Read by machine from the document NHTSA serves (6 pages), read Sep 30, 2026. A part number is shown only where it matches GM’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

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.

I was driving with my cruise control set at 77 mph in the fast lane of a four-lane highway. There was no one in front of me for more than 3/4 of a mile. A car in the lane to my right apparently triggered the automatic breaking system to the point it slammed on my brakes, pushed me into the steering wheel, and slowed me all the way to 38…

Common questions
Source: NHTSA, 49 CFR 579.5Is GM 24-NA-138 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 24-NA-138 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 24-NA-138 cover?
The manufacturer filed it against 3 model years across 2 brands (Chevrolet and GMC): 2024 Chevrolet Colorado, 2024 Chevrolet Corvette, 2024 GMC Canyon. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
