2014 Chevrolet Impala

NHTSA opened AQ17-002 to determine whether BiCal Chevrolet of Valley Stream, New York (BiCal) has 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 a new vehicle subject to a recall unless the recall remedy has been performed (49 U.S.C. ?30120(i)).NHTSA issued an information request (IR) letter to BiCal on March 15, 2017. BiCal responded to this request on November 8, 2017. On March 16, 2017, an IR letter was issued to General Motors LLC (GM) and a response was received from GM on April 28, 2017. In NHTSA?s view, it had difficulties in obtaining responses to IR letters from BiCal throughout the AQ investigation, including not receiving a response to the first IR until more than three months after the original deadline. Additionally, in NHTSA's view, BiCal failed to provide a full response to the second IR. BiCal does not contest NHTSA's conclusion that it violated the Safety Act by initially failing to provide full and complete responses to the IRs from NHTSA by their deadlines. NHTSA's investigation also indicated that BiCal sold and delivered at least 54 recalled vehicles that did not have the recall remedy completed at the time the vehicles were delivered to the customers.BiCal did not contest NHTSA?s conclusion that it violated the Safety Act by selling and delivering certain new motor vehicles that were subject to a recall before the vehicles were remedied.Under a Settlement Agreement dated March 11, 2019, BiCal agreed to pay compromised civil penalties in the amount of $40,000. This Audit Query is closed.

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 related 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 c

The lighting is unsafe at night, the light does not light up the road so you can safely see what is is front of you, ITs a major design flaw in the light housing, upgraded to a brighter bulb does not help.

Incident

While driving my 2014 Chevrolet Impala Limited Police vehicle, VIN [XXX], the engine unexpectedly shut off. The check engine light illuminated and the vehicle subsequently would crank but would not start normally. A diagnostic scan produced code P069E, Fuel Pump Control Module Requested MIL Illumination. After the failure, the vehicle would crank without starting using the normal ignition. The vehicle was towed home. I attempted to start vehicle using the factory remote-start system. It started as normal with the remote-start system, but shut off after a few minutes. I am reporting this because an unexpected engine shutdown while the vehicle is in motion created a safety risk due to the sudden loss of engine power while driving. I found GM service information addressing P069E and fuel pump control-related conditions on 2014 Chevrolet Impala Limited vehicles, including GM bulletin PI1082. However, this VIN does not appear to be included in a recall or repair campaign for this condition. I am requesting that NHTSA document and evaluate this incident, including whether similar engine-stall, no-start, fuel pump control module, or P069E complaints have been reported for 2014 Chevrolet Impala Limited vehicles outside any previously identified vehicle population.

The contact owns a 2014 Chevrolet Impala. While driving at an undisclosed speed, the Stabili-Trak warning light illuminated and the vehicle lost power steering functionality, causing the steering to become extremely firm. The contact stated that excessive force was needed to turn the steering wheel. The contact safely pulled over, and after the audible alarm ceased, the vehicle returned to normal operation. Additionally, the vehicle lost electrical power and stalled on several occasions. There was no warning light illuminated. While the vehicle was stationary, the vehicle frequently lost power. The contact stated that the battery terminals were disconnected and reconnected after the failure, and the vehicle operated for approximately 15 minutes before the vehicle stalled again. The manufacturer was notified of the failure. The local dealer had inspected the vehicle and confirmed the failure. The dealer had retrieved several unknown fault codes. The vehicle was not yet diagnosed.

The contact owns a 2014 Chevrolet Impala. The contact stated that while driving at an undisclosed speed, the messages "Stabili-trak" and "Power Steering" displayed on the instrument panel, and the traction control warning light illuminated. Additionally, the transmission display switched from drive(D) to park(P) while driving, causing the vehicle to decelerate and stall. The rear-view camera also intermittently failed to function properly, displaying the message "Park Assist Not Available" while reversing. The contact pulled over, waited, and then restarted the vehicle. The contact stated that the wheel hub, camshaft sensor, and a cylinder had previously been replaced, but the failure persisted. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was unknown.
