Just bought vehicle and was made aware of the problem before we bought it. I just read on this site that the power liftgate module software has to be updated. I will let you know if that fixes the problem.
Had the same problem this weekend on thursday i could not get the liftgate to unlatch regardless of the method used. than on Sun night it was working fine????
Power lift gate not always reliable
the power lift gate works sometimes and sometimes not.
lift gate can fail to several times and then work for several days. It fails to latch or unlatch like it is caught.
