2012 Chevrolet Malibu body & structure problems

Tl* the contact owns a 2012 chevrolet malibu. While driving at approximately 40 MPH, another vehicle crashed into the front of the contact's vehicle. As a result, the air bags failed and the seat belts did not restrain the front driver and the front passenger. The contact and passenger sustained minor injuries, which required medical attention. A police report was filed. The vehicle was towed to an independent mechanic for diagnostic testing. The vehicle was not repaired.

Not a safety issue. I'm trying to find out where to file complaints about manufacturing issues to start a recall. My malibu didn't start one after work towed it to mechanic. He said it didn't have oil pressure. He opened up the engine and found pieces of o rings/rtv sealant blocking flow and busted rods, lifters, and loose bearings obviously. I have never had any one open that engine. I feel this is a manufacturing defect. Car only has 90,000 miles.
