Has your Model S radar been disabled? Let us know in the comments below. Or don’t take your car in for a service visit. It appears the only way to keep the radar connected in your 2021-2022 Model S is to be running 2022.20.8 or earlier as the 2022.20.9 version was the one that disabled radar. From what we have been told these Model S and Model X cars have the upgraded hardware, but the software to take advantage of it has not been developed and are therefore not using the new radar units. What makes the disabling of these radar units strange, other than the explanation that it is to increase range, is that Tesla is now shipping Model S (and Model X) cars with an upgraded high-definition radar unit that forms part of Hardware 4.0 (HW4). Since the service bulletin was issued numerous other refresh Model S owners have replied saying their radar units were also disabled during service visits for other reasons, with some saying their Homelink was mistakenly disconnected at the same time. Other reason provided was that the units are susceptible to water ingress and can become damaged, but if they aren’t being actively used anyway why go to the effort (it requires removal of the front bumper) and expense of removing it in the first place. And with Tesla Vision now handling all of Autopilot and active safety features, there is no need to keep it connected. When inquiring further about the bulletin with an employee, it was explained that is a proactive fix from Tesla and that while the bulletin doesn’t exactly outline why but one reason given was that they still consume energy and the vehicle’s range might be increased without it connected. Along with being disconnected the car’s software is updated to trick it as if there is no radar there. The topic of radar has popped up on the Tesla Motors Club forum, where user ‘black night 3’ said last month the automaker had issued a new Service Bulletin for his 2022 Model S to disable the front radar. So far the disabling is limited to the 2021-2022 Model S running software 2022.20.9 or later, with employees explaining it is being done because they are no longer needed after the switch to Tesla Vision. In some cases, water may even escape from the openings of the liftgate itself, as shown in the video embedded below.Ī service appointment should fix the issue permanently this time around, with Tesla saying that the repair can be made either at a Service Center or via the company’s Mobile Service crews.Īs always, we’d like to know what you think about this, so head over to the comments section below to give us your thoughts.Tesla has started disabling radar sensors from some vehicles during routine appointments at Service Centers.

Now it looks like Tesla will use a different sealant to possibly stop the problem from reappearing. Although the instructions for the fix aren’t detailed, looking at the list of required parts, it seems that Tesla will replace the liftgate lamp double-ended stud gaskets and the liftgate lamp connector gaskets, as well as using some Loctite hybrid polymer and sealant to prevent further leaks.Īccording to Drive Tesla Canada, the American EV company has been aware of this issue for a while, but some owners who went to service their vehicles the first time had to return a few weeks or months later because the issue had made a comeback. This procedure is aimed at service technicians, and it looks like the amount of time needed to complete the repair is 1.8 hours, according to the service bulletin. If this symptom is present, reseal the liftgate assembly. Inspect inside the trunk area for signs for water leaks that came through the liftgate assembly. The document (SB-23-10-003) is dated Apand says that “water may have leaked inside the rear trunk area through the liftgate assembly,” with the correction of the problem being described as follows: Tesla has issued a new service bulletin as it tries to address the problem of water ingress that appears on 2020-2023 Model Y crossovers built at the Fremont and Austin Gigafactories.
