NHTSA Complaint #11699049 — 2023 NISSAN TITAN

The transmission has issues when temperatures drop below 5 Fahrenheit. Specifically if the outside temperature drops below 5 the transmission does not engage gears correctly and results in sluggish acceleration, erratic RPMs and poor fuel economy. To be clear this is NOT with cold starting the vehicle. This is documented instances of the vehicle after sufficient driving time to warm up. I have documented multiple instances of the vehicle having the erratic RPMs and sluggish acceleration when the temperature drops to below 5. Each documented instance is after driving for a period of time (I note this to again document the vehicle is warm and not a cold start). During these drives the outside temperature drops and goes below 5 degrees during the drive at which point the vehicle begins having the sluggish acceleration and erratic RPMs. To reiterate and ensure it is clear. The vehicle is warmed up. It is not a cold start concern. I keep reiterating this because each time I raise the concern to Nissan and the dealer they simply say it is cold, this issue occurs after sufficient time for the vehicle to warm up. This is being raised to NHTSA because when it is happening the sluggish acceleration leads to general drivability issues, along with the erratic RPMs result in substantial loss of MPG. When it occurs gas mileage drops to generally about 8mpgs at best far below the rated MPG of the vehicle and normal driving characteristics.
