The National Highway Traffic Safety Administration just opened a preliminary investigation into roughly 1.2 million Tesla vehicles over reports that a key suspension component can detach, potentially leaving drivers without steering control.
The probe, launched on July 31, covers certain 2018–2020 Model 3 sedans and 2021–2023 Model Y SUVs. NHTSA has logged 156 complaints from owners flagging potential detachment of the front lower lateral link, a critical piece of the suspension system that helps keep the front wheels aligned and the vehicle steerable.
What exactly is happening under these Teslas
The front lower lateral link connects the wheel assembly to the vehicle’s frame and plays a direct role in steering geometry. If it detaches, the driver can lose directional control of the vehicle.
No crashes, injuries, or fatalities have been reported in connection with the issue so far. That’s the good news. The less-good news is that 156 complaints was enough to trigger a formal regulatory response, which tells you something about the severity NHTSA assigns to steering-related failures.
A familiar pattern for Tesla’s suspension
This isn’t Tesla’s first encounter with lower lateral link problems. The company recalled approximately 2,800 Model 3 vehicles back in 2021 over similar concerns. Then in 2023, another 422 vehicles were recalled for the same type of issue.
NHTSA previously conducted a separate investigation into older Model S and Model X suspension systems, which concluded in 2024. That probe found low failure rates and no major safety concerns. The current investigation appears to be entirely separate, focused on the newer, higher-volume Model 3 and Model Y platforms.
Tesla has not issued any public response regarding the investigation.
What this means for investors and the broader market
A pattern of recurring issues with the same component across multiple model years raises questions about whether the root cause was ever fully addressed, or whether prior recalls were too narrow in scope.
Investors watching Tesla should monitor whether NHTSA upgrades this from a preliminary evaluation to an engineering analysis, the next formal step in the investigation process. That escalation would signal the agency has found enough evidence to warrant deeper scrutiny and would meaningfully increase the probability of a recall order. Given that Tesla has already recalled vehicles twice for this same component in smaller batches, the odds of this investigation simply fading away seem slim.
