Volvo Trucks North America is recalling some 2018-2020 VNL and VNX models because the sleeper bunk’s window may detach and fall from the vehicle. That could startle a following motorist and cause a crash.
Four percent of the 11,089 recalled trucks could have the issue, the National Highway Traffic Safety Administration said.
No accidents or injuries were reported by NHTSA.
The quality of the adhesion bond between the hinge and the glass, the size of the mechanical fasteners holding the window, and driving with the window open are being investigated to find the root cause, Volvo said.
Owners were cautioned against driving with the rear bunk window open until the window hinge has been replaced with a stronger hinge. Volvo will conduct the recall for free when parts are available.
The issue was reported to Volvo in September 2018. Volvo made a production change in January to improve the adhesive bonding between the window glass and hinge and began using a larger mechanical fastener.
The company told NHTSA in March that it would recall trucks built between Jan. 31, 2017, and Jan. 11, 2019. The NHTSA recall number is 19V-208.
