2026 Ram 1500 RHO Software Glitch Limits Top Speed

In recent weeks, a number of Ram 1500 RHO owners have been reporting a significant drop in their trucks’ top speeds, from the advertised 118 mph (190 km/h) to just 98 mph (158 km/h). With these complaints surfacing across forums and YouTube videos, many were left wondering if Ram had intentionally limited the truck’s top speed via a software update. To get to the bottom of this issue, we reached out to the Ram engineering team for clarification.

What Happened? – 

It turns out the issue was not intentional. Ram clarified that approximately 129 North American 2026 Ram 1500 RHO trucks were inadvertently flashed with a software update intended for export models. This occurred during routine dealer servicing and resulted in the truck’s top speed being limited to 98 mph—well below the originally advertised 118 mph (190 km/h) for the North American market.

Is This an Official Change? –

No, this was not an official change. The software update, which applied the lower top speed limiter, was an unintended error. Ram confirmed that this issue only affected a small number of vehicles and was not part of any planned update. The company has already addressed the problem and is taking steps to revert the changes.

What’s Being Done? – 

Stellantis, the parent company of Ram, is rolling out a rapid service update (RSU) to affected owners. The update will restore the top speed to its original 118 mph (190 km/h) specification. Expert technicians will visit affected customers to perform the update at their convenience, ensuring a smooth and efficient process. Stellantis is committed to contacting all affected owners directly to arrange the service.

Will This Affect Future Ram 1500 RHO Models? –

No, the 2026 Ram 1500 RHO will continue to have a top speed of 118 mph. Ram assured us that the issue was a one-off glitch that does not apply to future models or any other Ram 1500 RHOs moving forward.

Customer Communication and Support –

To make up for the inconvenience, Stellantis will also offer a complimentary oil change at participating dealerships. This is part of their commitment to customer satisfaction and quality. Affected owners will be contacted directly to schedule the RSU and to address any questions or concerns.

Stellantis is also conducting a thorough review to prevent similar errors in the future. They’ve emphasized that this was an isolated incident, and the correct engine software will be restored to all affected trucks.

Thoughts – 

While this situation may have caused some concern among Ram 1500 RHO owners, it’s clear that the issue was not intentional and is already being addressed. The 118 mph top speed will be restored to affected vehicles through the RSU, and future models won’t experience this issue.

As a reminder, Stellantis encourages all drivers always to obey posted speed limits and to drive responsibly. This minor glitch serves as a reminder of the complexities involved in modern vehicle software and the importance of careful quality control.
