Ram bulletin S2308000108

What it saysThe technician and owner would like to add a tire pressure monitoring system to a cab chassis vehicle. NHTSA’s full summary ↓

Ram filed this with NHTSA as a service bulletin dated Aug 26, 2023, received Oct 2, 2023, about the tires. It names 3 model years (2023). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Nexen Roadian HTX RH5 LT235/80R17E 120R/117/R At approximately 70 mph, I experienced a severe vibration in the steering wheel. Shortly thereafter, the tread separated from the carcass sending pieces of rubber flying. I was able to pull onto the shoulder and change the tire. These are the OEM tires with about 25000 miles.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Ram S2308000108 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 S2308000108 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. Every Stellantis warranty extension on file lists the ones Stellantis has filed.

Which vehicles does S2308000108 cover?

The manufacturer filed it against 3 model years: 2023 Ram 3500, 2023 Ram 4500, 2023 Ram 5500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
