GMC Canyon repeated dead battery issue with multiple recharges since October 2020 on GMC Canyon

Some GMC Canyon owners report experiencing repeated dead battery issues, often requiring multiple recharges since October 2020. The primary cause of these dead batteries is internal degradation due to age, with most batteries lasting only 3 to 5 years. Additionally, owners have noted that if the truck is left sitting for more than 10-12 days, the battery tends to die. In some instances, GM has issued service bulletins to address battery drain issues, including a specific bulletin for the 2024 GMC Canyon related to problems with the over-the-air software update system. Furthermore, some owners have encountered unexplained battery failures, necessitating jump-starts. It is crucial for owners to address any battery draining issues promptly, as a dead battery can occur even when the vehicle is not in use, indicating a potentially serious underlying problem.
