Federal auto-safety regulators are opening an investigation into nearly one million General Motors pickup trucks and sport-utility vehicles after receiving hundreds of reports of engine failures. The National Highway Traffic Safety Administration said Friday it was launching the probe into vehicles equipped with a particular GM V-8 engine that had already been the subject of an earlier recall. The regulator has received nearly 500 complaints alleging engine failure in vehicles that had already been serviced under recall, including nearly two dozen that required complete engine replacements.
