Did you tried to reset (procedure in owner manual)? Close sliding door and you have to disable the switch for sliding door located at over head console, than remove fuse for radio from under the hood fuse panel for 30 seconds (I believe it 10 AMP Pink - # 29), than you re-insert the fuse and wait 5 seconds than enable the switch over the head console and try to open with either switch (overhead or next to sliding door).
I have same problem many times but I reset it per instruction and it works.
