Check for some rubber stoppers on the hatch portion towards the rear of the hatch. The Gen 1 Volt has adjustable stoppers...Gen 2 probably does too.Has anyone else with a 16/17 had problems getting the trunk to latch? I don't want to slam the trunk so hard I shatter the windows (or generally abuse the car or make noise), but if I don't, about 90% of the time it doesn't completely latch and I get a notice when I start the car.
