Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 114 complaints with NHTSA since 2015. 81 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.
On August 17, 2026, at approximately 96,685 miles, my 2024 Cadillac Escalade ESV equipped with the 6.2L L87 V8 engine lost motive power while I was driving on Highway 101 in California. The vehicle stalled, I pulled over, and I was unable to restart it. The vehicle was towed to the dealer.

My engine had a malfunction. My safety was put at risk due to not knowing if the vehicle would stop before I was able to safely get it to be checked. The dealer has been confirmed by the dealer as engine failure due to bearing failure. This was determined by metal pieces in the oil pan.

Common questions
Source: NHTSA, 49 CFR 579.5Is Cadillac PIE0809A 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 PIE0809A 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 PIE0809A cover?
The manufacturer filed it against 2 model years: 2025 Cadillac Escalade, 2024 Cadillac Escalade. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
