This concern occurs when the ambient temperature is within a certain range (approx. 16-25 C / 61-77 F). This is caused by the control software of the Dash-Electrical Supply Unit (Dash-ESU) not being appropriate for this specific situation. To correct this concern, the control software of the Dash-ESU has been modified.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10168071-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10168071-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10168071","components":[{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"hvac","name":"Heating and air conditioning","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"MAZDA3","year_from":2019,"year_to":2019,"match":"exact","vehicle_ids":["2019_mazda_mazda3"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
