Chevrolet filed this with NHTSA as a service bulletin dated Aug 13, 2024, about the forward collision avoidance. It names 1 model year (2024). 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.

What owners reported

Source: NHTSA complaint database

Owners of the 1 model year this bulletin names have filed 132 complaints with NHTSA since 2015. 45 of them name Forward Collision Avoidance — 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.

Contining with issue referenced in 11701484. This morning (1/28/26) when leaving my home, I backed out of my driveway. Once I put the car into drive, the forward collision warning went off and locked up my car. The brakes would not release and I could not move out of the way of oncoming traffic.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Chevrolet PIT6164 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 PIT6164 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 GM warranty extension on file lists the ones GM has filed.

Which vehicles does PIT6164 cover?

The manufacturer filed it against 1 model year: 2024 Chevrolet Blazer. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
