Hi! I just purchased a 2023 CT5-V Blackwing automatic. The selector will not stay in the reverse position - it pops back into neutral every time I try it. I can go backwards if I physically hold the selector in the reverse position but as soon as I let go, it is back in neutral. I tried holding the side button in until it is in the reverse position and tried releasing the side button just before the selector reaches reverse without success. There has got to be a trick that I don't know about to get into reverse! This is my first experience with an electronic gear selector mechanism. Thanks!
