There are 7 owner-reported electrical system complaints for the 2021 Nissan Titanin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.

Vehicle stalled earlier in the day and displayed Service AT. Symptoms included loss of power, fluctuating service lights, but no DTC codes. Shortly after powering off and starting vehicle functioned as intended with slight smoke when activating ac. Vehicle stalled again later within the day, experiencing immediate loss of power with smoke emitting from the engine bay sides. Electrical system began to flash indicating malfunctioning with darker smoke indicating flame intensity. Vehicle was coasted to a safe location away from personal property and other vehicles to ensure safety of surrounding area. Fire Department was contacted as soon as possible after exiting the vehicle and removing as many personal belongings as possible. Truck was engulfed in flames and was unable to be salvaged. Total loss.
My Titan had no real indicators or trouble codes but failed into limp mode and began to smoke and caught on fire! Nissan refused to investigate as they claimed the 2021 was unaffected but shares the same manufacturer plant and engine harness from the 2020.
Twice after a rain I've found substantial amount of water leaking from the driver side, left side dashboard near the ebrake peddle and under steering wheel. The inside padding around the frame is soaked. It appears it could be broken windshield seal or leaking sunroof. I also have video.
The infotainment screen has a very bad glare to it. When backing up and the sun hits it you cant even see the display. While driving and the sun hits the screen the glare is so bad that you cant see anything on the display. My side windows are tinted and that doesn't help. I took it to the dealership and they acknowledged the issue but said there was no resolve for the issue. I have contacted Nissan customer service and they say there is nothing they can do for it. This is a very dangerous problem that can be distracting while you are driving as you will spend too long a time with your eyes off the road to try to see the display. The back up camera is useless when the sun hits the screen which could cause and accident.
Truck shows a message when started and while driving/running. (Key System Error) Also the warning light icon stays lite but sometimes it does go off, other times not
