Daimler Truck Actros 963 recalls

Through a self-disclosure by the supplier ZF Friedrichshafen AG Daimler Truck AG was informed that there may have been a manufacturing deviation in vehicles of the models Atego 967 Actros 963 Arocs 964 and eActros 983 on the ball joints that are installed in steering components (e. g. drag links steering links tie rods). It cannot be ruled out that individual components did not fully undergo the prescribed hardening process and have therefore gotten into vehicles with insufficient material hardness. This may result in increased wear and in later phases reduced fatigue strength to the point of a possible fatigue fracture which would probably occur at low speeds with high steering forces (e.g. when maneuvering). In the event of such a fracture vehicle can no longer be steered and there would be a risk of accident.

Fix: As part of our planned recall campaign and as a precautionary measure we want to check whether insufficiently hardened components were installed in the potentially affected vehicles. Insufficiently hardened components will be replaced as part of the check.

As part of our continuous quality monitoring we have identified that in Actros 963 Arocs 964 vehicles with integral rear area and eActros 300/400 with fleece battery (absorbent glass mat) a thermal reaction may occur due to corrosion on the ACE chip (Advanced Connected Energy). Battery data can be evaluated via a Bluetooth interface using the integrated ACE chip. During assembly of the ACE chip at the supplier’s premises it is inserted into the recess provided between the battery terminals poured with resin (liquid plastic) and closed with the battery cover to protect against corrosion in a fully automated and quantity-controlled process. When filling with resin there may have been an insufficient fill level in the niche as well as an ACE chip inserted at an angle. The exposed connection points of the supply lines or the chip itself may corrode due to inadequate sealing. A corroded connection or corroded ACE chip may lead to increased electrical transitional resistance which may trigger a thermal reaction leading to a battery fire. In the worst case flames may spread to surrounding components or the vehicle. There is a risk of fire.

Fix: Check printed circuit board in on-board electrical system battery for damage. Replace on-board electrical system battery (after check) if necessary.

At Mercedes-Benz we constantly monitor our products to ensure the highest quality and safety. The tyre supplier Michelin notified Daimler Truck AG as part of a voluntary declaration that a circumferential crack in the tyre sidewall may occur on your vehicle with 355/50 R 22.5 Michelin X MULTI Z and X LINE ENERGY Z type truck tyres. Vehicles that have been equipped with potentially affected Michelin tyres should therefore be checked.

Fix: As part of our planned recall campaign we will check the tires on potentially affected vehicles as a precautionary measure. Affected tires are then directly reported to Michelin and replaced.

As part of our ongoing quality monitoring we have determined that on Actros 963 and eActros 983 vehicles the rear wheel arch cover on the front axle could fall off. A design-related plastic rib that is too high leads to a collision between the wheel arch cover and the fender. Due to the excessively high plastic rib on the rear wheel arch cover of the front axle this may be installed with preload and thus some fastening points may not be fully engaged. As a consequence the engaged fastening points of the wheel arch cover may fracture and the wheel arch cover (931 mm x 652 mm x 70 mm approx. 1.81 kg) may completely detach from the vehicle and fall off due to the dynamic load during driving operation. This may increase the risk of accidents for other road users.

Fix: As part of the recall campaign the excessively high plastic rib must be shortened on the potentially affected vehicles.

The rear wheel arch panel of the wheel arch cover on the front axle may not be fully engaged on Actros 963 vehicles. Due to incorrectly executed geometry by the supplier three out of five clips of the wheel arch panel could come loose. As a consequence the remaining correctly executed mounting clips and the lower screw point may fail and the wheel arch panel may detach completely from the vehicle and fall off. This may increase the risk of an accident for the following traffic.

Fix: As part of the recall campaign the wheel arch panels must be replaced on the potentially affected vehicles.

Actros 963 and Arocs 964 models depending on the model designation up to two screws per installed axle bearing bracket may be missing. The axle bearing bracket guides the rear axle in the longitudinal direction of the vehicle. Spontaneous failure of the threaded connection can be ruled out. According to the Development department’s assessment loosening of the installed screws is possible at the earliest after approx. 600000 km.

Fix: As part of the recall action it must be checked whether all specified threaded connections are present on the axle bearing brackets on the potentially affected vehicles. If not the missing threaded connections must be retrofitted and tightened to the specified torque.

The retrofitted DVS camera / sensor wiring harness along the chassis/cab frame may have been carried out incorrectly. As a result of an incorrectly installed DVS retrofitting scorching damage could occur in the area of the transition from the frame to the cab (swan neck) due to chafing of the wires. Depending on the nature of the damage / or level of chafing the possibility of a vehicle fire cannot be ruled out.

Fix: As part of the planned field measure we will check the DVS retrofit was carried out on behalf of DTUK as to whether the retrofitting of the cables was carried out in accordance with the specifications in WIS and the Bodybuilder Guideline and therefore if the chassis/cab frame wiring harness is still routed correctly.
