Hi, just bought a 2007 IS350 and I've run into issues on startup intermittently. Sometimes after driving a bit, if I shut it down then come back, go to press the brake car won't start, get a message saying essentially "you must press the brake pedal to start the car" but even when I leg press it with 200lbs of force it doesn't allow the start. The start button light turns orange, not green. The car will turn on, radio works, but no turnover. It's happened maybe 5 or 6 times over a week. If I give it time and come back after a bit it seems to start no problem. Battery and alternator tested fine at Autozone and the ODB reader is showing no codes. I have replaced the key FOB battery just in case.
Once it also hit me with the VSC and all check engine lights while driving in 95 degree weather with the AC on, and basically shut down once I parked. I think there may be some kind of overheating issue considering once I leave it alone for a while and come back it's been working?
