GM bulletin PIP6032A
What it saysThis Preliminary Information communication advises the technician on possible sources of transmission fluid leaks from the transmission oil filter or cooler line seals . NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Jan 29, 2025, received Feb 3, 2025, about the power train. It names 16 model years across Chevrolet and Buick (2019–2025). 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 16 model years this bulletin names have filed 1,734 complaints with NHTSA since 2015. 369 of them name Power Train — 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 2019 Chevrolet Malibu, the 23 owners who gave an odometer reading for Power Train reported it at a median of 39,737 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I need my pistons and rings replaced. My car only has 57,000 miles. My car has been diagnosed with excessive piston blowby from 2 different independent service centers. Both times I have been to Chevy to get it fixed under warranty, they’ve charged me $200 for diagnostics each time and told me it is my PCV valve that needs fixed.
2020 Chevrolet Malibu · Power Train · filed with NHTSA Mar 16, 2022
At 10,000 miles my 2019 Chevrolet Malibu started to sputter and lose power. Taking off at a green light, driving on highways, turning at intersections, or turning against traffic has all become dangerous because the car will not gather enough power to go, leaving my car stuck on roads and in the middle of intersections.
2019 Chevrolet Malibu · Power Train · filed with NHTSA Aug 13, 2020
Engine light is on and vehicle is sluggish on hills and keeping up in traffic. Rpms run high if I try. Error code p0299 shows on scanning device- turbo under boost. I have 112,000 miles and need turbo replaced already. this vehicle is very well maintained. I did see a special notice for the GX version of this vehicle.

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 PIP6032A 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 PIP6032A 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 PIP6032A cover?
The manufacturer filed it against 16 model years across 2 brands (Chevrolet and Buick): 2024 Buick Encore, 2023 Buick Encore, 2022 Buick Encore, 2021 Buick Encore, 2020 Buick Encore, 2025 Chevrolet Equinox and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
