Federal safety regulators are investigating roughly 1.2 million Tesla vehicles after reports that a front suspension component can unexpectedly fail while driving. The National Highway Traffic Safety Administration (NHTSA) says the part’s failure can cause a driver to lose steering control. The probe focuses on certain Model 3 and Model Y vehicles produced in recent years and follows dozens of owner reports describing abrupt detachment of a suspension link.
Owners of 2018–2020 Model 3 and 2021–2023 Model Y cars should pay particular attention. Most drivers who reported the problem said they received no prior warning. A small number described hearing unusual noises — clicking, clunking, or knocking — coming from the front of the vehicle immediately before the part failed. In many accounts, the steering felt loose or nonresponsive at the moment the link detached, and the vehicle required towing to a service facility.
What NHTSA Found, and What to Watch For
NHTSA opened the investigation after receiving 156 complaints alleging that a component known as the front lower lateral link separated while the vehicle was in motion. That link is part of the front suspension system and helps maintain wheel alignment and steering geometry. When it detaches, drivers can lose the ability to steer the vehicle reliably, creating a significant safety risk. As of the agency’s preliminary findings, NHTSA says it is not aware of crashes, injuries, or fatalities directly attributed to this particular failure, but the potential for harm is clear given the loss of steering control.
This issue is not entirely new to Tesla. The company previously issued recalls related to the same or similar suspension components: a recall affecting roughly 2,800 Model 3 vehicles in 2021 and another recall involving 422 vehicles in 2023. In both of those cases, Tesla attributed the problem to production issues. NHTSA’s current investigation indicates the newly reported cases exceed the scope of those prior recalls and may not stem from the same root cause, prompting a broader review of manufacturing, design, and service records.
At this stage, NHTSA has not ordered a new recall. The agency’s actions are part of the initial phase of its defect investigation process, during which it seeks to determine how widespread the issue is, what conditions lead to failure, and whether a recall or other remedy is warranted. Tesla has not issued a public statement regarding the ongoing probe. Regulators typically request detailed service records, production data, and component testing from the manufacturer as they work to understand the problem and assess risk.
If you own an affected Model 3 or Model Y, be proactive. Pay attention to any new or unusual sounds from the front of the car, such as clunks, knocks, or scraping. Notice if the steering feels loose, wanders, or requires more input than normal to keep the vehicle centered. Any sudden change in steering behavior should prompt immediate action: safely pull over when conditions allow and arrange for the vehicle to be inspected by an authorized Tesla service center or qualified technician. Document any symptoms you observe and, if possible, retain video or audio records that might help technicians diagnose the issue.
Keep an eye on official updates from NHTSA and communications from Tesla, as further testing and investigation could lead to a formal recall or repair campaign. In the meantime, understanding the symptoms and seeking timely inspection can reduce the risk of encountering steering failure while driving. Vehicle owners who experience a detachment event should report it to NHTSA to help regulators gauge the scale of the problem and speed any necessary remedies.
