General Motors is recalling certain 2019-2020 Chevy Blazer, 2018-2019 Cruise, 2018-2020 Equinox, 2018 Malibu and 2018-2020 Traverse vehicles.

General Motors notes that vehicles equipped with gasoline direct injection engines may have slightly longer cold crank times than that of port injection engines. This applies, for example, to 2016-on Camaro and Cadillac CTS/Escalade, 2014-on Corvette/Silverado/Suburban/Tahoe and GMC Yukon/Sierra equipped with 4.3L, 5.3L, 6.2L LV3, L83, L86, LT1/LT4 engines.

This bulletin applies to all 2013-2018 Buick and other GM models. When diagnosing multiple DTCs, one of which includes U****Byte 71, any control module may set a DTC for one of its inputs, and that data is shared across the communication bus for other modules to do their respective functions. 

General Motors is recalling certain 2020 Cadillac CT6 vehicles equipped with dealer-installed accessory 20-inch x 8.50-inch wheels.
