"The degradation detection system 'fails to detect and/or warn the driver appropriately under degraded visibility conditions such as glare and airborne obscurants. In the crashes that ODI has reviewed, the system did not detect common roadway conditions that impaired camera visibility and/or provide alerts when camera performance had deteriorated until immediately before the crash occurred.'"
"Tesla began developing an update for the degradation detection system in 2024 after a fatal 2023 incident, but Wednesday's NHTSA filing states that the ODI doesn't know which vehicles have received the update. However, the update may have been able to prevent some of the safety incidents the ODI is investigating."
"The last time an NHTSA probe developed into an engineering analysis, it resulted in two waves of recalls and updates impacting nearly every vehicle Tesla had ever sold in the US up to that point."
The National Highway Traffic Safety Administration's Office of Defects Investigation is conducting an engineering analysis of Tesla's Full Self-Driving degradation detection system, which is designed to alert drivers when cameras cannot safely operate due to poor visibility. According to NHTSA filings, the system fails to detect and warn drivers appropriately during conditions like glare and airborne obscurants. In reviewed crashes, the system did not identify common roadway conditions impairing camera visibility or provide timely alerts before incidents occurred. Tesla began developing an update in 2024 following a fatal 2023 incident, but NHTSA lacks clarity on which vehicles received the update. This engineering analysis represents the second phase before a possible recall, following a similar 2024 investigation into crashes during poor visibility.
