GM has issued a service bulletin about a fix now available for the 2020 through 2024 Chevy Silverado, Chevy Tahoe, and Chevy Suburban vehicles for a DEF sensor.

Bought new in 2016 replaced tires @ oxygen sensor I know the engine problems with these so I change the oil very often @ use full synthetic Still original brakes broke down the day after I bought ...

Other than the typical chevy O2 sensor going out, I have had no problems with this car; only had to do maintenance to keep it running smooth.
