There are 1 owner-reported engine complaints for the 2019 Nissan Frontierin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
We have three 2019 Nissan Frontier pickups in our fleet that have all recently had the same problem. A engine valve misfire on cylinder 3 on all three trucks. This has caused the trucks to shake, idle rough, and have loss of power while driving. Two independent mechanics have inspected the trucks and have replaced multiple parts to try and fix the problem, however, it has been recommended that all three trucks have the engine replaced. The check engine light did activate on the dash when the problem first began in each truck.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
