What's wrong

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2015-2017 Isuzu NPR, Reach, 2016-2020 Isuzu NPR XD, NPR HD, NQR, 2016-2021 Isuzu NRR, 2017-2020 Chevrolet 4500XD, 4500HD, 5500HD, and 2020 Chevrolet 5500XD vehicles. The U-bolt nuts for the rear axle may not have been properly tightened and may loosen, causing the axle to misalign.

Isuzu will notify owners, and dealers will inspect and, if needed, replace and tighten the rear axle U-bolt nuts, free of charge. The recall began on April 23, 2021. Owners may contact Isuzu customer service at 1-866-441-9638. Isuzu's number for this recall is V2103.
