Why is your Acura RL 3.5 stuck in park?

Your Acura RL 3.5 may be stuck in park due to a malfunctioning brake light switch, which prevents the shift interlock system from releasing the gear lever. Additionally, issues with the transmission, a dead battery, or problems with the shift linkage could also be contributing factors. It's advisable to check the brake lights and fuses first, and if the issue persists, consult a professional mechanic for further diagnosis.
