Owners have filed 11 complaints with NHTSA about the 2026 Frontier. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 1 recall campaign for the 2026 Frontier over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Nissan North America, Inc. (Nissan) is recalling certain 2025 Altima, Sentra, 2025-2026 Frontier, and 2026 Kicks vehicles. The door strikers may have been improperly welded and break, allowing the door to open while moving. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 206, "Door Locks and Door Retention Components."
Risk: A door that opens unexpectedly while the vehicle is in motion increases the risk of injury or a crash.
Remedy: Dealers will replace the door strikers, free of charge. Owner notification letters were mailed March 17, 2026. Owners may contact Nissan's customer service at 800-647-7261. Nissan's numbers for this recall are PD185 and PMA61. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning January 28, 2026.
