There is a possibility that a stuck open thermostat may wrongly be detected causing the check engine Malfunction Indicator Lamp (‘MIL’) to illuminate. MBUSA will conduct an Emission Service Campaign. An authorized Mercedes-Benz dealer will perform a software update to the air conditioning control unit on the affected vehicles.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10238437-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10238437-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10238437","components":[{"id":"electrical","name":"Electrical
