Suspension Noise problems of the 2016 Chevrolet Malibu

My car won't shift into park sometimes and the suspension is making a poppin noise and my cruise control is not working.

The contact owns a 2016 Chevrolet Malibu. The contact stated that while driving or pulling off from a stop, there was a knocking sound coming from underneath the rear of the vehicle. The vehicle was taken to ourisman Chevrolet of bowie (16610 governor bridge rd, bowie, MD 20716), and was diagnosed that the rear suspension knuckles needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but offered no assistance. The failure mileage was approximately 96,990.

There are several hundred complaints online about a thumping noise coming from rear of 2016-2018 chevy Malibu of all trim types, particularly at low speeds or when one side of rear of vehicle goes over small bumps. Gm put out a service bulletin recommending that dealerships and service technicians add a washer to top of both rear shocks and possibly replace rear suspension knuckles. Many dealerships give customers �the runaround�, requiring them to pay for diagnostic fees and repairs, performing other repairs and replacements that do no fix the problem, and telling customers to just deal with it. This rear knuckle part is on a national back order, causing delays of approximately 6 months for the safe and timely repair of this issue. Without these washers on the rear shocks, the top of the shock makes physical contact with the bottom of the strut mount, causing the suspension knuckle to fail, which then causes bushings to fail. This is a very serious safety hazard that Chevrolet is largely ignoring.

The rear suspension of our car started making a metallic popping noise when we drove over bumps or accelerated from a traffic light. The sound also occurred when someone sat in the rear seat with the car parked. Integrity Chevrolet of chattanooga, TN determined that both knuckles in the rear suspension needed to be replaced. The service writer told me that if this had been left unaddressed, it could cause a safety issue as there was metal rubbing against metal.
