Back in July of 2025, my vehicle Abruptly Stopped and lost all power on the thruway. Vehicle was towed immediately to local dealership (emerling Jeep in springville ny ), where it then sat for almost 9 months awaiting a safety recall related to the PTU, as was confirmed by dealership. Fast forward to this year, early April 2026, I finally received vehicle back, and was informed a new PTU /software program update had been performed on my 2017 Jeep Cherokee. Upon driving my car off dealership lot, I noticed my inspection sticker had expired, and my vehicle wasn't operating at a normal pace. A constant thud, transmission delay was evident almost immediately. Attempting to finally try and get my vehicle back to its normal condition, I drove to a nearby Mechanic to try and get car inspected. Not even 30min after receiving vehicle back, it started to lose power again. I was luckily able to get to mechanic, and after close inspection of Vehicle, he informed me that my car wasn't safe to drive. The rear differential was now in jeopardy. Mechanic said the constant strain from bad PTU likely damaged my rear differential, and that it needed to get replaced. When I informed emerling of what transpired, they denied my recommendation to drop car back off too them. Haven't responded to several emails asking them to take car back. In my opinion, emerlings lack of care and the need to remove me as quick as possible caused more emotional distress, and I could have gotten into accident on thruway due to their negligence. The reason emerling never preformed inspection, in my opinion, was because they already knew it wouldn't pass, yet still allowed me to leave their lot. That's complete negligence on they're part, and I'm not seeking any type of tangible request. I Merely want the dealership to be held accountable so someone else doesnt go thru what I went thru. Vehicle is now at another dealership awaiting diagnosis, that will then be forwarded to Jeep/Mopar.

My Jeep has been cutting off while driving for the past several months. I've taken it to be serviced several times and everything, from the alternator, engine, fuel pump, battery, etc. are all fine. But the vehicle will cut of while driving or while idling at the traffic light. This is a MAJOR safety hazard. Not only for myself and the occupants of the vehicle but other drivers on the road as well. This could cause serious injury of even death. I have found dozens of reports of the same issues online, and none have identified an issue or recall but this has to be a manufacturer defect. No one should have to drive a car that checks out as "safe" but it an accident waiting to happen, either on the freeway or main roads.

on 11/1/25 we were driving our Jeep and it malfunctioned while at a stop light. We heard a loud "clunk" and the car would barely go and if we tried to put in park, it would continue to roll. We were on top of a hill so thankfully we didnt roll back or into traffic. We could not drive the car and had to have it towed since it was not safe to drive. Our Jeep is at an authorized Jeep dealer since 11/3/25 and we were told the issue was a power transfer unit that would be covered on the recall but the part was on backorder until 12/2. Jeep would only cover $50/day for a car rental, so we had to rely on borrowing cars from others. Once 12/2 came, we reached out to the dealership and they said the part ship date was moved to 12/18! This is not a timely manner. We have made at least 3 calls to Jeep over the past week, and they keep telling us since 12/10/25 that they will let us know in 2 days...2 days pass and they transfer our case. Another two days pass and still no call from them so I called them back and they have yet to call me. We had our Jeep in the week of 11/17 or 11/24 for inspection and it passed. We noticed some lagging when we were going up hills in the 1-2 rpm range but mechanic did not notice it. Between the inspection and when it finally broke down, no lights came on and there were no warning messages. Not until the car broke down on 11/1.

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.

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.
