during a regular drive the check stabiltrack system message popped up on the dash in the middle circle and then the little car with the squiggly lines behind it popped up and the check engine light came on and started blinking. Immediately I noticed lack of steering control, the car's speed was accelerating and decelerating on its own, jerking and stalling also was observed. As of now the car sits in my driveway because I don't trust the safety of it. I literally feared my life was in danger driving it because of the lack of handling and the acceleration shifts that were so random. So I returned home, as I pulled into the yard the vehicle jerked hard while I was attempting turn into the driveway causing me to hit my mailbox and damaged the side fender and front bumper. no one was injured but the car was damaged as stated before and I'm scared to drive it anywhere. The unpredictable behavior displayed in the vehicle puts other drivers at risk as well because I can't control the vehicle properly. so I'm guessing all in all its a malfunction somewhere in the electrical system. I have read about recalls in my type of vehicle involving the ESC and it appears to be what is happening with mine. As of now it sits in my driveway I need a remedy and fast because that was my only source of transportation and I'm a single mother of four with a lot to take of and no way to do it.

I have been dealing with this problem for over 7 months now. My Buick Lacrosse '12, while driving it (doesn't matter the speed) all of the suddent it starts locking and unlocking, immediately after the speed drops and the car comes to a complete stop. I have little children that ride with me in the car- while driving on the interstate this is a HUGE LIFE HAZARD, because I can't control when the car stops. I have taken it to multiple shops, non a single one of them can find anything wrong. No codes come up when they check for it. This is beyond frustrating. I see other Buicks have been recalled due to this issues. PLEASE HELP!! I am seriously concerned that me and my family could have a fatal accident because my car stops on the interstate with out warning. My name is [XXX], my husband is [XXX]- contact cell [XXX].

Official recalls
5Dec 22, 2021
General Motors, LLC (GM) is recalling certain 2010-2013 Buick Lacrosse, 2012-2013 Buick Regal, and 2013 Chevrolet Malibu vehicles sold or ever registered in Connecticut, Delaware, the District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, or Wisconsin. These vehicles may have rear toe links that received an improper amount of electrocoating (e-coat) corrosion protection, which could cause the e-coat to become brittle and break away when contacted by road debris. Over time, the e-coat may chip away, exposing the metal toe link and making it more susceptible to corrosion. Corrosion may eventually cause the toe link to thin and ultimately fracture.
Consequence & remedy
Consequence: A rear toe link fracture may reduce the driver's ability to control the vehicle, increasing the risk of a crash.
Remedy: Dealers will replace the rear suspension toe links and adjuster fasteners, free of charge. Owner notification letters were mailed January 27, 2022.

2AQ14001 · Sands Chevrolet/hybrid System Fire/stall
Opened May 2, 2014 · Closed May 22, 2016
Status: closed (inferred from source dates) · Electrical System
NHTSA 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)).NHTSA 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 NHTSA?s information request encompassed all possible reference codes for General Motors recall 13V-173, NHTSA issued another IR letter to Sands Chevrolet on June 8, 2015.Again, a response letter was received on June 9, 2015.NHTSA?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.NHTSA 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.
RQ13003 · Generator Control Module Fires
Opened Jul 5, 2013 · Closed Jul 22, 2014
Status: closed (inferred from source dates) · Electrical System:propulsion System:traction Battery
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
