NHTSA complaint #11738928

Owner complaint summary

I am submitting this complaint regarding my 2022 Acura MDX Advance, currently with 71,007 miles. After completing the standard transmission fluid service around the 60,000-mile maintenance interval, I began noticing abnormal drivetrain/transmission behavior that was not present before. At times, the vehicle feels as if the transmission is slipping, hesitating, or failing to transfer power smoothly. Acceleration can feel delayed, uneven, or weaker than normal, and on some occasions the vehicle seems to surge or accelerate slightly in a way that does not feel consistent with normal pedal input. This is a safety concern because the vehicle may not respond predictably when accelerating from a stop, merging, passing, or driving at highway speeds. A delay, slip, surge, or loss of expected acceleration could increase the risk of a crash, especially in traffic. The symptoms appear to involve the transmission, drivetrain, torque converter, transfer case, software calibration, or related components, but I am requesting a proper investigation to determine the actual cause. My concern is that this issue could worsen or affect other 2022 Acura MDX vehicles if it reflects a broader defect. I am requesting that NHTSA document this complaint and review whether 2022 Acura MDX models may have a safety-related issue that can cause slipping, hesitation, surging, delayed acceleration, or loss of expected power after normal maintenance. Acura should evaluate whether owners need inspection, repair, software updates, or other corrective action.
