Our car doesn't even have 100k miles and lost all power while driving to the speedometer as well as radio, lights, etc. . . We even took it to a mechanic who is also having troubles figuring it out. Paid over $500 to have them change the bcm and ignition switch still having issues to the point it will not start.
