My latest purchase were a fullest of Coopers for my 2017 2500HD Duramax. Amazing price, like YukonXL04 said they were at least $50 cheaper. Picked them up at the store and then had a tire shop install.
Just bought my truck about a month and a half a go. This warning just came up as well. I'm following to see what all the possible issues are. Is this a common issue? My truck is a 2017 Duramax. Haven't even towed anything yet.
