What it saysThis Preliminary information communicates the proper procedures for doing an alignment on a vehicle with super cruise that has a pulling complaint. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Jan 23, 2024, received Feb 12, 2024, about the steering. It names 16 model years across Chevrolet, GMC and Cadillac (2021–2024). 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.

Under heavy acceleration the vehicle swerves from lane to lane and the operator is unable to counter the steering. The behavior continues until the acceleration is halted. The vehicle was grounded due to it being deemed unsafe by the originating dealership technician and repairs were attempted but were unsuccessful.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM PIT6115 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 PIT6115 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 PIT6115 cover?
The manufacturer filed it against 16 model years across 3 brands (Chevrolet, GMC and Cadillac): 2024 Cadillac Escalade, 2023 Cadillac Escalade, 2022 Cadillac Escalade, 2021 Cadillac Escalade, 2024 Chevrolet Silverado, 2023 Chevrolet Silverado and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
