There are 2 owner-reported driver assist & adas complaints for the 2019 Lexus NXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
In heavy rain situations I get an error message stating all front active safety systems (forward collision warning, etc.) do not work. The error states to clean or clear the front sensors of the vehicle. There is nothing blocking the sensors but in heavy weather these situations become much more important. Lexus states this is normal when heavy water situations come into play. I understand for going through flood waters but I don't believe it should be in heavy rain. I feel this is a major safety hazard that should come with warnings.
During heavy wind driven rain the front sensors start to show errors on the screen. These errors cause the the advance safety systems and parking sensors to deactivate. The warnings state to clean the sensors. Sometimes stopping the vehicle and turning off and on the ignition seems to resent but it does happen again. Usually this takes about 30 minutes of heavy rain to cause the. All other functions of the vehicle work but most safety systems appear to deactivate because of the sensors. This should not happen during a time when the systems are most needed.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
