About Infiniti QX80
Infiniti QX80 is a full-size luxury Sport Utility Vehicle (SUV) manufactured by the Japanese automaker Infiniti division of Nissan since 2013. The first Infiniti QX80 was introduced in 2013 for the 2014 model year. Before that, it was called as Infiniti QX56. As the Infiniti's model name rebranding since 2014 model year, many models have been rebadged. Though as a young model, Infiniti QX80 outsold other Infiniti SUVs such as the crossover QX50 and QX70; at the same time, it beat the Japanese full-size body-on-frame rival Lexus LX.
When the Infiniti QX80 was introduced in 2013 for the 2014 model year, it was offered in base Infiniti QX80 and Infiniti QX80 Limited trim levels. Infiniti QX80 is the rebadged version Infiniti QX56, so it shares a lot of design ideas with Infiniti QX56. But when Infiniti QX80 comes to market in United States, it has a revised appearance with new front and rear fascias, restyled headlights and other new equipment. However, Infiniti QX80 is still powered by a 5.6 L 32-valve VVEL (VK56VD) V8 engine that could produce 400 horsepower and 413 pound-feet of torque, and this engine is fitted along with a 7-speed automatic transmission.
Infiniti QX80 Common Problems & Maintenance Tips
As a SUV, Infiniti QX80 has a lot more to endure than any other ordinary vehicles. That is to say, it is more likely to have problems. In order to sustain your Infiniti QX80 for a longer time, you have to learn about the symptoms of these common problems in advance:
First, engine overheating. Many Infiniti QX80 owners have complained about this problem and overheating is a serious problem that would impair engine performance and shorten engine lifespan. They also told that they could find leaking coolants on the ground and the vehicle would also be constantly overheating. At the same time, the coolant was in a rusty or oil color and the Low Coolant Light came on. Based on their descriptions, we can assume that the cooling system must have something wrong. You can have an inspection on the QX80 radiator, QX80 fan blade and QX80 fan shroud first. If the engine performance also gets reduced or Check Engine Light is activated, then check if QX80 air filter is clogged.
Second, suspension and braking failures. Suspension system is essential for a comfortable and steady driving journey. In Infiniti QX80, suspension failure manifests as clunking noises can be heard when going over a bump or pothole in the road or could hear a rattle when going around corners, particularly at low speeds; too much wheel movement and steering to pull to the left or right when travelling down the road. Similar in your Infiniti QX80 can be solved by replacing the old control arm. As for braking failure, you should pay attention to the QX80 parking assist distance sensor.
As a matter of fact, there are some other auto parts in Infiniti QX80 also should get your enough attention. Fog light is responsible for providing better driving visibility under adverse weather conditions such as heavy rain or dense fog. So for your driving safety, if you find your QX80 fog lights are dim or flickering and they cannot turn on, then you should get them replaced. Hood latch in Infiniti QX80 is also very important especially for those who have a fan on repairing vehicles themselves. If you find the hood slowly or suddenly closes on its own or does not stay up at all, please make sure the hood latch is working properly before any repair or maintenance.
