5. Aerodynamic Panels
Aerodynamic panels, integral components of modern vehicle design including the 2020 Buick Enclave, contribute to fuel efficiency and reduced wind noise by optimizing airflow. However, these panels can also indirectly contribute to undercarriage noises, potentially manifesting as a “sand blowing” sound as discussed on YouTube. The panels, typically constructed from plastic or composite materials, are positioned beneath the vehicle to streamline airflow and minimize turbulence. Their location and design create cavities and surfaces where debris can accumulate. This accumulation, comprised of sand, gravel, and other road particles, can become dislodged during vehicle operation, generating rustling or scraping noises that may be perceived as a “sand blowing” sound. The panels’ proximity to the road surface and their potential for trapping debris makes them a relevant consideration when diagnosing such noises.
The connection between aerodynamic panels and the “sand blowing” noise arises primarily from two mechanisms: debris entrapment and panel vibration. Aerodynamic panels are often not perfectly sealed against the vehicle’s underbody, allowing debris to enter the space between the panel and the chassis. At highway speeds, airflow beneath the vehicle can cause this trapped debris to vibrate or impact against the panel, generating the perceived “sand blowing” sound. Furthermore, the panels themselves, if damaged or improperly secured, can vibrate at certain speeds, producing similar noises. For instance, a loose or cracked panel may resonate in the wind, creating a fluttering or rustling sound that resembles debris moving within the undercarriage. The shared experiences of vehicle owners, documented on platforms like YouTube, underscore the significance of inspecting aerodynamic panels for both debris accumulation and structural integrity when addressing unexplained undercarriage noises.

A detailed examination of the suspension elements is therefore essential when troubleshooting such auditory issues.
-
Worn Bushings and Debris Entrapment
Suspension bushings, typically made of rubber or polyurethane, dampen vibrations and allow controlled movement between suspension components. As bushings wear, they can develop cracks or gaps that permit the ingress of sand, dirt, and other abrasive particles. These particles can then become trapped within the bushing, generating squeaking, creaking, or grinding noises as the suspension articulates. While not precisely a “sand blowing” sound, the high-frequency scraping or rubbing noises produced by contaminated bushings can be misinterpreted as such, particularly when amplified by the vehicle’s underbody. YouTube videos often demonstrate the process of diagnosing worn bushings and the associated noises, highlighting the visual cues of wear and the audible symptoms.
-
Damaged Struts/Shocks and Internal Fluid Leaks
Struts and shocks control the damping of suspension movement, preventing excessive bouncing and maintaining tire contact with the road. When these components are damaged, they can develop internal leaks of hydraulic fluid or experience mechanical failures within the damping mechanism. Internal fluid leaks can generate hissing or gurgling sounds as the fluid is forced through damaged seals or valves. While this sound is distinct from the rustling of sand, the overall noise profile from a failing strut or shock can contribute to a complex array of sounds emanating from the undercarriage, potentially including elements that resemble a “sand blowing” effect. Diagnosing this requires a visual inspection for fluid leaks and a performance test of the strut or shock’s damping capability.
-
Loose or Corroded Hardware and Rattling
The suspension system is secured by numerous bolts, nuts, and other hardware components. Over time, these fasteners can loosen due to vibration, corrosion, or improper installation. Loose hardware can allow suspension components to rattle against each other or the vehicle’s chassis, generating a range of noises that vary depending on the specific location and severity of the looseness. The rattling noise, amplified by the vehicle’s underbody panels and other components, may be perceived as a “sand blowing” sound, especially at lower speeds or on rough road surfaces. Thoroughly inspecting and tightening all suspension hardware is a fundamental step in noise diagnosis.
-
Spring Issues and Contact Noises
Suspension springs support the vehicle’s weight and provide initial resistance to suspension movement. Broken or compressed springs can cause the vehicle to sit unevenly, affecting handling and potentially causing the spring coils to rub against each other or adjacent components. The resulting metallic scraping or grinding noises can be transmitted through the suspension system and radiate from the undercarriage. While distinct from the rustling sound of sand, these contact noises can contribute to a complex auditory profile that may include elements that are misinterpreted as the “sand blowing” noise. Visual inspection of the springs for damage or misalignment is crucial for diagnosis.
The potential for suspension components to generate or contribute to the “sand blowing noise” underscores the importance of a comprehensive inspection when diagnosing unusual undercarriage sounds. While the primary function of the suspension is ride control, degraded or damaged components can produce a variety of noises that may mimic or contribute to the reported phenomenon.

However, a compromised or improperly installed underbody protection system can inadvertently contribute to noises perceived as “sand blowing,” an issue often discussed and documented on platforms like YouTube. The protective panels, typically constructed from plastic or composite materials, create enclosed spaces and airflow patterns beneath the vehicle. These characteristics can lead to the accumulation of sand, gravel, and other small debris, generating rustling or scraping sounds as the vehicle moves. The effectiveness of underbody protection in preventing damage is contingent on its integrity and secure attachment; a damaged or loose panel can exacerbate noise generation.
The connection between underbody protection and the “sand blowing” noise stems from several factors. First, the panels themselves can act as resonators, amplifying any sounds originating from trapped debris or loose components. Second, if a panel is damaged or detached, it can vibrate against the vehicle’s undercarriage, creating a flapping or rattling noise. Third, the disrupted airflow caused by a compromised panel can lead to increased turbulence and wind noise, potentially mimicking the sound of “sand blowing.” Consider, for example, a 2020 Buick Enclave traversing a gravel road. If the underbody protection panel is slightly detached, gravel can become trapped between the panel and the chassis. The subsequent vibration and scraping of the gravel against the panel, amplified by the panel’s surface area, can produce a noise readily perceived as “sand blowing.”
In conclusion, while underbody protection serves a vital function in safeguarding vehicle components, its condition and installation directly influence the potential for generating undercarriage noises. The “sand blowing” noise, often shared and discussed on YouTube, serves as a symptom of potential issues with the underbody protection system, including debris accumulation, panel damage, or improper attachment. Addressing this issue requires a thorough inspection of the underbody panels, removal of any trapped debris, and secure reattachment or replacement of damaged components.
