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.

my 2021 canyon truck battery died in garage with 44 miles on odameter, had truck towed to dealer. no repair jumped battery and told to drive truck more each and every day.
Unless you only drive 1/4 mile every other day, that sure doesn’t seem like a ‘responsive fix’ from GM.
Guess its time to run an extension cord to a $10 ‘battery minder’ trickle charger that you can hook up to the battery..
My new 2019 Canyon Denali’s battery was DOD (dead on delivery). Dealer gave me a boost the day I picked it up… Drove the vehicle some that day with no starting issues. Next day, vehicle wouldn’t start, I was livid… Phoned the dealer who told me to call GM Roadside. CAA shows up and gives me a boost. Drove the vehicle to the dealer who ‘tested’ the battery and found no issues. Ya right, no issues. I demanded and got a new battery. I looked at the vehicle’s manufacture date sticker on the door jam and realized the vehicle had been sitting on the lot for 8 months! First in first out I guess. So the battery was ruined because of not being charged for the 8 months, but no issues right?
On a positive note, the truck’s been great the past 2 years. Just the odd infotainment glitch like temporary loss of backup camera video, and having to periodically reinsert the memory card holding map data (to reestablish contact).
The dealer was supposed to hook up the battery analyzer immediately before delivery and document battery health and charge, for this reason exactly.
The dealer didn’t want to do anything because GM won’t pay warranty claims on this because of their negligence. You should have complained to GM directly because the dealer will then get a chargeback for the PDI they didn’t do.
If you all signed a lease or wanted to purchase the suv, DIDN’T KNOW of this problem beforehand; then it’s the manufacturers fault!
How much is the midnight black Chevy traverse
