We are told that a 2013 Malibu with auto tranny can be towed 4-down. I look on the 2013 Dingy tow guide and Malibu is not listed. The dealer checked and was told it can be towed. What is the real deal...
The Owner's Manual that comes with the car should tell you how to tow the car. It will be specific not to avoid the warranty.
Just found this in the Owner's Manual, pg 10-93.
Notice: If the vehicle is towed with all four wheels on the ground, the drivetrain components could be damaged. The repairs would not be covered by the vehicle warranty. Do not tow the vehicle with all four wheels on the ground.
