The two original equipment hydraulic struts that support either side of the rear trunk lid failed. It is available for inspection. The safety of my husband and I is/was put at risk because when you open the trunk, the lid is not staying up like it did, causing it to crash down on your head, back of neck, shoulder, arm, hand, etc., causing injury that is potentially fatal. The faulty parts are still in place and not inspected yet by a dealer, service center, police or insurance company. No warnings given for this faulty equipment, hence the danger of its unexpected suddenness. It started about 2 weeks ago. I spoke with General Motors, the Florida DMV and the Chevrolet dealership where the car was purchased and is taken for repairs.
