2024 Acura MDX problems

“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…”

“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.”

“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.”

“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 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.”
