DETROIT — General Motors is recalling 45,785 2014-'15 Chevrolet Spark and 2015 Chevrolet Sonic small cars in the U.S. because of a software problem that may affect the safety warnings, the automaker said on Wednesday.
"In certain vehicles with base radios and OnStar, the radio software may cause the radio to lock up in the OnStar Turn-by-Turn Directions mode," GM said in a statement. "If this occurs, the radio display will go blank and all audio functions will cease, including vehicle chimes related to warnings for a key left in ignition and driver safety belt not in use.
"In addition to the vehicle chime malfunction, the radio may not turn off. This could drain the battery and possibly prevent the vehicle from starting."
GM said it is not aware of any crashes, injuries or fatalities linked to the problem.
This is part of a larger global recall of 50,731 vehicles.
No information about the recall has been posted on the Web site of the National Highway Traffic Safety Administration, which oversees vehicle safety in the U.S.
Edmunds says: Owners of these vehicles should wait for their official recall notice and then schedule a service appointment at their dealership. But if you have an immediate concern, it's best to contact your dealer now.
