Suspension Parts Snapping Without Warning: 156 Complaints Push NHTSA to Investigate 1.2 Million Teslas

"Without warning" is the most unsettling phrase in this entire investigation. Most owners who reported the issue to the National Highway Traffic Safety Administration (NHTSA) said their vehicle's front suspension gave no warning signs before failing — no strange noises, no vibrations, it just broke. A handful of cases mentioned hearing a sound beforehand, but most drivers described a sudden, unexpected loss of control.

The NHTSA's preliminary investigation covers Model 3 vehicles from 2018 to 2020 and Model Y vehicles from 2021 to 2023, totaling nearly 1.2 million cars. According to documents from the agency's Office of Defects Investigation, the core issue is the "detachment of the front lower lateral link" — a component that, once separated, can cause the vehicle to lose steering control. The NHTSA has logged 156 related complaints so far, with none resulting in a crash, injury, or fatality.

This isn't the first time Tesla's suspension has come under scrutiny. Back in 2021, Tesla recalled 2,791 Model Y and Model 3 vehicles over a similar potential suspension defect. A separate recall of a batch of Model 3 vehicles followed after the NHTSA found that "loose fasteners could cause the lateral link to separate from the subframe." This time, however, the NHTSA has explicitly stated that the current 156 complaints appear to stem from a different issue than the two previous recalls — in other words, this looks like a new, independently emerging failure pattern.

The investigation is still in its preliminary stages, and the NHTSA has not yet determined whether a recall will be required. Tesla has not issued a public response at this time.
