2022 Chevrolet Malibu

The contact owns a 2022 Chevrolet Malibu. The contact stated that while driving at an undisclosed speed, the message “Engine Power Reduced” was displayed. The failure was a persistent failure. The vehicle was taken to the dealer where it was diagnosed with turbocharger failure. The contact was informed that the turbocharger needed to be replaced. The vehicle was not repaired. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 82,950.

The contact owns a 2022 Chevrolet Malibu. The contact stated that while driving approximately 62 MPH, the vehicle lost motive power with the message "Reduced Engine Power" displayed, and the check engine warning light intermittently illuminated. The vehicle was taken to an independent mechanic, where a diagnostic scan retrieved DTC: P0299, indicating a failure with the turbo charger. The vehicle was then taken to the local dealer, who confirmed that the vehicle was not eligible for the GM Special Coverage: N252508360. The manufacturer was not notified of the failure. The failure mileage was approximately 82,010.

Component: Air Conditioning – A/C Hose Assembly / Refrigerant Discharge Line The air conditioning refrigerant discharge line (A/C hose assembly) appears to have been improperly designed and/or installed during manufacturing. The rubber A/C hose was routed in a manner that caused it to rest against or press against the side of the engine. Over time, the engine heat and constant contact burned a hole through the hose, causing a rapid loss of refrigerant (Freon). As a result of the refrigerant leak, the air conditioning system stopped blowing cold air, and the HVAC system no longer functioned properly. This failure was not caused by normal wear and tear, but by the improper routing and placement of the A/C hose against the engine. The issue was confirmed by Meineke Service Center through a diagnostic inspection and UV dye leak test, which identified the damaged refrigerant discharge line as the source of the leak. A significant safety concern is that simply replacing the hose does not permanently correct the problem if the replacement hose is routed in the same location. Without a manufacturer-provided redesign or long-term repair solution that prevents the hose from contacting the engine, the replacement part is at risk of failing in the same manner. There were no warning lights, dashboard messages, or other indications before the failure occurred. The air conditioning stopped blowing cold air after the refrigerant escaped through the damaged hose. I believe this is a manufacturing and/or design defect that could affect other vehicles with the same hose routing configuration. I am requesting that NHTSA investigate this issue and determine whether a safety recall or manufacturer corrective action is warranted.

I was told the bcm on my vehicle is bad. It cause my car to go all out of wack. Multiple warning lights come on (ESC, ABS, power steering, check engine), the gauge controls flutter, my gear shift clicks on and off, the car has even shut down on me in the middle of traffic, wouldn’t start, wouldn’t shift, basically wouldn’t move at all even when it did start. How would a bcm shut down my whole vehicle?

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.

CHECK ENGINE LIGHT CAME ON AND VEHICLE WAS SLOW TO ACCELERATE INTERMITTENTLY. OFTEN SLOW TO TAKE OFF AT A STOP LIGHT. SAFETY CONCERNS OF BEING REAR END DUE TO SLOW TAKE OFF. TOOK VEHICLE TO CHEVY DEALER FOR REVIEW AND THEY INDICATED AND SHOW A PICTURE OF THE TURBO BOOSTER BEING BROKEN. PER DEALER THIS CAUSED THE VEHICLE TO LOOSE POWER AND NOT ACCELERATE PROPERLY. DEALER STATED I WAS 5k MILES OVER WARRANTY AND EXISTING SERVICE SPECIAL COVERAGE NOTICE N252508360 FOR 2022 MALIBU DID NOT COVER MY VIN.

I have a problem with parking, the warning comes on,”Shift Into Park” knowing that I’m in park, so it’s not registering. Have to move the shifter a couple of times before it comes off. My check engine light stays on and then comes off a week or two later and then comes back on and no code comes up, so I’ll clear it or let it clear itself.

PI to help diagnose A/C concern

This Preliminary information communicates an issue with an OTA pending message still displayed after an OTA event and how to reset/clear the message.

This Preliminary information communicates to technicians to remove the pulley assembly and inspect the drive chain and pulley surfaces.

This PI addresses leaks from the case half and provides repair direction to dealer technicians

PIP6032B provides diagnostic direction for dealers when encountering transmission leaks

This preliminary information is to inform technicians and customers that the voice command will be inoperative when trying to open applications. Engineering is investigating and this PI will be converted to a bulletin when a repair is available.
