Tesla OTA triggers false emergency braking, causes recall fixed by another OTA


Tesla’s newest over-the-air replace can activate the automated emergency braking system with none want for braking, growing the danger of a rear-end collision, the NHTSA disclosed Monday. The 11,704 affected automobiles throughout the electrical automobile maker’s lineup got here geared up with its misnamed “Full-Self Driving” in Beta testing mode. Tesla patched by means of one other over-the-air replace to repair the problem. 

Automobiles working firmware launch 2021.36.5.2 despatched over-the-air (OTA) on Oct. 23, 2021 have been subjected to false forward-collision warnings or automated emergency braking occasions underneath a sure sequence of occasions. Tesla canceled the replace for automobiles that had not put in it, disabled the affected programs on these automobiles that did set up it, after which reverted the software program to the closest obtainable model, the automaker mentioned in submitting with the NHTSA.
