Reference service bulletin 20V-343 / W47 Recall Summary (Differential unit) 2 Speed Power Transfer Unit failed (Transfer Case) PTU My wife was driving down the freeway at 65 MPH when the until failed. This was during heavy rains and while the car was hydroplaning. The four wheel drive system kicked in and then the unit failed. She heard a loud clunk and then unit the unit forced itself into neutral. This could have cause the car to spin out of control, but she was able to recover. Wife did not capture error message that occurred during the incident, but it said something about putting the car in neutral. once she was able to stop in the emergency lane on the freeway she came to a complete stop and put the car in park. She was exiting the vehicle and the car started to roll even though the car was in park. She quickly applied the brakes and was able to engage the ebrake. The car is currently at the mechanic for inspection.

1. Consumer is a Permanent and Total Disabled Vet (Unemployable) and this vehicle is the only vehicle Consumer has. 2. I have a 2017 Jeep Cherokee Trailhawk KL (XXX) I have owned since day one with 56k miles. 3. At all times I did not receive any recall notices for correct known safety issues. 5. I have OBD-II tools of vLinker (use everyday for LiveData), BlueDriver and TogDog. 6. For almost as long as I have had the Jeep I have experienced the following. When I say the following I mean, at all times: a. Any type of road- surface- weather- time of day- city, highway and interstate driving- speed to include deaccelerating, at stop sign/light- 1-3 x’s a day, weekly- it doesn’t matter when or where b. The PTU was replaced in 2018 according to service report, service stating they couldn’t replicate issue although they had videos, etc a total of 4-x’s c. But, I keep experiencing the following: d. Loss of acceleration, push on gas pedal nothing happens, sometimes can let off for a bit and then accelerates, revs to 6-7k up/down using/not cruise, cruise doesn’t turn off, pulling trailer and not- lose brakes when stopped rolls back, parking brake message, traction control message, service engine message, loud engine noises from in front of driver, rear back and under center console- lose of rear wheel traction, loss of park- shifting to park grinding noises, 7. Below is a Google Shared Link for anyone that includes videos as it happens, OBD-II scans in .cvs and .brc files along with screenshots of the codes. [XXX] 8. Upon researching these issues I have found 1000s of complaints online regarding the same issues I experience. Including Jeep Compass- Renegade- Wrangler- Grand Cherokee. 9. Upon further research it seems this Consumer is the only one with video during the event and data of said event. 10. I am still retrieving older vids. 11. Vids and documents to large to attach.

Vehicle is putting up a code for “service shifter” while driving, which turns off when the car is turned off. Code does not read for dealerships to fix issue. it is reoccurring and we are concerned as we have seen a 2017 jeep Cherokee wreck out after throwing this code and “locking up the engine”. We are secondhand owners of this jeep and believe the previous owner sold this car because of said issue because it came up within a month of us purchasing the car.

I was driving my 2017 Jeep Cherokee Latitude 2.4L, car won't start, I have oil pressure sensor to warn me when low doesn't alert me at all, only time is when I realized a beep when I made turns and would indicate oil pressure low! I can't get my car to stop and it stalled on me while driving with no indication of low oil, and I have two kids and could have been very bad, since no power no breaks no steering!
When driving my vehicle going 30 miles per hour the car stopped by itself and gave error message “ Shift to park or neutral Press brake or select gear” . I have to put my car in park and try and restart the vehicle. This has happened 4 times with in the last week.

On [XXX] my 2017 Jeep Cherokee Latitude experienced full power failure while driving, resulting in an uncontrolled stopped with lack of power brakes, steering or other electrical assistance while in middle of road with traffic traveling 20 mph just avoiding impact with car in front of me. Had I been on highway or traveling faster I may have encountered a deadly impact to rock walls on road or surrounding traffic or oncoming traffic. There is a recall listed [XXX] Campaign number [XXX]. I have made a complaint to JEEP 800-853-1403 who noted my vin with case number [XXX]. My jeep vin is not included in recall notice but clearly should be and covered for repair under [XXX] . My Jeep regained power 5 min later and I drove it knowing unsafe to repair shop where it sits. My Vin should be added to the already listed appx 67k jeeps 2014-2017 year. I also have MOPAR extended warranty. I will not drive my jeep for obvious reasons until the repair is made. This is a potential deadly issue that needs to be extended to the currant recall listing. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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).

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.
