NHTSA Investigates Tesla Model 3 and Model Y Suspension Failures
The National Highway Traffic Safety Administration (NHTSA) has launched a preliminary investigation into approximately 1.2 million Tesla vehicles due to multiple complaints from owners about the sudden detachment of the front lower lateral link.
The investigation covers 2018-2020 Model 3 and 2021-2023 Model Y vehicles, with 156 complaints received, most of which occurred without prior warning. Some instances reported unusual noises, potentially leading to loss of vehicle directional control and requiring towing; currently, no related accidents or injuries have been reported.
This incident has prompted an upgrade in Tesla's safety compliance review, with funds and resources potentially directed towards a recall and component replacement. Beneficiaries include regulatory agencies and owner safety demands, while Tesla and the residual value of affected models face pressure.

Tesla has previously implemented two small-scale recalls due to lateral link issues (approximately 2,791 Model 3 vehicles in 2021 and a subsequent 422 vehicles). NHTSA has now explicitly indicated that the new complaints exceed the scope of previous recalls and involve a different production defect.
The investigation focuses on the risk of hardware detachment, and the capital pathway may require Tesla to expand service announcements or initiate a formal recall, motivated by the need to assess the severity and scope of the defect, thereby preventing the risk of loss of directional control from escalating.
Similar suspension component investigations have occurred in other automakers' control arm or link failure cases, and the current electric vehicle industry is in a phase of normalizing safety reviews for high-sales models.
Essentially, this reflects a regulatory shift: from software OTA-led defect handling to formal assessments of hardware physical failures, with the mechanism being that the volume of complaints triggers a preliminary assessment that could escalate to engineering analysis and mandatory recalls.
