2021 Chevrolet Silverado 1500 — infotainment became glitchy after an OTA update

Log the conditions before you spend. Get a real battery/charging test on the 2021 Chevrolet Silverado 1500, not just resting voltage, before blaming a module. Don't erase codes until someone who can help has seen them. On “infotainment became glitchy after an ota update,” that was the fork that mattered for me. That's the sequence I'd use. If your situation is the opposite, ignore me. Wrote this up on my lunch break.

OP update: scanned the 2021 Chevrolet Silverado 1500 again and still only have the one pending code, no new lights. Parking it somewhere I can hear it better next time.

Ask what changed right before it started. Loaded-suspension checks on the 2021 Chevrolet Silverado 1500 catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. That's the whole play. Make the next action something you can finish this week. I'm keeping receipts and dates in one folder.

I wouldn't throw parts yet. Get a real battery/charging test on the 2021 Chevrolet Silverado 1500, not just resting voltage, before blaming a module. That's the branch I'd chase this week. Just my two cents from doing this recently. Your commute and mine probably aren't the same, but the test still applies. If it repeats twice more I'll book time.
