As manufacturers are producing cheaper microSD cards there is a move to cheaper TLC memory (also known as 3 bit MLC) which although can work short term may not last as long as expected and results in warranty RMAs where possible from the vendor / manufacturer.
For some people the TLC cards may even outlive the dashcam - it all depends on use types etc.
Usually this problem appears as a card flipping to read only mode - this is a protection mechanism designed to make sure that even if the card is starting to suffer memory failure you can access your data.
In the event of a dashcam you're probably not so bothered about that, but if it was your holiday pictures or photos of your family you'd appreciate that function more.
Dashcams are quite heavy users of memory cards as they're always writing - TLC memory cards are great in things like phones or media players where they're mainly reading, but they're not so well suited to writes and will fail earlier than MLC or even SLC cards.
If you don't do much driving then you'll probably never have an issue with your TLC memory cards - if you've got a dashcam that has parking modes or is recording full time then at some point you'll probably come across these issues.
This post is just to give a quick reference of what cards are currently known to be MLC - these all carry a price premium as they're a higher quality product that will last longer and usually have a longer warranty.
In addition to these cards there are also industrial microSD cards available from various vendors but these will cost even more than the cards below.
As of March 2015 the list includes (originally taken from http://ourberries.com/2014/09/16/microsd-round-reviews-giveaways/):
Barun Electronic’s Gold Flash PRO (64GB) MLC
Memorette (memento) Standard premium (8GB) MLC
Lexar High-Performance UHS-I cards [300x] (64GB) MLC [LSDMI64GBBNL300A]
Lexar High-Performance UHS-I 633x MicroSD (64GB) MLC [LSDMI64GBBNL633R]
Samsung PRO [New 2014 Series] (64GB) MLC [MB-MG64DA]
Sony High-Speed R95 UHS-3 (64GB) MLC [SR64UXA]
PNY Turbo Performance High Speed MicroSD (64GB) MLC [P-SDUX64U190-GE]
Transcend Ultimate 600x UHS-1 (32GB) MLC [TS32GUSDHC10U1]
Please add any more cards that are confirmed MLC to this list!
