I've been through several SD cards, including Sandisk Extreme Plus 190Mb/s 128GB v30. The Dr will just stop recording whenever it feels like it. Is there any permanent solution to this yet?

Mine is set to record as a dashcam.
Set to overwrite old files.

I went on a drive today and stopped three times.
First segment recorded the entire drive
Second segment recorded the first 60% of the drive
3rd segment recorded the entire drive

I really wanted that whole 2nd segment recorded. I am so *expletive* tired of this PDR failing all the time. There has to be a solid solution by now.

 

What year is yours? I've had my PDR set to record since I got the car, and it has always worked. I haven't pulled the card itself lately to see for sure, but the red "dot" showing PDR active is on the display. Pretty sure I'm using a Sandisk Extreme as well, mine is a 2025. Is the PDR active dot always showing good but it's not actually recording? If so I'll pull my card next time and see if it's actually been recording all along

 

What I found for mine that was doing the same! Bought SanDisk From Amazon. A significant % of Amazon Flash Drives, SD Cards etc are bootleg copies, ones that failed to meet specs etc. Crooks are smart they copy or buy rejects of the high market share Brands. Buy from a known local source, like Best Buy etc. Also buy one designed for surveillance camera's that can be written over many times.

Worked for me.

 

Had same issue for a while, replaced Card and it has been better.

 

If buying from Amazon, make sure it is being sold and shipped by Amazon, not a third party. There are multiple sellers of SanDisk (and other memory cards) on Amazon.

 

How long are you recording for? I believe the single file size is limited to 4GB which equates to around 90-100 minutes.

 

Interesting.
AI response agrees with your statement:


However, looking at actual files from my SD card sorter by size:



My car is a 2024 HTC. Go figure...

 

I know FAT32 has a 4 GB file size limit but exFAT and NTFS have a much larger file size limit but I don't know what formats are acceptable for the PDR, different years may have different requirements. OP, what size are your files and how is the SD card formatted?

 

I had the same issue recently. I have a few different SanDisks, I think all were from Amazon other than the one I got at Ron Fellowes. I swapped out the card and it's been working since. Wondering if a bad/counterfeit card was my reason.

 

Quoting Google AI:
Yes, counterfeit and defective SD cards are unfortunately a known issue on Amazon.
These scams fall into two main categories:

• Fake Capacities: A lower-capacity card (e.g., 32 GB) is reprogrammed to display a massive storage size (e.g., 512 GB) on your computer. Once you fill the card past its true limit, files will start corrupting or overwriting themselves.
• Defective/Slow Speeds: The card may physically hold the advertised amount, but uses incredibly slow, low-quality memory chips that fail prematurely

That latter reason is what probably caused my issue with an Amazon purchased music flash drive!

Details of issue I worked for ~6 months with my new 2020 C8 trying to solve that others also also reported. About 1/3 of the time I started the car got the message saying the USB drive did not load. I tried solutions offered by members. One was a help as after having the same issue the membered found the Flash Drive was loading on the same Buss as other things. He found if he reduced his music file size it solved the problem.. I tried that and found it helped but still had the issue 10+% of the time.

At the dealer I asked the Tech who reloaded the Infotainment software. After several starts, same issue. He then checked the GM Service info and found a Tech had posted that IF it is a SanDisk Flash Drive that could be the issue! I asked WHY as they are probable the Market Leader? He said it's common for Techs to post what they find without speculating the possible cause.

My industrial experience with parts copiers supplying "copies" of our Genuine, Registered Trademark Heliarc products is the one all copy. In our case not using our Heliarc name but our torchs, gas lens etc after our patents had expired that is what they sold. In fact on Amazon now you can see the wear parts, collets, collet bodies etc all with our old part numbers at very cheap prices. Before I retired we had checked some and found for that because of high temperature exposure where used expensive Beryllium a Chrome copper there were just made form plain copper or cheaper alloys.

So I bought this Flash Drive and my 6 month search for a solution. If you can buy directly from the manufacturer or as I now have for this type products, Best Buy in town, lower risk.

 

If you suspect a card is fake it can be tested with this utility:
https://h2testw.org/

 

No joke, I use h2testw.exe on every card I buy. On a big card, it will take a long time, but you will know if the card is performing correctly, and that all sectors are working properly.

Also be sure to get a card with high enough write speed. h2testw will tell you that, too.
