Overview

2021 Nissan Frontier

The 2021 Nissan Frontier enters the used market as a practical, if somewhat dated, mid-size truck. Powered by a standard 3.8-liter V6 engine paired with a 9-speed automatic transmission, it delivers respectable performance for towing and hauling. Its part-time 4-wheel drive system enhances capability in adverse conditions. While the Frontier boasts a strong public reliability score, the LLM assessment points to an average rating, primarily due to transmission-related recalls. Fuel economy is competitive for its class.

Critical Failure Risk

A critical safety recall addresses the potential for the transmission parking pawl to fail to engage, which can lead to the vehicle rolling away. This can be caused by software issues or component wear within the transmission.

Early detection can help you avoid a $500-$1,500 repair.
