<p>DETROIT &mdash; Two key groups that offer automobile safety ratings have yanked their top endorsements of some Tesla vehicles because the company has stopped using radar on its safety systems.</p>
<p>Consumer Reports pulled its “Top Pick” status for Tesla’s Model 3 and Y vehicles built after April 27, while the Insurance Institute for Highway Safety plans to remove the vehicles’ “Top Safety Pick Plus” designation.</p>
<p>The U.S. government’s National Highway Traffic Safety Administration is no longer giving the Models 3 and Y check marks on its website for having forward collision warning, automatic emergency braking, lane departure warning and emergency brake support.</p>
<p>Consumer Reports says that removing radar and relying solely on cameras means the safety features may not be there when needed.</p>
<p>A message was left Thursday seeking comment from Tesla, which has disbanded its media relations department.</p>
