Second NOx sensor failure in 1100 miles

[DubVBenz]

I will be bringing my 24 LZ0 back to the dealer again tomorrow. This will be my second NOx sensor failure. I'm not ready to lemon this thing, but this will be my third visit since purchasing it new 6 weeks ago. What is it about NOx sensors that they're faulty out of the gate? How is it profitable for GM to sell a truck that needs literally thousands of dollars of warranty work in the first 1K miles? Why would a replacement sensor not fail immediately , aren't they the same parts? **** the EPA and **** biden.

I think your dealer needs to do a little more diagnosis. 

 

On LM2 and LZO, NOx sensor failures haven't been a common failure. 

 

Your comment might make you feel better, but NOx sensors were a thing --- long before your president was even the VP. 

 

And of course, EPA was around long before NOx sensors.
