I’ve had I’d guess a dozen lockup’s in the past 15 months. It seems to occur when I’m shooting a sequence of a lot of images. This past Saturday I was shooting gymnasts on a trampoline in slow speed continuous and it locked up. Battery out then in and it was back working. I use a Sandisk 128GB CF Express card bought from B&H so I have to believe it’s not counterfeit.

I sent it in for repair although I’m not optimistic they actually know the root cause. The survey says 50% have experienced a lockup. That seems extremely high to me and cause for concern.

I hope this does not turn into another bad experience with Canon. My last was the 1D Mk III focusing problem. It was never resolved fully. My 5D’s were all pretty rock solid.

Bought my R5 in June and RF 100-500 in July. Shooting manually, using Canon and non-Canon batteries, high-end CF Express and SD cards (Raw and L jpg) at the same time, etc. I have only experienced freezing when using the RF 100-500 and shooting in rapid-fire mode. While inconvenient, I can probably live with it as a) it doesn't happen regularly; b) it's an easy fix (pop out the battery); c) haven't lost any data and d) I do not want to be without this camera for an extended period as others here have sent their cameras in only to experience the same issues later. If Canon decides to do the right thing and have a recall. then I will consider sending it in.

Mine has frozen twice in about 50,000 shots now - and it just required switching off and back on, and not removal of battery. It's not going in for service.

my R5 will freeze and actually will lose the shots in the buffer. I have not been able to pin point the cause as it happens with various lenses and setups. very frustrating. It freezes and comes back, but drops the shots.

As there are several reports now of the R5 freezing and requiring battery removal and replacing to restart, let’s get some more information on what proportion of owners have the problem.
I've had mine for over a year now and the only freeze was the first time I put my 100-500 on it and got Error 70. That happened once. I think a lot of this is memory card related.

My R5 has been working fine for months until today. I had been out shooting on and off for an hour or so and then took some video until it froze. It was locked in place as if it was still recording. I switched it to power "off" yet it continued to read as if it was still recording. Aside from the display info, the screen was black and wasn't trying to focus on anything. After a few minutes of resting the camera as I was trying to be patient, it seemed to feel a bit warmer. I worried it may overheat, so I removed the battery. It's back to normal now, but that was very odd. I did not get an overheating warning at all prior to this. The attempted video was not recorded at all.
