Repair kit or just replace the ladder, what would you do?

I think you are overthinking the 'maybe it's fine' angle. When you are working at height, you cannot rely on a 'mostly working' mechanism. It doesn't matter if the lock just needs lube or a good jiggle; the entire design of that multi-position system hinges on that specific internal component holding under maximum load. My rule has always been simple: if a critical safety feature is compromised, the ladder is retired. I had an adjustable aluminum platform riser fail once, not because of a manufacturer defect, but because a piece of debris got caught in the track and created uneven pressure points. It was completly negligible til I placed full weight on that side. The damage was permanent, and it taught me that even minor, intermittent failures are catastrophic when gravity is involved.

Regarding the repair kits, honestly, the hassle of shipping it back and waiting is far less stressful than the potential consequences of relying on a compromised locking pawl. Look at it this way: the manufacturer is replacing the risk. Don't treat a critical piece of fall prevention equipment like a wobbly rung that can be sanded down.

I've had a few of these telescoping units that had similar locking concerns, and I think the absolute replacement rule is too rigid for the average guy. It’s not always about the hardware being totally shot; it’s often about wear and tear on the pivot points. When I was doing some electrical work on a barn last year, my old ladder started shifting a bit, and instead of tossing it, I had it thoroughly inspected by a structural maintenance specialist. They didn't replace the whole unit. They took the locks apart and replaced the internal pins and adjusted the tension springs. It cost me more than a full ladder, but it gave me peace of mind that the rated load capacity was accurate again. This is my take: if a certified profesional can diagnose the failure and fix the internal mechanism, that's a valid path, provided the repair uses OEM parts. It's about restoring the engineering integrity, not just slapping a label on it. I understand the hesitation about something failing under load, especally with adjustable gear. But simply abandoning a perfectly functional ladder because of a manufacturing defect in one specific part feels like overkill for many of us. If you decide to keep it, always ensure the locking bar is fully engaged and that you never stand on the top two rungs. Safety is about the entire procedure, not just the initial assembly of the aluminum. My experiance suggests that a factory-approved repair, backed by a proper inspection, is a perfectly reasonable alternative to sending a hundred-pound piece of gear back to the manufacturer.

There's a middle path nobody's touched yet. I did a recall repair kit on a garage door opener a few years back, and it was actual replacement hardware in the box, not just a warning sticker. Took me about 30 minutes with a socket wrench and a couple YouTube videos. So read the fine print on this one before deciding, because 'repair kit' can mean diffrent things. Also, match the model and serial number off the sticker on the rail, not just the size, since these adjustable ladders come in a dozen variants and the affected lots are specific. If the kit turns out to really be just labels and a lubricant packet, then yeah, I'd push for the replacement instead.

This thread is making me sweat a little because I bought mine secondhand from a neighbor a couple years back. No box, no receipt, and honestly I never registered it with the company when I got it. The hinges on mine still click into place nice and firm but now I'm wondering if that even matters. If a model gets recalled, does the company still honor the fix when it was the first owner who bought it and you just took it off thier hands?

Not sold on the garage door opener comparison a couple posts up. A door opener recall fix failing means the door jams or sags, annoying but you're standing on the ground. A ladder lock failing means you're 12 feet up concrete. The stakes are so different that 'I did a similar recall kit in 30 minutes' doesn't relly tell you anything about whether this one is safe to DIY. I'd want to know specifically if Little Giant's kit replaces the actual pawl hardware or just adds stickers and instructions, because those are two very different kits wearing the same name.

Funny how these threads always circle back to the same place. I'm 64 and my go-to for anything over about 10 feet is still the old wooden extension ladder my father gave me. Heavy as sin, no hinges, no buttons, nothing to fail but a rope and a pulley. I keep the folding adjustable one for low stuff around gutters and shrubs where a slip means a sore ankle, not a stretcher. There's something to be said for hardware you can eyeball in ten seconds and know is sound. Different ladders for different jobs, that's how the old crews did it.

Update: took the garage door opener guy's advice and actually read the fine print before deciding anything. Turned out my model WAS on the list after all, I just hadn't dug deep enough on the lookup page. The repair kit showed up last week and it's real replacement hardware, not a sticker, so I swapped the hinge parts myself in about half an hour. Lock clicks solid now. Secondhand buyer, no registration needed either, they just asked for the date stamp.
