Big trucks also have technological problems and Ram just proved it in the worst way. Stellantis announced the retirement of m more than 12,000 units of the Ram 2500 after detecting a fault related to the electronic calibration of the vehicle's maximum speed.

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

The campaign specificallyaffects Ram 2500 models manufactured between June 2022 and April 2026. In total, the recall involves 12,736 trucks marketed in the United States.

The problem is not in the tyres

One of the points that Stellantis wanted to clarify has to do with the origin of the failure. The tyres do not present physical defects nor manufacturing problems. The inconvenience appears due to incorrect programming within the vehicle's electronic system.

Some units received a wrong calibration in the software that controls the top speed. That would allow the truck to exceed the safe limit associated with the speed rating of the factory-installed tires.

In this case, a large part of the affected Ram uses “R”-rated tyres, prepared to withstand speeds close to 106 mil the per hour. If the vehicle exceeds that figure on a prolonged basis, the tire can work outside the predicted safety parameters.

What risks can this fault generate?

When a tire operates above its approved limit, significant risks begin to appear. Excessive speed can cause an excessive temperature increase, 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 Stellantis decided to move forward with the preventive recall before major incidents appear. The company assured that so far there are no reports of accidents nor claims related directly to this problem.

The solution will be simple and free

The internal investigation officially started on 24 March 2026 through the Technical Security and Compliance division regulatory liance of FCA US. After several technical reviews, the group approved the voluntary withdrawal on 30 April.

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 Control 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 owners will receive official notifications from June 4,2026.

The repair will be completely free and aims to solve the problem in a short time.
