Hello,
So heres my issue. Every few months my gs-350 (2007) will not start. It will be completely dead.
Replaced the battery and its a month old and fully charged. Both terminals are fully clean. So i jump it and it starts. I bring it to the shop and have them check it, they say that the battery looks fine. They found a wiring issue with the computer and fix it. So today after i pick it up, the car starts fine but (and here is where it gets crazy). The key fob doesnt work. The power locks dont work, telescopic wheel doesnt move, the touch panel for the trunk and gas cap dont respond. Once i start it i can pop the trunk and gas cap. But the steering wheel still doesnt move in or out. So it will start and is drivable but the auxiliary power does not work once the car is off. So there are basic functions that are supposed to work once you turn off the car like the steering wheel, alarm, lights, trunk, gas cap, door locks. Those do not work at all once i turn the car off. Any ideas. Already disconnected the battery for 20 minutes and checked the terminals. Bringing it to the shop on Mon but checking with u guys fisrts.

Anyone have this issue. Thanks

I have a similar issue, I have been trying to figure out. 2007 Lexus GS 450h. It only happens on hot sunny days (I live in Florida). In the morning the car starts right up and runs great. Parked in the sun, many times the key fob will not work. I can see the red light on the fob lighting up, but no reaction from the car. A few minutes later the locks start working but no power will go to the starter button. I open all the doors and try to air out the car. Usually once the interior cools down it will start. Today I could not get it to start in my own driveway this afternoon. I went back this evening once it cooled down and it fired right up. I have tried the break light switch, fresh battery in the car and key fobs, replaced ignition relays . I have looked at replacing the fusible link block. No luck. Somebody has to know what is going on. There has to be a temperature sensor or relay that does not do well in heat. I am feeling your pain.

Please help... anyone...
