I think I can deal with this for the mean time but will have to have it check since its still less that 100 thousand miles.
Yes, the button disengages the interlock manually so you have to press it to get in and out of drive.
Take it to a Suzuki workshop to get it fixed. It could be as simple as a broken interlock cable, perhaps a fuse, switch or solenoid but the process to diagnose and potentially fix it is certainly not trivial from what I've read.
