**randomly at any given speed ** First the radio system will randomly turn off then moments later… stabiliTrak off flashes followed by abs and traction control lights on dash then suddenly my Chevrolet Silverado has a mind of its own ! The door locks will flicker uncontrollably , and the vehicle just suddenly has a loss of power while rpms and gauges are continuously moving while you are unable to even move the vehicle .. this is a ongoing problem since 2019 , that no one seems to have an answer too .. I’ve taken it to 3 different mechanics and still no answers … when it first started happening it was super random and would happen a few times a day but then not happen for months on end then all of the sudden now it is happening several days a week .. I’m currently scared to even drive it which is horrible considering the amount of money I’ve put into this truck .. it has only 100k miles but somehow I am stuck using my dads old truck with 330k miles on it which seems to be more reliable and is 12 years older … sucks to pay over 500$ a month for “ your dream vehicle “ that you can’t even drive or get any real answers to what or where the problem is coming from … seems that thousands of people online have the same problem but yet no one has any solution .. Now that I’ve almost been in 3 serious accidents I decided I have to say something, 2 of these times were over 70 mph on a California freeway !!! Something must be done !

ONE NIGHT ON THE WAY HOME FROM WORK, I WAS DRIVING 60MPH AND ALL OF THE SUDDEN MY TRUCK HYDROPLANED. I MANAGED TO GET THE TRUCK STRAIGHT AND REGAIN CONTROL OF THE VEHICLE. ABOUT A WEEK LATER, AS I'M HEADING HOME ALL OF THE SUDDEN MY ABS, BRAKE, AND TRACTION CONTROL LIGHTS ALL ILLUMINATED. THE DIC READS SERVICE STABILITRAK AND SERVICE TRACTION CONTROL, THEN IT WILL DISPLAY STABILITRAK OFF AND TRACTION CONTROL OFF. I HAD THE CODES READ AND MY TROUBLE CODE WAS P069E - FUEL PUMP CONTROL MODULE REQUESTED MIL ILLUMINATION AND U0073 - CONTROL MODULE COMMUNICATION BUS A OFF. ALL THOSE LIGHTS MENTIONED ABOVE HAVE BEEN ON FOR ABOUT A MONTH. I LOOKED UP INFORMATION ABOUT THE FPCM AND FOUND OUT ABOUT GM RECALL 14515, I ENTERED MY VIN BUT THE ONLY RECALL THAT CAME UP WAS FOR THE TAKATA AIRBAG RECALL. AS I READ THROUGH THE 14515 RECALL, I FEEL MY TRUCK IS AFFECTED BY IT BECAUSE, WHILE DRIVING THE TRUCK MY SPEEDOMETER JUMPS ALL AROUND AND IS NOT STABLE. ALSO, WHEN I TRY TO ACCELERATE, IT FEELS LIKE THE ENGINE STALLS AND THERE'S NO POWER THERE. OTHER TIMES, IT WILL DOWN SHIFT TO INCREASE RPMS, BUT THEN SOON SHIFT GEARS INTO A HIGHER GEAR THEN SHIFT BACK INTO A LOW GEAR AND REPEAT THIS UNTIL I LET OFF THE PEDAL. MY TOW HAUL MODE WILL NOT STAY ENGAGED, CRUISE CONTROL WILL NOT STAY ENGAGED, AND MOST OF THE TIME MY TRUCK WON'T EVEN START WHEN TRYING TO USE THE REMOTE START, INSTEAD LIGHTS JUST FLASH AS I'M HOLDING DOWN THE START BUTTON ON THE KEY FOB. THE TRUCK FEELS REALLY SLUGGISH ALMOST LIKE THERE'S NO POWER, IT SEEMS LIKE IT HUNTS FOR THE RIGHT GEARS WHILE DRIVING. OVERALL IT JUST FEELS UNSAFE TO DRIVE.

ON TUESDAY 10/4/2011 I WAS LEAVING MY PARKING SPACE AT WORK, I HAD MY FOOT ON THE BRAKE AS I WAS TURNING OUT OF THE SPACE, THE VEHICLE JUST TOOK OFF - ACCELERATING WITHOUT TOUCHING THE GAS. I THEN HIT THE BRAKE WHICH STOPPED THE VEHICLE. I THEN GOT ON THE HIGHWAY - (I-94) TO HEAD HOME, WHILE DRIVING ON I-94 MY VEHICLE LUNGED FORWARD NEARLY STRIKING THE VEHICLE IN FRONT OF ME. I THEN BACKED OFF AND KEPT A SAFE DISTANCE IN THE EVENT THAT IT HAPPENED AGAIN, SURE ENOUGH - MY VEHICLE STARTED ACCELERATING ON ITS OWN. I REALIZED IT WAS DOING IT AND HAD ENOUGH DISTANCE BETWEEN ME AND THE OTHER VEHICLES AHEAD, SO I ALLOWED THE VEHICLE TO TAKE OFF. MY SILVERADO GOT UP TO ABOUT 1500 RPMS AT 60MPH, I CLEARLY HAD MY FOOT OFF THE BRAKE AND THE GAS, FEET FLAT ON THE FLOOR. I ALLOWED IT TO ACCELERATE ON ITS OWN FOR APPRX 1 MINUTE BUT THEN HAD TO STOP. IT IS CLEARLY DRIVING ITSELF. I DROVE THE TRUCK STRAIGHT TO THE DEALERSHIP AND LEFT IT FOR THE SHOP TO LOOK AT THE NEXT DAY. THE SERVICE DEPT COULD NOT RE-CREATE THE PROBLEM, GO FIGURE.

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.

EA21002 · Desiccated Air Bag Inflator Rupture

Opened Sep 17, 2021 · No close date supplied

Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata.

Air Bags:frontal:passenger Side:inflator Module

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors.
