Can you flat tow a 2012 Buick lacrosse?

Answer 1

An all wheel drive.

GM claims that to flat tow a 2012 Buick Lacrosse one only has to remove Fuse #22 (Discrete Logic Ignition Switch fuse) from the Instrument Panel Fuse Block.HOWEVER, if the car is equipped with push button ignition, Fuse #22 is not there. The problem is that to flat tow the Lacrosse it must be in neutral and when in neutral the power is on in the auto. This places a 7.8 Amp load on the battery and if you flat tow for more than a couple of hours you wind up with a dead battery.

A BETTER SOLUTION is to apply power through a momentary normally-off push button switch to the M7 Transmission Shift Lock Control Solenoid Actuator in your automatic transmission. Here is how it works:-

The Control Solenoid Actuator prevents you from shifting out of PARK when your auto is not running. Thus, to flat tow your car, put the shift lever in Park, shut off your ignition and then push the button while moving the shift from Park to Neutral. You wind up in Neutral while at the same time, all the power to your auto electrons are turned off. VOILA IT REALLY WORKS. My dealer did this for me. It is an elegant solution to the problem.
