Consumer Description
I had found a leak coming from my 2021 Acura RDX early November. I took it into the dealership December 1st to get it diagnosed and they stated that the transmission and transfer case needs to get replaced. du The problem has been confirmed by the Bloomington Acura dealership on December 1st 2025. After doing research online it looks like this has happened to multiple people with different Acura Models, including newer models of RDX, TLX and MDX. No warning lamps, messages or failures appeared. Just oil leaking beneath the vehicle. It looks like Acura is aware of the issue. The metal shavings from the splines between the transmission and transfer case is destroying the seal. Causing the oil leak hence a new transmission and transfer case.
