NHTSA closes probe into Tesla Model Y steering wheels falling off after finding just two cases

The National Highway Traffic Safety Administration has officially closed its investigation into steering wheel detachments in the Tesla Model Y, more than three years after first raising concerns. Regulators determined the issue was limited to just two early-production vehicles.

Investigation Began After Two Incidents

The probe, known as PE23003, began in March 2023 after reports surfaced of steering wheels detaching while drivers were on the road. Both cases involved newly delivered 2023 Model Y SUVs. At the time, the incidents raised concerns about a potential defect affecting a much larger number of vehicles.

According to the agency’s final report, which is included at the bottom of this article, both cases shared the same root cause. The vehicles left the factory without the retaining bolt that secures the steering wheel to the column. Tesla confirmed the missing part and repaired both vehicles under warranty.

Root Cause Linked to Factory Repairs

Investigators found both vehicles were built during the first week of January 2023 at Giga Texas and Fremont. Each vehicle also went through “end-of-line rectification.,” where the cars are removed from the main assembly line for additional repairs before delivery.

While common across the industry, this step carries added risk, taking place outside standard quality-control checks. In these cases, workers removed and reinstalled the steering wheel but failed to properly secure the retaining bolt, and without those additional quality-control checks, was able to leave the factory.

No Additional Cases Found

Despite the seriousness of the issue, regulators did not find any additional incidents. Both failures happened within the first 400 miles (643 km) of driving, suggesting any similar issue would have appeared quickly in other vehicles.

Since the investigation began, the broader fleet has accumulated significant mileage with no repeat cases. Based on that data, regulators say the likelihood of undiscovered defects is “extremely low.”

Investigation Closed Without Recall

Tesla introduced additional quality controls after identifying the issue. These changes focus on vehicles that undergo end-of-line repairs, helping prevent similar mistakes.

With no further incidents identified, the NHTSA closed the investigation without requiring a recall or additional action. However, the agency noted that closing the case does not rule out a safety-related defect. It can reopen the issue if new evidence emerges.
