Defect investigations

Sands Chevrolet/Hybrid System Fire/StallOpened May 2, 2014, closed May 22, 2016

the federal safety agency opened AQ14-001 to determine whether Sands Chevrolet of Surprise, Arizona complied with the requirements of the National Traffic and Motor Vehicle Safety Act, 49 U.S.C. Chapter 301 (Safety Act) and its implementing regulations. The Safety Act requires, among other things, that a manufacturer notify its dealers of defects related to motor vehicle safety and non-compliances with Federal Motor Vehicle Safety Standards and, in turn, that a dealer not sell and deliver a new vehicle subject to a recall unless the recall remedy has been performed (49 U.S.C. ?? 30112(a), 30120(i)).the federal safety agency issued an information request (IR) letter to Sands Chevrolet on May 5, 2014.Sands Chevrolet responded to this request on May 22, 2014.To ensure the federal safety agency?s information request encompassed all possible reference codes for General Motors recall 13V‑173, the federal safety agency issued another IR letter to Sands Chevrolet on June 8, 2015.Again, a response letter was received on June 9, 2015.the federal safety agency?s investigation indicated that Sands Chevrolet did sell and deliver recalled vehicles that did not have the recall remedy completed at the time the vehicles were delivered to the customers.the federal safety agency therefore concluded that Sands Chevrolet was liable for civil penalties for violations of the Safety Act, pursuant to 49 U.S.C. ? 30165.Under a Settlement Agreement dated March 24, 2016, Sands Chevrolet represented that it improved its processes to verify that it checks every vehicle for recalls prior to delivery to the purchaser and that it has not sold and delivered any unremedied new motor vehicles since June 9, 2015.Sands Chevrolet also represented that it now also checks for open recalls on every customer vehicle brought in for service, and that it checks for open recalls on every used trade-in vehicle, regardless of make or model, and takes steps to have all used trade-in vehicles repaired prior to retail sale. Sands Chevrolet admitted to violating the law and must pay civil penalties in the amount of $40,000.This Audit Query is closed.

Generator Control Module FiresOpened July 5, 2013, closed July 22, 2014

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 variations, and ultimately less susceptible to an electrical short circuit and subsequent failure.Through initial analysis of the GCM failures, GM identified that vehicles within group B contained PCBs that were contaminated during production due to increased production volumes that resulted in inadequate quality control.GM also noted that GCM failures occurred early in the life of the vehicle (typically <1000 miles).Therefore a service procedure was developed to replicate early life failures by subjecting the GCM to high current loads which would cause the identified failure mechanism (copper migration) to occur quickly and reveal any underlying PCB defect.Although groups A and C were built with PCBs containing single layer PCBs, they were built using better quality control, and as the data supports, experienced significantly lower failures.GM advised that for these reasons the two different service procedures were used in the Recall 13V‑173 population.In response to ODI's Information Request (IR) GM submitted 234 unique reports related to the alleged problem. It was noted that 197 (84%) of the received reports fell into the group B population.The 2 fire incidents noted were events in which flames were evident and/or damage was experienced outside of the GCM. Both of these incidents involved group B vehicles. One hundred four warranty claims were also submitted in response to the IR, with 96 claims (92%) from group B.It was also noted that none of the claims from groups A or C occurred after the service procedure was conducted, and that the majority of the A or C incidents occurred during the service procedure.Given the data, ODI believes the ser

There is a water seal leak around the driver side headlight. I have photos showing proof of standing water. It has now caused the headlight, left turn signal, and drivers side brake light to fail. My passenger side headlight is doing the same. I have no headlights, no driverside lights period. I drive 2 children around in this car and it's gotten very dangerous. I contacted GM, and the local dealership and they won't fix it. I'm a [XXX] and don't have the $3200-$5000 I was told the repair would be. It is a problem in certain GM models, Cadillac Srx 2010-2015 having the same issue and the recall being fixed for those drivers. So, I have no choice but to drive around with no headlights, no left blinker, and no driver side brake light with two you children. I have to work and have no other options. It's a catastrophe waiting to happen, I live in the metropolitan area of Atlanta, Georgia. Please help me with this, I am terrified to drive this car around. I've had two people flag me down at a red light to let me know my brake light is out which is terribly dangerous and if it starts raining while I am out I have no headlights. This has become an emergency situation for me and my children. I have photo proof of the water pooling inside the headlight assembly. The seal is so bad that even covered the condensation pools inside the headlight. Please help me get a dealership to fix this issue. They want to charge me $275 for diagnostics and this is already and issue on this model car, reported by many drivers with the recall on the Cadillac. They need to fix it before I end up a casualty to this problem. Thank you so much. I can send a video of the emergency flasher and signal not working. I replaced the headlight in January and the new one never worked. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The driver headlight assembly has water in it and unable to fix it without replacing whole assembly that can be as much as $1500. The light bulb and valance was replaced. The valance was filled with water. The headlight still wouldn’t work. Upon further investigation there is a part sealed into the assembly that also has water in it with no way to get it out or replace. This is a safety risk since i am unable to see on driver side in dark without my light. There are no recalls but have found many complaints on same issue. The part water is in is sealed and shouldn’t have a way for to get in. The only fix is replacing entire assembly. I have no light at all on that side until fixed.
