Hi everyone,
I have a 2020 GMC Canyon deisel with about 3200 miles on it. At about 2000 miles I added DEF to go from 60% back to 100%. Now it has been reading in the 70s But will suddenly jump to 95%. And eventually back to the 70s. What is going on?

Mine does similar. 65% for several weeks and then erratic 15%-65%. Almost like the fluid is sloshing in the tank and causing the level unit to bounce b/t 15-65.. I'm using a Banks IDash to monitor
