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.
