Dealer not honoring warranty work..2018 5.3 Yukon issues
I have a 2018 Chevy Tahoe with rough idle. Dealer says this one is normal also. Didn't know I had an engine with a racing cam that smooths out above 1500 rpms. This started after vehicle had 12000 miles. Seems to be a common problem. Definetly get Regional GM rep. involved or have GM buy it...- Lazy J
