What's wrong, in plain English

A software problem in these vehicles can cause the power steering assist to stop working, either when starting the vehicle or while driving. This makes the steering wheel harder to turn, especially at low speeds. GM will fix this with a software update, done either by a dealer or automatically over-the-air, at no cost to owners.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your vehicle is affected. 2. Contact your dealer, or call Chevrolet at 1-800-222-1020, Cadillac at 1-800-458-8006, or GMC at 1-800-462-8782. 3. The software update is free and may be applied automatically over-the-air.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 21V455000.
