2016 Chevrolet Malibu

While driving, the vehicle experienced a mechanical failure involving the engine and lubrication system. Oil leakage was observed, and the engine began operating abnormally. This created a risk of sudden engine failure while the vehicle was in motion, which could result in loss of power, stalling, or loss of control, especially at highway speeds or in traffic. Prior to the failure, warning signs included abnormal engine behavior and fluid loss. The issue was not caused by driver error and occurred during normal operation. Continued operation in this condition presents a fire risk if oil contacts hot engine components. The problem has been inspected by a repair facility, and the failure appears to be related to a mechanical or manufacturing defect rather than wear or misuse. The component is available for inspection upon request. This defect poses a safety risk to the driver, passengers, and other motorists due to the possibility of sudden engine failure, loss of propulsion, or fire.

The contact owns a 2016 Chevrolet Malibu. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate. In addition, the vehicle occasionally accelerated independently. The contact stated that several unknown warning lights were illuminated, and the engine seized. The contact stated that the vehicle was jump-started daily, and the unknown warning lights turned off when the vehicle started. The vehicle was taken to the dealer; however, the failure was not duplicated. The vehicle was taken to several independent mechanics; however, the failure was not duplicated. In addition, the vehicle was taken back to the dealer where the vehicle was purchased; however, the failure was not duplicated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

The contact owns a 2016 Chevrolet Malibu. The contact stated that after driving and parking the vehicle, the contact entered the residence; however, upon returning to the vehicle, the vehicle failed to start. There were no warning lights illuminated. The vehicle was towed to the local dealer, and the contact was informed that the battery needed to be replaced. The battery was replaced. The vehicle was diagnosed, and determined that the camshaft, fuel vacuum pump, and camshaft sensor needed to be replaced. The Oxygen sensors were replaced. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 146,000.

The engine power reduced came light came on along with service stability trac. The car would stall after going into auto stop and just shut off. In certain instances it would shutoff when slowed down enough. It was brought in for service where the turbo charge solenoid starter and catalytic converter annd alternator all were replaced due to the turbo braking into pieces and being lodged into the converter and engine. Less than a week later the car returned to stalling at the auto stop feature. When brought in for service it was linked to the alternator and engine control module and mass air flow sensor. The car was then serviced again six months later for the alternator again. Now the car is once again stuck in engine power reduced with no direct codes linked to the problem and the starter was replaced and now the engine is remaining in limp mode. The car has stalled multiple times on not only at stop lights but on the highway and while turning at busy intersections causing traffic jams and even a side collision. The engine light as remained on since the day I got the car.

My 2016 Chevrolet Malibu Limited (VIN: [XXX] ) experienced sudden loss of power while driving on 9/11/2025 and set code P228C. The dealership diagnosed the problem as the bolts coming loose from the high-pressure fuel pump, which caused the pump to detach from the cylinder head and become damaged, requiring replacement. This failure directly matches the defect described in NHTSA Recall 18V-358 (GM Campaign 18188/18268). That recall explains that the high-pressure fuel pump can detach from its mounting due to a weld failure, leading to oscillation, damage to the fuel system, and an increased risk of fire. Although the dealer phrased it as “bolts came loose,” the result is identical: the pump detached from the cylinder head and damaged the fuel system. Despite this, my VIN does not show an open recall. GM Customer Assistance told me the repair would not be covered because of the vehicle’s age and mileage (current mileage 129264), even though recalls are federal safety obligations that are not limited by warranty coverage. I am requesting that NHTSA review this exclusion and ensure Recall 18V-358 coverage applies to my vehicle. This defect creates a serious safety risk of fuel leaks and fire.

Engine power reduced defect, causing affected models to lose power while driving at highway speeds. My son’s was driving 55 mph and then all of sudden the car decelerated to 20 mph in minutes before his 2016 Malibu stalled on [XXX]. Unfortunately the car did not make it to the emergency lane and as a result a SUV hit his car killing my daughter who was 33 weeks pregnant. The baby survived with lifelong injuries. Despite this recall, GM failed to notify vehicle owners, including the owner of the vehicle involved in the fatal accident on [XXX], in Dallas, Texas, resulting in my daughter’s death. This defect has been found in several 2016 Malibus, prompting a class action lawsuit against GM. Plaintiffs in the class action lawsuit reported having to restart their vehicles or replace faulty accelerator pedal position sensors to address the issue. GM's failure to notify vehicle owners of the safety recall constitutes negligence and gross negligence. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Brake booster pump failed ( gm part # 12704586 ) Causing limited braking and severe damage to internal engine components, camshafts ,timing chain have been damaged This is a ongoing problem in which i have had this pump replaced at my expense several times. The problem stems brake booster pump is lubricated using the engine's oil . Booster pump has a small screen to filter oil, this filter can easily become clogged resulting in booster to run dry and grenade into top of engine. These pieces then interfer with camshafts and timing gears other components
