tow 4 down

Years 2010 and 2011 manufacturer said yes, not to exceed 65 mph and start engine and run the engine at fuel stops to lube the trans. I towed a 2011 for approx. 20k miles. Only problem I had was an occasional dead battery. Added a "toad Charge" from ISL products and no more issues. But and again I say "BUT", year 2012 with same engine and trans. they no longer said it could be done so they may have discovered some thing. So I bought a Jeep as my toad but still have the Lacross. If you decide you still want to do this I have a Road Master base plate for 2011 lacross I would be willing to part with, PM me if interested.

Actually, it can be. see page 16

Check the owners' manual...that doesn't sound like one of the GM products that can be towed 4 down...
