If you’re one of the 1,771 owners of a 2014-15 Ram 4500 or 5500 chassis cab with a 6.4-liter Hemi V8 and a dualie rear axle, you may be hearing soon from Fiat Chrysler Automobiles to bring your truck in to your local dealer.

The reason, you ask? To have the speed limiter recalibrated. The problem, according to the statement below, is that while some of these trucks are electronically limited to 106 miles per hour, their tires can’t safely maintain that speed. As a result, FCA is having dealers recalibrate the limiter to 87 mph.

Of course, that’s still well above the speed limit in most places, and “FCA believes it is unlikely that these trucks are operated at such speeds,” but that it “is acting out of an abundance of caution.” In addition to the 1,771 units in the United States, the company is recalling another 169 in Canada.

In an unrelated campaign, FCA is also recalling a handful or two of 2015 Dodge Challengers – 72 in the US, six in Canada and three in Mexico – to secure a side-curtain airbag bolt that may have been improperly installed during assembly over the course of a ten-day period.

In both cases, FCA says it is unaware of any complaints, accidents or injuries related to these issues.
