General Motors has started a customer satisfaction program to address an issue with the 2021 model-year Chevy Traverse crossover that can cause phantom drain in the battery.
The problem: affected vehicles may have radio modules that were shipped to the GM Lansing Delta Township plant switched to “DEV Mode.” A radio that has been switched to “DEV Mode” will remain powered on even when the main vehicle power has been switched off, causing the battery to drain.
The hazards: while this problem does not pose an immediate safety risk to the driver or vehicle occupants, the phantom drain scenario may leave drivers without vehicle power.
The fix: dealers are instructed to turn the vehicle on and inspect for words reading “DEV Mode” on the vehicle display. If the vehicle radio is in fact in “DEV Mode,” the technician will replace the existing radio with a new one and will reprogram the new radio. All involved vehicles that are in dealership inventory must be held and not delivered to customers, deal traded or used for demonstration purposes until the repair described here has been performed. This customer satisfaction program will remain in effect until June 30th, 2023.
Affected components: infotainment system.
Number of affected vehicles: GM has not yet announced how many crossovers are affected by this particular issue.
Owners should: GM will notify owners of affected vehicles and instruct them to make an appointment with their dealer. Owners of affected vehicles with questions or concerns can also reach out to Chevrolet directly using the contact information included below.
