Fuel gauge reads incorrect when it does come on. Dashboard lights stay off until the tank is on E. Unsafe to drive bc you cannot see your speed. When the dashboard randomly flicks on it will show that it is changing the 2WD to 4WD to 2WD WITHOUT anyone actually moving the switch. I know the dashboard leds are not bad, they come on randomly and they are all present.

What 2008 Infiniti QX56 owners say
Most recent owner complaints, unedited.
There are times when driving under 50 mph brake light comes on and the brakes have goes out which cause me to do an emergency pullover turn off the truck for a few minutes and the brakes reset. This is very concerning for me. This has happened on a few occasions.
The contact owns a 2008 Infiniti QX56. The contact stated while driving at an undisclosed speed, the vehicle suddenly stalled. Additionally, the contact became aware that the vehicle was experiencing inaccurate fuel gauge reading. The contact stated that the fuel gauge indicated that there was fuel in the vehicle while the fuel tank was empty. There was no warning light illuminated. No further information was available. The vehicle was taken back to the residence. The contact related the failure to the federal safety agency Campaign Number: 10V074000 (Fuel System, Other) however, the VIN was not included. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not notified of the failure. The failure mileage was approximately 130,000.Â
There was previous recall on this vehicle, 10V‑074 (Infiniti #R1011) for a fuel sender problem, causing the fuel gauge to be inaccurate. Infiniti says it was fixed in 2010. Unfortunately, I am having the exact same problem now, and have run out of gas twice because of it. Infiniti said they can't help because it was already fixed. Safety issue because running out of fuel while driving is dangerous. Both times has been on an interstate. It was a previously reported recall and "fixed" but has failed again. Infiniti says they won't fix it again.
I was involved in an auto rollover accident on January2, 2023 when a driver "t-boned" me in my 2008 Infiniti Qx56 striking the middle of the passenger side of my Qx56 after running a stop sign and failing to yield to my right of way causing my Qx56 to roll over 3 times. My driver's steering wheel airbag did NOT deploy. To my knowledge all the other airbags did deploy. I suffered neck, right shoulder, and lower back injuries from the rollover but remained in the driver's seat as the seatbelt system worked well. My Qx56 was a total loss.
Occasionally Brake light turns on in my dashboard then my braking system loses hydraulic pressure and I have troubling braking till I turn car off then resets and goes back to normal but while brake light us on is very troubling and concerning? This has happened on many occasions since purchasing the car if I remember in 2018
Tl* the contact owns a 2008 infiniti qx56. The contact stated that the fuel gauge was inoperable. The contact stated that the fuel gauge reflected an incorrect amount of fuel in the vehicle. The contact stated that on several occasions the fuel gauge indicated that the fuel gauge showed adequate fuel in the vehicle however, the vehicle stalled and ran out of fuel. The contact stated that the failure was a common failure in similar vehicles. Neither the dealer nor the manufacturer were notified of the failure. The approximate failure mileage was 65,000.
Constant moisture build up causing headlight burnout a dangerous situation didn't know until police pulled me over. Five times this incident has happened. Very expensive fix and extremely expensive replacement. Unfair to consumer auto shops says the company knows about it. A safety recall is needed.
I hear I ping sound like a spring, the break light comes on and I am unable to stop the vehicle as normal. Appears the vehicle is attempting to slow down but does not come to stop as it normally should. Once I turn the vehicle off then back on it's just fine until it randomly occurs again when applying the breaks and/or when the vehicle is idle and the break light comes on. This issue only resolved itself when the vehicle is turned off then back on. It is extremely alarming and could cause an accident.
The brakes on my vehicle has a strange reaction when I brake at times and is hesitant to stop. It doesn't happen often but it's scary. Usually after I stop the vehicle, cut it off & crank it again the problem goes away only to do it again on a later date. After going online I find that many others have experienced the same problem with infiniti qx56 & nissan armada's. I'm sure whether or not it's a ABS sensor malfunction or what but thankfully it haven't happened while being in heavy traffic because I fear I'll rear end another motorist.
