ELECTRICAL SYSTEM

2 complaints

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.

Aug 12, 2024

The primary instrument gauge for the QX80 starts to lose illumination from around the speedometer and tachometer. The vehicle has 55,000 miles and is a 2018 model. This is the SECOND time this has happened, with the instrument gauge being replaced first at approximately 32,000 miles for the same reason. Currently the instrument gauge is continuing to lose lighting - making the speedometer impossible to see at night (SAFETY ISSUE). Infiniti Dealership reports that there is a +/- 2 YEAR waitlist for replacement instrument clusters, and that this is a known problem. The same dealership that replaced it a few years ago. This 2nd instrument cluster started going out in the 20-45 mph segment, then 6500-8000 rpm tach, then 0-20 mph.

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 complaint

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.

AIR BAGS

1 complaint

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" .
