There are a couple of reasons why the QX60 may make noise when accelerating. Faulty wheel bearings or scalloping in the tires can cause this noise. And finally, the powertrain is redesigned, which should reduce noise. The latest update to the QX60 brings a 12% reduction in noise.
12% reduction in noise
If your Infiniti QX60 is making a humming noise when accelerating, there is a good chance that your turbo is at the end of its life. A failing turbo will clog the engine and create a whistling or blowing noise. To help you diagnose and repair the problem, you should first examine the condition of the engine’s air filter and the engine itself.
The Infiniti QX60 is a midsize crossover that was completely redesigned last year, with a vastly improved cabin environment. It features a 12.3-inch infotainment screen, a digital instrument panel, and a refined interior. Even the base model is equipped with a panoramic sunroof and heated seats.
The Infiniti QX60 also includes a wireless smartphone charging pad. This feature is standard on the Sensory and Autograph trim levels, and is optional on the Luxe trim. It also has a 17-speaker Bose premium audio system and an in-car Wi-Fi hotspot. Infiniti has spent a lot of time and effort to make its cars as quiet as possible. The new QX60 also includes ProPilot Assist and Navigation Link features, which combine adaptive cruise control with lane-keeping assistance. It also uses cartographic information to slow down for exit ramps.
Tire cupping or scalloping causes whirring sound
Infiniti QX60 owners may notice a whistling or humming noise while accelerating, which is most often caused by uneven tire tread. This problem is also called tire cupping or scalloping, and is often mistaken for a bad wheel bearing. Regardless of the cause, you should have your vehicle checked by a professional.
Another cause of this loud noise is the alternator belt, which can be a symptom of a faulty alternator. Though the alternator belt is less important than the timing belt, it is still vital to the operation of your Infiniti QX60. If the belt is worn or damaged, it could cause vibrations in your engine and could lead to a severe engine problem.
If your car is making a whirring sound while accelerating, you should take it to a mechanic immediately. The issue can be caused by an uneven number of factors, including an oil filter clogged with debris, unbalanced wheels, and worn suspension parts. In some cases, cheap brand tires can be more likely to develop this problem due to the inferior quality of their materials. In addition, a poorly balanced wheel could also make a tire more susceptible to cupping.
Faulty wheel bearing
If you’re experiencing wheel vibrations, it’s likely that you have a faulty wheel bearing. These components play a crucial role in the stability of your vehicle’s steering system, braking distance, and handling. When they become defective, this system will not work properly and could result in dangerous outcomes.
The first thing you should do is contact your infiniti dealership. This company can diagnose your problem and fix it for you. If they can’t fix it, they will replace it. They have a national service number you can call for help.
When a wheel bearing begins to fail, you’ll experience excessive brake pulsation. Moreover, a faulty wheel bearing could cause excessive runout and cause your car to pull to one side. You should replace the wheel bearing as soon as possible. However, you should not delay the process until you are certain it’s a faulty wheel bearing.
A faulty wheel bearing usually fails gradually. It may start making noise a long time before it fails catastrophically. The noise may be constant, or it may come suddenly. If the noise persists, don’t drive the car because it could cause loss of control.
Redesigned powertrain
The new Infiniti QX60 will come with a new powertrain that will help it be quieter when accelerating and braking. The new 3.5-liter V6 engine will deliver 295 horsepower at 6,400 rpm and 270 pound-feet of torque at 4,800 rpm. The powertrain is a much better fit for the car’s size and performance. The noise when accelerating will be reduced and it will feel more natural to drive.
The powertrain has been redesigned by Infiniti in collaboration with renowned driveline supplier ZF. The new transmission has a wider gear ratio spread than previous models and is expected to deliver better driving dynamics, luxurious characteristics on the road, and excellent fuel economy. The company also claims that the shifts between gears are “imperceptible.” The drivetrain also features an Active Torque Mount system that eliminates engine vibrations outside the cabin.
The new Infiniti QX60’s steering wheel is firm and has nice weight. The ride is firm and the steering is responsive, but the car is lacking a sense of connection and communication with the road. The steering wheel is slightly offset from the centerline, which makes it difficult to read if you’re trying to accelerate.
