Just got back from my 5K service. First the good news. They noticed that the shield under the car was loose and replaced it. They increased the volume on the lock beep. Now the not so good news. They are aware of the ECU problem but claim no fix is available. They are not aware of any TRAC problem. They claimed they cannot change the unlock to a single operation (page 17 of the manual). Is there someone I can call that can confirm whether these issues can be resolved or not? I will try the 800 Lexus number first.
