The Range Rover 2023 Autobiography P530 model has an audible hissing sound when the brakes are used.

Although we much like our recently acquired Range Rover, we find it necessary to address a bothersome auditory disturbance associated with the "start/stop" feature, characterized by a persistent hissing noise of considerable decibel level, which has becoming more irksome. The device in question seems to resemble an electric air diffuser, which operates by allowing air to be released via a tiny aperture. The phenomenon under consideration presents a challenge in terms of articulation, since it involves the occurrence of an audible "click" sound when engaging the brake pedal, even while the vehicle is stationary. Subsequently, a faint hissing sound emerges and persists for around 20 seconds. Subsequently, the motion ceases, resulting in a complete absence of auditory stimuli inside the enclosed space of the cabin. Subsequently, I gently apply pressure on the brake pedal once again (while the vehicle is still and the engine is operational), prompting the emission of a hissing sound that persists for a duration of about 15 to 20 seconds, after which it abruptly ceases.

The automobile in question is a recently manufactured vehicle with zero kilometers on its odometer. The item was acquired 48 hours ago, and it emits a sound that is quite perceptible and bothersome. Given that the product is in its initial stages, it is plausible to assume that this occurrence is typical. However, is there a means to conceal or disguise it? From whence does it originate? The sound seems to originate from a location underneath or behind the steering mechanism.

Attempts have been made to deactivate the temperature control system, air-conditioning, and other operational features, nevertheless the issue persists. The occurrence begins only upon the use of the vehicle's braking system, regardless of whether the vehicle is stationary or in motion, and ceases after about 20 seconds.

There is a possibility that the sound being described is the typical auditory emission produced by the vacuum pump responsible for the brake booster. In such instances, it is noteworthy that the pump tends to generate a discernible level of noise. Is there a method to enhance the level of insulation in this? Is it recommended to proceed in such manner?

I had previously brought my vehicle to the authorized dealership for the same issue and was informed that several complaints had been lodged over the aforementioned sounds. Additionally, the manufacturer was notified for instruction. I also conducted an evaluation of an other L460 model at the dealership, and encountered the same problem. The ultimate conclusion is that this occurrence is within the expected range for this particular model, and it is anticipated that a resolution will be identified in due course.

Regrettably, the noise being emitted is a typical occurrence resulting from the pressured braking system. The persistent annoyance of this particular issue becomes more bothersome with time, since it uniquely affects my emotional state. Regrettably, no other vehicle in existence exhibits this particular behavior. However, the available options for addressing this matter remain limited. The presence of this feature has seemingly been included in all previous models for a number of years.

My device is experiencing the same issue. The situation is causing me significant distress.

Attempts have been made to mitigate the noise by inserting foam material beneath the dashboard, however, these efforts have been ineffective. The presence of a somewhat bothersome high-pitched hissing sound persists, causing considerable distress, but there are few options available for mitigation.

I am also experiencing the same problem. My own experience indicates that the issue I encountered began to manifest itself at about the 5,000 kilometer threshold, a circumstance that I see as peculiar.

Interestingly, my condition deteriorated at that very point. I am curious about the potential discrepancy in wear between the actuator or other components.

It was only after a few months of automobile ownership that I began to perceive an auditory sensation characterized by a continuous, low-pitched noise, sometimes referred to as a "hissing" sound. I possess a heightened sensitivity towards auditory stimuli that deviate from their expected context. Consequently, I am inclined to assert that the aforementioned auditory manifestation was absent throughout the first months subsequent to my acquisition of the automobile. I really dislike the auditory experience. Furthermore, the auditory perception of the braking noise is heightened when my foot is applied to the brake pedal. Notably, adjusting the pressure on the brake pedal, either by increasing or decreasing it slightly, results in alterations to the sound emitted. It is somewhat vexing.

I took my vehicle to the authorized dealership where it was repaired by the service technicians. According to the source, when the ABS is activated, a distinct auditory signal is emitted.
