“We purchased our 2022 Acura MDX with 7K miles on it. The transmission failed 2 years after it was purchased and required a full replacement. We knew there was an issue due to transmission fluid leaking from the vehicle. This was completed under warranty. It has been exactly 2 years since the full transmission replacement, and the dealer has just informed us the transmission is failing again and will require another FULL REPLACEMENT. Apparently there is a known issue with the transfer case spline…”

“My 2022 Acura MDX lost motive power due to a transmission and transfer case failure at 64,306 miles. The transmission first became jumpy shifting from 1st to 2nd gear, then began whining and self-correcting. The jerking worsened in stop-and-go traffic until the vehicle became stuck in low gear and at times lost all gears completely. On the drive to the dealer, it nearly would not go into gear at all, and I did not think it was going to make it. The dealer (Crown Acura, [XXX], repair order #XXX)…”

“My 2022 Acura MDX has transmission issues that started at 99,000 miles. After inspection as to why the drive shaft is spinning freely - they pulled the transfer case off and noticed that the teeth are worn down to almost flat, which is cause ing the transmission not to send power to the real wheels. This is consistent with multiple documented transmission - PTU spline failures on 2022-2023 Acura MDXs (reference NHSTA Investigation DP26-001).”

“My less than 5 year old car had a leak coming from the center front of the car. Acura Service said the transfer case and transmission connection spindles were damaged and transmission seals are leaking. They recommended a replacement of both transmission and transfer case, at a cost of over $13,000, and that is after Acura Customer Service gave me a 10% discount on the repair.”
