NHTSA Complaint #11437006 — 2008 LEXUS IS

Electrical Issues started at approximately 30,000 miles. Random times of power windows not rolling down or back up. Random times of Radio controls not working. After recall of airbags was completed, the Navigation system started having Random issues with the touchscreen. Sometimes it would work and sometimes it didn't. Eventually the touchscreen on the Navigation quit working at all. When the door panels were replaced, the windows started working more consistently. The Air Conditioner stopped working one day. The next day after driving it back into the driveway, over the driveway bump, it started working. The entire electrical system seems like there are wires that make a connection, then maybe come loose just barely enough to no longer make a connection. And just a mechanic's hand brushing against something during a normal maintenance check up fixes it temporarily. Or hitting a bump in the road. Every issue is ELECTRICAL related. There are many other IS250 owners with the same issues all over public forums online. Many too that their Navigation no longer worked after few miles on the car. Could these electrical issues cause a fire? How do we know it can't? It's always a worry when I drive my car.
