GM bulletin PIT5214F
What it saysThis Preliminary Information communication provides information to the technician about vehicles that have had multiple repair attempts that are being performed on customer?s vehicles that exhibit vibration conditions… NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Nov 14, 2023, received Dec 18, 2023, about the suspension. It names 239 model years across Chevrolet, GMC, Buick and Cadillac (2016–2022). 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 238 model years this bulletin names have filed 31,723 complaints with NHTSA since 2015. 164 of them name Suspension — 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 the 2018 Chevrolet Silverado, the 15 owners who gave an odometer reading for Suspension reported it at a median of 16,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Several different instances I've had my parking brake release as soon as I go to move after being parked for a long period of time. (I never set my parking brake to begin with so I don't understand why it keeps telling me it's released) Once it tells me it's been released, it's followed by a rough jersey of the car and then I'm able to…

2018 Chevrolet Trax · Suspension · filed with NHTSA Sep 19, 2019
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 PIT5214F 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 PIT5214F 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 PIT5214F cover?
The manufacturer filed it against 239 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2019 Buick Cascada, 2018 Buick Cascada, 2017 Buick Cascada, 2016 Buick Cascada, 2022 Buick Enclave, 2021 Buick Enclave and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
