2022 Acura MDX Complaints

The contact owns a 2022 Acura MDX. The contact stated that while the vehicle was receiving a routine oil change, the rear wheels failed to rotate. No warning lights were illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the transmission and transfer case needed to be replaced. The contact stated that the drive shaft was moving freely while in park. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 134,984.

Took car in for oil change and service tech saw that there was transmission fluid leaking. They then found that the splines were sheared off going into the transfer case and transmission. We received new transmission and transfer case. So far everything is working. We did not get any warning that there was an issue until we took it to the dealership. Putting in the case as this seems to be a common issue on type s models.

Vehicle exhibited a fluid leak at the rear of the engine near the transmission/transfer case junction. An independent shop is currently evaluating; suspected power take-off unit failure. This matches the failure pattern described in NHTSA Defect Petition DP26001 covering 2022-2023 Acura MDX and 2021-2023 Acura TLX for interfacing spline failure between the transmission and the rear-wheel-drive power take-off unit. Separately, while pulling out into traffic, the vehicle hesitated and failed to accelerate as commanded, chugging briefly before delivering power. This nearly resulted in a collision. No warning lamps or messages appeared at any time. Whether this drivability event and the fluid leak share a cause is UNKNOWN, but I am reporting both given the open defect petition on this component. Vehicle at approximately 75,000 miles, outside powertrain warranty by roughly 5,000 miles. Manufacturer declined assistance when contacted. Component is available for inspection upon request.

The Super Handling All-Wheel Drive (SH-AWD) system unexpectedly deactivates during cold weather conditions, creating a sudden loss of traction and compromising vehicle stability control on winter roads."

The splines to the transmission and front transfer case are worn and stripped and that is causing a bad transmission fluid leak. The fix for this unfortunately is to replace the Transmission and the Transfer case assy. I am not getting any support from Acura, as this is a known problem according to the dealer. Acura is not cooperating and the cost to repair is $14,000. I noticed a transmission fluid leak, so I took the vehicle into the Acura dealership. No check engine light came on, no notification that there was a catastrophic failure occurring to my car. I've been reading that this is happening to several other Acura vehicles as well.
