My 2016 Jeep Cherokee AWD began showing a “Service 4WD” warning on the dashboard. At the same time the vehicle developed noticeable drivetrain vibration at highway speeds above approximately 55 mph and gears began taking longer than normal to change. A dealership diagnosed the vehicle and found diagnostic code C14A7-97. The technician determined the Power Transfer Unit (PTU) shift motor is binding due to internal wear and that the PTU must be replaced to restore proper four-wheel-drive function. The failure prevents the vehicle from engaging 4WD and causes vibration while driving at highway speeds. The dealer quoted approximately $3,176 to replace the PTU and stated the part is currently on national backorder. This appears similar to the PTU failure addressed in recall 20V343000 affecting other Jeep Cherokee vehicles, but my VIN is not included. Because the symptoms and failure appear identical to the recall condition, I am reporting this as a potential safety defect involving drivetrain failure and vibration during highway driving.My 2016 Jeep Cherokee AWD began showing a “Service 4WD” warning on the dashboard.

I have a 4x4 disengagement warning light and all reviews I have researched say you have to replace the rear transfer case. I bought this car October 2025 111000 miles on it 5 months in I have had to replace a shifter cable, the oil filter housing and now this rear ptu. The srv 4x4 light comes and goes. This could be electrical for poorly made un serviceable parts. I have read and researched miles of threads on this problem. I and many hard working men and women have been affected by these issues. I have never felt this angry about owning a vehicle that is in great shape and is utterly failing to to the lack of mechanically sound products that used in these jeep brand vehicles.

We own a 2016 Jeep Cherokee and have been experiencing ongoing issues with the transmission and acceleration. The vehicle will sometimes hesitate or lag when pressing the gas pedal. There are situations where you try to accelerate and the vehicle does not respond right away. This has created safety concerns while driving. There have been multiple instances where the vehicle did not move as expected when attempting to pull into traffic or accelerate from lower speeds. When you press the accelerator, you expect the vehicle to go, but instead there is a delay or lack of power. This has nearly resulted in accidents due to oncoming traffic. The problem happens most often at normal city / street speeds, especially when accelerating from a stop or at low speeds. The vehicle feels like it struggles to shift or deliver power. We have also noticed hesitation at higher speeds, but the main issue is during everyday driving. No crash has occurred, but the hesitation and inconsistent response make the vehicle feel unsafe and unreliable.

Beginning in late October 2025, my 2016 Jeep Cherokee North Edition began experiencing a recurring electronic shifter and transmission malfunction. The vehicle displays a “Service Shifter” warning (with an A! with a circle arrow and the check engine light is on) and shakes violently upon shifting; it's straight up psychologically unnerving. This issue creates a significant safety hazard because the vehicle may not shift accordingly, consequently increasing the risk of unintended vehicular movement and ultimate loss of control. I previously brought the vehicle to a certified Chrysler/Jeep dealership (Big O’ Dodge Chrysler Jeep, Laurens Rd., Greenville, SC) approximately 13 months earlier for mechanical issues while under warranty. At that time, repairs were completed and I was told no additional mechanical concerns were present. The shifter malfunction began after my extended warranty expired (after 20,000 miles). Since the problem began, I have taken the vehicle to a mechanic multiple times. During each visit, a diagnostic scan tool indicated cylinder misfires: First visit: cylinder #1 misfire — I paid for repairs/replacement. Second visit: cylinder #2 misfire — I paid for additional repairs. Third visit: cylinder #3 misfire — I was advised further repairs would be costly and to consider replacing the vehicle. Despite having recently spent $1,500 on these repairs, the shifting malfunction and safety issues have persisted/have not been resolved. I have been unable to safely operate the vehicle for approximately four months due to the risk associated with the transmission/shifter malfunction. I have learned that similar (2014-2017) Jeep Cherokees have been recalled for similar electronic shifter defects. However, my VIN was not included in the recall. Because this defect poses a serious safety risk and appears consistent with known issues, I am requesting an investigation into this failure. The vehicle is available for inspection upon request.

My Vehicle VIN isn't listed under the massive recall of the PTU (Diagnostic code C14A7-67) Vehicle is the same manufacture year of the recalled vehicles. If the PTU fails it can cause sudden loss of drive power, inability to stay in Park (rollaway risk). The check 4WD light is on and Diagnostic code C14A7-67 comes up. Jeep said my vehicle isn't included in the recall so there isn't anything they can do. I am wondering why this Vin isn't included in the recall and if it should be since it is having the identical issue as the massive recall of similar vehicles. My vehicle lost drive power on a highway and had to carefully glide over to the shoulder.

I was going home, speed limit 55 mph, so thats what I was doing. A suv entering a intersection ahead of me, ( i dont have a stop or yield sign, but they do) the suv never stops, rolling into the intersection, as im entering the intersection at 55 mph. I tried avoidance at last second to no avail. My front drivers corner smashed the middle, passenger side of the other suv. My Jeep continues to the right, uncontrollable, stops in someone's front yard, engine still running. The other car swerved to the left, still on the road, rolling on its side. My airbags never deployed, i didnt even get any lights on the dash, i had to shut the engine off. Not one airbag deployed, and nothing even recognized there was something wrong. This car is supposed to have all options for airbags, yet a collision at highway speed, with post wreck travel of less than 50 feet, and not one single air bag deployed. I very literally could have died right there. I honestly dont know how i didn't.

Chrysler (FCA US LLC) is recalling certain 2014-2017 Jeep Cherokee vehicles equipped with a two-speed Power Transfer Unit (PTU). Relative movement in the Power Transfer Unit (PTU) between the differential input splines and the transmission output shaft may cause some input spline teeth to wear off, which may eventually cause a loss of engagement between the transmission and the differential inside the PTU. If this occurs, power cannot be transferred between the front wheels and the transmission which results in a loss of drive while the vehicle is in motion and a loss of the Park function while stationary.

Consequence & remedy

Consequence: A loss of drive can cause a vehicle crash without prior warning. A loss of the Park function can cause unintended vehicle rollaway which can increase the risk of a crash or injury.

Remedy: FCA US LLC will notify owners, and dealers will perform a software update that will maintain vehicle propulsion by engaging rear wheel drive and prevent rolling in Park by activating the electronic parking brake if a failed input spline occurs. This recall began July 14, 2020. Owners may contact FCA USA LLC customer service at 1-800-853-1403. FCA's number for this recall is W47.

PE22009 · Electronic Parking Brake Water Ingress

Opened Jul 22, 2022 · Closed Oct 29, 2023

Status: closed (inferred from source dates) · Parking Brake:electrical; Parking Brake:electrical:control Module

The Office of Defects Investigation (ODI) opened investigation PE22-009 after having received 80 complaints on model years 2014-2020 Jeep Cherokees alleging the Electronic Parking Brake (EPB) inadvertently activated while the vehicle was in motion.During this investigation, the subject vehicles were updated to include only Model Years (MY) 2014-2016, while MY 2017-2020 were considered peers.Based on related repair invoices, ODI believed the EPB module was damaged by water leaking into the vehicle. When the EPB inadvertently activates, it can cause a stalling condition bringing the vehicle to a stop. ODI was aware of recall 15V-393 that addresses water ingress affecting the power liftgate module on nearly the same population of vehicles subject of this investigation. The liftgate module can potentially catch fire as a result of the water damage. Both the liftgate and EPB modules are located in a similar area of the vehicle. On May 11, 2016, the manufacturer released a Technical Service Bulleting (ODI #10191415, FCA #08-060-16) that instructs dealers on replacing the EPB module and inspecting the electrical connector for corrosion if a customer describes having the EPB not releasing. This Preliminary Evaluation was opened to assess the scope, frequency, and safety-related consequences of the alleged defect. On September 8th, 2022, ODI sent an information request letter to Fiat Chrysler US LLC (FCA) requesting pertinent information on the subject 2014-2016 Jeep Cherokee and Peer 2017-2020 Jeep Cherokee vehicles. FCA Provided its full response on October 27th, 2022 after ODI granted a one-week extension. ODI has reviewed the information FCA provided as well as new reports submitted to NHTSA’s Vehicle Owner Questionnaire database. Based on a review of all available information, ODI has identified evidence supporting a total of 1,655 subject vehicles that likely experienced a failure of the subject EPB. Within the subject vehicle complaints, ODI identified the 2014 Model Year (MY) Jeep Cherokee as having the highest rate of failure, while also being the oldest group of vehicles in this investigation. The 2014 Jeep Cherokees that likely experienced a failure of the subject EPB represent an incident rate of approximately 0.58%. The average Time In Service (TIS) at failure was 2.6 years and the oldest failure occurred at 8.5 years in service. The 2014 population of vehicles is at 9 years in service. All other MY Jeep Cherokee vehicles (both subject and peer) within this investigation had significantly lower failure rates than the 2014 MY Jeep Cherokee. ODI has reviewed all the information available at this time, and identified four allegations of a crash, three allegations of injuries, and one allegation of a fire.Two of the crash allegations alleged injuries, and the alleged injuries were minor severity.All of the alleged injuries appeared to be consistent with hard braking and did not need medical attention. There was no supporting information that demonstrated a fire had occurred on the vehicle. In its response to ODI, FCA provided its assessment of the alleged defect in the subject vehicles, stating that it does not believe the alleged defect poses an unreasonable risk to motor vehicle safety. FCA states the majority of incidents involving the EPB inadvertently activating occurred while the vehicle was stationary and that a small number of incidents occurred while the vehicle was backing up or at low speeds. This is consistent with ODI’s observations. Based on the analysis conducted by ODI, this investigation will be closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. NHTSA reserves the right take additional actions if warranted by future circumstances.

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).
