NHTSA Complaint #11491362 — 2018 CHEVROLET MALIBU

What component or system failed or malfunctioned, and is it available for inspection upon request? A defect in the cam shaft solenoids causes a notice that "Engine Power is Reduced." At that point, the engine begins to struggle to accelerate from a stop, and from increasing speed while on the highway. How was your safety or the safety of others put at risk? The unpredictability of the defect and its affect while driving poses a large threat to safety, particularly on the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The dealership service rep not only confirmed the defect, but also confirmed that the issue persists across multiple GM models yet no recall exists. Again, this is a KNOWN defect with GM engines, as confirmed directly by the dealership. Despite this, no remedy was offered, I was told it's neither covered by my manufacturer's warranty or recall. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. I was given a video explanation of the issue and also told directly of these persistence of the defect across multiple lines. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning prior to the failure. The defect and "Engine Power Reduced" message both first presented in March of 2022, less than a year into my ownership of the car -- and while my car was still under its 60,000 mile warranty.
