Attaching back license plate w/o drilling

I hate to be bloody honest but I would just drill it and stop worrying about the holes I’ll never see again in this lifetime.

 

That sounds like a step down: previous gens have correctly located holes with weld-nuts, for supplied stainless-steel machine screws, in a recessed zone of the hatch.

 

I was looking at the options you mentioned and found a bunch of Tesla owners using adhesive?, They had no front brackets at all? those cars are wacked..
Then I found a magnetic metal bar set that i ordered on amazon and am going to try. The front plate bracket that came with my car is so perfect, i cant imagine that there is not a similar option for the back. I don't even need the front plate so I may modify that bracket to fit the back. it is obvious there is some intention there.

I have a 2016 prius and a 2023, the 2016 has the hatch situation you are talking about and its nice. The 2023 - is an entire different kind of car than the years before: still all the positives of a prius - but it is definitely designed to be a rebranded sports car. The space in the hatch of my 2016 prius is huge compared to the 2023.: and I love them both so much.in my photo, the 2023 blue is in front of the 2016 blue.
The new car the plate is below the hatch and has a sort of specialized bracket for the front. Probably due to the 2023 being manufactured in only one of toyotas japan factories and only about 70 sent a year after expected to US. so may be the rear attachment is set for Japan and California standards for the most part.

I understand where you are coming from, however mine came with the front bracket not installed, in the trunk as my state only requires back, the front bracket is so nice, I don't understand why the back doesn't at least have some kind of care, I suppose I can rework the front bracket for the back, however, just some grommets for the holes and well just drilling on a plate in seems wrong considering the detail in the front piece.

Also, I just saw you live in Vancouver BC, That is heaven on earth. My mom and I visited in 2019 for holiday. And while the state of Kentucky especially where we live is pretty , Vancouver was just amazing. My goal is to move there someday, or just across the border on the US side. And be rid of the penny 4 ever. Thank you for posting, I have a 2016 Prius and its really a much more practical car than the 2023, but a prius is a Prius and that's the best part. Good day

 

I'm going to try these two items I saw a porche owner using on you tube - it seems a common problem.

I haven't used this yet - but will probably use the tape and magnetic, I just had my car in for a ceramic glass coating and they said the paint is amazing they had several 100,000 cars there and said they have paint that is horrible. And the prius is gorgeous, I have the blue. But good quality is expected

 

I'm probably going to let the dealer put in the self-tapping screws, but when I get home I'll redrill the holes, paint the bare metal edges, and put in nutserts/rivet nuts with stainless bolts in a standard Toyota size.

 

That does sound like the best option. I just don't have a dealership near me that im super excited to go to, and I just had car glass coated inside and out, so im going to try the adhesive magnetic? Maybe maybe not - My 2016 Prius has the holes witht he copper fitteings. Probably done at dealership - I bought is in 2017 with low miles - the 2023 I got the day it landed at the dealership.

 

My 2010 had the captive nuts on the back, but one broke free a few years back while changing plates. I got the rivet nut tool to fix it, and at least now I'll finally be able to get a little more value from a rather expensive tool. lol

 

Those holes are actually nuts; so, using the correct nut should be the way to go.
