Troubleshooting Tips If Tesla Model 3s Lose LTE Connection for More Than 2 Days
Tesla Model 3s are equipped with LTE technology, which allows for a reliable connection to the internet. However, some users have reported that their cars have been without cell service for up to two days. This could be due to a software glitch or hardware failure. To troubleshoot this issue, users should first check if they are on the most recent version of software and reboot their car's MCU. If this does not solve the problem, they should contact Tesla Service to determine if the issue is related to AT&T or Verizon service in the area. Additionally, they can ask neighbors if they have experienced any issues with their AT&T service. If all else fails, it could be due to a major outage in the area or a bad LTE module or antenna.
In order to prevent this issue from occurring again, users should ensure that their car's software is up to date and that they are using the most recent version of the Tesla app. Additionally, they should check the signal strength in their area and make sure that it is strong enough to support LTE service. If the signal strength is weak, they may need to move closer to a cell tower or use an external antenna. Finally, they should contact Tesla Service if they experience any further issues with their LTE connection.
If users are unable to connect to the internet for two days or more, they should not panic. Instead, they should take steps to troubleshoot the issue and contact Tesla Service if necessary. Additionally, they should ensure that their car's software is up to date and that their signal strength is strong enough to support LTE service. By following these steps, users can help ensure that their Model 3s remain connected to the internet at all times.
What could be causing my Model 3 to have no cell service for over two days?
It could be a software glitch, or the LTE module or antenna may be bad. Check with neighbors to see if anyone has AT&T service and if there are issues in the area. Also, make sure your car is on a more recent version of software (2022.4 or later). Try rebooting your car's MCU and see if that solves the problem.
Does my Model 3 have 3G or 4G?
All Model 3s came with LTE, but Teslas with LTE had a software issue where the modem would try to make initial contact using 3G before switching to LTE, and if that initial contact failed, it would stop working. That was fixed way back in software version 2022.4.
Are there any reports of AT&T or Verizon loss of service during this time?
No, there were no apparently AT&T or Verizon loss of service reports during this time. However, it is possible that the issue could be localized to your area. Check with your neighbors to see if they are having any issues with their service.
What should I do if I'm still having problems?
If you're still having problems after rebooting your car's MCU, try resetting the LTE module by pressing and holding the power button for 10 seconds. If that doesn't work, contact Tesla Support and they can help troubleshoot the issue. They may need to send a technician out to inspect the antenna or replace the LTE module.
