I have a 2006 GS430 which has an automatic trunk lid closer. Recently my sister slammed the trunk closed not knowing it was suppose to close automatically. Up until that time you just had to make contact between the trunk lid and the car body in order for it to close automatically. Now you have to push the lid until it makes a clicking sound (probably engaging the latch part way) and then it closes the rest of the way using the trunk's motor.
I took it to the local Lexus dealer who at first said the problem was leaking struts (I saw no evidence of this) which they replaced. Before I could pick up the car, they called me and said the trunk motor was making a funny noise (I never heard any kind of abnormal noise) and they were going to replace it also. I got the car back and it is acting the same way it did before it was "fixed".
Does anyone know if there is some kind of sensor that might tell the trunk motor the position of the trunk lid so that the motor knows when to engage? I'm going to take the car back to the dealer, but I'd like to be able to talk intelligently to them about this problem.
Thanks for your help.
