- An increasing number of Tesla owners report issues where many car features stop working.
- The problem appears to affect only cars with hardware version 4, and the fix remains unclear.
- No recall or service bulletin has been issued to address this growing issue yet.
Imagine getting to work a few days or weeks after buying a brand new Tesla only to realize there are major issues. The cameras aren’t functioning, the GPS still thinks you’re sitting at home, and features like emergency braking don’t work. That’s exactly the type of situation that a number of Tesla owners are dealing with right now.
Several of these drivers claim to have taken delivery within the last month or two. This detail is important not just for the inconvenience it causes, but also because it might point to the root of the problem. These owners report that they all have Tesla’s AP4 or hardware version 4 chipset, which is responsible for the features mentioned above. If it has a problem, those features won’t work, so it could very well be the crux of this whole situation.
Glitches, Delays, and Angry Owners
Over on Reddit, several owners report very similar symptoms. On top of that, they claim that Tesla service centers are routinely scheduling to swap out AP4 hardware and delaying appointment times.
“Happened to me: 2024 Model Y. Navigation shows me at home. All the time. Cameras out. Even the display does not adjust. Auto lights don’t adjust. Appointment on January 13 wayyy delayed,” said one commenter.

“I was contacted by Tesla today and the tech from my local service center told me that Tesla has told them to stop replacing the computers until they get to the root cause. He said they’re going to try and fix it with a software update and to expect 30 days. I find this mind-blowing because my symptoms started happening on Dec 2 and now my service date has been pushed back to Jan 23, nearly 2 months later,” said another.
There are many more complains on forums, including this one: “After a software update pushed by Tesla, the AP4 computer in my 2024 Tesla Model Y shorted out, causing a complete failure of all systems controlled by this computer.”
So, What’s Actually Wrong?
Electrek reports that sources from inside Tesla say that it’s related to a short circuit: “The cause is still being investigated, but one source told Electrek that one of the possible causes is the low-voltage battery short-circuiting the computer during the camera calibration process.” According to the outlet, one source claimed that Tesla Service has a mandate to “to play down any safety concerns related to this problem to avoid people believing their brand-new cars are not drivable.”
That seems like a tough job for Tesla Service employees considering how much emphasis the brand itself places on touting its safety record and technology. Notably, the NHTSA currently requires cars to have a functional backup camera, so it’s strange no recall related to this issue has been announced. That could change any day, but it’s also possible that Tesla will send an update that will fix the problem remotely, if it’s software related.
We’d ask Tesla, but, well, they don’t have a press department, though it appears that they might’ve recently hired one, as you can see from this Linkedin posting. We’ll keep an eye out to see if they decide to actually say something.
