The issue appears to involve the engine and turbocharger system. The vehicle has shown symptoms consistent with a turbo underboost condition, including loss of power and reduced acceleration. A mechanic indicated that the symptoms may be consistent with diagnostic code P0299 (turbo underboost). The vehicle is available for inspection upon request. This issue affects safe operation because the vehicle loses power unexpectedly while driving, which creates a risk when merging into traffic, accelerating, or maintaining speed in normal traffic conditions. The loss of power is inconsistent and can occur without warning, increasing the potential safety concern. The problem has been ongoing. The check engine light is currently on and has remained on. The warning light first appeared around January 2026, and the issue has continued since then. Similar turbocharger-related issues have been reported in prior model years, including 2022 Chevrolet Malibu vehicles, where coverage or corrective actions were provided, raising concern that the same or similar issue may be affecting 2023 models.

At 40,000 miles, check engine light illuminated. Code reader stated P023F fuel pump secondary circuit open. When trying to take 2023 Malibu to dealership for repairs car would not start. Had to have car towed to dealership. Dealership confirmed same fuel pump error code. Confirmed no recall. Car is currently being repaired by dealership at my expense as dealership & GM says fuel pump is not covered by powertrain warranty. Cost is over $1500! Fuel pump should last longer than 40,000 miles! Please research this faulty fuel pump!
