Indicator lights are shown on dash include gas cap, seat belt and engine. All gear lights display red when driving and states to service shifter. Dash displays service engine soon. Service air bag system. Seat belt will constantly ding even though it is buckled and will not stop dinging. Replaced gas cap, but indicator light continues to display on dash. Strongly believe there are electrical issues causing theses defects. Took to local dealership and they performed an update, but the indicator lights started to display again the following day, along with the constant dinging from the vehicle not being able to sensor the seat belt being buckled. This has been happening for over a year now and no one seems to be acknowledging there is an extreme safety concern with this vehicle. Strongly believe it is due to the fact of being at fault and not wanting to correct the defects without compensation. Plus there is an abnormal sound when accelerating since these issues began and are continuous. If you’re an attorney reading this, please find me through my vin #. I’m tired of dealing with these issues and willing to take legal action to resolve these issues. Will never buy a Jeep again. Thanks.

My vehicle was in 2 MAJOR wrecks. One in dec 2021, where I t boned someone who turned in front of me at a green light. $19k in damages. Should have totaled it. But how in the hell the air bags didn’t go off is amazing. Bc my chest hit the steering wheel so hard i had to be treated for it. Not only that but the wreck destroyed my lower vertebrae. After it took the shop 6 months to fix and taken back for problems multiple times. I had it 2 weeks, and the brakes failed. Due to something the shop did I’m sure but I rear ended a lady with no brakes at 45-50 mph. Slamming directly into her even though I saw her. I broke my toe I hit the brakes so hard. But again I hit her directly where all the sensors are and this wreck was worse than the first the vehicle totaled and no air bags went off…. I shattered my left knee from hitting the dash.broke my big toe on my right foot etc. why didn’t my air bags go off…… I bought my vehicle certified pre owned in 2019. There’s no way in either wreck I missed that air bag sensor. I work in the collision industry. I know they have to be hit directly on to make them go off but there is no reason mine shouldn’t have other than a defect. I was alone in the first wreck, the second I was further injured and had to stop treatment I was still undergoing from the wreck before bc of the lapsing. My daughter was also injured in the second wreck. Second wreck happened in July 2022

Initially started with parking brake coming on and it took 15 mins of pushing and pulling the button/switch and turning car on and off. Then service air bags light came on. Next was saying passenger and driver seat belts not buckled even tho both were buckled. Then abs light came on. Mechanic determined it was OCR sensor located under center console. Apparently can only get part from jeep and its $400. Ordered and the Jeep wont recognize it so replacement had to be ordered. Now tire pressure light is on as well. Says front driver and rear passenger are low even tho all tires are at 34psi. The seat belt dinging is constant even tho belts are buckled. I have no cruise control. Over past 2 weeks have had the parking brake issue twice. The rest of issues are constant. So now driving around waiting on part with constant worry my parking brake will engage. Other issues are inconvenient and annoying but the brake and airbags are saftey issues. Also my odometer blinks constant too.

1EA21002 · 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.

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).

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.
