Isuzu Technical Center of America is recalling 258 model year 2015-2017 Isuzu NPR, Reach, model year 2016-2020 Isuzu NPR XD, NPR HD, NQR, model year 2016-2021 Isuzu NRR, model year 2017-2020 Chevrolet 4500XD, 4500HD, 5500HD, and model year 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.
The misalignment may cause the propeller shaft to separate, causing a loss of power to the rear wheels and a stall, increasing the risk of a crash.
What to do
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 is expected to begin April 23, 2021.
Owners may contact Isuzu customer service at (866) 441-9638. Isuzu's number for this recall is V2103.
