Transmission & drivetrain

[redacted] on [redacted], traveling 70mph on busy highway, blind spot monitoring failed, gear display failed, and check transmission message flashed across display. Had to guide car safety off road and into parking lot. This was first time ever happened. Did not know what was going on or what was happening; safety features like blind spot monitoring (especially after becoming accustomed to) failing all of sudden could have caused a major accident by inadvertently cutting someone off, decrease in speed, etc. Turned vehicle off and all lights disappeared. Had car looked at by Honda Dealership next morning; notified it was a P0741 code and failed torque converter. These systems apparently always go down with this code. Told it was associated with known issue of SB23-029 after they consulted with a local Acura dealership. …

Apr 2025

The vehicle has developed a serious transmission defect involving harsh shifting, delayed engagement, and repeated slipping into neutral while driving. Since picking the vehicle up from Key Acura after an inspection, the condition has worsened significantly. The "Check Engine" light, the flashing "D" indicator, and the transmission warning light are now consistently illuminated. Prior to the dealer visit, these warning lights were intermittent; they are now on at all times. The vehicle can unexpectedly lose propulsion or fail to accelerate, which creates a safety risk during normal driving, especially when merging, crossing intersections, or turning. The symptoms are consistent with the known torque converter and transmission issues documented in Acura Service Bulletin 23 029, which applies to 2017-2018 RDX models. …
