Tesla is facing another investigation into its vehicles by the National Highway Traffic Safety Administration (NHTSA), this time related to an issue with its door handles.
In a new Open Investigation named “Electronic door handles become inoperative,” the NHTSA says that it has received nine complaints from owners of the 2021 Tesla Model Y stemming from “an inability to open doors.”
These issues were reported after “parents exited their vehicle after a drive cycle in order to remove a child from the pack seat or placing a child in the back seat before starting a drive cycle.” Parents said they were “unable to reopen a door to regain access to the vehicle.”
Tesla door handles become unlikely hero as they stump road rager
Four of the nine complaints ended with having to break a window to regain access to the cabin.

The NHTSA goes on to explain that, while Teslas do have a manual door release inside the cabin, a child may not be able to access it:
“Although Tesla vehicles have manual door releases inside of the cabin, in these situations, a child may not be able to access or operate the releases even if the vehicle’s driver is aware of them. As a result, in these instances, an occupant who remains inside a vehicle in this condition may be unable to be rapidly retrieved by persons outside of the vehicle.”
It appears that the agency is attributing the issue to a low voltage in the vehicle’s 12V DC battery. This would mean there needs to be some sort of notification to the driver that the battery is running low on power and should be replaced to avoid this issue.
The NHTSA estimates that 174,290 vehicles are potentially impacted by this issue. It plans to assess the scope and severity of the condition, the agency says. The NHTSA also wants to see what approach Tesla uses to supply power to door locks and the reliability of the applicable power supplies.
