I'm confused-- these seem like 2 totally separate issues. The Model 3 issue doesn't even sound like a trunk latching issue, it sounds like a cable-harness-in-a-hinge issue?
I actually have a Model 3 that exhibited an annoying rear camera problem (now fixed). It had to "go in" to be fixed 3 times, for complicated reasons, but I found the ultimate fix (an OTA update) to be annoying. I had read on the forums that harness damage was not-uncommon, particularly among people who had installed a power trunk closing retrofit and somehow managed to damage the harness in the process (oops!)
Basically:
* When the car was new, rear camera did turn on 100% of the time, but failure rate was pretty low. The car had a few minor bugs and the camera seemed to be one. Within a few months most of the bugs were sorted and I had no regular issues with the camera anymore. (way less than 1% failure rate I'd say -- not unlike I've noticed in other cars).
* ~ April 2021 the camera started failing to come up with some regularity, immediately after a software update, so I suspected a bug, and just waited for it to get fixed. I think it basically never worked at this point. But it didn't get fixed in the next few updates. (this was when the car was 3 or 4 years old)
* A few months later, I took the car in for its final "warranty about to expire" visit. Probably the car's 2nd time at the service center in 3 years? I mentioned the camera along with a few other minor issues. They said they'd replace the harness through the trunklid if they had one, but thought it was out of stock. Sure enough, it was out of stock and they never 'fixed' it.
* Mobile service visit, came to my house and replaced the harness in about 20 minutes. But it didn't solve the problem. The tech said likely the FRONT coax harness would need to be replaced, which was much more involved and would require a service center visit.
* Scheduled service center visit.
* The night before the visit, they called and said "hey, is your camera fixed? We pushed an update". Well, I don't know. Even if it IS working, 12 hours isn't enough to tel whether an intermittent problem is permanently fixed.
* Took the car in, they examined everything, said it was fine, and it has been ever since.
The car's been relatively trouble free but I want to say this is the second time (possibly for the same camera issue) someone at Tesla pushed a update to the car the night before a service center visit, in the hope it fixed the problem. Why not prioritize these fixes for, I don't know, a few days before the visit, if you want to fix things OTA and limit the load on service centers?
- cududa 5y agoQuite possibly completely unrelated, but I do recall helping some friends analyze build defects on early Model 3’s and making some comment like “boy I hope none of those high voltage lines [in the same harness] are ever active when the lv ones are [due to non-existent shielding and routed to the same MOLEX]”. If memory serves it was power and data over 20 gauge wire intertwined together, unshielded, and pretty much every compute component in a Tesla uses Ethernet as a common bus. Could easily see the back harness being a single package where power for rear defroster, lights, and camera data were housed together. Lights! Camera! …no action
