I WAS SITTING AT A RED LIGHT, WITH MY FOOT FIRMLY ON THE BRAKE. SUDDENLY IT STARTED TO MOVE AND SUDDENLY TOOK OFF AND HIT THE CAR IN FRONT OF ME (THE CAR HAD MOVED UP SIGNIFICANTLY, BUT I HADN'T, SO IT HAD A LOT OF MOMENTUM WHEN IT HIT)! AFTER THE ACCIDENT REPORT WAS FILED, I TRIED TO START THE CAR TO LEAVE, BUT THE CAR WOULDN'T START. ADDITIONALLY, A TON OF ERROR MESSAGES WERE FLASHING, AS WELL AS ALL INDOOR AND OUTDOOR LIGHTS FLASHING, EVEN THE DECORATIVE PANEL BLUE STRIP LIGHTS. I WAS TERRIFIED. I HAD TO HAVE IT TOWED FROM THE SCENE. AT FIRST, THE OFFICER DIDN'T BELIEVE ME, THAT IT WAS THE CAR'S FAULT, NOT MINE, BUT ONCE SHE SAW WHAT WAS HAPPENING, SHE BELIEVED ME. THE TOW TRUCK DRIVER SAID THE CAR WAS POSSESSED, HE HAD NEVER SEEN ANYTHING LIKE THIS BEFORE. THE CAR HAD ALMOST 53,000 MILES ON IT, ONE YEAR TO GO WITH PAYMENTS, AND I HAD BEEN PLANNING TO KEEP IT ONCE IT WAS PAID OFF, UNTIL THIS HAPPENED. IT COULD HAVE BEEN SO MUCH WORSE. WHAT IF IT HIT PEDESTRIANS CROSSING THE STREET? I WAS AT A COMPLETE STANDSTILL. WHEN MY MECHANIC EVALUATED IT, A BUNCH OF ERROR CODES PRINTED OUT, ONE OF WHICH WAS U0121 MULTI-AXIS ACCELERATION SENSOR LOST COMMUNICATION WITH ELECTRONIC BRAKE CONTROL MODULE. I'M PRETTY SURE THIS WAS WHAT CAUSED THE ACCIDENT, BUT BOTH GENERAL MOTORS AND MY CHEVROLET DEALER SAY THIS MEANS NOTHING. I SOLD THE CAR AND BOUGHT A MITSUBISHI MIRAGE. I WILL NEVER BUY A CHEVY AGAIN. ALL OVER THE UNITED STATES, ELECTRICAL PROBLEMS ARE HAPPENING TO OTHER CHEVY'S (MY MAKE, MODEL AND YEAR ALONE) - SO FAR ABOUT 167 THAT I'VE READ ABOUT, BUT NO ONE'S DOING ANYTHING ABOUT IT.

DURING WARM WEATHER, BRAKES WILL REMAIN ENGAGED WHEN BRAKE PEDAL IS RELEASED. PUMPING BRAKES CAN HELP TO RELEASE BRAKES. IF FOOT IS NOT ON THE ACCELERATOR, THE CAR WILL RAPIDLY COME TO A STOP. I TOOK THE CAR INTO THE DEALERSHIP WITH THESE ISSUES AND IT WAS DETERMINED TO BE THE BRAKE PEDAL PIVOT BUSHING STICKING OR EXPANDING. THE BRAKE PEDAL ARM AND BOTH SIDE RETAINERS WERE REPLACED UNDER EXTEMDED WARRANTY WITH RELIEF FROM SYMPTOMS FOR ONE YEAR. FOLLOWING SUMMER AND THE SYMPTOMS ARE PERSISTING. I BRING THE CAR BACK TO THE DEALERSHIP AGAIN AND THIS TIME THEY FIND THE BRAKE PEDAL POSITION SENSOR ARM LOOSE CAUSING ERRATIC PEDAL POSITION. THEY REPLACED THE BPP SENSOR AND RETAINER AND THE PROBLEMS SUBSIDE. NOW I AM ON THE THIRD SUMMER OF OWNING THIS VEHICLE AND IN THE SAME EXACT MONTH EVERY YEAR I BEGIN TO HAVE ISSUES WITH THE BRAKES NOT OPERATING PROPERLY. THIS SAME ISSUE IS BEING REPORTED BY OTHER OWNERS OF THIS VEHICLE AND I AM IMPLORING THE NHTSA TO INVESTIGATE THIS MATTER BEFORE A PARTY IS SERIOUSLY INJURED.

BROUGHT TO DEALERSHIP TWICE. FIRST TIME THEY REPLACED A SENSOR, SECOND TIME THEY COULD ADVISED THEY DIDN'T KNOW AND TO BRING IT BACK IF IT HAPPENED AGAIN. THIRD TIME BROUGHT TO AN INDEPENDENT MECHANIC WHO ADVISED IT WAS RELATED TO THE ECO AND WE SHOULD BRING TO A DEALER. EXTREMELY CONCERNED FOR SAFETY AND WE HAVE 3 CHILDREN AND FREQUENTLY DRIVE THROUGH MINNEAPOLIS/ST PAUL AREAS WHERE THERE IS HEAVY TRAFFIC AND CONSTRUCTION.

FOR ALMOST 2 MONTHS, THE BRAKES ON THE CAR DO NOT RELEASE. THIS ISSUE STARTED DURING A SNOW STORM IN THE WINTER BUT HAS CONTINUED. IT IS NOT ALL THE TIME, BUT SEEMINGLY EVERY EVENING AFTER WORK THAT THE BRAKES ARE LOCKED UP. MORNINGS ARE USUALLY FINE. THE PEDAL STAYS DEPRESSED, WHICH I DIDN'T REALIZE FOR A FEW WEEKS, LEADING TO CRUISE CONTROL NOT WORKING, SLUGGISH MPG RATES, EXTRA WEAR ON THE BRAKE PADS, ENGINE STRAIN, LOWER SPEEDS THAN EXPECTED, NO COASTING, DIFFICULT ACCELERATIONS, AND TAIL LIGHTS STAYING ON AFTER EXITING THE VEHICLE. THE PEDAL CAN BE RELEASED MANUALLY BY KICKING IT UP WITH YOUR FOOT, BUT THIS IS REALLY TIRESOME IN TRAFFIC AND LONG COMMUTES. *TR

I PURCHASED MY 2013 MALIBU ECO IN NOVEMBER OF 2013. ON OR ABOUT MARCH 1, 2014 WE WERE TRAVELING AT APPROXIMATELY 70 MILES PER HOUR WHEN WERE CUT OFF BY A TRUCK. I HAD TO SLAM ON THE BRAKES WITH SOME FORCE TO AVOID A COLLISION AND UPON DOING SO THE MOTOR LOST ALL POWER AND BEGAN TO SHAKE WITH MY SPEED GOING FROM 70 DOWN TO 20 MPH. I COULD NOT REGAIN THE SPEED LIMIT AND HAD TO PULL OVER THINKING IT WAS BECAUSE I WAS DRIVING USING THE MANUAL OPTION. I WAS IN 6TH GEAR WITH CRUISE CONTROL ON. I WAS ABLE TO GET THE VEHICLE HOME AFTER A 90 MILE DRIVE AT ABOUT 45 MPH. I DID NOT REPORT THIS TO THE DEALER AS THE NEXT MORNING I STARTED THE VEHICLE AND IT SEEMED FINE. A MONTH LATER WE TOOK THE SAME TRIP AND THIS TIME THE SAME ISSUE OCCURRED ALTHOUGH IT WAS NOT PRECIPITATED BY A NEAR COLLISION. THE CAR SIMPLY LOST ALL POWER IN WHILE DRIVING CITY STREETS. THE CLUTCHES IN THE TRANSMISSION WERE GRINDING AS I TRIED TO GET THE CAR TO GAIN ENGINE POWER. AGAIN I FOOLISHLY DID NOT REPORT TO THE DEALER AS I WAS ABLE TO GET THE VEHICLE BACK TO SPEED AFTER ABOUT A HOUR OF DRIVING. IN JUNE THE SAME ISSUE APPEARED AND I FINALLY DID TAKE IT INTO THE DEALER AND THEY REPLACED THE BRAKE PEDAL POSITION SENSOR SHORTED CAUSING TRANSMISSION NOT TO DOWNSHIFT PROPERLY. THEY COULD NOT REPLICATE PROBLEM. IN LATE JULY THE SAME ISSUE REOCCURED AND THIS TIME THE DEALER PERFORMED A RECALL ON THE TURN SIGNAL LAMP OUTAGE. THEN IN EARLY SEPTEMBER THE ISSUE REOCCURED WHILE MY WIFE WAS DRIVING LOCALLY. THE CARS BRAKES WERE SO HOT THE WHEEL WEIGHTS AFFIXED TO THE FRONT TIRES WERE LAYING IN OUR DRIVEWAY HAVING MELTED OFF. THIS TIME THE DEALER REPLACED THE MASTER CYLINDER, FRONT ROTORS, BRAKE PADS AND WHEEL WEIGHTS. IN EARLY OCTOBER I WENT TO HAVE AN OIL CHANGE AND TIRE ROTATION AND WHEN THEY TOOK THE FRONT DRIVER WHEEL OFF THE FRONT BRAKE ROTOR RETAINING BOLT FELL OUT. *TR

I PURCHASED THIS VEHICLE JANUARY 2014 AT 5,000 MILES. I BEGAN TO NOTICE TROUBLE WITH BRAKES AND ACCELERATION A COUPLE OF MONTHS AFTER. BRAKING WAS NOT SMOOTH OR CONSISTENT AT TIMES. AT TIMES I WASN'T ABLE TO ACCELERATE AND IT FELT LIKE I WAS DRIVING WITH PARKING BRAKE ON. LATER I NOTICED THAT I COULD CONTROL THIS BY LIFTING THE BRAKE PEDAL WITH MY FOOT. THE BRAKE PEDAL WASN'T RELEASING ON ITS OWN. I TOOK THE CAR TO A CHEVROLET DEALERSHIP (SAME DEALER THAT FIXED ANOTHER RECALL ON THIS CAR FOR ELECTRICAL WIRING RECALL) TO HAVE THE BRAKES CHECKED OUT. THEY SAID THE BRAKE ASSEMBLY WAS FAULTY AND KEPT THE CAR FOR A FEW DAYS. SINCE THE PART HADN'T BEEN DELIVERED AND I NEEDED A VEHICLE ASAP, I PICKED UP MY CAR TO USE UNTIL THE PARTS CAME IN TO THE DEALER. WHEN I WAS LEAVING THE SERVICE CENTER, I WASN'T ABLE TO GO IN REVERSE. I MADE SURE THE EMERGENCY BRAKE WASN'T ON AND EVEN TRIED TO TURN IT ON AND OFF TO MAKE SURE IT WAS DEFINITELY OFF. THE TIRES WERE ALIGNED STRAIGHT AND TRY AS I MAY, THE CAR WOULD NOT GO IN REVERSE. I WENT IN TO THE SERVICE DEPARTMENT AND SPOKE WITH THE TECHNICIAN WHO CAME OUT AND TRIED REVERSING THE CAR WITHOUT SUCCESS AT FIRST. HE EVENTUALLY GOT THE CAR TO GO IN REVERSE AND DIDN'T SEEM CONCERNED OR THOUGHT THIS TO BE SIGNIFICANT. THE NEXT DAY, I WAS DRIVING ON THE SPEEDWAY AND SUDDENLY I COULD NOT ACCELERATE PAST 50 MPH REGARDLESS OF HOW MUCH I PRESSED ON THE ACCELERATOR. THE CAR STARTED TO SLOW DOWN ON ITS OWN AND I WAS TERRIFIED THAT OTHER VEHICLES WOULD HIT THE BACK OF MY CAR. I GOT OFF THE HIGHWAY ON THE NEXT EXIT AND MY VEHICLE STARTED TO SMOKE AND SCRAPING/GROANING SOUNDS WERE HEARD. I BARELY MADE IT TO A SHOPPING CENTER WHERE I HAD TO CALL A TOW TRUCK TO TAKE THE CAR BACK THE DEALER FOR SERVICE. TOMORROW IT WILL BE ONE WEEK SINCE I TOOK MY CAR IN AND I STILL DON'T KNOW WHEN THE PARTS WILL BE DELIVERED OR WHEN MY VEHICLE WILL BE FIXED. *TR

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
