2024 Prius Problems continue

I don't think there's any real securing points at the front - it's a protruding piece. But as it flips up it has to flip from convex to concave because of the curve of the fasteners at the back, so it's got to buckle somewhere, I think.

On the sticky stuff, there's no evidence in the pics that the tape has given up.

Looking at the first picture - I hadn't really paid attention to it - it looks like the inner grill has broken. So it's not just the bar coming loose, but I guess given enough weakness somewhere, other parts properly fastened can get torn off.

Designers were likely relying on the curve of the piece to provide the strength to help keep it place.

This is the OP's second Prius, it might have the updated part. Looks like those side clips were just pulled out when the bar flipped to concave. Perhaps the heat softened the plastic they anchored too, or weaken the tension of the clips. Being left off to begin with is another possibility.

I was assuming the "dent" was a crumple as the result of the piece being forced up by the airflow - maybe indicating where remaining fasteners were putting up the last bit of resistance before breaking.

the “dent” is a warp from it being hot and bent. But yes you guys are correct the previous owner had the emblem painted (or swapped). Can’t see why you would take the bumper apart to do that.

Thanks for all the insight guys. I haven’t had time to take it in. But I will soon. Yes it was VERY hot out through the desert. I believe it just got weak from heat, soft, and with the hours of constant 80mph wind, it buckled. Obviously I do not know with certainty if the previous owner did anything but the car is in perfect condition with 7k miles. Emblem shouldn’t have anything to do with it. Will report back. And and my previous Prius Prime, well it had a dead battery when I test drove it. I did find it odd but they got a battery pack and I knew it was warrantied but ya ended up wasting a ton of my time. Got all my money back but still. 3 months later.

newly repaired bumper, this time no place to fasten the clips, and the wings are moving loosely.

Spent a little while looking at the parts diagrams. The main "front bumper bar" as they call it could be either metal or plastic from the diagrams; it seems the design changed in June 2024.

There are screws and clips securing it to the inner grill in the centre, towards the back, and also dashboard-type clips securing the wings to the lights. It may also be supposed to clip in to the outer grill at the centre front, but there are not major retainers there.

Those 8 end clips up until June 2024 were plugging into separate retainer parts attached to the main bar with double-sided tape.

According to the parts catalogue, from June 2024, those taped retainer parts and the clips no longer exist (footnote 3), and the bar has a new part number. I don't see a corresponding change for the headlight part I think they clip to, so I'm going to guess the 8-clip retaining mechanism is now integral with the bar. (The repair manual has not yet been updated for the parts change, only showing the separate retainer).

So maybe there is a known problem with double-sided tape failures on the ends, and that's what OP encountered?

(Edit: although if the tape failed, I'd expect to see a retainer left plugged into the headlight, and we don't. Are the retainers present at all?)

i have a newly repaired bumper, this time no place to fasten the clips, and the wings are moving loosely. I uploaded the short video in youtube but I cant share in this forum yet. Not sure what the remedy will be and I just hope it doesn't keep moving in highway speeds

So did you get a replacement front bumper bar? If you got part 52111-47901, that doesn't include the retainers, so those should have needed to be refitted from the old one.

(Can you really re-use the adhesive? I wouldn't have thought so, but the instructions I posted above seem to suggest it's possible.)
