New York - Tesla said on Friday it was recalling all 90 000 of its Model S luxury electric cars sold worldwide since 2012 after discovering a security problem with seatbelts.
The front seatbelts failed to correctly fasten, but no accidents or injuries had been reported as a result, Tesla said, in a blow to its stellar reputation.
In an email to customers, Tesla said it was ordering the recall as a "proactive" step after learning of a Model S in Europe with a front seatbelt "that was not properly connected to the outboard lap pretensioner."
"This vehicle was not involved in a crash and there were no injuries. However, in the event of a crash, a seatbelt in this condition would not provide full protection," the email said.
The notice said the company had inspected 3 000 vehicles and found no issues, but "we have decided to conduct a voluntary recall as a proactive and precautionary measure to inspect all front Model S seatbelts and make absolutely sure that they are properly connected."
Tesla's cars have been in high demand, despite a price tag of $70 000 and up, and the vehicles had won much praise - until a recent Consumer Reports review which highlighted problems with the Model S.
Some analysts see Tesla's innovations as driving a new model for the auto sector, and predict it can grow from its small base into a major producer.
Tesla plans to unveil its Model 3 electric car aimed at less affluent buyers in March 2016.
Model 3, whose price is estimated at $35 000 - half the cost of other Tesla's - is seen as key to expansion for the carmaker, which has a loyal following among well-heeled buyers.
