2022 Chevrolet Malibu

My 2022 Chevrolet Malibu is experiencing the known “Shift to Park” defect and an “Air Induction System” fault. The vehicle repeatedly refuses to recognize the Park position even after moving the shifter into Park. This causes the vehicle to stay powered on, prevents it from shutting off, and forces me to shift back and forth multiple times to get the car to register Park. This is unsafe because the vehicle could roll, fail to secure, and I cannot legally leave or lock the car when this happens. This issue is widely documented on Chevrolet Malibu vehicles. GM has an established technical bulletin and extended coverage programs for this problem (example: TSB 19-NA-206 and related bulletins), but my VIN does not show access to these programs even though I am under 60,000 miles and still within the 5-year powertrain warranty window. When I contacted GM and the dealership, they admitted the defect exists but refused warranty repair unless I pay $370 out-of-pocket diagnostic fees first. This defeats the purpose of warranty and prevents consumers from getting confirmed major safety defects repaired. The warning randomly appears at different times while the car is stationary, parked, or driving. The issue has been happening consistently and appears to be worsening. I am reporting this because it is a safety concern involving the transmission and electrical controls of the vehicle, and Chevrolet is refusing to cover or recognize it under their known defect programs.

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 contact owns a 2022 Chevrolet Malibu. The contact stated that on several occasions while driving approximately 50 MPH, the vehicle unexpectedly stalled and then went into LIMP Mode with the check engine warning light illuminated. The vehicle was able to be restarted. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the turbo charger had failed, causing oil to leak into the turbo charger. The contact was informed that the turbo charger needed to be replaced. The vehicle was not repaired. The dealer was contacted. The vehicle was not diagnosed or repaired by the dealer. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 70,000.

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.

Shift to park message displays more and more frequently. Have to spend a couple minutes each time messing with the shifter to be able to turn my car off. Dealer says it is not covered under standard warranty, but I'm not paying out of pocket for a known GM issue. This should be moved up to a recall as it seems to happen more often than NOT and prevents the vehicle from powering off
