US safety regulators have launched an investigation into approximately 1.2 million Tesla vehicles following reports of suspension failures that could affect steering control. The inquiry focuses on complaints involving certain 2018–2020 Model 3 and 2021–2023 Model Y vehicles.
The investigation comes after regulators received dozens of complaints from Tesla owners. Although no crashes or injuries have been linked to the reported issue, authorities are examining whether the defect poses a wider safety risk.
Investigation Focuses on Suspension Component
The National Highway Traffic Safety Administration (NHTSA) said its Office of Defects Investigation has opened a preliminary evaluation after receiving 156 complaints.
According to the agency, the complaints allege that the front lower lateral link detached while the vehicles were in use. Regulators warned that such a failure could result in a loss of steering control and leave the vehicle undriveable.
In many cases, owners reported that the suspension failure occurred without any warning. However, some drivers said they heard unusual noises before the component failed.
At this stage, the agency said it is not aware of any crashes, injuries, or fatalities connected to the reported defect.
Preliminary Evaluation Underway
The investigation is currently in its preliminary phase. During this process, regulators will assess the cause, scope, and severity of the reported problem.
If investigators determine that a safety-related defect exists, the evaluation could eventually lead to a vehicle recall.
The review will also determine whether the reported failures involve a broader issue beyond previously identified defects.
Previous Tesla Recalls Examined
Tesla has previously recalled vehicles because of similar suspension-related concerns.
In 2021, the company recalled around 2,800 Model 3 vehicles due to a production-related issue involving the lower lateral link.
Later, in 2023, another recall covered 422 Model 3 vehicles after similar suspension failures were identified.
However, regulators said the complaints received during the latest investigation extend beyond the scope of those earlier recalls. They also indicated that the reported failures do not appear to be linked to the manufacturing issue behind the previous recalls.
Tesla Yet to Respond
Tesla had not issued an immediate public response regarding the latest investigation.
Meanwhile, regulators will continue reviewing owner complaints and technical data to determine whether additional action is necessary.
The investigation remains ongoing, and authorities have emphasized that the current evaluation does not automatically mean a recall will follow. Instead, it is intended to determine whether the reported suspension failures represent a broader vehicle safety concern.
