Odometer Fraud. The contact sold a 2021 International LT625. The contact stated that he was a car dealer who had sold the vehicle and several other vehicles to a fleet dealer. The vehicles were a dealer sale. At the time of sale, the vehicles had approximately 600,000 miles; however, the fleet dealer currently listed the vehicle and the other vehicles for sale, showing 300,000 miles. The contact confirmed through VINs and pictures posted on the fleet dealer's website and Facebook Marketplace that the listed vehicles were the exact same vehicles the fleet dealer had purchased from the contact.

The brake assist malfunctioned causing the brakes to abruptly stop without cause or warning. When the braking system abruptly stopped it caused a jack knife and lost of a trailer on a congested highway with vehicles in all lanes, I was able to finally get control of the tractor with out causing contact or injury with other vehicles and the rear trailer broke free and rolled back and landed in the grass that divided the highways. I injured myself and had to have surgery. The tractor was taken to a shop 4 days after the accident. They found that the module for abs ec80 had blocked radar and data link faults for camera, radar & camera was not properly installed. Rush truck center told the company that they needed to drive tractor on a long drive to recreate issues, but the company denied to go forward and picked the tractor up.

I drive tractor trailer for JB Hunt. Over the last 4 Years, the three trucks I have been assigned to have had exhaust leaks that vented into the cab. One was a Freightliner (approx 2017 model), and two have been Internationals. These exhaust leaks caused me medical problems, requiring that I take off time unscheduled. The last three trucks I have been assigned to have had exhaust leaks into the cab. Some leaks I only found with a thermal camera. The exhaust leaks are not the main problem. The problem is that design of these trucks cause any leaking engine gases to be pushed into the cab of the truck, mostly through the air conditioning/heater vents. I have tested this. I zip tied a can of orange air freshener under the hood. The can was positioned in such a way as to point away from the air intake box, toward the back of the engine. When driving at highway speed, the orange air freshener was very strong coming into the cab from the a/c vents. The truck is supposed to be getting the fresh air from outside the truck, and forward of where the air freshener was spraying. I originally thought the only problem was that the cabin air intake box is located under the hood, in immediate proximity to all of the leaks. This in itself is a poor design. Even with duct tape over the openings into the cabin air box, any gases (or air freshener) is immediately pulled into the cab through the a/c and heat. I have no idea how this occurs. The design of the trucks allows any leaking gases under the hood to come directly into the cab. This applies to Freightliners and Internationals. They have the same basic design, and by experience I can say that both perform the same way. The hoods on both truck makes are designed with dedicated pathways to provide pure outside air for the intake of the ENGINE. The air provided to the driver comes from an unsealed airbox located under the hood. The main problem is not the leaks but that they get vented into the driver's cabin. The engine crankcase ventilation pours large volume

POWER TRAIN
Feature code 0008TSJ for auto start stop is a feature that will allow you to preset values in the body controller to allow the truck to start when the battery voltage or engine oil temperature reaches the preset value. The engine will then run for a preset time after battery voltage is within programmed value (if the engine started for low voltage) or the engine will run until oil temperature reaches a programmed value (if the engine started for oil temperature).
ENGINE
Effective January 1, 2008 , engines built for vehicles registered in California or a CARB (Air Resources Board of California) opt-in state must be emission certified under the new California Idle Reduction Rule (CCR Title 13 Section 1956.8(a)(6)). A CARB opt-in state is any state other than California that requires CARB emission certified engines. The new ruling states that new diesel-powered vehicles with a GVWR greater than 14,000 lbs and a MY2008 or later engine that are initially registered in California must have a tamper-proof engine shutdown system (ESS) or a low NOx idle main engine unless it is a vocationally exempted vehicle.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Complaint and recall counts across every year of this model
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
