Quietness is one of the most overlooked aspects of long-term vehicle ownership. A car that feels refined during a test drive can sound very different after years of daily commuting, highway cruising, and exposure to weather and road wear. That is where design philosophy, material quality, and engineering priorities truly reveal themselves.
Some vehicles are built from the ground up to preserve cabin calm over time, using extensive sound insulation, rigid structures, and components that resist vibration as mileage climbs. Others prioritize affordability, modularity, or rugged capability, which can allow noise, rattles, and wind intrusion to gradually creep in.
This comparison highlights both sides of that reality. The first group showcases five cars that are known to stay quiet and composed well into high mileage, maintaining a sense of refinement long after the new-car smell fades.
The second group examines five vehicles that commonly develop noise issues as they age, often due to cost-saving materials, flexible designs, or demanding use cases. Together, they illustrate how engineering choices shape long-term comfort.

5 That Develop Noise Issues
1. Mitsubishi Mirage: Budget Engineering and Rising Cabin Noise
The Mitsubishi Mirage is engineered with affordability as its top priority, and that cost-focused approach becomes increasingly noticeable as the car ages. Unlike pricier rivals, the Mirage lacks extensive sound-deadening materials such as thick floor felt, firewall insulation, and dense door padding.
As a result, engine noise, road vibration, and interior rattles tend to grow more pronounced over time, giving the cabin a loud, tinny character that contrasts sharply with more refined subcompacts.
At the heart of the Mirage’s noise issues is its lightweight three-cylinder engine paired with a CVT. While efficient, this powertrain naturally produces more vibration than larger four-cylinder units.
As engine mounts wear, those vibrations are transmitted directly into the cabin. High-mileage examples may also develop valve train ticking caused by worn lash adjusters or low oil pressure, adding a rhythmic mechanical noise that becomes difficult to ignore.
Several common rattles originate in the engine bay and underbody. A frequently reported issue is a loose intake snorkel or air box, which can buzz against surrounding components. Exhaust heat shields are also known to loosen with age, creating an irritating metallic rattle at idle or low speeds. These problems are inexpensive to fix but highlight the Mirage’s minimal structural buffering.
Inside the cabin, lightweight plastics and simple trim pieces are prone to creaks and buzzes as clips loosen and materials fatigue. Suspension wear compounds the issue. Aging control-arm bushings and sway-bar links often cause clunks over bumps, while worn CV joints can produce clicking sounds during turns. Brake noise is another common complaint, with screeching often caused by debris or basic pad materials.
Some owners also report a humming or whining sound from the CVT as mileage increases, especially if transmission fluid maintenance is delayed. Preventive care can help reduce noise growth.
Regular oil changes, timely replacement of belts and bushings, securing intake components, and servicing the CVT all help keep the Mirage tolerable as it ages. Still, its rising noise levels remain a clear trade-off of its ultra-low-cost design.
2. Jeep Wrangler: Open-Air Freedom at the Cost of Cabin Silence
The Jeep Wrangler is engineered for durability, trail capability, and open-air freedom, but those same qualities make it one of the hardest vehicles to keep quiet as it ages. Its modular design places versatility above refinement, and over time, that trade-off becomes increasingly noticeable in the form of wind noise, rattles, and vibration.
A Wrangler is essentially a collection of removable components. Doors, roof panels, and rear windows are designed to come off, which means they rely heavily on rubber seals rather than permanent body welds.
As the vehicle is driven and flexed on trails, these seals can shift, dry out, or compress unevenly. Even minor changes allow wind to whistle through gaps at highway speeds. The Wrangler’s upright windshield and boxy profile also create substantial wind resistance, amplifying noise once tolerances loosen.
Body construction further contributes to cabin noise. The Wrangler lacks the thick sound-deadening layers found in crossover SUVs, so road texture, drivetrain vibrations, and engine noise transfer more directly into the interior. Off-road use accelerates this process, as chassis flex causes small changes in panel alignment that lead to squeaks and buzzes.
Mechanical wear adds another layer. Aggressive all-terrain or mud-terrain tires are common upgrades, and as they wear unevenly, they produce a persistent hum or roar. The four-wheel-drive system includes multiple shafts, bearings, and U-joints, all of which can generate parasitic noise with age. Inside the cabin, hardtop window seals, seat latches, and trim clips often develop squeaks that require periodic lubrication.
Newer JL-generation Wranglers introduced meaningful noise improvements, including thicker glass, better windshield seals, optional hardtop headliners, and limited use of active noise cancellation. The 4xe plug-in hybrid also allows short stretches of near-silent electric driving. Even so, long-term quietness remains a challenge, and most owners accept noise as part of the Wrangler’s character rather than a flaw.
3. Tesla Model 3 (Early Versions): Quiet Power with Growing Road Noise
Early versions of the Tesla Model 3, produced roughly between 2017 and 2020, are often described as both impressively quiet and occasionally inconsistent as they age. Unlike traditional gasoline vehicles, these cars avoid many of the noise issues that develop over time because they lack internal combustion engines.
With far fewer moving parts, the electric drivetrain eliminates sources of ticking, exhaust rumble, and vibration that commonly appear in high-mileage ICE vehicles. This mechanical simplicity allows the Model 3 to retain a calm baseline driving experience even years into ownership.
However, early Model 3s were frequently criticized for elevated road noise at highway speeds, especially above 60 mph. Because there is no engine sound to mask external noise, wind and tire sounds become more noticeable. To counter this, Tesla employed several acoustic strategies.
Many early cars shipped with tires containing internal foam to dampen road resonance, and the Model 3’s low drag coefficient of 0.23 helps limit wind turbulence around the body. The minimalist interior design also reduces potential squeaks by eliminating complex dashboard assemblies and excessive trim pieces.
Despite these advantages, some owners report squeaks and rattles as suspension components and interior panels settle with age. Door and window seals are a common weak point.
As rubber dries or compresses, wind whistling can develop, especially around the frameless windows and glass roof. Regular conditioning of seals with silicone lubricant helps prevent this issue, and many owners install aftermarket rubber seal kits to further reduce highway road noise.
Suspension-related sounds can also emerge over time. The Model 3’s weight places stress on axle components, and occasional lubrication of axle splines can prevent clicking during acceleration or braking. Some owners add sound-deadening mats in the trunk or under the rear seats to reduce electric motor whine.
Early Model 3s avoid many age-related noise problems thanks to their electric simplicity, but road noise and seal wear remain notable long-term considerations.
4. Fiat 500L: Quiet Intentions Undermined by Aging Components
The Fiat 500L occupies an unusual space in the compact car market. Although it carries Fiat’s small-car image, it was engineered as a compact MPV with long-distance comfort in mind. When new, the 500L benefits from generous sound-deadening and a rigid structure that can deliver a surprisingly calm cabin. However, as mileage accumulates, a number of mechanical and material weaknesses often undermine that refinement.
A key contributor to noise complaints is the drivetrain. Certain engine options, particularly smaller displacement and two-cylinder variants in related Fiat models, are known for producing rattly or coarse sounds that become more noticeable as engine mounts age.
As these mounts soften or crack, engine vibrations transfer more directly into the cabin, creating buzzing or shaking sensations at idle and during acceleration. Even four-cylinder versions can develop intrusive noise if mounts are neglected.
Interior materials are another factor. While the 500L uses thick carpeting and firewall insulation that resist sagging, its interior plastics are lighter and less durable than those found in more expensive rivals.
Over time, repeated heat cycles and body movement can cause trim panels, center consoles, and door cards to squeak or creak, especially on rough roads. The tall body and upright seating position further expose the cabin to flex-related noises as the vehicle ages.
Suspension wear also plays a role. Ball joints, wishbones, and bushings can wear prematurely, producing knocks and clunks that are often mistaken for interior rattles. Wheel bearings are another common culprit, generating a steady droning noise at highway speeds once they begin to fail.
Regular maintenance can help preserve cabin calm. Replacing worn engine mounts, addressing suspension components early, and keeping door seals clean and lubricated can significantly reduce noise intrusion. Still, many owners find that while the Fiat 500L starts life reasonably quiet, age tends to reveal rattles and mechanical sounds that contrast with its original comfort-focused design.
5. Nissan Base Trims: Quiet by Simplicity, Vulnerable to Wear
Base-trim Nissan sedans such as the Versa S, Sentra S, and Altima S approach cabin refinement differently than their higher-spec counterparts. Instead of relying on premium features like acoustic glass or layered luxury materials, these models focus on mechanical simplicity and targeted noise control.
When new, this strategy can deliver a calm driving environment, but as components age, limitations in materials and sealing become more noticeable.
A major advantage of base trims lies in their simplified powertrains. Many use naturally aspirated engines rather than turbocharged units, reducing mechanical stress, vibration, and long-term engine noise.
Nissan’s Xtronic CVT is also tuned to keep engine speeds low during steady cruising, which helps limit drone and harshness across the vehicle’s lifespan. Fewer high-strain components generally mean fewer sources of noise as mileage accumulates.
Nissan has also introduced lightweight acoustic meta-materials in several models. This technology targets common road and engine frequencies using a lattice-style structure rather than heavy rubber insulation. Because it does not trap moisture or degrade as easily, it can remain effective for years, helping base trims stay quieter than expected in early ownership.
Interior design plays a dual role. Base trims typically avoid power seats, sunroofs, and complex trim assemblies, reducing the number of components that can loosen and rattle over time.
Smaller wheels with taller tire sidewalls further help by absorbing road impacts before vibrations reach the cabin. However, cost-driven compromises remain. Without acoustic glass, worn door seals and aging suspension bushings allow more wind and road noise to enter as the car gets older.
Nissan applies consistent NVH engineering across its lineup, including careful sealing of noise paths. Still, as rubber components harden and seals compress, base models tend to lose their initial quietness faster than premium trims. Regular replacement of door seals, bushings, and tires becomes essential to preserving cabin comfort in the long term.
Long-term cabin quietness is rarely accidental. It is the result of deliberate engineering decisions, material choices, and an understanding of how vehicles age in the real world. The cars that remain calm and refined over time tend to share common traits: dense sound-deadening, strong structural rigidity, durable seals, and powertrains designed to minimize vibration. These qualities allow them to absorb years of use without turning noisy or fatiguing.
On the other end of the spectrum, vehicles that develop noise issues are not necessarily poorly designed. Many simply prioritize different goals, such as low purchase price, off-road capability, or modular freedom. In those cases, rising wind noise, rattles, and mechanical sounds are often an accepted compromise rather than a flaw.
For buyers who value long-term comfort, understanding these trade-offs is essential. Noise levels can dramatically shape how a car feels after 100,000 miles, making quiet durability just as important as performance, features, or fuel economy when choosing the right vehicle.
