Alarm beeping/cluster brake led when turning

Every time i make a left, the BRAKE led in the instrument cluster and alarm beep go off. Ive disabled lda and pcs thinking it was that, but no. If im moving really slow and make left, no alarm/brake. If i turn while giving it gas, a little or a lot, it sets off alarm/brake light. Only the brake led (right under 8k rpm), not the red warning message u get from the pcs telling you to brake. Anyone else have this happen?

 

Read a 1st gen thread that had similar issue. Problem was break fluid was low.

Mine is a 2018 20k. Zero hills but used to pull small boat short distances once a month. so theres that. Fluid is a bit over halfway between min and max. Never added since i got truck. Have members had to top off fluid up to max in theirs?

 

There is a Master cylinder recall out. You may want to go online and see if yours is on it. Leaking is what the recall is for.

 

Did you have the TSS recall preformed?
