Hello all, I'm new to the forum! My 07 is having some strange issues I can seem to find a way to fully determine the cause of. Intermittently while driving, my TPMS light will start to flash and I get a tpms system fault message, then the doors will lock then unlock and my hazard lights come on. Then after about 30 to 45 seconds the nav will shut off and a vehicle system fault message will come on the radio and that, along with the climate controlled will also shut off. Usually only lasts for about 5 min sometimes longer. It seems to do it significantly more often if I'm using my phone ( internet/calls/Pandora etc). But if I don't use it for any reason the symptom seems to not happen nearly as frequently. Any idea would be greatly appreciated!!
