DETROIT – General Motors Corp. said Friday it is recalling 86,312 2002 Chevrolet TrailBlazer and GMC Envoy sport utility vehicles for a problem that could cause the gear shift lever to move suddenly out of park.

The shift collar on some of the vehicles was not machined according to specifications, GM spokesman Michael Morrissey said.

There have been no accidents, deaths or injuries reported as a result of the problem, he said.

Of the vehicles being recalled, 969 were included in a September recall for a similar problem with the shift collar. In that recall, GM was concerned it could crack, also resulting in an unexpected shift out of park, Morrissey said.
