So how many of you have had engine lifter problems in Chevy trucks. My went out on my 2017 at 66,000 miles. Not under warranty. Replaced at Chevy dealer. Went out again 6,000 miles later and was under warranty. Has gone out again 6,000 miles later and under warranty from the last repair. I will now put in the module to keep it from shifting into 4 cylinder. But I talk so many people that have this problem with the Chevy engines. No doubt the only way to go is to add the $150 module to keep it from shifting but it is sad that Chevy is making such poor engines now.
