2023 Nissan Frontier

The 2023 Nissan Frontier was purchased new and is under manufacturer's warranty. Beginning in the summer of 2025, the driver's seatback has unexpectedly moved rearward, including more than one instance where it fell completely back toward the rear seat. Each time, the vehicle has been turned off, the seat is unoccupied, and no one was in contact with the seat controls. The seat does not feel lose when manually pushed and appears normal between incidents. The issue is intermittent and cannot be easily reproduced on demand. This is a serious safety issue. If the seatback recliner mechanism fails while driving, it could suddenly alter the driver's position, reduce control of the vehicle and increase the risk of injury in a crash. I have reported the issue multiple times to an authorized Nissan dealership. The vehicle has been inspected and kept overnight, but the issue was not reproduced and no repair was made. I also contacted Nissan Consumer Affairs who attributed the issue to the seat adjustment switch being accidentally activated. This explanation does not match the conditions under which the problem occurs (vehicle off, seat unoccupied). I am requesting this issue be investigated as a potential defect in the seatback recliner mechanism or power seat system. This condition appears to involve un-commanded seat movement and possible failure of the seatback locking mechanism. I have photos but am waiting for the internet to forward them from my phone to my computer to upload.

The truck jerks while shifting between 0 and 30 mph. This also happens when stopping at stop signs and lights or even just slowing down. I fear that the jerky shifting could cause significant internal damage to the transmission, more specifically teeth breaking off the gears. The power driver seat moves by itself when driving and after it is shut off. I always have to move the seat and adjust when I get in to drive. To test, I have set the seat to the position I use before I get out to see if it adjusts on its own after I shut the truck off. When I get back into the truck the seat is not in the same position.

transmission issues: transmission is jerking, trying to find gears. between 0mph and 30mph. also when stopping at stop sign and lights. truck only has 2,200 miles on it. Very unhappy and feel unsafe driving this truck. Also the power driver seat moves by itself when driving. Always have to move the seat and adjust when driving.
