I currently tow 4-flat my 2017 Malibu with the 1.5 engine.
You cannot tow 4-flat the Malibu Premier 2.0.
I had to install an additional interior 12V socket wired directly off my battery to power my Brake Buddy as the factory-installed 12V outlets have no power to them 10 minutes after the engine is shut off.
I also had to make up an LED light bar to place in my rear window deck to indicate turn signals, brake lights and running lights. This light bar is powered direct from the electrical cable from the motorhome. The reason for the light bar creation is that the tail lights on the Malibu are LED and splicing into the tail light wiring could create electrical problems and could possibly void your warranty. I can email a picture of the light bar upon request.
Lastly, I do have a disconnect switch installed to preclude pulling the fuse.
So far, so good.
