2.0L I4 65.7L V8 664 of 172 parts name an engine. The other 25 fit any, so choosing one here only narrows those 64.
What owners report
6 of 12 components, the largest by share, together 62.4% of all mentions. 2,177 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 2,177 reports carry 3,033 mentions, 1.39 for each report, and every share below is of those 3,033. 115 more mentions were filed as unknown or other and are excluded from both the rows and the total.
What we can sell for it

Where the two lists meet
Each row pairs a reported component with the shelf that answers it, deepest complaint first.
Power Train is the largest single complaint on this vehicle at 15.0%, matched by 8 parts from 3 brands.
Service Brakes are 10.5% of reports and we stock no parts in Brakes for it.
What the complaints table says
Power Train tops the CTS complaint list at 15.0%, ahead of Electrical System at 12.3%.
Air Bags sits close behind at 12.0%, then Service Brakes at 10.5%.
These figures come from NHTSA, the agency that owners contact directly to report a vehicle problem.
Engine and Steering close out the six rows, at 7.4% and 5.2%.
A 15.0% share means Power Train came up most in owner reports, not a prediction for your own CTS.
What the parts table says
Engine Parts is the deepest shelf here, 74 parts across 8 brands, right where Engine complaints point.
Electrical Parts adds 4 parts, and Suspension & Steering another 1, both matching rows on the left.
Exhaust Systems and Off-Road Accessories sit outside anything owners reported, at 50 and 13 parts.
