111); to be diagnosed, but the cause of the failure could not be determined. The contact also noticed that the wheels were out of alignment. Additionally, the contact stated while driving at various speeds, the vehicle surged forward and felt like the transmission had shifted from 1st to 3rd gear instantly, and the failure recurred while decelerating to come to a stop. The contact stated while driving approximately 5 MPH in a parking lot, the vehicle suddenly felt like the transmission was in 3rd gear. The contact immediately depressed the brake pedal and stopped the vehicle. The vehicle was taken to a third dealer, Acura of Escondido (1502 Auto Park Way N, Escondido, CA 92029) to be diagnosed, but the cause of the failure could not be determined. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failures and a case was filed. The failure mileage was approximately 9,747.

Vehicle will suddenly shut the engine off and shift into park, even when the auto engine shut off is not active. Typically happens when stopped at a stop light. You will feel the engine shut off, and the car shift into park. It is very scary and unsafe. It has also caused the vehicle to shut off and shift into neutral while it was moving, and the vehicle gave a transmission warning. It sounds very similar to NHTSA Recall 25v-031, however, my vehicle was not included in the recall as it is not a Type S. I took it to the dealership and they said that Acura has opened an investigation due to the number of complaints, but there is no solution yet. I have not other option but to dry the vehicle, but I am worried that it is unsafe and not good for the vehicle to keep stalling the way it is.

The contact owns a 2024 Acura MDX. The contact stated that while driving at an undisclosed speed, a loud banging sound was heard coming from the vehicle.

The vehicle was taken to the dealer; however, the failures could not be duplicated. The vehicle was not diagnosed or repaired. The dealer was also contacted regarding the shattered sunroof; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 29,112.
