My 2022 Chevrolet Malibu LT repeatedly and unpredictably enters a "Reduced Engine Power" state, causing sudden, dangerous drops in speed while driving in traffic. This intermittent loss of power happens constantly on and off, creating an ongoing and severe safety hazard. A diagnostic scan reveals codes P0299 (Turbocharger Underboost), P1101, and P2227. General Motors has an active Special Coverage Program (N252508360) covering this exact turbocharger failure for 2022 Malibus with the 1.5L engine. However, GM and the local dealership refuse to cover the repair, claiming my specific VIN is excluded from their automated list. I have already replaced the MAF and MAP sensors to eliminate electrical faults, had all hoses examined for leaks, and I've replaced the air filter under the hood and in the cabin twice, proving this is a chronic mechanical failure of the turbocharger system. GM is using arbitrary VIN boundaries to avoid repairing a known, widespread manufacturing defect that continually compromises vehicle safety.

Component/System Failure: The turbocharger system failed, specifically the wastegate arm, resulting in loss of boost and reduced engine performance. The failed component should be available for inspection upon request through the servicing dealership. Safety Risk: The failure caused a sudden loss of engine power while driving, placing me and others at risk, especially in traffic situations where acceleration is required (such as merging, crossing intersections, or maintaining speed). This created a hazardous driving condition. Confirmation of Issue: The problem was diagnosed and confirmed by an authorized dealership. The diagnosis stated: “turbocharger wastegate arm damaged causing loss of boost and DTC,” which matches known issues described in GM’s Special Coverage. Inspection History: The vehicle has been inspected by the dealership service department. It has not yet been inspected directly by the manufacturer, police, or insurance representatives. Warning Signs Prior to Failure: Yes. The vehicle displayed a check engine light and reduced engine power message prior to the failure. These symptoms began shortly before the vehicle experienced noticeable loss of acceleration and performance. Additional Information: This failure is consistent with a known issue acknowledged by General Motors under Special Coverage for similar vehicles experiencing turbocharger-related defects. Despite having the same failure and symptoms, my vehicle was excluded based on lot number, not condition or diagnosis.

Purchased the car February 14 2025 with 102,664 miles on it. About 2 weeks ago I was merging on a highway and it went into limp mode and I almost get rear-ended. It felt like it lost all power. The check engine light came on and I drove it to Auto Zone to have it scanned and code P0299 was the code, turbo underboost. I then went to O'Reilly's for a second opinion and their scanner also said turbo underboost. I have replaced all sensors that interact with the turbo thinking maybe it was a sensor but negative. Turbo failure

The vehicle has experienced ongoing engine performance and safety-related warning events. The first major issue was a single occurrence of an overheating condition that displayed an “Engine Overheating – Idle Engine” warning. After that event, the vehicle was taken in for repairs. Following the repair attempt, the vehicle began displaying repeated check-engine warnings and multiple occurrences of “Engine Power Reduced.” During these episodes, the vehicle lost acceleration ability and hesitated. One of the “Engine Power Reduced” incidents occurred while driving at highway speeds with a passenger onboard. The vehicle was unable to maintain speed and required pulling out of active traffic, creating a safety risk. These issues have continued despite previous service attempts and diagnostics. The warning messages and power loss are unpredictable and create a potential hazard, especially during highway driving, merging, or transporting passengers. There has been no crash, fire, or injury, but the repeated sudden loss of power presents a serious safety concern.
