Just curious if you can confirm whether the rear hatch has a power close feature and you're experiencing it behaving with "a mind of its own", or the cold weather is promoting the liftgate to simply close by itself without power assist, due to its weight... I remember that the struts supporting the hatch on my '98 Camaro SS were next to useless in keeping the hatch up in colder winter temps.Rear hatch closes without command in cold weather. It is not under power, it just closes. Is a little bit of a surprise while removing groceries. Have any other wagon owners had this experience?
what about the other way around? I ask because in case I forgot I left the opening setting at full open. If I do that in my garage it may hit something.If the rear hatch is closing and it touches something then the hatch reverses and opens again.
