2,166+ documented cases · NHTSA complaints · Reddit community · Technical service bulletins
This database covers the seven most documented Tesla Model 3 and Model Y suspension noise faults, compiled from 1,046 federal safety complaints filed with the National Highway Traffic Safety Administration (NHTSA) plus Reddit community reports and technical service bulletins. The #1 most reported fault is Front Upper Control Arm Ball Joint failure. All faults include real complaint samples, diagnosis steps, and replacement part references.
前上控制臂球头
The ball joint's factory seal gradually fails under regular road stress, allowing water and road debris to penetrate the joint. Once moisture enters, it displaces the grease and causes accelerated wear between the metal ball and socket, eventually producing a dry metal-on-metal grinding or clunking sound.
前下控制臂衬套
The rubber bushing inside the front lower control arm hardens and cracks over time due to heat cycling and road stress. As the rubber deteriorates, a metal-to-metal gap opens, producing an impact clunk whenever the suspension compresses — most noticeable over speed bumps or rough pavement.
下控制臂衬套或球头间隙增大
As both the lower control arm bushing and ball joint wear simultaneously, the geometric constraints that hold wheel alignment in place begin to fail. The wheel gains micro-movement at its pivot points, causing toe and camber values to drift progressively — typically noticed first as pulling to one side or abnormal inner tire wear.
控制臂衬套疲劳
When control arm bushings lose their original compliance due to rubber fatigue, they can no longer absorb the small, high-frequency vibrations generated by road texture and tire rotation. These micro-vibrations transmit directly from the suspension into the chassis and up through the steering column, producing a vibration felt in the steering wheel — most prominently at speeds above 60 mph.
控制臂几何偏移
When control arm bushings and ball joints wear beyond tolerance, alignment parameters — camber, toe, and caster — drift outside the vehicle manufacturer's specified range. A wheel alignment can temporarily correct the numbers, but without replacing the worn components, the geometry deviates again within weeks, causing uneven and accelerated tire wear on the inner or outer edges.

后悬架连杆衬套磨损
Tesla's rear multi-link suspension uses multiple rubber bushings to connect the suspension links to the subframe and wheel carrier. These bushings crack and harden over time due to combined lateral load, heat cycling, and — in northern states — road salt exposure. As the bushings degrade, the link-to-subframe gap increases, producing a low-frequency thud or knock when the suspension is loaded: most noticeable when crossing speed bumps or during braking.

后稳定杆连杆故障
The rear sway bar link connects the sway bar to the suspension and uses small ball joints at each end. These ball joints wear over time or can fracture outright, particularly on vehicles that have seen track use or frequently carry heavy loads. A worn or broken link produces a sharp metallic knock when the rear suspension loads and unloads — such as during cornering, braking, or crossing a speed bump.
