2024 FREIGHTLINER CASCADIA

ELECTRONIC STABILITY CONTROL (ESC)

Daimler Trucks North America, LLC (DTNA) is recalling certain short wheelbase 2020-2024 Freightliner Cascadia, 2021-2024 Freightliner M2 Business Class, 2022 Western Star 4700, and 2020 Freightliner Classic Cascadia vehicles. The vehicle is equipped with an electronic stability control system and t

STEERING

Daimler Trucks North America, LLC (DTNA) is recalling certain 2024 FCCC MT45G, MT45, and Freightliner Cascadia vehicles. The steering gear assemblies may have been assembled incorrectly with fewer recirculating balls than are required, which may result in a loss of steering control.

The forward collision avoidance system fails to distinguish stationary objects from animate objects resulting in immediate engagement of the braking system.

See attached document for complaint.

The cruise control (level 2 autonomous) will turn itself off without any warning sometimes. This happens any time the truck is set for above the speed limit by more than 2 mph. The truck uses a speed limit map, independent of actual posted speed limits. When the truck detects a speed limit drop to below the cruise setting, either real or imagined, the cruise control disengages without any warning or notification. This is a problem when I expect the truck to continue its autonomous function i

When approaching stopped traffic, sometimes the truck will respond and begin to slow down. At other times, the truck will continue at set speed toward a detected stopped vehicle, and in situations where the time and distance are way too short to justify no reaction by the system. The truck at sometimes acts like it is auto-driving; at others it acts as if it is only in crash-mitigation mode, and will wait for the driver until the last possible second and then slam on brakes.

When driving in highway traffic at moderate to high speeds (as well as low speeds), the truck will often accelerate with (and towards) a vehicle that is less than 1 second ahead of the truck. Certainly this often happens when there is not a safe distance between the truck and the next vehicle. The trucks systems in no way seem to expect that the next vehicle could slam on brakes at any moment. I have had this happen many times when a vehicle merges too close in front of me and then accelerate

When a vehicle is merging into my lane, the truck will often not detect or react to the encroaching vehicle; this happens even when there is plenty of space, and the encroaching vehicle is halfway into my lane. I have had to intervene several times, since the truck was accelerating toward the previous vehicle in my headway, and ingoring the intervening merging vehicle. In contrast, the sensors in the truck apparently can see when a vehicle is near to the front, and mostly out of the headwa

These trucks have a non-adjustable default setting for Over and Under cruise control speed setting. This means, in the case of the truck I drove, that the cruise control will allow the truck to go 5 mph over the set speed before engaging the engine brake, or 4 mph under the setting before accelerating. The problem is that when set for the speed limit, the truck will climb to 7 mph over the set speed before engaging engine brake. When driving on a downgrade with a lot of weight, the truck quic

Complaint 1 When using cruise control in 2024 Freightliner Cascadia trucks with level 2 autonomous driving features, there is no option to turn off the autonomous driving features (and use standard cruise control); the driver is forced to use the system if he wants or needs to use cruise control. This apparently is a software setting that is available in some versions, but is not available in models bought/leased to large trucking companies.

The cruise control has been programmed to stay engaged, in many instances, after the driver has used the foot brake. In some situations, like approaching a traffic circle, I have slowed down with the foot brake, then had the truck unexpectedly start to accelerate after I released the brake. This apparently has to do with a vehicle in my headway allowing the cruise to remain engaged, and then after the vehicle leaves my headway the truck thinks it can accelerate again.
