NHTSA Opens Probe Into 1.2 Million Teslas Over Front Suspension Failures

The National Highway Traffic Safety Administration has opened a preliminary investigation into roughly 1.2 million Tesla vehicles over reports that a front suspension component can fail while driving, according to a filing from the agency's Office of Defects Investigation.

The probe covers 2018-2020 Model 3 sedans and 2021-2023 Model Y SUVs. NHTSA says it has logged 156 complaints describing the detachment of the front lower lateral link, a part that connects the wheel assembly to the vehicle's frame and helps keep the suspension stable.

According to the filing, most drivers who reported the problem said it happened with no advance warning. Some described hearing unusual noises beforehand. NHTSA's language is blunt about the stakes: a detached lateral link "could result in a loss of vehicle directional control," which is regulatory-speak for a driver potentially losing the ability to steer properly.

NHTSA says it has not recorded any crashes, injuries, or fatalities tied to this specific complaint pattern. This is a preliminary evaluation, the first of several steps NHTSA can take before ordering anything. The agency reviews complaint data, may request records from Tesla, and can escalate to an engineering analysis if the evidence warrants it. A recall is not automatic and has not been ordered.

Tesla's suspension history

This isn't Tesla's first suspension headache. In 2021, the company recalled 2,791 Model Y and Model 3 vehicles over a separate suspension defect. It followed that with another recall covering Model 3 vehicles after NHTSA investigators found a loose fastener could let the lateral link separate from the sub-frame.

NHTSA's new filing explicitly states that the complaints driving this current investigation do not appear related to those earlier issues. This looks like a distinct problem, not a recurrence of something already fixed.

What the complaint data shows

The 156 complaints span roughly five model years and two of Tesla's highest-volume vehicles, out of a combined population of about 1.2 million cars. That's a small fraction of the fleet reporting the issue, and zero confirmed crashes or injuries attached to it. This is a pattern regulators think deserves scrutiny, not a documented safety crisis yet.

At the same time, a part disconnecting from the front suspension with no warning is not a minor inconvenience if it happens at speed. NHTSA's own description of the risk, loss of directional control, is serious enough that a formal probe is a reasonable and unremarkable regulatory response. Preliminary investigations exist precisely to sort out whether isolated complaints reflect a real defect trend or just noise in the data.

Tesla has not issued a public statement responding to the investigation, and the company has not confirmed or disputed NHTSA's characterization of the complaints in the filing. Tesla did not immediately respond to the underlying Reuters report that first surfaced the probe.

What happens next

NHTSA's preliminary evaluation will determine whether the agency has enough evidence to move to a full engineering analysis, the stage that typically precedes a recall decision. There is no timeline in the filing for when that determination will be made public.

Until then, the practical status is straightforward: no recall, no confirmed injuries, but 1.2 million vehicles now under federal review over a part failure that, per NHTSA's own complaint data, has sometimes come without warning.
