“**Subject:** Formal Safety Defect Complaint: Premature Failure of Completed Recall Remedy (NHTSA Campaign 13V173000 / GM Recall 13136) Resulting in Sudden Loss of Power Steering **VEHICLE INFORMATION** * **Year/Make/Model:** 2012 Buick LaCrosse Hybrid (eAssist) * **VIN:** [XXX] * **Current Mileage:** [Insert Current Mileage] **DESCRIPTION OF SAFETY DEFECT & INCIDENT** This vehicle was previously serviced under NHTSA Campaign 13V173000 to resolve an inherent defect in the Generator Control Module (GCM) that presents a severe stalling and trunk fire risk. On 9-9-26, under normal driving conditions in ambient temperatures of approximately 95°F and after covering a distance of 10 miles, the manufacturer-installed remedy component suffered a premature, catastrophic thermal failure. The replacement GCM ceased regulating and delivering power to the vehicle’s 12-volt system. The resulting critical voltage drop forced the vehicle into an emergency load-shedding protocol, abruptly disabling the air conditioning system. Shortly thereafter, the severe drop in operating voltage caused a total, sudden failure of the Electronic Power Steering (EPS) while the vehicle was…”

“Hello I have a 2012 Buick lacrosse, when I first bought the vehicle I notice that the service stability track light would come on and immediately after would follow that my motors speed had been reduced. After learning all of this about the vehicle I searched if there was any recalls concerning this matter and in fact found that 2012 Buick lacrosse did have a recall for the service stability track but when I made the call for my vehicle I was told that my car wasn't part of that recall. I'm now dealing with this problem and to the best of my knowledge and research, I found out as well that if the service stability track was to start acting up it could cause my vehicle to come to a stop and could very much so cause a horrific accident. So I'm asking if you could please take it in consideration to make it to where all of the 2012 Buick lacrosse 3.6L should have the recall for the service stability track. Thank you for your time and hope that you make the better judgement call to bring this to light and make it to where all 2012 Buick lacrosse owners are able to get this situation fixed or brought to there attention before a problem or accident. Thanks [XXX]”
