The vehicle's all wheel drive system has malfunctioned at 77,000 miles with a known all wheel drive system issue. Because we are 7k beyond the power train warranty, Acura is not wanting to cover the repair even though this is a known issue.

Reporting an additional case in support of ongoing defect petition investigation DP26001. 2022 Acura MDX Type S SH-AWD, currently at 63,700 miles. While driving and making a turn, I heard a grinding noise with no warning lights illuminated. I stopped immediately and shut off the engine but noticed no abnormality. I restarted the vehicle and drove with no further issues or noises. Later, during a scheduled oil change, I discovered that the area between the transmission and PTU was covered in oil. The Acura dealership diagnosed a bad PTU seal and replaced the PTU under powertrain warranty, but completely disregarded my concern regarding investigation DP26001 and the known issue with stripped…

Under medium acceleration vehicle shuddered a lot. Currently itâs only driven by the front wheels and it will torque steer a lot. Iâm assuming my splines are stripped to transfer case. Thankfully, I am under warranty and Iâm going to get this repaired.

Drove till I got off the highway at a red light I hit the gas and noticed the front wheels was spinning and realized it wasn't a awd. Took it the dealer and they realzied the driveshaft was spinning by hand.

The component that malfunctioned was the transfer case, the vehicle was already repaired so an inspection isn't possible anymore. The vehicle behaved as normal until the accelerator was pressed enough to make the front wheels lose traction, in which the vehicle couldn't send power to the rear, because the transfer case was shredded up. When needing to accelerate quickly in traffic, the vehicle would completely spin up the front tires, not being able to put the power down. The dealer reproduced the problem, but initially stated that it was most likely due to the salt on the road (it was winter). As spring arrived, the problem still persisted, in which the dealer checked the transfer case and…

I own a 2022 MDX Type-S. I recently read about complaints about TLX and MDX models losing their AWD system and only resulting to FWD. I was a victim of this in Montana and it was a long fight with Acura / Honda to look at the problem. It was also very dangerous as I worked up in Big Sky and would rely on the AWD system in snowy conditions. This system would always fail. After a long fight, they finally towed my vehicle back to Salt Lake City, where it was purchased from, and replaced a "sensor."

Starting hearing issues late 24 of MDX and TLX losing all-wheel-drive due to splines stripping between the transmission and transfer case. Had car thoroughly inspected and fluid samples taken in December of 24. In February on 25 with a frame rattling bang as I was pulling out onto a street, rear wheel drive went out at 64k.

New transmission is two parts number newer than original and transfer case is one parts number newer than…
