NHTSA Complaint about POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM) filed August 29, 2025
NHTSA complaint #2125399 (ODI reference 11683945) concerns a 2020 CHEVROLET MALIBU and was filed on August 29, 2025. The owner reports the failure occurred on August 28, 2025. The vehicle had 88,400 miles on the odometer at the time of the incident. The report was geocoded to Georgia based on the filer's self-reported location. The affected component is categorized as power train:automatic transmission:control module (tcm/pcm/tecm), 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 power train:automatic transmission:control module (tcm/pcm/tecm) 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 2020 CHEVROLET MALIBU shows the complete component-level complaint distribution alongside any active investigations or recalls.
