NHTSA Complaint #11680268 — 2021 NISSAN TITAN

I am filing this complaint due to persistent and repeated failures of the vehicle’s head unit infotainment system and rear backup camera, and mirror controls on my 2021 Nissan Titan. These failures have occurred multiple times despite repairs covered under an extended warranty. The issues severely impair vehicle safety and usability. The infotainment head unit screen is completely black and unresponsive. The rear backup camera fails to activate when the vehicle is shifted into reverse, eliminating a federally mandated safety feature. During the first failure, the mirror adjustment controls stopped functioning simultaneously with the infotainment failure. Steering wheel audio controls do not activate or change the issue. Although my phone shows as connected to CarPlay when plugged into the vehicle, no display or control function during the failure. These failures have recurred three times, the 2nd time immediately after the first repair. Despite replacing the head unit on the 2nd attempt, it is in for a third time. In total, the truck has been out of service for nearly a month due to these electrical issues. The problem points to a systemic electrical or communication fault affecting multiple vehicle systems. The loss of the backup camera constitutes a significant safety hazard. The vehicle is currently unusable in its full potential in this condition. Repairs have been conducted under an extended warranty with Zurich, including previous head unit replacements. The dealer has performed extensive diagnostics. Electrical grounds, wiring harnesses, and control modules are suspected to be involved. Despite these efforts, the issue persists, significantly impacting vehicle safety and operation. The inability to use the backup camera compromises safety while reversing. The loss of infotainment and steering wheel controls reduces driving convenience and distracts from safe operation. Extended repair downtime affects my ability to use the vehicle reliably. Please advise.
