2.7L I4 12227 of 1,288 parts name an engine. The other 955 fit any, so choosing one here only narrows those 227.
What owners report
6 of 12 components, the largest by share, together 69.3% of all mentions. 6,389 reports filed with NHTSA from 1996 to 2025, read through 17 name and year queries against 1 source name. A report can name more than one component, so these 6,389 reports carry 8,041 mentions, 1.26 for each report, and every share below is of those 8,041. 742 more mentions were filed as unknown or other and are excluded from both the rows and the total.

1,288 parts from 35 brands fit this vehicle across 14 categories, and parts listed here fit model years 1999 to 2026. Suspension & Steering is the deepest at 353 parts from 8 brands. 6 of the 6 components above map to a category we stock, and the other 0 map to none.
Where the two lists meet
Each row pairs a reported component with the shelf that answers it, deepest complaint first.
Engine is the largest single complaint on this vehicle at 21.2%, matched by 78 parts from 9 brands.
What the complaints table says
Every complaint row on the Sierra 1500 traces back to a stocked category, led by Engine at 21.2% and Power Train at 14.0%.
Service Brakes and Electrical System follow at 11.9% and 10.6%.
The numbers come from NHTSA's complaint files, the record the government keeps of what drivers report about their vehicles.
A share like Engine's 21.2% reflects how many of the 6,389 filed reports mentioned it - not a chance that your Sierra will have the same problem.
Steering and Structure close out the six, at 6.0% and 5.6%.
