Automatic Transmission Control Module problems of the 2024 Nissan Titan

The contact owns a 2024 Nissan Titan. The contact stated that while attempting to accelerate from a stop, the transmission was slipping, and the vehicle jolted and jerked while shifting between 4th and 5th gears. The contact stated that while attempting to stop the vehicle, there was an abnormal clunking sound coming from the transmission, with the vehicle jolting. There was no warning light illuminated. The vehicle was taken to a local dealer to be diagnosed, and the contact was informed that the tcm needed to be reprogrammed. The contact also stated that water was leaking through the sunroof. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 9,000.

The automatic transmission in my 2024 Nissan Titan pro-4x intermittently malfunctions when slowing to a stop. As the vehicle decelerates to about 1–2 mph, there is a distinct “bump” or “lurch” as if the truck has been lightly rear-ended. The sensation occurs most often at traffic lights or rolling stops. •component/system failed: power train – automatic transmission (9-speed). Vehicle is available for inspection upon request. •safety risk: the unexpected jolt can cause distraction and abrupt braking. It raises concerns about long-term durability and could increase the risk of a rear-end collision in traffic. •reproduced/confirmed: yes. I reported this under warranty to a Nissan dealer. The dealer replaced a transmission bracket, but the issue persists. The downshift/lurch can still be reproduced. •inspected by others: the dealer service department has inspected it. Manufacturer has not provided a lasting fix. •warning lamps/messages: no warning lights or diagnostic messages appear before, during, or after the issue. •first appearance: issue began when I purchased the vehicle (at approx 4700 miles) and continues intermittently (currently 19000 miles). •similar complaints: other 2024 Nissan Titan owners have reported the same problem publicly, describing the downshift bump/lurch at low speed. Earlier Titan model years (2020–2023) had recalls and tsbs for tcm/ecm software updates (e. G. , campaigns r22b1, r22a9; tsbs ntb21-028a, ntb22-085) addressing low-speed hesitation and harsh downshifts. My request: I am requesting NHTSA investigate whether the 2024 Titan shares the same transmission calibration defect as prior years and determine if Nissan must provide updated software or other corrective measures to fix this unsafe low-speed downshift behavior. Thank you.
