A bug in Tesla’s software is being addressed by the company after TMC members found they were unable to engage Launch Mode and Max Battery Power features on their vehicles.
Tesla inadvertently removed the features from some Model S vehicles after a UI update. The company said it is working on a fix and apologized to owners for the inconvenience.
TMC Member Ryan Autry surfaced the issue in early April regarding his Model S P90DL.
“Anyone else with a Performance model missing Max Battery Power after the latest firmware update?
The Ludicrous+ tab is there, however Max Battery Power is not displayed and the fans don’t come on at all. Launch Mode also doesn’t work.”
As more members commented with similar findings, it was discovered that the issue is mostly affecting P85D and P90D models. Owners also discovered their vehicles producing less power after installing the 2019.x update.
Understandably, owners are anxious for Tesla to fix the problem:
“Issues like these are hard to look-over and accept, especially if its now been over a month and still nothing from Tesla.” nividia7
“Tesla, please fix our cars!” merq
When you pony up thousands of dollars more for Performance, you need to be able to use it. And, it’s a bit surprising Tesla hasn’t delivered a fix since the issue was reported more than a month ago. In the meantime, it’s great to see the TMC community sleuth out issues, which hopefully helps get them fixed sooner.
