Full-size trucks have technology problems too, and Ram just found that out the hard way. Stellantis announced the withdrawal of more than 12,000 units of the Ram 2500 after detecting a failure related to the electronic calibration of the vehicle’s maximum speed.

At first glance it may seem like a minor detail, but the problem has important implications for security. According to the information presented to the US authorities, certain units could exceed the maximum speed for which their original tires were approved.

The campaign specifically affects Ram 2500 models manufactured between June 2022 and April 2026. In total, the recall involves 12,736 trucks sold in the United States.
The problem is not in the tires
One of the points that Stellantis most wanted to clarify has to do with the origin of the failure. The tires have no physical defects or manufacturing problems. The problem appears due to incorrect programming within the vehicle’s electronic system.
Some units received the wrong calibration in the software that controls maximum speed. That would allow the truck to exceed the safe limit associated with the speed rating of the factory-installed tires.
In this case, many of the affected Rams use “R” rated tires, prepared to withstand speeds close to 106 miles per hour. If the vehicle exceeds this figure for a prolonged period, the tire may work outside the expected safety parameters.
What risks can this failure generate?
When a tire operates above its approved limit, significant risks begin to appear. Excessive speed can cause excessive temperature rise, accelerated wear and even structural damage.
In more extreme scenarios there is also the possibility of layer separation or internal failures that could end in a blowout.
Precisely for this reason Stellantis decided to move forward with the preventive withdrawal before major incidents appear. The company assured that so far there are no reports of accidents or claims directly related to this problem.
The solution will be simple and free
The internal investigation officially began on March 24, 2026 through the Technical Security and Regulatory Compliance division of FCA US. After several technical reviews, the group approved the voluntary withdrawal on April 30.
Unlike other much more complex campaigns, this time it will not be necessary to replace mechanical parts or change tires. The solution will simply consist of a software update.
Dealers will reprogram the Powertrain Management Module, known as PCM, to correct the electronic speed calibration and prevent the truck from exceeding the safe limit of the installed tires.
Stellantis will begin informing dealers in mid-May, while the owners will receive official notifications from June 4, 2026.
The repair will be completely free and aims to resolve the problem in a short time.
