Problem overview

Some Lexus LS400 owners report experiencing difficulties shifting out of park after refueling, which can be attributed to several potential issues. One common problem is brake light switch failure, which can prevent the gear shifter from engaging properly. Additionally, some owners have found that using the shift lock override button, located near the shifter, can temporarily resolve the issue. For those stranded, a manual override can be performed by removing a small cap next to the shifter and using a screwdriver to press into the exposed hole while shifting. Other reported causes include faulty transmission sensors, blown electrical fuses related to the transmission system, and issues with battery connections. If these problems persist, it is recommended that owners consult a qualified mechanic or Lexus dealership for a thorough inspection and diagnosis.
