2023 Nissan Versa POWER TRAIN,ENGINE

Car sometimes stall after releasing clutch too soon on first gear and goes into limp mode. Luckily I haven’t gotten hit from behind yet when this has happened but came close multiple times. The limp mode is what scares me that I will get into an accident.

Car is 4 months old 12,000 miles. 3 intermittent episodes upon startup car has only 20% power even with gas pedal to the floor like it’s in limp home mode. All episodes so far on cold start up 60-80 degree weather. No CEL lights, no misfire, no odd smells. YouTube poster has same problem and ran obd scan tool showing crank position sensor malfunction. Others suspect problem is software issue associated with Nissan removing the push button start from Versa S trim level only cars in 2022/2023 model years and possibly in manual transmission cars only. Car is extremely unsafe to drive in this condition and the female owner is reluctant to drive it 50 miles to work and be stranded. Nissan dealer examined the car and found no issues on first attempt. Car going to the repair shop for a second time.
