2026 VOLVO VNL (4) Safety Overview

Component: SERVICE BRAKES,BACK OVER PREVENTION

"I am submitting this complaint to report a serious safety issue involving a Volvo VNL truck. The vehicle was purchased new on December 12, 2025 and currently has approximately 22,000 miles. Since shortly after purchase, the truck has experienced a defect in the braking system. While driving, the vehicle has unexpectedly applied the brakes on its own and has displayed warning messages related to the parking brake system. This creates a dangerous situation because sudden braking can cause loss of control or lead to a collision with other vehicles. The truck was taken to an authorized Volvo dealer for repair and remained at the dealership for approximately one month while technicians attempted to diagnose and repair the problem. After the truck was returned to me, the exact same issue occurred again almost immediately. Because the braking system is a critical safety component, the unexpected application of brakes while driving presents a serious risk to the driver and to other motorists on the road. The defect has persisted despite extended repair attempts. I am reporting this issue so that it can be investigated as a potential safety defect affecting this vehicle model. Vehicle Information: Make: Volvo Trucks Model: VNL Purchase Date: December 12, 2025 Mileage: Approximately 22,000 miles I request that this safety issue be reviewed and investigated to determine whether other vehicles may be affected by the same defect."

"The contact owns a 2026 Volvo VNL(4). The contact stated that while driving approximately 75 MPH, the message "Stop Vehicle - Apply Parking Brake Only While at Stand Still" was displayed, with three unknown warning lights were illuminated, with a continuous audible alert. The vehicle was taken to a dealer, where a diagnostic machine was connected, but the computer system crashed. The cluster display, environment control, gateway, radio and entertainment, driver control, and telematic gateway modules, and the CCIOM, RIOCM, VMCU, SCIM, and DACU, all needed to be replaced. The vehicle was repaired, but the failure reoccurred two and a half hours later. The vehicle was taken to another dealer, however, before the vehicle was diagnosed, it turned off in the parking lot with the doors wide open and the key not in the ignition. With the battery saver mode activated, the vehicle rolled forward inadvertently. The contact's husband was in the bed of the vehicle and reached into the front of the vehicle and pulled the air brake, however, the vehicle failed to slow down. The brake pedal was depressed, and the vehicle stopped. The vehicle was diagnosed, and the contact was informed that the wheel speed sensor needed to be replaced. The vehicle was repaired. On another occasion, while attempting to park the vehicle with the parking brake activated, the parking brake failed to engage, and the vehicle rolled forward. The vehicle was taken to a dealer, where the failure could not be duplicated; however, the EBS module was replaced. The vehicle was repaired, but the failure recurred intermittently. The vehicle was taken to another dealer; however, the failure was not duplicated. The contact stated that the engineers diagnosed the vehicle and determined that the two axles might need to be replaced. The manufacturer was notified of the failure. The failure mileage was 54,000."
