How wanted to use non GM DEF for the past four years. My 2015 at 98k went to the shop numerous times Finally corrected when the Cat, down pipe, injectors, etc. at the rate one one per week after checking the fuel and DEF was fixed. So I traded it in fear of having to repair it on my nickel next time. Just traveled the country and bought DEF in Utah and Indiana, 21/2 gallons for $23 and change. Using approximately 1 1/4 gal. per thousand it would be nice to use other than GM DEF GM should make all aware of the issues.

What was the solution??? Presently on a road trip. Second day after having driven 700 miles day one the low coolant light came on shortly after starting out. Hit dismiss and watched the gauge for a few hundred miles. Have now gone over 3000 miles in six days. Have not seen the low coolant msg on the DIC again. Should perhaps also mention the outside temperature during the past three days has shown 100 at times each day. Yes I'd be most interested in the solution to the apparent faulty warning. On the up side the 2017 is getting 1.3 miles per gallon more than the 2015 on a very similar trip.
