Aug 28 (Reuters) - The U.S. auto safety regulator said

on Wednesday it has closed two separate probes into Fisker's ( FSRNQ )

Ocean SUVs over an alleged door malfunction and a loss of brake

performance, after the electric-vehicle startup issued recalls

to fix the problems.

The National Highway Traffic Safety Administration had in

April opened a preliminary evaluation into 6,781 Fisker ( FSRNQ ) cars

made in 2023, after complaints that riders were unable to open

the door from either the interior or exterior door handle.

The EV firm, which filed for bankruptcy earlier this year,

had recalled certain Ocean vehicles to fix the door issue in

June.

The recall remedy included an inspection procedure for all

four doors and replacement of the outer door handle if a fault

is found, the agency said in a notice.

The NHTSA had opened a separate probe in January into 7,745

Ocean models over complaints alleging partial loss of

regenerative braking over low traction surfaces, without

alerting the driver.

The agency's Office of Defects Investigation said it was

aware of six minor crashes and one injury due to the brake

failure.

The NHTSA said last week Fisker ( FSRNQ ) was recalling 7,745 vehicles

due to unexpected reduction in regenerative braking, which

captures energy lost when cars slow down and pumps it back into

the battery.

The company was fixing the issue through an over-the-air

software update, which is expected to enhance the vehicle brake

system's ability to adapt to various driving scenarios.

Fisker ( FSRNQ ) had also announced recalls in June for thousands of

cars in North America and Europe due to faulty software and

non-compliance with safety standards.
