2018 CHEVROLET MALIBU — Complaint #2067228
Open-data reference.
NHTSA Complaint about FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM:MASS AIR FLOW (MAF) SENSOR filed February 19, 2025
NHTSA complaint #2067228 (ODI reference 11643747) concerns a 2018 CHEVROLET MALIBU and was filed on February 19, 2025. The owner reports the failure occurred on January 1, 2025. The vehicle had 76,000 miles on the odometer at the time of the incident. The report was geocoded to Nebraska based on the filer's self-reported location. The affected component is categorized as fuel system, gasoline:fuel injection system:mass air flow (maf) sensor, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same CHEVROLET MALIBU cohort independently describe similar fuel system, gasoline:fuel injection system:mass air flow (maf) sensor failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2018 CHEVROLET MALIBU shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2018 Chevrolet Malibu. The contact stated that while on a trip and traveling at high altitudes, the check engine warning light was displayed on the instrument panel. The contact used a code reader which showed that the barometric pressure sensor was defective. Once the contact returned home, the mass air flow sensor was replaced. The following year while traveling in the same region at high altitude levels, the failure recurred. The contact also stated that the engine booster had started to fail due to ice accumulation in the charge air cooler (CAC), which restricted airflow. As a result of the failure, the vehicle failed to accelerate above 25 MPH. Upon investigation, the contact discovered Technical Service Bulletin No: 18-NA-069; which the contact linked to the failure. The dealer was notified of the failure, but the contact was informed that the vehicle was out of warranty. The manufacturer was also notified of the failure and referred the contact back to the dea
