I have been hearing a random chirping sound under the driver side dash for some time. I have recording the sound and taken it to a Lexus dealer and they don't have a clue regarding cause. It makes the sound with or without the air conditioner working. Sound is a very short chirping or beep type noise. It been occurring for some time and other than the annoyance doesn't seem to have any affect on functionality of any systems. Anyone have any thoughts regarding the cause of this noise?

Whenever I fill my tank with gas it doesn't read full. It only reads about 3/4 tank. It happens everytime I fill my tank with gas.

The antenna worked very well. It got broken in the car wash.

The trunk opens and the windows go down. The top wants to retract, but the latch, or latches wont release. Is this a sensor problem, or is a latch stuck?

There are no more GPS updates for Lexus Gen 2 GPS and I understand the Gen 4 can replace the Gen 2 DVD player in the trunk. Will this replacement work correctly as I can get GPS map updates for the Gen 4 units?

why does sensor lights come on so often. whats wrong with car.

The top opens fine. When you go to close it , the top closes but the trunk lid doesn't come down, hence the back windows don't close and then you can push trunk down. Has a buzzing noise in trunk that seems to be under the trunk covers on the right front. It's not the antenna.

the audio cover does not work

the side mirrors will not go in when ignition is turned off or go out when starting.

reset engine ck light. vsc off came on and would not go off

Dealer states the door was in the open position when I dropped off the car. This is not correct...they just don't want to take responsibility. Dealer wants $225 to fix. Are there instructions available to fix the problem myself?

I had the Lexus mechanics check my horn while they were replacing my (recalled) airbags. They tell me it is a spiral cable problem. Where do I find this part? Or someone to fix it without costing me a fortune?

The original radio was taken out of the car and it was replaced with a after market pioneer Bluetooth radio but now the navigation door and navigation does not work. How do you fix it?

If we don't run the car at least once a week, it dies. Am told it is because the engine computer is always on, draining the battery. This has been happening for years and we have replaced the battery several times. Is there a way to change the software to reduce the drain on the battery? We don't drive it every day and jumping it to drive when we want to is getting old.
