A small number of customers may experience a slight spark knock condition during aggressive high speed driving. They may state that when this occurs, the vehicle is unable to achieve maximum top speed. No Diagnostic Trouble Codes (DTCs) are associated with this condition. In addition, customers may also comment that, with the cluster set on metric units, they are unable to accurately increase or decrease the cruise control set speed using the resume or set buttons. Instead of changing vehicle speed by 1 KPH when pressing the buttons, the vehicle speed will increase approximately 1.6 KPH.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2015/MC-10144864-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2015/MC-10144864-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10144864","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null},{"id":"automatic-transmission","name":"Automatic transmission","parent":"powertrain"},{"id":"transmission-control-module","name":"Transmission control module","parent":"powertrain"}],"codes":[],"topics":[],"vehicles":[{"make":"DODGE","model":"CHALLENGER","year_from":2015,"year_to":2015,"match":"exact","vehicle_ids":["2015_dodge_challenger"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
