5 With Excessive Wind and Road Noise
1. Toyota RAV4 Non-Hybrid: Practical but Noisy
The 2026 Toyota RAV4 Non-Hybrid remains a popular midsize SUV thanks to its reliability, utility, and fuel efficiency, but it is often criticized for its cabin noise and coarse engine characteristics. At highway speeds of 70 mph, noise levels can reach 71 dB, according to Oreate AI, which is significantly louder than most competitors.
Drivers frequently report engine groaning during acceleration, noticeable wind turbulence around the boxy mirrors, and intrusive road noise from the wheel wells. Hybrid and Prime models are somewhat quieter due to different powertrain tuning, but the base gas models remain among the loudest in the segment.
The RAV4’s cabin noise results from several design and engineering choices. Toyota prioritizes fuel efficiency and weight reduction over sound insulation. This means fewer heavy sound-deadening materials in the doors, roof, and floorboards, which allows external noise to enter the cabin more easily.
The SUV’s boxy, rugged shape creates aerodynamic turbulence at highway speeds. Airflow around the A-pillars, side mirrors, and thin door seals produces a wind whistle that can make occupants feel like a window is not fully closed.
The 2.5-liter Dynamic Force engine with an 8-speed automatic transmission contributes to the coarse noise. Unlike the hybrid models, the gas engine must work harder and rev higher to reach cruising speed. The transmission’s shift logic can keep the engine in higher RPM bands, increasing mechanical vibration and drone.
Noise from the road is also transmitted through the wheel wells, which have minimal insulation. The stock low-rolling-resistance tires are harder than comfort-oriented tires, producing additional noise, especially on concrete. The roof rails can trap air, creating a high-frequency thrumming sound at highway speeds.
Owners who want to improve cabin quietness often use acoustic mats in doors and trunks, quieter touring tires, and additional door seal gaskets.
The non-hybrid Toyota RAV4 delivers practicality, utility, and strong reliability. However, its cabin refinement and noise control are below the level of rivals such as the Honda CR-V or Mazda CX-5. Buyers who prioritize a quiet and comfortable ride may prefer hybrid versions or competitors with better sound insulation.
2. Honda CR-V TrailSport: Rugged Capability with Added Cabin Noise
The Honda CR-V TrailSport builds on the strong reputation of the CR-V lineup for practicality and comfort, but its off-road-oriented design introduces noticeable increases in cabin noise compared with more urban-focused trims.
While the standard CR-V models are generally praised for refinement and quietness, the TrailSport prioritizes rugged capability. This shift in focus results in a driving experience that can feel busier and louder, especially on highways or smooth pavement.
One of the main contributors to the increased noise is the use of all-terrain tires, specifically the Continental CrossContact ATR. These tires feature aggressive tread patterns designed to improve grip on dirt, gravel, and light off-road terrain.
However, the knobby tread blocks that enhance traction also generate a consistent humming or droning sound when driving at highway speeds, typically above 70 mph. Although Honda incorporates some noise-reducing technology within the tires, the physical characteristics of all-terrain rubber inevitably produce more road vibration and sound than the quieter all-season tires used on other CR-V trims.
Aerodynamic factors also contribute to the louder cabin environment. The TrailSport includes standard roof rails, which disrupt the smooth flow of air over the vehicle’s roof.
At higher speeds, this airflow turbulence can create a noticeable rushing or whistling sound. Additionally, the CR-V’s relatively large side mirrors, designed to improve visibility during trail driving, can catch the wind and produce additional turbulence near the front windows.
Another factor affecting cabin quietness is the difference in insulation and premium materials compared with higher trims, such as the Sport Touring. That top trim features acoustic laminated front side glass and extra sound-deadening materials around the engine bay and wheel wells. The TrailSport generally uses standard glass and slightly less insulation, allowing more road, wind, and engine sounds to reach the interior.
Despite these drawbacks, the TrailSport still provides the spacious interior, comfort, and practicality expected from a CR-V. In comparison with some competitors, it can remain quieter than vehicles like the Toyota RAV4, though it may not match the insulation found in models such as the Subaru Forester Wilderness or Mazda CX-50. The TrailSport illustrates a common trade-off in SUVs, where increased off-road capability often comes at the expense of acoustic comfort.
3. Kia EV9 GT-Line: Quiet Electric Power with Noticeable Wind Noise
The Kia EV9 GT-Line represents Kia’s flagship electric SUV, combining futuristic design, advanced technology, and three-row practicality. As an electric vehicle, it benefits from the inherent quietness of an electric powertrain because there is no internal combustion engine producing mechanical noise.
However, some owners and reviewers have reported noticeable wind and road noise at highway speeds. These sounds are not unusually loud for an SUV, but they become more noticeable because there is no engine noise to mask them, which can create the impression that the cabin is less quiet than expected for a modern EV.
One major factor behind the perceived noise is the EV9’s boxy exterior design. The vehicle’s upright shape and large dimensions resemble rugged SUVs such as the Land Rover Defender. While visually distinctive, this design is less aerodynamic than sleeker electric crossovers.
At highway speeds, airflow around the A-pillars and large side mirrors can create turbulence that produces a rushing or whistling sound near the front of the cabin. Roof rails can also disturb airflow, adding to wind noise when driving at higher speeds or in strong crosswinds.
The GT-Line trim introduces additional features that can contribute to road noise. This version comes with large 21-inch alloy wheels and low-profile tires, which provide a sportier look and improved handling.
However, these tires have less sidewall cushioning than smaller tires, meaning they absorb fewer road imperfections. As a result, vibrations and tire roar from rough pavement can travel more easily into the cabin, especially on coarse asphalt or concrete highways.
Some owner reports have also pointed to quality control issues that can increase wind noise. For example, certain drivers have experienced wind buffeting from the panoramic sunroof seals, particularly during crosswinds. In a few cases, misaligned doors or windows have created small gaps in the seals, allowing wind to whistle at high speeds. These problems are often resolved through dealer inspections or warranty repairs.
Despite these concerns, the EV9 remains quieter than many gasoline SUVs and typically measures around 63 to 65 dBA at highway speeds. While this level of noise is respectable for a large family SUV, it falls short of the extremely quiet cabins found in premium electric competitors.
The EV9 GT-Line still delivers impressive space, technology, and electric performance, though its design and features make aerodynamic noise more noticeable than some buyers might expect.
4. GMC Terrain (Pre-2026): Noticeable Wind and Road Noise
Older versions of the GMC Terrain produced before the 2026 redesign are often criticized for cabin noise, particularly during highway driving. While GMC promoted its QuietTuning technology as a way to reduce noise and vibration, many reviewers and owners reported that the Terrain still struggled with wind, engine, and road noise compared with other compact SUVs.
At speeds above 65 mph, some drivers describe the cabin as having a “wind tunnel” effect, where outside sounds become more noticeable and can make long trips more tiring.
One of the main reasons for this issue lies in the vehicle’s structural and aerodynamic design. Earlier Terrain models used a chassis that was less rigid than newer designs, allowing vibrations from the road surface to travel more easily into the passenger compartment.
Large side mirrors and their mounting points also contributed to turbulence around the doors, sometimes creating a high-pitched whistling sound at highway speeds. In addition, aging door seals and weatherstripping could lose their tight fit over time, allowing wind to leak into the cabin through small gaps around the window frames.
Another contributor to cabin noise is thin window glass and limited sound insulation, especially in the lower door sections. This lack of insulation allows road and tire sounds to enter the cabin more easily.
The rear cargo area is also known for amplifying noise because sound from the rear tires can echo through the open cargo space. On rough pavement or concrete highways, drivers often notice a humming or rhythmic “whop” sound caused by the interaction between the tires and the road surface.
Mechanical factors can also play a role in perceived loudness. Many pre-2026 Terrain models use a 1.5-liter turbocharged engine that can feel strained when accelerating or maintaining highway speeds.
Because the engine sometimes operates at higher RPMs, it can produce a persistent buzzing or droning sound inside the cabin. Some older vehicles also experience issues such as uneven tire wear or failing wheel bearings, both of which can increase road noise.
The 2026 redesign of the GMC Terrain specifically addressed many of these concerns. Improvements included a more aerodynamic shape, stronger body structure, upgraded suspension tuning, and the introduction of more advanced noise-reduction technology. These changes aimed to deliver a quieter and more refined driving experience than earlier versions of the vehicle.
5. Jeep Grand Cherokee: Rugged Design with Noticeable Cabin Noise
The Jeep Grand Cherokee is known for its bold styling, off-road capability, and upscale interior, but its design can also contribute to noticeable wind and road noise during highway driving. The SUV’s iconic boxy shape gives it a distinctive and rugged appearance, yet this same design creates more aerodynamic drag than sleeker crossovers.
As air flows around the upright windshield and large hood, turbulence forms near the A-pillars, producing a rushing or “whooshing” sound that can be heard inside the cabin at higher speeds. Although the interior features premium materials and comfortable seating, some experts note that the vehicle’s sound isolation is not as effective as that found in more aerodynamic luxury rivals such as the Audi Q8 or Lexus RX.
Wind noise is one of the most common complaints associated with the Grand Cherokee. The vehicle’s upright structure naturally increases wind resistance compared with car-based crossovers.
Additional features, such as a roof rack crossbar,s can disrupt airflow over the roof, creating whistling or buffeting sounds when traveling above about 65 mph. Because the SUV rides higher than many crossovers, more of its body is exposed to moving air, which can intensify the turbulence and make the sound more noticeable to occupants.
Road noise is another factor that affects cabin comfort. The Grand Cherokee is engineered with off-road performance in mind, which means it often uses tougher suspension components and optional all-terrain tires.
These elements are beneficial for driving on dirt trails, gravel, or uneven terrain, but they can transmit more vibration and tire noise through the vehicle’s structure. On highways with coarse asphalt or concrete surfaces, the tires may generate a constant humming sound that travels through the floor and wheel wells into the cabin.
Engine noise can also become noticeable under certain conditions. Drivers sometimes report hearing the engine working harder during acceleration or when maintaining highway speeds. In some cases, mechanical issues such as worn tires or failing wheel bearings can create additional humming or droning sounds that increase with speed.
Many owners attempt to reduce cabin noise by adjusting tire pressure, switching to quieter highway-oriented tires, covering roof rack openings, or installing aftermarket sound-deadening materials. These steps can help improve cabin comfort while preserving the Grand Cherokee’s rugged capability and distinctive design.
The difference between a quiet crossover and a noisy one often comes down to engineering priorities. Vehicles such as the Audi Q8 Prestige, BMW iX, Mercedes-Benz GLS 450, Lexus RX 350, and Kia Telluride SX Prestige show how advanced acoustic materials, carefully tuned suspensions, and aerodynamic designs can create impressively calm interiors. These models focus heavily on passenger comfort, making them ideal for long-distance travel and daily commuting.
Other crossovers, including the Toyota RAV4 Non-Hybrid, Honda CR-V TrailSport, Kia EV9 GT-Line, earlier GMC Terrain models, and the Jeep Grand Cherokee, reveal how certain design traits can introduce more noise into the cabin. Boxier shapes, off-road tires, large mirrors, and lighter insulation often allow wind turbulence and road vibration to become more noticeable at highway speeds.
For buyers comparing crossovers, cabin insulation is an important factor that affects comfort every time the vehicle is driven. Choosing a model with strong sound isolation can make daily trips quieter, more relaxing, and far less fatiguing.
