Upon starting the vehicle, the service shifter message came on the dashboard screen and all the lights on the shifter illuminated red. If I drive with it on, it stays on. When I turn off the Jeep and turn it back on, the message and lights go off. However, this message has appeared about once a month for the last few months. It is unknown if my safety has been at risk. I've called two different dealers and got widely different answers about what the problem could be, as well as very different cost estimates to fix it. But, no one really knows what the fix is. I've investigated this problem online and have found 100s if not 1000s of complaints about the same problem with no clear solution. Why is there no recall for this yet. It's been going on for years.

At random times, the vehicle will notify of a "Service Shifter" message that pops up on screen. The lights that indicate which gear the car is in all light up-park, neutral, drive, etc. Every light turns on and the notification shows up on the screen where speedometer is located. This is concerning-it has happened multiple times, if I turn the car off and back on, the notification goes away. However, it always comes back a few hundred miles later. I drive a 2017 Jeep Cherokee, and bought it in 2019 with only 16,000 miles on it. The notification first came up when I hit 20,000 miles and has persisted ever since periodically. If you search "Jeep Cherokee service shifter" you can find NUMEROUS forums where people have reported the same issues. It is clearly an issue that needs to be looked into further. I have already filed a safety problem before, and nothing was done about it. I recommend looking into this issue further, and googling the issue as well-there are far too many people reporting the same problem and there has been no recall to be issued.

2017 Jeep Cherokee Latitude 3.2L, V6 Service Bulletin Number: 08-054-18 REV. A Dated September 13, 2018 Group-08 Electrical Code tester detected a failure of the service shifter. A warning light would come on with service shifter error. The failure could cause vehicle to stop and not restart, or it could restart after setting for a while. We had purchased an extended warranty, but our dealership it would not cover the service shifter failure under the warranty. We then took the vehicle to a repair shop, and they said both the shifter harness and bezel needed to be replaced. The mechanic said the part number had been changed for the bezel unit, indicating the part design had been changed from the original. Apparently, Chrysler was aware of the problem, but refused to do a recall. In researching our problem, it seems to be an ongoing problem. Thank goodness we had the problem fixed within a couple of weeks. We could have experienced possible harm if the shifter failed and stalled in traffic or on a busy road. We think a class action claim should be brought against Chrysler for not implementing a recall. We should be reimbursed for our repair by Chrysler. The mechanic removed the defective part and we did not save it. He could provide details if requested. Repair cost $277.31.

The automatic transmission shifter transmits a warning to the instrument panel display with the words SERVICE SHIFTER. All of the red shifter console lights light up at once. The vehicle will not engage the PARK safety brake at times after parking the vehicle when the warning is illuminated. While operating the vehicle no other instrument readings are available (speed, mileage, etc). The vehicle has not yet been inspected by a dealer or mechanic and is a continuing problem. This issue first appeared one month ago and there was no other indication of a problem prior to the first occurrence.

Issue: Burning smell in vehicle. Diagnosis: driver side visor wiring burned, potential fire hazard. Notes: We noticed a burning plastic smell several times in vehicle cabin. I searched around but couldn’t locate the smell. After the third time, the Homelink garage door opener located in the driver’s side sun visor stopped working. Also noted that the vanity mirror lights were not working either. This wiring is not on a fuse. I check the wiring to the visor with a voltmeter and noted 12 bolts to the visor. I removed the passenger visor and plugged it into the driver side. The vanity mirror lights had power and worked. Plugging the driver side visor into the passenger side showed it to not work. Therefore, the issue is the wiring burned inside the visor, breaking the connection. The visor is stitched all around and not easily accessible without cutting and thereby ruining the fabric and appearance of the visor. So wiring is not easily accessible without having to install a new liner.

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.
