General Motors Co (GM) is recalling 51,640 Buick Enclave, Chevrolet Traverse and GMC Acadia SUVs of the 2014 model year because faulty software may cause the fuel gauge to read inaccurately, U.S. regulators said on Saturday. “An inaccurate fuel gauge may result in the vehicle unexpectedly running out of fuel and stalling, increasing the risk of a crash,” the National Highway Traffic Safety Administration (NHTSA) said on its website. GM said in a letter to NHTSA the fuel gauge reading could be off by as much as one-quarter of a tank.
