An initial safety review of Tesla's best-selling vehicles is now underway at the National Highway Traffic Safety Administration, which received complaints about suspension parts that could suddenly break. In documents posted on its website Friday, NHTSA wrote that 156 drivers have reported a suspension concern that "potentially causes a loss of vehicle directional control."
Owners who submitted complaints often told NHTSA, "The suspension failed without advance warning." Some also reported hearing "strange noises" before the problem occurred.
The document is dated July 31, 2026, with a 7:46 a.m. EDT timestamp and includes a Tesla Inc. stock quote of $310.93, a change of 0.67 percent. The quote was included in the same NHTSA filing that described the suspension complaints. The vehicles involved are among Tesla's highest-volume models, giving the review a broad potential impact.
Model 3 and Model Y have driven Tesla's growth over the past several years, so a safety review touching 1.2 million of these vehicles puts a meaningful share of the company's U.S. fleet under scrutiny. The agency's findings could lead to a recall, though no such action has been taken and the review is still in its early stages.

NHTSA said its preliminary evaluation remains underway. A request for comment sent to Tesla was not returned before publication.
If the agency later determines that the vehicles contain a safety-related defect, it could seek a recall. The filing does not indicate when NHTSA will complete this review, and the agency has not set a deadline for a decision.
The complaints involve 156 reported incidents, and no injuries or deaths were reported. Tesla had not commented as of Friday, and the review remains open.
A preliminary evaluation is one of NHTSA's first formal steps when reviewing potential safety defects. The agency gathers information from consumers and manufacturers and decides whether a problem warrants further investigation. During this phase, NHTSA has not concluded that the reported suspension issue exists across the affected vehicles.
The complaints describe sudden failures that could affect steering or stability. NHTSA's documents say such a failure "potentially causes a loss of vehicle directional control." That is the core concern driving the review of 1.2 million vehicles.
Model 3 sedans and Model Y SUVs are central to Tesla's sales, which makes the scope of this review especially wide. The agency has not determined that all 1.2 million vehicles in the probe have the issue. A recall remains possible if the investigation reaches that conclusion, but no recall has been issued. Tesla had not commented as of Friday, and NHTSA has not set a deadline for its decision.
The NHTSA filing lists Tesla Inc. at $310.93, up 0.67 percent. That price appears in the filing dated July 31, 2026, with a 7:46 a.m. EDT timestamp.
