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!

After purchasing a brand new chevrolet malibu, about 4 months into droving it; the check engine light illuminated and the next day, an error message of “engine power is reduced” was displaying on the dash. The vehicle was turned over to the dealership and two different sensors were replaced. After a day of having the vehicle back after repairs, the check engine light illuminated again. I returned the vehicle to the dealership and was later told that they were unable to duplicate the scenario and the check engine light did not appear anymore. I picked the vehicle up and after another day of driving, the check engine light illuminated for the third time, again with the same engine power reduced message. Vehicle was slow to accelerate from a stop position. The dealership claims to still be unable to duplicate the scenario with no fix at this point.

Incident

I was driving the car from home to work during morning rush hour in downtown Chicago. I was stopped at a red light and the auto-stop feature engaged as it is intended to do. When the light turned green I put my foot on the gas to go but the car wouldn't move. Cars behind me started honking & going around me. I tried various things but couldn't get the car to move although the ignition light was green. I finally put my emergency flashers on, shifted the car to park, pressed the ignition button to turn the car to off position, then depressed the brake pedal and the ignition button to turn the car on again, then shifted to drive and the car then moved forward as normal. No warning lamps have ever appeared re this. I immediately contacted my dealer to report this problem & soon after took the car there, where they confirmed this malfunction & communicated with GM Tech Line to try to resolve the problem while I sat at dealer all day but at end of day there was no resolution & they had no loaner car to give me & I needed the car so I left with it but thereafter always drove it only w/auto-stop feature turned off as I feared if it happened again I could be rear-ended. Dealer has now had my car for a week trying to ascertain how to fix this but because they say this feature is now not acting up they don't know how to fix it & they say GM Tech Line isn't giving them advice on how to resolve it. I cannot leave my car w/dealer indefinitely so now am forced to drive the car in this condition & need to always try to remember to turn off the auto-stop feature (or risk driving it in unsafe condition), which is not the right solution for a brand new car that had less than 2,000 miles on it when this started. Available for inspection upon request.
