The notice doesn't give a reason for the action. It is unclear how many cars are subject to the stop-delivery order or whether the automaker plans a recall.
GM spokesman Alan Adler today confirmed that Chevy dealers received a notice related to some Cruze models on Thursday but couldn’t immediately provide details.
Dealers were sent a list of vehicle identification numbers to help them identify the affected cars.
"Instructions for releasing the involved vehicles from this stop delivery will be provided in the near future," the memo says.
One high-volume Chevy dealer in the Midwest said about 10 percent of his Cruze inventory is affected by the stop sale.
GM last month began a recall of 1.37 million U.S. small cars from 2003-07 model years, including the Cruze predecessor Chevy Cobalt, for faulty ignition switches that have been linked to 34 crashes and 12 deaths.
Last week, GM issued three unrelated recalls covering 1.5 million U.S. vehicles after CEO Mary Barra ordered a stepped-up review of internal safety processes in the wake of the ignition-switch crisis. Those models include Chevy Express and GMC Savana vans, the Cadillac XTS sedan, and three large crossovers: Chevy Traverse, GMC Acadia and Buick Enclave.
The Cruze is GM's top-selling U.S. car, with sales of 248,224 units in 2013. The car also comes with a 1.8-liter naturally aspirated engine and a 2-liter turbodiesel.
Models with the 1.4-liter turbo represent about 60 percent of Cruze sales and about one-third of dealers’ inventory, GM spokesman Jim Cain said.
