Why does my car jump drive mode on it's own causing car to swerve to left

What is your question?

Car purchase 10/05/21 from Palm Springs Ca dealer. Car had 13429 miles. Action above occurs approximately twice between servicing. We have reported this to the dealer but nothing has been resolved. The dash lights up as it jumps through drive modes once the letters showed BCA. On 5/27/24 I was driving about 40 miles per hour and it jumped into left lane almost causing a crash. It occurs at 40 or 70 miles per hour with no rhyme or reason. No warning at all! This is very scary and dangerous. There are no noises.

What makes this problem better or worse?

Nothing
