Chrysler’s Ram Trucks division is voluntarily recalling nearly 2,000 Heavy Duty trucks over a miscalibrated top speed governor, which would allow the trucks to exceed the speed rating of the factory tires.

The recall covers 2014 and 2015 Ram 4500 and 5500 HD Chassis Cab trucks powered by the mighty 6.4-liter HEMI V-8 and equipped with dual rear wheels. An estimated 1,771 trucks are affected in the U.S. with another 169 trucks affected in Canada.

The issue surrounds the top speed governor, which was mistakenly calibrated for 106 mph. That exceeds the speed rating on the tires and could potentially lead to the premature failure of a tire.

“While FCA believes it is unlikely that these trucks are operated at such speeds, and that doing so would exceed posted speed limits in nearly every applicable jurisdiction, the Company is acting out of an abundance of caution,” the recall states.

Ram will offer free recalibrations of the governor to Ram customers, setting the truck’s top speed to 87 mph.

Why it Matters

Getting a full-sized Ram 5500 Chassis Cab truck up to 106 mph seems like a harrowing feat of dare-devilish foolery in the first place, but the thought of having a tire failure at those speeds is downright terrifying – especially considering how heavy the 4500 and 5500 trucks are.

This particular recall aside, it’s nice to see automakers fess up to mistakes like this and voluntarily work to fix them. This sort of practice is what will restore the public’s faith in automakers in these recall-heavy times.

On a side note, it’s humorous that FCA – the maker of the Hellcat, Viper, and all things SRT – would make a statement about how 106 mph would “exceed posted speed limits in nearly every applicable jurisdiction.” I guess they figure all those high-horsepower owners are responsibly hooning at their local track.

Statement: Speed Recalibration

May 15, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 1,771 trucks in the U.S. to recalibrate their maximum speed.

The dual-wheel trucks are currently restricted to a top speed of 106 miles per hour (mph), but an internal specification review revealed top speed should be set at 87 mph, in accordance with their factory-equipped tires.

The Company is unaware of any related injuries, accidents or customer complaints.

Dealers will recalibrate vehicle speed accordingly. While FCA believes it is unlikely that these trucks are operated at such speeds, and that doing so would exceed posted speed limits in nearly every applicable jurisdiction, the Company is acting out of an abundance of caution.

The campaign is limited to certain model-year 2014-15 Ram 4500/5500 Chassis Cabs equipped with 6.4-liter HEMI V-8 engines. An additional 169 vehicles are believed to be in Canada.

Affected customers will be advised when they may schedule service. Customers with questions may call the FCA US Customer Information Center at 1-800-853-1403.
