While driving, the car developed a brake malfunction. when the brake pedal is depressed you can feel the pedal pulsating and was not slowing down until you pressed harder then the brakes apply abruptly causing risk of rear ending. Upon pulling over to the hard shoulder the pedal pulsating/drumming continued to happen even though the car is completely stopped and is in parking gear. The symptom is similar to the service bulletin PIC5734A. [XXX] The car was driven to the nearest dealership 'Dublin Chevorlet' in Dublin CA and the car has been there for 4 weeks since GM is unable to help resolve the problem. I have reached out to GM and opened a support case. Case number [XXX] ]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Unfortunately, the engine light is on AGAIN - despite being reset. The car is not accelerating when needed. 2. “Brake Assist” light is on AGAIN- and I do not have power brakes. It is hard to stop. Could we at minimum get accurate warning systems & repairs that work? 2.

Stacia was driving the vehicle on September 20th on a residential street. She was driving at 25 MPH. All of the sudden the brakes slammed on by themselves and the car slammed to a stop. Luckily there were not any cars around, or there would have certainly been an accident. If this had happened on the Interstate or on a busy street there likely would have been a serious accident. The vehicle was taken for service and it was determined that the Brake Pedal Position Sensor failed. This was replaced by Eric Von Schledorn Chevrolet. Our concern is that the failure of one sensor could cause a potential catastrophic accident. We wanted to bring this to your attention in case others have had a similar issue, and a recall may be necessary.

2DP22005 · Pedestrian Alert Sounds
Opened Jan 27, 2023 · Closed Aug 7, 2023
Status: closed (inferred from source dates) · Electrical System:propulsion System
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
PE19013 · Passenger Sensing System
Opened Sep 17, 2019 · Closed Jul 2, 2021
Status: closed (inferred from source dates) · Air Bags:sensor:occupant Classification:front Passenger
In September 2019, the Office of Defects Investigation (ODI) opened PE19-013 to assess the potential safety related effects of a malfunction of the Passenger Sensing System (PSS) in 2012-2013 Model Year (MY) Chevrolet Volt vehicles. Consumers reported that due to a malfunction of the PSS, the air bag system malfunction indicator light (MIL) was activated. Many of the complaints noted the malfunction occurred after the warranty period expired and mentioned high repair costs as a major deterrent to the repair of the vehicle.The PSS sensor mat is embedded in the front passenger seat cushion and is intended to detect child seats and small statured occupants who could be harmed by deployment of the frontal passenger air bag. The PSS may develop a malfunction due to bunching of the sensor mat in the seat trench. The bunching of the sensor mat could cause the mat to repeatedly fold in the same location. Over time, the repeated folding can cause an increased resistance in the sensor mat. An increased resistance in the PSS sensor mat is detected as a fault in the air bag system diagnostic. If this fault is detected, a diagnostic trouble code will be stored in the air bag control unit and the air bag MIL will illuminate.Further, if the fault is detected, the passenger frontal and knee air bags will be suppressed in a crash of sufficient severity to warrant a commanded deployment regardless of the nature of size of the occupant of the front passenger seat.The report counts shown above include only those reports that specifically address the issue covered by this investigation, failure of the PSS sensor mat. Reports alleging only that the air bag light is on with no cause stated, or where a different cause was otherwise identified, were excluded as the air bag light could be illuminated for system faults other than a PSS malfunction.The subject vehicles have been in service for approximately ten (10) years. An analysis of General Motors (GM) warranty data for the subject vehicles, including a comparison with other agency and manufacturer data pertaining to similar occupant detection system failure investigations, indicates the subject vehicles experience a comparatively low complaint rate for this issue given the number of years the vehicles have been in service.GM has instituted a cost reduction program for the repair/replacement of the PSS in the subject vehicles. Based on this cost reduction program as well as:1) a comparatively low warranty rate; 2) no reported injuries, deaths or asymmetric deployments; and 3) the age of the vehicles; ODI is closing this Preliminary Evaluation. The closing of this investigation does not constitute a finding by NHTSA that a safety related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.The ODI complaints cited above can be viewed at www.nhtsa.gov under the following ODI identification numbers in a separate attachment.
