Technical Service Bulletin CB22-E-001A — 2018 ISUZU FTR

Isuzu Motors Limited has decided that a defect, which relates to motor vehicle safety, exists in 2018, 2019, 2020 and 2021 model year F-Series vehicles. The jam nut for the steering stopper bolt on the left side may loosen and allow the bolt to back away from the steering knuckle. This could result in an increase in the turning radius of the vehicle in left turns, which could make it difficult to make sharp turns. If the vehicle's turning radius is increased, there is an increased risk of a crash. A prior recall (19V-467) was conducted to address this issue, but we have identified this condition on vehicles that were remedied in that campaign as well as those that were produced after a change in production intended to prevent the condition.
