US ends probe of GM headlamp failures with no added recalls

<p>DETROIT &mdash; U.S. safety regulators have determined that two recalls of older General Motors vehicles for headlight failures were big enough to take care of the problem.</p>
<p>The National Highway Traffic Safety Administration says in documents posted Friday that it’s closing a 4-year-old investigation without seeking any more recalls.</p>
<p>In 2017, the agency opened a probe to see if recalls from 2014 and 2015 covered enough vehicles. The investigation included nearly 318,000 GM full-size SUVs as well as Buick Lacrosse and Pontiac Grand Prix sedans. They are from the 2002-2009 model years.</p>
<p>The recalls were due to the failure of a headlamp control module that resulted in loss of low-beam and daytime running lights. Investigators looked into whether all vehicles equipped with the same module should be recalled.</p>
<p>But the agency says in documents that the recalls and a warranty coverage program took care of any unreasonable safety risk. Plus, the high beam headlamps would still work. </p>
