1996 Volvo ACL Problems, Complaints & Recalls

Problem: Vehicle description: class 8 heavy duty trucks. The air suspension control valve supply line was not plumbed through an air pressure protection valve. In the event of a failure, there would be loss of air pressure in the 'b' system air reservoir that supplies air pressure for the front steer axle brakes.

Risk: This condition would result in increased stopping distances.

Fix: Dealers will install the necessary air pressure protection valve.

Problem: The traction solenoid exhaust can be obstructed due to inadequate drainage and a build-up of road contamination between the mounting bracket and the solenoid housing. The obstructed exhaust prevents the relay valve control air pressure from venting after a differential braking traction event.

Risk: This condition would keep the rear axle service brakes applied without any brake pedal movement by the driver increasing the risk of a vehicle accident.

Fix: Dealers will remove the suspect valve and install a new valve that has a modified solenoid housing which will allow for sufficient drainage and a new valve mounting bracket with increased height to reduce entry of contamination.

Problem: Vehicle description: heavy duty class 8 vehicles built with a volvo 5.7 (12,500 lbs) front steering axle. Due to hydrogen embrittlement, the front steering axle king pins could have broken during assembly. Continued operation of a vehicle with a broken king pin could allow the pin to work loose.

Risk: This condition can cause erratic steering resulting in loss of steering control increasing the potential for a vehicle accident.

Fix: Dealers will inspect the vehicles for a broken king pin and replace the king pins if broken.
