The Fit generally does not feel unstable at 120 km/h on the highway. As long as there are no technical issues with the car, there is no car that truly feels "unstable." If it does feel unstable, it might be due to insufficient familiarity with handling the car. Here are the detailed explanations: 1. The meaning of "unstable": One scenario is severe body roll when changing lanes, and the other is significant vertical movement when going over bumps. These situations are not considered "unstable" because they are simply the suspension system's response to external forces. Each car's suspension characteristics are different, leading to varying reactions. If you are familiar enough with a car, you will adapt to its suspension characteristics, and any movement of the car will be predictable, naturally eliminating the feeling of being "unstable." 2. "Unstable" has little to do with weight: On the contrary, a heavier car transfers more weight during emergency lane changes, increasing the pressure on the suspension and potentially amplifying the suspension's deformation, making the car feel more "unstable."

Driving a Fit at 120km/h on the highway isn't as daunting as it sounds. I own a third-generation Fit with the 1.5L engine. The low chassis and lightweight body do make the steering feel a bit 'floaty' when encountering crosswinds or passing large trucks—it's like an invisible hand gently tugging at the wheel. But honestly, keeping both hands firmly on the steering wheel usually keeps it steady. Last time crossing the Yangtze River Bridge in heavy rain, reducing speed to 100km/h eliminated the floatiness completely. Pro tip: maintain tire pressure at 2.4Bar—underinflated tires exaggerate the vague steering feel. Also, avoid overloading the car for highway trips; that time I packed the trunk full of luggage, the rear end felt like it was 'swaying like water sleeves' during corners.

Last time I took my sister's Fit on the Shanghai-Hangzhou Expressway and specifically tested the 120km/h cruise control. The car feels quite stable on smooth roads, but after encountering road joints with 'thud thud' sounds, the body shows slight lateral wobbling, like walking on springs. The most surprising part was that the body roll during cornering was more restrained than I expected. Although the factory-fitted 185 narrow tires are fuel-efficient, their wet grip is indeed insufficient. I recommend upgrading to a set of Michelin Primacy 4 tires—the improved grip makes the car's dynamics noticeably more planted. Cars with tires older than three years should pay special attention, as aged rubber can even cause skidding over white speed bumps.

The stability of the Fit at 120 km/h largely depends on the condition of the chassis. Having serviced dozens of Fits, I've noticed that cars with rear tire wear tend to feel particularly floaty at high speeds. One owner complained about the floating sensation, and upon inspection, we found a 2 cm crack in the rear suspension bushing, causing slight lateral movement of the rear wheels when going over bumps. It's advisable for owners of older vehicles to regularly check the rubber components of the chassis, especially for cars over 6 years old. The original springs lose their support over time, which can also contribute to the floating feeling—replacing them with KYB Blue dampers can resolve this issue. One detail many overlook: dark tint on the rear windows can disrupt airflow, making the suction effect more noticeable when being overtaken suddenly.
