“front differential leaking oil/transmission fluid. only front wheels are driving car. no warning lights from car. Independent repair shop diagnosed as a failed front differential due to stripped internal splines inside the differential leading to a leak.”
“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 splines on this model year, and the transfer case was not replaced by the dealer when they completed the first full transmission replacement.”
“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) found the transmission fluid level low and the transfer case fluid dark, indicating the two fluids had been mixing. Diagnostic codes present were described by the dealer as transmission failure codes. After removing the transfer case, the dealer found brown sludge and worn connections between the transfer case and transmission, and noted the vehicle was not far from the relatively common failure of the transfer case. Both the transmission and the transfer case were replaced, and the transmission control module was reprogrammed with a new module. The vehicle was in the shop for approximately six weeks. The repair was covered under the certified pre-owned powertrain warranty at no cost to me.”
“Vehicle had oil leak from transmission/transfer case area. Repair shop discovered splines worn where transmission driveshaft and transfer case meet. A common issue apparently. Caused vehicle to only work as a FWD instead of a FWD vehicle. Was advised transmission and transfer case need replaced a cost of 12-13k for a used pair.”
“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.”
