Singapore's Land Transport Authority is investigating Hyundai vehicles following reports of accidents involving sudden acceleration while reversing.

In a statement, the authority said Tuesday that it was looking into cases of "unintended acceleration in reverse gear."

The statement said it was too early to draw any conclusions. It gave no further details, but the local newspaper Straits Times cited recent incidents involving taxis from operator ComfortDelGro, which leases Hyundai Sonata cars, among other models. It is Singapore's largest taxi operator with a fleet of 17,000 cabs.

Hyundai Motor said it is looking into the matter.

South Korean consumers have lodged complaints about accidents that they believed were caused by sudden unintended accelerations. But past government probes have found no evidence that this was linked to faulty vehicles.
