NHTSA has issued service bulletins regarding Lexus servo motor issues, primarily affecting the HVAC system, because these motors can have internal electrical malfunctions. This malfunction can cause symptoms like uneven or inconsistent air temperature from the vents, lack of airflow from selected vents, improper mode control, and the storage of Diagnostic Trouble Codes (DTCs) related to the damper control servos. This is an issue because it affects Safety and Convenience due to the following: While these issues primarily affect comfort and convenience by disrupting the climate control system, a malfunction of other servo motors (which control things like air flow direction or even steering in other situations) could create a safety risk. Experiencing this in my 2015 NX 200t today made me feel unsafe, as the vents were blowing out extremely hot air. And during hot Texas weather that is unsafe, and I have children that I have in the car with me at times. The Lexus dealership in Grapevine Texas is asking for $2,600+ to fix servo motor 1 and 2 after they ran diagnostics. It seems as if a vehicle that was in the same year and is experiencing the same exact issue as other vehicles in that year should also be covered as those that got it fixed under Lexus’ warranty. What makes the NX model different from the 6+ other models that Lexus a covered under the NHTSA safety bulletin/ recall?
