GM did not notify me, but my VIN was on the list. You have to call and ask.

And it’s about time they did something. Nothing mentioned about prior years?

Formatting was all goofy on my post there...

Who do you call to see if your truck is on the list? The dealer, or GMC via the 1-800 number in the bulletin? It looks like the 1-800 number, but I'm not completely clear on it.

Thanks!

Another recall I saw had numbers to call...

Cadillac 1-800-333-4223
Chevrolet 1-800-222-1020
GMC 1-800-462-8782
