Last night I was driving from Santa Barbara to Los Angeles, and my IS350 started to beep and the message center said Low Engine Oil Level. My car is due for a service, so the Oil Maint Req'd light was on as well. I pulled off the freeway and the dipstick looks fine to me. I got back on the freeway and every like 20 minutes the car would do this, but then after about an hour it stopped. Anyone know what might be wrong. Could it just be a sensor?

 

What stopped? The car or the flashing maintenance light? If it's the light, it's possible that you have simply reached the oil change interval since it was last reset. If you have your oil changed by someone else, they should have reset your oil change reminder. Honestly, as long as your oil level reads correctly on the dipstick you are okay. If you are due for an oil change, get it done and have them reset the reminder. Sounds like you are okay if that's all it is.
