On April 28, 2026, Reuters reported that the U.S. National Highway Traffic Safety Administration (NHTSA) had closed a probe into approximately 120,000 2023 Tesla Model Y vehicles without requiring a recall. Back in 2023, there were reports of steering wheels detaching due to missing retaining bolts in two vehicles, which initiated an investigation into the matter. Tesla confirmed the cars were delivered without the bolts following end-of-line repairs at its Texas and California plants. The regulator concluded that since both failures occurred within the first 400 miles, if there were any other affected vehicles, they would have surfaced already. Though this is a win for Tesla, Inc.
