Hey everyone, I’m Jake, and I run a dashcam supply company—so I’ve probably fielded more “my dashcam won’t work” texts, DMs, and support calls than I can count. At this point, troubleshooting a wonky dashcam feels like second nature, and honestly? Most issues are super fixable without hauling it back to the shop or panicking about a dead unit. Today, I’m breaking down exactly what to do when your dashcam glitches, dies, or stops recording—stuff I teach every new customer and rep, straight from the years of testing dashcams myself. No fancy jargon, just real, actionable steps anyone can follow. Dashcam
First off, let’s cut to the chase: the #1 most common dashcam issue? It’s not the cam itself. I’d guess 70% of the time, it’s something dumb and easy to fix—like a wonky power connection or a SD card gone bad. I’ve had customers call me in a panic saying their “brand new dashcam is broken” and when I ask, “did you check the cigarette lighter plug?” they go, “wait, no, I just thought it was the camera!” So let’s start with the basics, because skipping these wastes everyone’s time.
Let’s start with power. If your dashcam won’t turn on at all, or it cuts out randomly mid-drive? First, check the power cable—one end is the plug that goes into your car, the other is the port on the cam itself. A lot of people yank the cable when they adjust their dash, or it gets squished by a passenger’s bag, so the connection gets loose. Unplug both ends, push them in firmly until they click—don’t force ’em, just make sure there’s no wiggle room. If that doesn’t work, test the cigarette lighter port (or USB port, if your car has one) with something else—like your phone charger. If your phone doesn’t charge there, it’s not the dashcam; it’s your car’s port. That could mean a blown fuse, or just dirt blocking the contact—just grab a paper towel and wipe it out, or use a tiny bit of compressed air. Also, some newer cars have USB ports that only work when the car is on, so if you’re testing it with the key in accessory mode, try starting the engine to see if that kicks it on.
Another power-related thing: if your dashcam is hardwired (you know, the fancy setup that lets it record when your car is parked), make sure the fuse taps are correctly installed. A loose fuse or the wrong amp fuse is a super common issue here—we’ve had customers install the hardwire kit themselves and use a 5A fuse when they needed a 2A, so the dashcam doesn’t get enough power. Pro tip from our team: keep a spare set of fuses in your glove box, just in case.
Okay, next up: if your dashcam turns on, but it won’t record. This is the second most frequent problem, and 9 out of 10 times it’s the SD card. I can’t stress this enough—dashcams are weirdly picky about SD cards, and if you use a cheap no-name card from the grocery store, it’s gonna die fast, or cause glitches. First, pull the SD card out (most dashcams pop it out with a tiny button or just a gentle pull, no tools needed). Before you do anything, make sure your car is off—don’t yank it while the cam is on, that can corrupt data. Once it’s out, pop it into your computer’s SD card slot (or a cheap adapter) and check if your computer even sees it. If it doesn’t, the SD card is trash, and you need a new one—we always recommend Class 10, U3 SD cards, 16GB to 128GB for most dashcams, because they’re fast enough to handle looping footage.
If your computer does see the SD card, format it. Wait—but don’t just format it on your computer. Dashcams need their own specific formatting, trust me. If you format it on your PC or Mac, it might not work right. Instead, put the SD card back in the dashcam, go to the settings menu (it’s usually a little gear icon, or accessed via the button on the side), and look for “format SD card” or “initialize storage”. Hit that, and let it do its thing—takes like 30 seconds. That fixes most recording issues right there. Also, check if your dashcam is set to loop recording—sometimes people accidentally set it to “off” or a super long loop, so it stops writing new footage. Or if the card is full, it’ll stop recording too—loop recording is supposed to overwrite old footage, but if there’s a glitch, sometimes it gets stuck. Formatting fixes that 9 times out of 10.
Now, what if the screen is frozen, or it’s glitching mid-drive, like skipping frames or showing weird lines on the video? Most of the time, that’s a software glitch. Just like your phone, sometimes dashcams need a hard reset. Don’t panic, it’s easy. Either there’s a tiny reset button on the back or bottom of the dashcam (you’ll need a paperclip or a toothpick to press it), or you can just unplug the power cable and pull the SD card, wait 10 seconds, plug everything back in. That resets the system, clears out any temporary bugs. We tell every customer to do this at least once every 3 months, just to keep it running smooth—most people forget, so the little bugs build up.
Wait, another big one: if your dashcam is mounted on the windshield, and it’s falling off, or shaking so bad the video is blurry? That’s not really a “malfunction” but it makes the footage useless, so it’s worth fixing. The suction cup mount is the usual culprit—if your windshield is cold, or has a little moisture, or you put too much soap on it when you washed the car, the suction won’t stick. Peel the suction cup off, wash the back of it with mild soap and water, dry it completely, then press it firmly to the windshield (make sure the area is dry and free of dirt) and lock the lever on the suction cup. If that still doesn’t work, most of our dashcam mounts have an optional adhesive mount—use that instead, it’s way stronger for rough roads. Also, don’t mount the dashcam in front of your rearview mirror, where it blocks your view, but also where the sunlight hits it directly—over time, heat can warp the internal components of the dashcam, causing glitches. Mount it to the side, out of direct sunlight, that’s a quick fix for heat-related issues.
What about if it’s recording, but it says “no signal” or it’s not picking up GPS? GPS issues are usually simple too. First, make sure your dashcam has a clear view of the sky—again, don’t mount it under a shade bar or too close to the roof of your car, that blocks the satellite signal. Wait 5 minutes after turning on the car, sometimes it takes a minute to lock onto satellites, especially if you moved it to a new car or a new area. If that doesn’t work, check the GPS antenna cable—make sure it’s securely plugged into the dashcam, and not crumpled under the dash. A loose GPS cable will cause signal loss all the time. Also, if you live in an area with tall buildings or a lot of tree cover, the GPS might be spotty, but that’s not a dashcam defect—just how GPS works.
Now, let’s talk about when it’s actually a defective unit, not a user error. How do you tell? If you’ve gone through all the steps above—checked power, swapped SD card, reset it, re-mounted it—and it’s still not working, that’s when you might have a faulty camera. Common defects we see are bad power ports on the dashcam (so even if you plug it in, it doesn’t get power), broken sensors that stop recording motion or impact, or a bad display. That’s the part where you reach out to us, since we’re your dashcam supplier—we make the whole process super easy, no hoops to jump through. We test every single dashcam before it leaves our warehouse, so defects are rare, but they do happen, and we handle them fast for our customers.
Wait, let’s add a quick pro tip from our team: never leave your dashcam plugged in when your car is off if it’s not hardwired. The cigarette lighter port shuts off when the car is off, but if it’s on an older car, some ports stay on, and if the dashcam is set to parked mode, it will drain your battery. That’s a top complaint we get—people come back saying their car battery died, and it’s because the dashcam was running all night. If you use a regular plug, just unplug it when you turn off the car, or invest in a cheap timer adapter that cuts power after 30 minutes, easy.
Also, don’t forget to keep the lens clean! I see people driving around with streaks, bugs, or dirt on the dashcam lens, and they wonder why the footage is blurry or dark. Just take a microfiber cloth (the same kind you use for your glasses) and wipe the lens gently once a week—no paper towels, they scratch the lens. And don’t use window cleaner on it, the chemicals can damage the anti-glare coating on the lens. That’s such a simple thing, but it makes a huge difference in how your footage looks.
Let me wrap this up, because I don’t want to overload you. The next time your dashcam acts up, follow this order: 1) Check power (cable, car port) 2) Check SD card (format in dashcam, test on computer, replace if needed) 3) Hard reset the dashcam 4) Check mount and lens 5) Check GPS signal. 95% of the time, that fixes it. If not, that’s when you reach out to us, your trusted dashcam supplier—we’re here to help, whether you need a troubleshooting guide, a replacement part, or a new dashcam altogether. We work with individual drivers, small fleets, and big companies, so no matter what you need, we’ve got your back.
At the end of the day, dashcams are supposed to be reliable, but they’re just electronics—they’re gonna have issues sometimes. The key is to not panic, and start with the super simple stuff, not assume you need a new unit. We’ve seen customers throw away perfectly good dashcams because they didn’t think to check the SD card, and that’s a waste. So save that headache, follow these steps, and if you still have issues, hit us up to talk through what’s going on, or to get set up with new equipment if you need it. Stay safe out there, and happy driving.
