Today I was driving from my home in Brownsville, TN to Southaven, MS with my family to attend a cheer competition for my two daughters. Driving at around 70mph, the typical instrument cluster/heads up display going dark issue happened, but this time the entire truck violently jerked as if the engine shut off but the drive train, considering everything was still locked into gear, pushed the engine over until the power came back on a split second later. That was the first incident. Three other times after that, the instrument cluster and heads up display went dark and came back on as if power was removed and it rebooted (individual objects on the display coming back on as the data from the CAN bus was received). Anyone else experienced the drive train jerking? Not good...this is a 2019 GMC Denali Ultimate for what it's worth... Z
