GM bulletin PIE0716A
What it saysThis engineering information (EI) closure ends the need for gathering further information from technicians in regard to oil leaking from the oil pan. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Jun 30, 2023, received Jul 14, 2023, about the engine. It names 8 model years across Chevrolet, GMC, Buick and Cadillac (2022). 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.

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.

What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 179 complaints with NHTSA since 2015. 43 of them name Engine — 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 contact owns a 2022 Cadillac XT4. The contact stated that while driving at an undisclosed speed, the vehicle was shaking and lost motive power. The messages "Service Stabili-trak" and "Intake and Exhaust Valve To Optimize Performance And Efficiency, Please Schedule Service Now" were displayed. The vehicle failed to restart.

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 579.5Is GM PIE0716A 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 PIE0716A 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 PIE0716A cover?
The manufacturer filed it against 8 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2022 Buick Envision, 2022 Cadillac CT4, 2022 Cadillac CT5, 2022 Cadillac XT4, 2022 Cadillac XT5, 2022 Cadillac XT6 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
