NHTSA Complaint #11554756 — 2019 CHEVROLET SUBURBAN

We have suddenly experienced a problem with our 2019 Suburban, seemingly identical to a problem that plagued 2015 GM light trucks and SUVs (NHTSA campaign number: 18V586. 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). The clock time resets as though the battery was disconnected. Our 2019 suburban has only 68,000 miles and has received all scheduled maintenance. The battery was recently replaced in September 2022 (14 months ago). I have inspected the wiring and found nothing lose.
