The National Highway Traffic Safety Administration has opened a formal investigation into 1.2 million Tesla Model 3 and Model Y vehicles, focusing on reports of suspension failures that may cause drivers to lose control. It’s one of the largest safety probes Tesla has faced in recent years and adds new pressure to a company already under scrutiny for quality and reliability issues.

The investigation centers on complaints that key suspension components — including control arms and steering knuckles — can fracture or detach during normal driving, sometimes without warning. Drivers have reported sudden clunks, wheel misalignment, and in more severe cases, wheels folding inward or outward. NHTSA says the pattern suggests a potential defect rather than isolated wear‑and‑tear.
Tesla has previously argued that many failures stem from driver abuse or damage from potholes, but regulators say the volume and consistency of complaints warrant deeper review. The probe will examine whether Tesla used parts prone to premature failure, whether manufacturing changes contributed to the issue, and whether the company should have issued a recall earlier.
For owners, the concern is straightforward: suspension failures can lead to loss of steering control, especially at higher speeds. That risk is amplified by the sheer number of vehicles involved — Model 3 and Model Y make up the bulk of Tesla’s US fleet.
The investigation also arrives at a sensitive moment for Tesla. The company is navigating slowing sales, rising competition, and increased regulatory attention on both hardware reliability and vehicle safety systems. A large‑scale suspension recall would be costly and could further erode consumer confidence.
NHTSA’s next steps include engineering analysis, part inspections, and a review of Tesla’s internal data. If regulators determine the defect poses a significant safety risk, the probe could escalate into a mandatory recall affecting more than a million vehicles.
For now, the message from regulators is clear: Tesla’s suspension issues are no longer anecdotal — they’re a national safety concern under federal investigation.
