“Driving our newly purchased 4 week old Suburban down i95. Following a bathroom break at a rest stop, we loaded up in the car, started it via the push ignition and drove down the on ramp onto the highway. Within seconds, smoke began billowing from the hood.

GM's own number for this recall is 18289). At low speeds (typically parking lots, under 5 MPH), when turning, we intermittenly lose power steering. This is more common when switching directions rapidly such as during a parking maneuver. Simultaneously, headlights and interior lights intermittenly dim. The instrument cluster screen will display random warning messages (“roll window down then up”, etc). …”
