NHTSA campaign 19V467000
Hazard
Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2018-2020 FTR and Chevrolet 6500XD vehicles. The jam nut for the steering stopper bolt on the left front knuckle may loosen and allow the bolt to back away from the steering knuckle, increasing the turning radius of the vehicle in a left turn.
Consequence
If the vehicle's turning radius is increased, there is an increased risk of a crash.
Remedy
Isuzu will notify owners, and dealers will replace the existing left and right jam nuts with a Grade 8 jam nut, torque the nut to a new torque specification and apply Loctite to the nut and bolt, free of charge. The recall began July 19, 2019. Owners may contact Isuzu customer service at 1-866-441-9638, GM owners may contact GM customer service at 1-800-862-4389. Isuzu's number for this recall is V1902.
