FWIW, I've owned three SanDisk Ultra 32GB red and grey cards. I purchased them between 2010 and 2012 long before I ever became aware that they were problematic in dash cameras.
The thing is that all three have performed very well. Two of them abruptly died on me though, but I can't say for sure whether they were manifesting the known issue where they suddenly flip to read only. They simply died and could no longer be read or written to. I couldn't even mount them on my computer for testing. There is a very high likelihood that they simply died of old age with many, many thousands of dash cam recording hours on them.
Here's the interesting part of the story. The third SanDisk Ultra card I own which was purchased back in 2012 is STILL in daily service. After years of using it in several dash cams I took it out of everyday use just in case it might fail on me at a bad moment. Not wanting to waste a perfectly good memory card I started using it for testing purposes with the knowledge that if it should suddenly failed on a test cam it would not be a big problem. So, I spent nearly a year using in a Mobius 2 I was testing for the developer and it performed flawlessly the whole time. Then I started using it in one of my Mobius 1 cameras with a varifocal lens installed and it again performed flawlessly for well over a year. About six months ago, when I started using my varifocal telephoto lens equipped Mobius full time in my truck I decided to stop using the SanDisk card in that camera, again not wanting any unpleasant suprises and so I installed it in one of my side mounted cameras (experimentally) where it is in daily service and still performs perfectly. I keep expecting it to fail at any moment but it just keeps going and going. The whole experience is almost weird at this point! That SanDisk Ultra card has thousands and thousands of hours of recording on it and it has now been in regular dash cam use for over six years! Go figure!
