What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 96 complaints with NHTSA since 2015. 47 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The 2026 RHO is pulling to the right every time you accelerate the gas pedal. I took in to the Dodge dealership to check it out. They did an alignment check and adjusted. Went on a test drive with the mechanic and did a drive on street and highway. The mechanic noticed the vehicle pulling to right.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ram 08-149-26 REV. A a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the 08-149-26 REV. A repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does 08-149-26 REV. A cover?
The manufacturer filed it against 1 model year: 2026 Ram 1500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
