The gen-3 patterns, now background noiseminor
- 1.5L turbo I4
The 1.5T's earlier headline issues — the 'engine power reduced' charge-air-cooler condition, the hard-brake-pedal vacuum pump, cooling-system wear — still exist mechanically, but they no longer dominate the 2021 complaint file. GM even ran a small support program (internal 10189210) for 2021 cars built without the charge-air-cooler cold-weather shutters. Treat these as things to check rather than expect: a reduced-power message, a firm brake pedal, or a temperature-gauge climb still points to the known culprits.
