The cuts include scaling back production by 50,000 SUVs and 88,000 pickup trucks, The Detroit News reported.

The company will cut back one shift at four different locations, the News reported Tuesday.

A shift would be lost at Flint and Pontiac, Mich.; Oshawa, Ontario; and Janesville, Wis., the report said.

The cut backs start July 14.

Auto analyst Joe Phillippi of AutoTrends Consulting Inc. lamented the decision to scale back on bigger vehicles. "These are the most profitable things they make," he said.

Phillippi told the News the lost of revenue from the switch "is going to hurt for the next three quarters."

In 2007, GM built 2.7 million trucks.
