Electrical system

“Similar to other complaints, the instrument cluster lighting is beginning to go dim or completely out starting at the high end of the RPM gauge and the low end of the speedometer gauge. This is an issue during night time driving.”

Air bags

2 reports1 crash
“My vehicle is one oil change past the bumper to bumper warranty or 4000 miles. Air bag light is on. My regular mechanic took to dealer. Dealer said they see this problem all the time. Told us that in an accident the bags would not deploy and repair is more than $5000! We contacted Nissan north America. Extremely rude employee said too bad as vehicle was out of warranty. Said "maybe" could have done something if we had serviced vehicle at dealer instead of private shop but too bad. Explained that mechanic at dealership said this is a common problem and he was surprised it is not a recall. She told me well it isn't so that is that. She refused to give me to her boss. "We don't do that" .”

Exterior lighting

“The dashboard bulbs went out from 0-40 mph and 6-8 rpms. It seems to be a common issue on Reddit and I have found complaints on the internet.”

Steering

1 report
“The plastic trim on the steering wheel that is colored to match the other plastic trim in the car has cracked at the 2:00 clock position. The cracked plastic sometimes lifts when turning the wheel which I feel may cause an accident. I have not had it inspected by the dealer of manufacturer as I'm aware they won't repair it currently. There were no symptoms before it happened, it was just cracked/separated one day. Nissan/Infiniti should be required to repair this potential safety issue.”

“The contact wife owns a 2018 Infiniti QX80 AWD. The contact stated that the Telematics Control Unit (TCU) of the vehicle operated in 3G however, the AT&T servers were shutting down causing the functionality of the TCU to become inoperable. The vehicle was not taken to a dealer. The manufacturer was informed of the failure and informed the contact that there was no solution to the failure at the moment. The failure mileage was approximately 25,000.”
