The use of lightweight bumper materials on some car models means that bumper mounted hitches can no longer be used on these models.
Inability to use a bumper hitch does not mean a trailer cannot be towed. It does mean that at least a light weight frame/body hitch is required.
The following table indicates 'Yes' you can use a bumper mounted hitch, or 'No' you cannot use a bumper mounted hitch.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
