Active Safety System Malfunction

On April 15, 2014, the Office of Defects Investigations (ODI) opened Preliminary Evaluation PE14-010 based on two complaints alleging incidents of sudden/severe uncommanded braking resulting in rear impact collisions in model year (MY) 2014 Chevrolet Impala vehicles.ODI analyzed all complaints relat... ed to allegations of unwanted brake activations while driving that were provided by GM or submitted to ODI from consumers and has not identified any additional incidents involving sudden, extended (greater than 1 second) autonomous braking.The two crash complaints that were the basis of PE14-010 involved rental vehicles equipped with an Electric Park Brake (EPB) system.Neither vehicle was equipped with Full Speed Range Adaptive Cruise Control (FSRACC) or Forward Collision Alert (FCA) systems. According to GM, brake lights will be illuminated if the service brakes are applied or the EPB system is activated while the vehicle is moving (dynamic EPB brake apply).In a dynamic EPB brake apply, the Electric Brake Control Module (EBCM) initiates a controlled deceleration while activating a chime and a telltale light.If the service brake is applied at any time during dynamic EPB brake apply, the system provides a substantially greater deceleration.Witness statements and analysis of crash data from the two incidents are consistent with inadvertent dynamic EPB brake applications.Both reports alleged beeping noise immediately before the accidents and one pre-crash data report shows a moderate initial vehicle deceleration followed by in increase in deceleration to approximately 0.6g just prior to the vehicle stopping and being struck from the rear.During this investigation, General Motors LLC (GM) inspected the two crash incident vehicles and examined each of the EPB switches to assess potential mechanical and electrical fault conditions.The testing and part examination did not find any evidence of mechanical or electrical failure of the EPB switches and GM did not identify any faults in the subject components or systems that could have caused or contributed to autonomous brake applications in the incident vehicles.According to GM, the evidence indicates the events were caused by inadvertent driver actuation of the EPB switch. Additionally, during this investigation, GM identified a defect condition in the EPB software in approximately 132,921 model year (MY) 2014 through 2015 Chevrolet Impala and MY 2013 through 2015 Cadillac XTS vehicles (Recall No. 14V-541) that could result in failure of the EPB to release after vehicle start-up.In this condition, the electronic parking brake piston actuation arm may not fully retract when the driver disengages the EPB, which may cause the brake pads to stay partially engaged with the rotor.According to GM, the parking brake indicator may not illuminate when the EPB is engaged and the driver may experience poor vehicle acceleration, undesired deceleration during idle coast-down, excessive brake heat, and premature wear to some brake components. If the vehicle is operated for an extended period of time in this condition, there is a potential for the rear brakes to generate significant heat, smoke, and sparks.GM and its supplier, Mando Pyeongtaek, upgraded the EPB software to address brake drag conditions and issued a recall bulletin on September 4, 2014 instructing dealers to reprogram the electronic parking brake control module on all affected vehicles. This preliminary evaluation is closed.The closing of this investigation does not constitute a finding that a safety-related defect does not exist.For additional information regarding this investigation, see Attachment A to this cRead more

ODI IS AWARE 1 MINOR CRASH ALLEGED TO BE RELATED TO A POWER STEERING FLUID LEAK.THE CONSUMER ALLEGED A MINOR CRASH OCCURRED AS THE CONSUMER WAS ATTEMPTING TO PULL INTO A DRIVEWAY AND HAD DIFFICULTY NEGOTIATING THE TURN DUE TO EXPERIENCING HIGH POWER STEERING EFFORTS AND STRUCK A SNOW BANK.IN A LETTER DATED SEPTEMBER 21, 2009, GM INFORMED ODI THAT A CUSTOMER SATISFACTION PROGRAM WILL COMMENCE IN DECEMBER OF 2009 FOR THE ENTIRE US. AS A REMEDY THE POWER STEERING HOSE ASSEMBLY FOR VEHICLES WITH V8 ENGINES AND THE POWER STEERING RETURN HOSE AND CLAMPS FOR VEHICLES WITH V6 ENGINES WILL BE REPLACED WITH UPGRADED COMPONENTS.BASED ON THE LOW FREQUENCIES AND MINOR SEVERITIES OF THE ALLEGED FIRE INCIDENTS AND CRASH,NO SAFETY RELATED DEFECT TREND HAS BEEN IDENTIFIED IN THE SUBJECT VEHICLES.GM'S EXPANDED CUSTOMER SATISFACTION PROGRAM WILL PROVIDE FREE REPAIRS TO VEHICLES EXCLUDED FROM THE ORIGINAL CAMPAIGN.ACCORDINGLY, THIS INVESTIGATION HAS BEEN CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL CONTINUE TO MONITOR COMPLAINTS AND OTHER INFORMATION RELATING TO THE ALLEGED DEFECT IN THE SUBJECT VEHICLES AND TAKE FURTHER ACTION IN THE FUTURE IF WARRANTED.Read more
