Howdy everyone,
I’m new to this forum so I don’t know if there is a better place for this to be or not.
I have a 2024 gmc sierra that I have a C15C700 code on. The brakes were very spongy when I bought the truck so I bled the brakes and performed an automatic brake bleed, and when it goes through the process it finishes and it still has the code. It limits me to 43mph and sometimes it will be 62mph. What should I try to get this fixed.
