Malibu LFV extreme-cold charge-air icing. See the manufacturer document, vehicle conditions, exclusions and questions for a qualified shop before assuming a repair.
This is a research summary of a manufacturer communication, not a diagnosis for your car, a DIY repair procedure or confirmation of warranty or recall eligibility. No qualified technician has approved a repair for your individual vehicle here.
This historical communication is conditional. The current revision, VIN/build eligibility, measured diagnosis and any warranty or recall decision are not established here. Ask the manufacturer or a qualified shop to check the complete current document.
Read the General Motors original: Malibu LFV charge-air cooler icing in extreme cold · Check open recalls by VIN at NHTSA Source date: 2023-07; research checked: 2026-11-01.
What prompted this manufacturer document
- At extreme cold, charge-air cooler icing can accompany hesitation, stalling or low power with these codes.
Which vehicle conditions must be checked
Each row below retains its own conditions. Do not combine engines, years or models across rows to create new applications. A listed model is not proof that a particular VIN is affected.
- Chevrolet Malibu · 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023 · 1.5L LFV
- The source condition is approximately 0°F (-18°C) or below.
- Moisture alone is not proof of the icing fault; exclude leaks.
- Do not replace an already updated cooler merely because this bulletin exists.
Codes recorded in this document
A root listed only as an appearance has no separately verified meaning here. Preserve every suffix and module name; a shared root does not transfer a repair branch to another vehicle.
| Root | Raw form | Meaning in this source, if established |
|---|---|---|
| P0299 | P0299 | Appears in the document; individual meaning not verified |
| P0234 | P0234 | Appears in the document; individual meaning not verified |
| P2227 | P2227 | Appears in the document; individual meaning not verified |
| P00C7 | P00C7 | Appears in the document; individual meaning not verified |
What an owner can record safely
- Record ambient temperature and whether the problem follows cold operation.
Bulletin eligibility questions
The source uses these gates before choosing a professional diagnostic branch. A missing answer means applicability is unknown; passing one gate never authorizes a repair.
- Extreme-cold context
What the source does not prove
- Do not install a homemade radiator cover or assume all condensation is a fault.
- A code or message alone does not establish a failed part, a safe-to-drive decision or an approved repair for this VIN.
- A service bulletin is not automatically a recall or free warranty repair. Confirm current eligibility directly.
Questions for the repair shop
- Was icing verified, were leaks excluded, and is the cooler already the updated version?
- Does a later revision or a current recall change the source's original advice?
- What measurement or inspection confirms the cause, and how will the repair be verified?
