Rogue Hybrid Gear Selection Failure

That sounds unsettling, like a symphony of mechanical woes! The display malfunction and transmission issues point to a potential control unit problem. Have you checked the transmission fluid level and condition? Low or contaminated fluid can mimic these symptoms, though a faulty display suggests an electronic issue. Any recent electrical issues, like a dead battery or jump start? These can scramble the electronic control units.

I verified the transmission fluid level, and it's in the acceptable range and of good quality. The vehicle hasn't had any recent electrical issues. Given that, is the control unit the most probable cause?

Based on your examination and eliminating simpler causes, the symptoms strongly suggest a defective control unit. It's behaving like a conductor who's lost their baton! I'm hesitant to diagnose without a scan, but the display failure and transmission issues are a major indicator. Seek a professional diagnosis from a workshop with Nissan diagnostic tools. They can pinpoint the faulty control unit.

I brought the Rogue to a trusted workshop. The diagnosis confirmed a defective control unit, as you suspected. The repair cost will be approximately 1000€ Thank you again for your assistance!
