2026 Infiniti QX80 problems

“As captured in images uploaded herein, the subject Infinit QX80's advanced safety system suite malfunctioned completely and without warning at 948 miles. The vehicle dash captures the numerous systems that simultaneously fail including: collision avoidance, steering assistance, lane assistance, blind spot monitoring - and all systems that rely on the advanced camera suite. Importantly, the first failure happened at highway speed without warning and resulted in the steering assist failing on a banked curve and directly placed a family of six within inches of a high-speed collision with an 18-wheeler. This same, intermittent recuring malfunction has happened TEN additonal times including and after SEVEN authorized dealership repair attempts. The dealer has replaced cameras, the entire dash, rebooted the entire software system, and then undertook a "hail mary" to hard reset the car by unhooking the battery and rebooting the vehicles operating system. The vehicle continues to malfunction. The dealership cannot replicate the code because the car does not recognize that there has been an error. The failure to store the failure codes means the dash resets every time…”

“I am still having the same issues as the last time I reported this but new issues have occurred as well. The self driving is still disengaging with little or no warning and pulling the vehicle sharply to the left or right causing safety concerns with almost hitting another car or the center median wall on the highway. The stereo is still going black and turning the screen off. When you attempt to remedy, the buttons and screen are all frozen. When I power it off the AC goes off. The other issue is the crash warning is popping up when I'm trying to take off from a stop light, causing the wipers to start and the AC to turn off. One instant the braking applied like I was about to hit something but no cars were in front of me at the light. The car also turned on like it was in auxiliary mode after I got out and walked around to the passenger door to get my child out. These are causing lots of stress and numerous trips to the dealership to attempt to remedy. My vehicle has been at the dealership since Sept 29, 2026 making this the 3rd time and over a month total of not having access to it.”

“Malfunction: see owners manual with forward collision icon popped up. Only went away when we turned the vehicle off. Tried wiping off sensors to see if it was a sensor issue. Continued to happen. When we arrived back to [XXX] I was driving on XXX. Error message came on with a loud beep, vehicle shut off on me while I was driving (screens went black, a/c cut off, idle message flashed across screen and the vehicle stalled out. Engine came back on by itself. I was driving in my neighborhood leaving my home address. Took it to the Infiniti dealership. They couldn’t replicate it and could see the codes thrown. XXX picking my kids up from school sitting at a stop light and the vehicle beeped again when the light turned green and I started to go, idle message flashed, all screens black, a/c cut off, malfunction message came on, engine turned itself back on when the vehicle turned back on. Was told ADAS was reconfigured + software update and sent off again. XXX in the middle of an intersection loud beep, idle message, all screens black, AC cut off, malfunction message on screen again when the vehicle turned itself on again by itself.”

“The contact owns a 2026 Infiniti QX80. The contact stated that after refueling the vehicle, there was an abnormally strong fuel and rotten egg odor inside the vehicle. The vehicle was taken to the dealer, but no cause for the failure was found. The failure persisted, causing the contact and her husband to become nauseous. The contact stated that they were going to seek medical attention later. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 900.”

“many times when I am using pro pilot assist it does not brake to point when it is inches of crashing into car in front, I manually have to apply brakes. in addition while being in full automatic mode (hands free mode) it turns off lane keeping assist completely where if the driver was not Able to make split second decisions it would collide with vehicle near it. there is no warning for pro pilot assist mode to be driven below or above a certain speed, Infiniti dealer advised it should not be used for bumper to bumper traffic or within city. but when even using it on highway it sticks to one side of lane and still requires hands on all times but Infiniti advertises it to drivers it is a "safe hand free option" with no warnings. just a awful accident awaiting to happen.”
