Owner Complaints for the 2020 INTERNATIONAL LT

4 complaints have been filed with NHTSA for the 2020 INTERNATIONAL LT. Below is a breakdown by vehicle component.

Most Recent Complaints

#11524828 | FORWARD COLLISION AVOIDANCE | | 290,000 miles
The contact owns a 2020 International LT625 Truck. The contact stated that while driving at an undisclosed speed, the vehicle experienced unintended braking. The contact stated that the Forward Collision Avoidance warning light illuminated; however, the contact stated there was no object nearby or in the roadway. The vehicle was taken to the dealer, where Forward Collision Avoidance sensors were recalibrated; however, the failure recurred. The manufacturer was made aware of the failure. The failure mileage was approximately 290,000.
#11449287 | ENGINE AND ENGINE COOLING:ENGINE:DIESEL | | N/A miles
related complaint tracking number: 11442614 The engine crankcase ventilation pours large volumes of exhaust gases and oil vapors into the engine bay of the truck. This is a design flaw. The crankcase exhaust exits to the inside of the frame, at the front left of the engine, approximately central vertically under the hood. This continually fills the engine bay with exhaust gases and vapors. There is an attached video and pictures. A separate email will be sent to add this information to 11442614. Since the original complaint is related to the exhaust gases coming into the cab, and this one is about an actual flaw in the exhaust system allowing the venting of gases under the hood, it seemed to me that it would end up being a separate recall issue, even though directly related. Here is a link to thermal videos of the link on Onedrive: https://1drv.ms/u/s!ApLkoRLyIsQVjlZpQq2cwOL7nHLP?e=OdSRyA If the video appears garbled, move the play slider back to the beginning and it should play correctly. The videos appear to have no problem on mobile devices. The picture with the colored boxes gives a 3 point approximation of the location of the leak; directly down from blue box, directly behind green box, and directly lateral to the yellow box. Other pics are of crankcase vent opening and its location on most Cummins engine equipped trucks.
