What's wrong: The electric current rectifying module contained within the dc-dc converter may have been damaged during production, which can result in an electrical short-circuit.
Why it matters: A short circuit can cause the dc-dc converter to overheat, increasing the risk of a vehicle fire.
The fix: Owners are advised not to charge their vehicles when the ambient air temperature is below or expected to drop below 41 degrees fahrenheit (5 degrees celsius). Dealers will replace the dc-dc converter, free of charge. Owner notification letters were mailed December 29, 2023.
