Known issues on the 2021 Frontier. Two recalls are on federal record for this model year, and both trace back to the same automatic transmission fault: the transmission parking pawl may not engage when the vehicle is shifted into park, which can let the truck roll away and increase the risk of a crash. No complaints or technical service bulletins are logged for the year. The factory diagnostic and repair procedures behind the parking pawl and transmission linkage are here.
Whether you're inspecting the parking pawl after a rollaway concern or working through a scheduled service interval, it keeps you on the OEM procedure and the correct specification for your specific 2021 Frontier.
