The failure pattern on these older Glenburn doors tends to follow the climate more than the age. This area sits in a cold, severe climate band, and steel panels - especially older, thinner-gauge ones without foam backing - contract hard in deep cold. A panel that's already dented or has a hairline crack from a mower or a bumper tap will often split clean through on the first real cold snap, right along the stress line.
You'll usually see it first as a gap at the bottom corner of a section, or a panel that bows slightly when the door's down and the garage is unheated. On insulated doors from later in the build range, the failure shows up differently - foam crumbling at the seam rather than the steel skin splitting.
Either way, a single bad panel on an otherwise sound door, sound opener, and sound track is worth fixing on its own. If you're also hearing grinding at the rollers or the door's been dragging on one side, that's a separate problem layered on top, and it's worth mentioning when you call so the right truck and the right parts show up the first time.
