2020 GMC AT4 HD Recalls

[cNate]

Just dropped the truck off for its first service at 5k miles and there are two service bulletins. Oddly, neither of them show up in my OnStar monthly report or MyGMC app even though they’re dated as released Feb 2020.

 

I already had a seatbelt issue fixed a few months back as a recall. Here’s the two new ones:

 

1. Service Update Bulletin (N192285430): Engine Control Module Calibration Error

 

2. Service Update Bulletin (N192286190): Fuel Leak Due to Accelerated Corrosion
