Hi, you have come to the right place.

does the car have the latest ECU and TCM update?

there is a service bulletin (NTB11-089) that says:

2007-2012 NISSAN MAXIMA; LOW POWER 0-40 MPH
Vehicle has low power 0-40 mph, and Power is normal above 40 mph,
and There are no DTCs stored. (meaning check engine light is not on).

ACTION
Before doing any other diagnostics or repair,
Inspect (and if needed) repair the ABS/VDC wheel speed sensors/signals.
• Refer to the Service Manual as needed.
• Perform “line graph” diagnostics on each sensor while driving. Inspect and repair as needed any sensor with a spike in the output signal or that has a different value than the other sensors.
NOTE:
• The most likely cause of the above concern is an issue (sensor, wiring, or debris on sensor/rotor) with the output signal from an ABS/VDC wheel speed sensor.
• A weak or erratic output signal from a wheel speed sensor can cause poor performance or lack of power from a stop, or at low speeds.
• Do not replace the TCM or CVT unit when repair of a signal from a wheel speed sensor will resolve the issue.

(The CVT is the transmission and the TCM is the computer that controls the transmission)

We had another user with a similar probably and he got his fixed.
ended up being an ABS sensor and cleaning the other one.
