2. 2021 Infiniti QX80
The 2021 model reeks of performance and stance. However, many critics rated several vehicles in its category above it because its interiors are a bit outdated and its EPA rating falls below the average.
Other than that, this model is ideal.
The 2021 Infiniti QX80 has a predicted reliability score of 81 out of 100 and RepairPal describes it as Excellent.
One major reason to buy the 2021 Infiniti QX80 includes its powerful engine. The vehicle comes standard with a 5.6L V8 engine that delivers brawny performance with 400 hp and 413 lb-ft of torque.
Its seven-speed transmission equally delivers smooth and swift gear change for a quality ride experience.
The handling of the vehicle is also remarkable as it feels light, responsive, and stable while the sensory trim offers a hydraulic suspension that reduces body roll.
This makes the ride comfortable even on uneven road surfaces. However, road bumps are felt more in models with the available 22-inch wheels than those with the standard 20-inch wheels.
Lastly, its tech features are easy to navigate through. It features a standard Infiniti InTouch™ infotainment system, which includes a dual-display setup with eight-inch and seven-inch touchscreens.
3. 2022 Infiniti QX80
One remarkable thing to look out for in the Infiniti 2022 is its performance.
This Infiniti still maintains the traditional V8 engine that works powerfully. Its engine delivers a remarkable 400 hp, although its acceleration of 60 mph is below the average.
The brakes of this vehicle are outstanding, especially for a full-sized SUV. They’re powerful but easy for daily commutes.
The interior of this model is quite comfortable as the weight, long wheelbase, and tall tire sidewalls lessen the effect of rough surfaces and small bumps.
Its seats are comfortable as they offer support and adjustability while the controls are easy to navigate, but they’re not up to the standard of its many rivals in the same category.
However, many critics would recommend going for other luxurious SUVs in this category because they feel the 2022 QX80 is outdated for its price.

4. 2019 Infiniti QX80
The 2019 model had a lot of complaints in consumer reviews and on the NHTSA website. Some of these complaints include:
For an SUV like the QX80 with adaptive headlights, electrical problems are bad news.
This was one of the most prevalent complaints about the 2019 model and they often connected this electrical problem to the battery of the car. Most owners stated that they experienced battery drain.
The severity of this issue was so bad that the drain came without any warning. It was worse for folks living in colder regions. This malfunction could damage the heating or cooling system of the vehicle.
Forward Collision Warning Problem
There were instances where the 2019 QX80 emergency braking system suddenly engaged the brakes without warning.
However, it was identified that this problem was a general issue with all Nissan models, as there have been pages of reports on Nissan’s AEB system malfunctioning.
Unfortunately, no recalls have been issued on this problem, so owners will have to take the vehicle to a trusted dealership for repairs.
Owners have complained that a rattling sound comes from the vehicle’s engine bay and it can be unsettling. Thankfully, the rattling has been identified to come from a heat shield above the exhaust front tube.
This problem did not require a complex fix, so there was no recall.
Vehicle Speed Control Problems
Owners have complained about the Infiniti dropping gears, especially when the vehicle is traveling up at a highway speed or when it is in cruise control.
Unfortunately, this issue was taken lightly, as many owners stated that their mechanics told them that it is relatively normal. Everyone can agree this isn’t exactly a minor issue and should be regarded more seriously.
5. 2014 Infiniti QX80
The 2014 QX80 is Car Complaint’s worse model year so far. A number of complaints have come from the owners of the 2014 Infiniti model, and some of these issues include:
Unusual Sounds From the Vehicle
Owners have complained that they have often heard a winding noise coming from underneath the vehicle, and it only became more clear when they tried to accelerate.
Most mechanics often associate this problem with a faulty timing belt and a simple replacement will clear the issue. One owner stated that this failure came up around 125,000 miles.
One owner gave his experience and stated that while going at 50 mph, he noticed that the vehicle began to stall. He simply steered off the road but kept driving.
There were no warning lights to indicate a problem. When the car was returned to the dealership, it was diagnosed with a fuel system malfunction.
Fuel Pressure Sensor Leak
This problem called for a recall by the company because it seemed that the fuel pressure sensors may not have been tightened well enough.
Upon usage, this compartment could loosen and cause a fuel leak which we all know can endanger lives and property. This was enough reason for a recall from the company.
Regarding its fuel system, the Infiniti QX80 has a place among cars with the biggest gas tanks.
Frontal Airbag Rupture
This problem was mainly seen on the driver’s side. During airbag deployment in a crash, a sharp component could get in the way and cause the airbags to rupture.
This could increase the risk of metal fragments striking and equally putting the lives of passengers at risk.
Incorrect GAWR Label
Some of the Infiniti vehicles have the wrong Gross Axle Weight Rating. The correct rating was 4,343lb, but some vehicles were listed as 4,497lb.
This incorrect rating could make owners overload their vehicles, which increases their risk of being involved in an accident.
