Hyundai Motor Co and affiliate Kia Motors Corp said on Wednesday they will recall about 168,000 US vehicles at risk of fuel leaks, after recalling them in 2017 for engine fire risks, and will offer software upgrades for 3.7 million vehicles.
A high-pressure fuel pipe may have been damaged or improperly installed as part of an engine replacement during the prior recall, and that installation could increase the risk of fire, the companies said.
