Good morning my (eps) Electronic steering system isn't working I have the light on my dashboard and while driving it went on and couldn't steer it needs force to turn and its difficult to keep it straight this is the second time im replacing this part last time I had this same problem was 2 yrs ago and I've noticed online people having the same issue with not only challengers but other dodge vehicles that use the Electronic steering system that fails while the car is in motion very dangerous if your driving on the freeway. I seen there was a recall for this but on certain cars but I don't understand why only certain cars this isn't supposed to happen so often and having to be paid off by the owner this is a malfunction or electrical connection thats causing the motor to stop working.

When making a sharp turn where you need to turn the wheel fully to the left or right, the car steering would lock up and a power steering indicator light would appear on the dashboard. I would have to shut the vehicle off and restart it for the light to turn off and resume steering functionality. The car was inspected by the dealership and the indicated that it showed the error code happened one time, however we recently purchased the vehicle with 19,000 miles, so not sure if the happened before we purchased the car and the used car dealer reset the codes. This issue has happened many times over the last 3 months.

MY 17 YEAR OLD SON'S 2016 DODGE CHALLENGER TURNS OFF WHILE CAR IS BEING DRIVEN. THE IGNITION SWITCH USUALLY GOES TO ACC (SOMETIMES RUN). ALSO, THE STEERING WHEEL LOCKS UP, THE HEADLIGHTS GO OUT, BRAKING IS DIFFICULT, HEATING/COOLING TURN OFF, AND ACCORDING TO THE MANUAL THE AIRBAGS BECOME INACTIVE IN ACC. MY SON HAS NEARLY HIT A TREE AND HE HAS CROSSED LANES INTO THE OPPOSITE DIRECTION WHEN THE STEERING WHEEL HAS LOCKED. THE PROBLEM STARTED HAPPENING AT ABOUT 2500 MILES 04/2016. IT HAS HAPPENED FROM10 MPH TO 70 MPH. IT HAS HAPPENED 15 OR MORE TIMES AND SEEMS TO HAPPEN AFTER THE CAR HAS BEEN DRIVEN OVER 20 MILES, PARKED, AND THEN DRIVEN AGAIN. IT HAS HAPPENED ON ALL TYPES OF ROAD--RESIDENTIAL, CITY AND HIGHWAY. IT HAS OCCURRED WHILE BEING DRIVEN STRAIGHT AND WHEN TURNING, ON LEVEL ROADS AND UP HILLS. THE DEALER COULD NOT DUPLICATE THE PROBLEM. THE DEALER CONTACTED CHRYSLER DETROIT WITHOUT SUCCESS. THEY INSTALLED A SPECIAL DATA COLLECTING SWITCH WHICH WE MANUALLY ACTIVATED WHEN THE CAR STALLED. THE DATA WAS FORWARDED TO DETROIT FOR ANALYSIS. I HAVE ATTACHED SERVICE RECORDS. WE HAVE SUPPLIED PHOTOS OF THE INSTRUMENTATION AFTER THE CAR TURNS OFF. MY SON STARTED DRIVING WITH ONE HAND ON HIS IPHONE MAKING A VIDEO RECORDING OF THE CAR STALLING IN LATE SEPTEMBER 2016. THE VIDEO RECORDING IS ON YOUTUBE AT: HTTPS://WWW.YOUTUBE.COM/WATCH?V=SE5TAGU6MY8&FEATURE=YOUTU.BE ON OCTOBER 7, 2016, I MET AT OUR LOCAL DEALERSHIP WITH THE GENERAL MANAGER, SERVICE MANAGER, AND HEAD MECHANIC TO DISCUSS THE PROBLEMS AND TO REVIEW THE VIDEO. THEY STATED THAT THEY DID NOT KNOW HOW TO FIX THE CAR AND HAD TO RELY ON CHRYSLER. THE NEW VIDEO WAS FORWARDED TO CHRYSLER AND A MASTER MECHANIC WAS TO REVIEW IT BUT NOTHING HAS HAPPENED. FURTHER, THEY RECOMMENDED THAT THE CAR SHOULD NOT BE DRIVEN AS IT IS TOO DANGEROUS. SINCE THEN, THE CAR HAS BEEN PARKED. *TR

18V332000 · Electrical System:software; Electrical System:wiring; Vehicle Speed Control:cruise Control

May 17, 2018

Chrysler (FCA US LLC) is recalling certain 2014-2018 Dodge Journey, Charger and Durango, RAM 2500, 3500, 3500 Cab Chassis (more than 10,000lb), 4500 Cab Chassis and 5500 Cab Chassis, Jeep Cherokee and Grand Cherokee and Chrysler 300, 2014-2019 RAM 1500, 2015-2018 Dodge Challenger, 2015-2017 Chrysler 200, 2016-2018 RAM 3500 Cab Chassis (less than 10,000 lb), 2017-2018 Chrysler Pacifica and 2018 Jeep Wrangler vehicles. These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging. If, when using cruise control, there is a short circuit within the vehicle's wiring, the driver may not be able to shut off the cruise control either by depressing the brake pedal or manually turning the system off once it has been engaged, resulting in either the vehicle maintaining its current speed or possibly accelerating.

Consequence & remedy

Consequence: If the vehicle maintains its speed or accelerates despite attempts to deactivate the cruise control, there would be an increased risk of a crash.

Remedy: Chrysler will notify owners, and dealers will inspect the software, and perform a software flash on the engine or powertrain control module, free of charge. The recall began June 4, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Note: Owners are advised to stop using cruise control until the software update has been performed. In the event that cruise control cannot be disengaged while driving, owners should firmly and steadily apply the brakes and shift the transmission to neutral, placing the vehicle in park once it has stopped.

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). This investigation does not supersede EA15-001, which remains open.
