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.

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.

So I found a recall on a twenty twenty two malibu l t one point five liter turbo, which is exactly what I have, and the recall describes my exact issue to the t. It spits out a code for a bad fuel pump. G d I fuel pump, and a couple other codes that are secondary like the camshaft sensor fuel bank 1, solenoids, which both I had replaced this week? The car barely has a 100000 miles, and despite the reduced engine power message coming on, like I said every symptom, my car showing is lining up with the recall yet, GM says my vin isn't one that's covered out of the 22 malibu 1.5 onliters and the fix is 30 recalibration of ecm. This is not a new issue to g. M. The older models had a similar issue and like I said, the specific 22 model that I have has a recall and tons of people have had issues. The car won't go over forty I get maybe seven or eight miles to the gallon, no power hardly, speeds on the freeway immediately dropped to dangerous speeds nearly causing wreck. How can they say the same identical engine and yr,make,model isnt covered while there's lawsuits abs tons of people with same issue. Through two mechanics, i've ruled out the other two code issues by like I said replacing solenoids and camshaft position sensor. Please help i'm still paying a good amount of money on a lien. For this, vehicle can't afford eleven hundred dollars for them to replace a fuel pump that truly isn't bad abs only vehicle with daughter who's in wheelchair needs safe reliable car.

The car had multiple components fail, mostly electrical. But the main malfunction is the “Oil Pump” as stated by the dealership service team. Yes it is currently available for inspection upon request. The oil pump failure is the main concern since it is a key component to the vehicle’s engine and performance, this put my safety at risk since it caused several electrical malfunctions causing the car to decrease its engine power while driving on the highway, not only putting the drivers safety at risk but also those around, potentially causing a collision since engine could experience catastrophic failure due to this issue. The problem has been addressed and confirmed by a dealer and manufacturer, but it has not been solved and it has been well over a month now to which they have found no solution since the part was “discontinued.” There were not symptoms or warning signs before hand, except the car engine revving up at stops prior to the to the failure and check engine light coming on the day it was taken to service at the dealership.
