What Are 2019 International LT Problems

In recent years, Navistar has issued a recall of thousands of International trucks. According to the company, this recall was made because of some issues linked with the engine stalling.

As an example, the 2019 up to 2021 models of the International LT, as well as the RH trucks have been recalled. Over 10,000 of these trucks were noted to have some problems with the engine. In fact, the National Highway Traffic Safety Administration has released a report that the wrist pin located in the engine has a tendency to crack over time. This can result in the connecting rod failing, which can increase the possibility of a crash.

Because of this huge safety risk, Navistar recalled these trucks to prevent serious safety issues. Dealers were also required to install in their fleet a detection system software that helps to warn drivers before an engine connecting rod failure occurs. Moreover, engines that are proven to possess a defective connecting rod are going to be repaired.

Furthermore, there was another recall made in early 2020 by Navistar. This involves International LT and RH trucks with the model year from 2018 to 2020. Affected owners of these trucks were notified, so this can help facilitate the inspection and any repairs needed to the problematic components linked with safety concerns.

Common Issues With the 2019 International LT Trucks

Generally, the 2019 International LT truck is reliable and with a robust engine. However, there were some complaints about this truck such as wiring failures and electrical problems. There were also a few concerns with the high pressure oil lines and transmission issues. 

Moreover, the increased concerns with pumps failing and leaking, poor service records and camshaft malfunction are added to the list of common issues with the truck. 

There are also some other common repair issues regardless of the size of the truck by International. This is why it can be quite costly to maintain and ensure the performance of the vehicle over time. 

Generally, wiring and electrical failures originate in various areas including the fuel and cab control systems and emissions. When these problems arise, the trucks are rendered inoperable unless the issues are resolved first.

When there is a high pressure in the oil system, this can lead to injector failures, which also result in engine-related problems. To add to all of these, there are poor service records from International truck dealers, which does not help the situation. Hence, vehicle downtime becomes prolonged and there are complex repair processes involved along the way.

Other Concerns With The 2019 International LT

Aside from the issues mentioned above, there were a few other complaints with this truck. For instance, the doors tend to unlock when the air brakes are pulled. Some people also get confused about the auto climate function and how to operate it. This system appears to be temperamental and some would manually adjust it, only to find that it goes back to failing to cool down or heat up the interior of the vehicle. 

However, one thing you can look into is by programming out the door locking function. It can also help to ask a specialist for the adjustment needed in the HVAC function since it does get quite confusing for many folks.

Bottom Line

Problems with the International LT often start with the battery cable, which can break. When this happens, a loss of electrical power and engine shut down occur. It is due to the cable not being capable of withstanding the stress placed by the truck’s movement. Moreover, it is a design error that makes it happen.

Once the truck experiences a power loss, this can lead to a safety hazard because of a potential crash. This is why several thousands of International LT trucks have been recalled, including the 2019 model year to have this issue looked into and fixed. 

Dealers are tasked to replace this problematic battery cable with a sturdier and more flexible material, so it will not break while the truck is in motion. Hence, this should prevent potential issues that can lead to major inconveniences and accidents.
