2023 Acura MDX Sport looses AWD randomly and vehicle becomes only FWD. This has happened many times now and I have taken it to the dealership but they claim they can’t recreate it and would not do anything further unless I change rear end fluid.. I paid for the service but still have the problem. This is getting dangerous as it is unexpected and alters the expected performance of the vehicle in critical turning situations which has led to two close calls of a broad side accident when turning and loosing AWD. There appears to be many more reports of this exact issue, I’m officially adding my name to the list.

While driving my 2023 Acura MDX at approximately 40 mph in rainy conditions, the vehicle experienced a sudden catastrophic failure without any prior warning lights or dashboard messages. The vehicle abruptly decelerated and felt as though the drivetrain or wheels were binding / locking. The vehicle lost the ability to accelerate normally and became effectively inoperable in traffic. After stopping, the vehicle resisted rolling freely even when shifted into neutral and required towing to the dealership. The dealership has since informed me that the front transfer case / transfer box experienced a catastrophic internal failure. Root cause and failure sequence are still being diagnosed by the dealer. The sudden nature of the failure, lack of warning indicators, and apparent driveline lockup behavior created a significant safety hazard and increased risk of crash, particularly given the wet road conditions and speed at the time of the incident. There were several near misses with other cars putting me and my family at significant risk. The vehicle is currently at the dealership pending full diagnosis and repair.

The contact owns a 2023 Acura MDX. The contact stated that while driving approximately 5 MPH, the vehicle unexpectedly accelerated. There was no warning light illuminated. The contact stated that the failure had occurred on several occasions. The vehicle was taken to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 71,000.

There was a loud noise from under the car, and the car suddenly started to experience wheel spin. It's AWD and should not be spinning the tires. Suddenly losing AWD is dangerous when you expect the car to perform like an AWD car. Dealership said the transmission spline is stripped and needs replaced under warranty. Car has currently been at the dealership for 50 days. There is no known ETA on replacement parts. No warnings on anything, the car's power distribution meter still shows power going to the rear wheels even though it is not. I believe there is already an active investigation into this issue.

Unable to stop the car. Luckily no accident. Brake pedal was very hard to press and car didn't stop. Brake pedal became normal again in few seconds (5- 7 sec). Inspected car. nothing was stuck under brake pedal.
