I FILED A COMPLIANT JAN. 25, 2021 (#11389775) IN REFERENCE TO MY CAR STALLING. WHICH HAS BEEN CONTINUOUSLY HAPPENING THE MAJORITY OF THE TIME I HAVE OWNED THE VEHICLE. I WAS CONTACTED BY MY MECHANIC THAT MY PROBLEM FITS THE ISSUES ON RECALL #13V173000 WHICH MY VIN # DOES NOT PULL AS A RECALL. I CALLED GM LAST YEAR IN REFERENCE TO THE SAME ISSUE WHICH THEY STATED BECAUSE MY VIN WAS NOT INCLUDED IN THE RECALL THAT THERE WAS NOTHING THEY CAN DO. I HAVE NOTICED THAT THERE ARE QUITE A FEW BUICK LACROSSE OWNERS THAT HAVE THE CARS THAT ARE EQUIPPED WITH THIS E-ASSIST ARE HAVING THE SAME PROBLEMS AND ARE BEING TOLD THAT THEIR VIN # ARE NOT INCLUDED. IT SEEMS THAT GM HAS OVERLOOKED A LOT OF CARS THAT SHOULD HAVE BEEN INCLUDED IN THIS RECALL. I HAVE HAD MY CAR FOR A LITTLE OVER 5 YEARS AND MY CAR HAS NOT OPERATED CORRECTLY DUE TO THIS ISSUE. I HAVE ATTACHED THE TEXT MESSAGE I HAVE RECEIVED FROM MY LICENSED MECHANIC.

WHILE DRIVING MY CAR ON THE HIGHWAY THE CAR WOULD COMPLETELY POWER DOWN. AFTER SITTING IN THE EMERGENCY LANE FOR AN HOUR THE CAR WOULD START AND OPERATE AS IF NOTHING WAS WRONG. I HAVE HAD THE CAR FOR ALMOST 5 YEARS AND THIS HAS BEEN HAPPENING THE MAJORITY OF THE TIME. I HAVE SPENT OVER $6000 IN REPAIRS WITH NO SUCCESS.

WHILE DRIVING ON A CITY STREET AT 20 MPH THE ENGINE STARTED KNOCKING AND THE SERVICE CHARGING SYSTEM LIGHT CAME ON. A FEW MINUTES LATER AS I WAS BACKING INTO A PARKING SPOT IN A PARKING LOT AT WORK THE CAR SHUT OFF AND WOULD NOT RESTART. I HAD THE CAR TOWED HOME AND A MECHANIC LOOKED AT IT AND SEEN THAT THE ENGINE WAS HYDRO-LOCKED WHICH HE WAS ABLE TO UNLOCK. AFTER CHECKING THE SPARK PLUGS, COILS, VALVE COVER, TIMING, OIL, COOLANT, ALTERNATOR, STARTER, BATTERY, FUSE BLOCK AND WIRING HARNESS, THE PLUGS NEEDED REPLACED, THERE WAS METAL SHAVINGS IN THE OIL AND SOME TYPE OF FLUID IN SOME OF THE SENSOR PLUGS ON THE MOTOR. AFTER REPLACING THE PLUGS AND OIL AND OIL FILTER AND CLEANING OTHER COMPONENTS I WAS DRIVING THE CAR TO THE STORE AND THE MALFUNCTION LIGHT CAME ON ALONG WITH SERVICE CHARGING SYSTEM AND SERVICE STABILITY TRAK I STOPPED AT AUTOZONE TO HAVE THEM SCAN THE ENGINE AND THE CODE CAME BACK WITH MALFUNCTION WITH SPARK PLUG #3 SO I BOUGHT A NEW PLUG AND ON THE WAY HOME ABOUT 10 MINS AFTER LEAVING AUTOZONE THE CAR COMPLETELY SHUT DOWN IN THE MIDDLE OF THE ROAD. MY MECHANIC CAME AND WE WERE ABLE TO GET IT TO RESTART AND GET IT BACK HOME WHICH WAS ONLY A FEW BLOCKS. AFTER DOING ANOTHER TUNEUP AND GETTING IT TO DRIVE AGAIN 2 BLOCKS FROM MY PLACE A ROD WENT RIGHT THROUGH THE FRONT BOTTOM OF THE ENGINE BLOCK WHICH THEN REQUIRED FOR A NEW ENGINE. I CALLED GM, BUICK, THE CAR LOT I GOT THE CAR FROM AND EVERYONE SAID THERE WAS NO LONGER A WARRANTY ON THE VEHICLE SO THE ONLY CHOICE I WOULD HAVE WAS TO PAY $10,000 FOR A NEW ENGINE NOT INCLUDING LABOR PRICE. MY CAR INSURANCE DIDN'T COVER MECHANICAL FAILURES EITHER SO I WAS STUCK WITH A $30,000 CAR THAT WASN'T DRIVABLE. CAUSE IS UNKNOWN. I BOUGHT THIS CAR IN JAN. 2015 WITH 31,000 MILES ON IT AND THIS HAPPENED IN NOV 2015 WITH 40 SOME THOUSAND MILES ON IT. ROUTINE MAINTENANCE WAS KEPT UP TO DATE ALSO.

MY 2012 BUICK LACROSSES NEWEST PROBLEM IS ONE THAT ACTUALLY SCARES ME. I CAN BE DRIVING ALONG AT 65 MILES AN HOUR AND IT WILL KINDA JERK A COUPLE OF TIMES, THEN USUALLY IT WILL FLASH 'SERVICE THE STABILITY TRACK' THEN I LOSE POWER STEERING AND IT DIES. I'M LUCKY IF I CAN MAKE IT TO THE SIDE OF THE ROAD.I LIVE IN A RURAL AREA AND THE HIGHWAYS AROUND HERE ARE TWO LANE WITH MINIMUM SHOULDERS. SO WHEN THE CAR DOES THIS IT IS DANGEROUS. IT HAS HAPPENED 5 TIMES NOW. IT WILL RESTART AFTER ABOUT 15-30 MINUTES AND DRIVE JUST FINE. I'VE TAKEN IT TO A MECHANIC AND NOTHING SHOWS UP ON THE COMPUTER, EVERYTHING LOOKS GOOD. BUT ITS NOT, THIS IS BY FAR THE WORST OF THE PROBLEMS I'VE EXPERIENCED WITH THIS CAR AND THERE HAVE BEEN QUITE A FEW.

NOW THE VEHICLE IS AT THE DEALERSHIP JUST SITTING THERE AND I HAVE NO WAY TO WORK AND STILL HAVE TO PAY CAR NOTE AND INSURANCE ON A VEHICLE I DON'T EVEN HAVE ACCESS TO ANYMORE. THE DEALERSHIP IS DIXON AUTO AND BODY SALES AND I'M STUCK WAITING WITH NOTHING TO LOOK FORWARD TO AS FAR AS A RIDE.

AQ14001 · 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
