US regulators have opened an investigation into General Motors’ Hummer H2 after three consumers said a wheel came off the large SUV after a steering part cracked, Reuters reports.


The National Highway Traffic Safety Administration (NHTSA) said it has begun a “preliminary evaluation” — a step that often precedes a recall — into the 2003 and 2004 model year Hummer H2.
 
The report said that four consumers complained that the steering knuckle fractured at the lower ball joint attachment, causing them to lose control of the H2, including three who said a wheel separated from the SUV, NHTSA said.


One consumer crashed into a parked vehicle, and a second veered into oncoming traffic before running into a ditch on the opposite side of the road, NHTSA said.
