They replaced this Def fluid heater 3 times and the check engine light keeps coming on. They replaced the fuse box, wiring harness end a couple sensors. Anyone else having this problem. Brand new 50k truck. I can’t believe it’s in the shop again!

I have a 2019 that has been in the shop 8 times for EGR sensor. It kept triggering the check engine light.
