RQ13003 Recall Query Closed

Vehicle: CHEVROLET MALIBU ECO View model page

NHTSA investigation RQ13003 is a Recall Query opened on 2013-07-05 and currently closed. The subject of record is CHEVROLET MALIBU ECO, which places this file inside the Office of Defects Investigation queue for CHEVROLET. Latest activity on this investigation was logged on 2014-07-22 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.

A Recall Query like RQ13003 evaluates whether a previously issued recall is actually fixing the problem. NHTSA opens an RQ when owners continue to report the original defect after the recall remedy is installed, or when completion rates fall short of the agency's expectations for that risk tier.

Investigators summarized the matter as follows: "On July 5, 2013 the Office of Defects Investigation (ODI) opened Recall Query RQ13-003 to investigate whether the service procedures utilized in recall bulletins 13136 and 13142 for safety recall 13V-173 were sufficient..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related CHEVROLET files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

On July 5, 2013 the Office of Defects Investigation (ODI) opened Recall Query RQ13-003 to investigate whether the service procedures utilized in recall bulletins 13136 and 13142 for safety recall 13V-173 were sufficient to identify the safety defect in the subject vehicles. These safety recalls were issue on May 3, 2013 to address the improper function of the Generator Control Module (GCM) in certain model year (MY) 2012-13 Buick LaCrosse and Regal and MY 2013 Chevrolet Malibu Eco equipped with eAssist. This condition may result in a loss of battery charge, engine stall and/or inability for the vehicle to start. In severe cases it may also lead to odor, smoke and possibly a fire in the trunk. During discussions with General Motors (GM), ODI was informed that the subject vehicles could be separated into 4 distinct build populations, or groups. Group A contained vehicles built from the start of production through 3/19/2012. Group B involved vehicles built from 3/20/2012 to 8/20/2012, group C from 8/21/2012 to 12/31/12, and group D from 1/1/2013 onwards. Bulletin 13136 instructed dealers to inspect and, if necessary, replace the GCM for vehicles in groups A or C. Bulletin 13142 instructed dealers to replace the GCM of any vehicle in group B. Group D vehicles were not recalled. All eAssist vehicles have a Powerpack which contains a BAS (belt alternator-starter) Power Inverter Module (BPIM)/Accessory Power Module (APM) and a 115-V Lithium-Ion battery. The Powerpack is known by GM's Part Description System as the GCM and Battery Module. The BPIM/APM contains 3 multi-layered printed circuit boards (PCBs) comprised of conductive layers separated by isolating layers. Vehicles built within the time periods of groups A and B had PCBs using single isolation layers. Vehicles build in group C had dual isolation layers on 1 of the 3 PCBs, and group D had all 3 PCBs built with dual insulation. Adding dual insulation to a PCB makes it more robust to material and manufacturing variat

About This Investigation Type

A Recall Query (RQ) evaluates the effectiveness of a previously issued recall. NHTSA opens an RQ when consumer complaints suggest that a recall remedy may not be adequately addressing the safety issue, or when the recall completion rate appears insufficient.
