THE BRAKE ANTILOCK WHEEL SPEED SENSORS ON THE FRONT WHEELS LOCKED INTO SKID MODE AND MY CAR WOULD NOT GO OVER 4 MILES AN HOUR. WHEN I LEFT THE DEALERSHIP AND PULLED OUT ON TO THE MAIN ROAD I COULD NOT GO OVER 4 MILES AN HOUR. I WAS ALMOST REAR ENDED SINCE THE SPEED LIMIT ON THE ROAD WAS 40 MPH. I WAS TOLD THE SENSORS WERE BAD AND NEEDED TO BE REPLACED. WHEN I LIMPED THE CAR BACK INTO THE DEALERSHIP, THEY TOLD ME THAT THEY COULD NOT GET THE CAR OUT OF THAT MODE UNTIL THEY REPLACED THE SENSORS. THE CAR ONLY HAS 7200 MILES ON IT.

4 JULY 2017, WHILE DRIVING AT HIGHWAY SPEEDS, VEHICLE FAULT INDICATORS SHOWING PROBLEM WITH STABILITY CONTROL SYSTEM, ABS SYSTEM, AND DISABLED CRUISE CONTROL. FAULTS CLEARED APPROXIMATELY 30 SECONDS LATER. 5 JULY 2017, VEHICLE AGAIN DISPLAYED SAME FAULTS, HOWEVER, FAULTS REMAINED LATCHED (DID NOT SELF CLEAR). I CONTACTED LOCAL DEALERSHIP FOR SERVICE, FAULT WAS DIAGNOSED ON 6 JULY 2017 AS A FAILED RIGHT FRONT WHEEL SPEED SENSOR. SERVICE DEPARTMENT PLACED NEEDED PART ON ORDER, RETURNED KEYS TO ME AND ARRANGEMENTS WERE MADE TO BRING VEHICLE BACK TO DEALERSHIP FOR REPAIR ON 7 JULY 2017. WHILE CONTINUING ON TO PLACE OF WORK, FAULTS RETURNED, THEN CLEARED. AT THE END OF DAY, 6 JULY, WAS APPROACHING A STOP SIGN AT NORMAL APPROACH SPEEDS AND APPLIED BRAKES. FRONT BRAKES INITIALLY OPERATED AS NORMAL, THEN WITHIN A SECOND OR SO, LOST BRAKE PRESSURE...I FELT THE ABS SYSTEM RELEASE THE BRAKES, CAUSING ME TO EXERT ENORMOUS PRESSURE ON THE BRAKE PEDAL WITHIN A FEW FEET OF THE STOP SIGN TO GET THE VEHICLE STOPPED FROM ONLY A FEW MPH. ONCOMING TRAFFIC WAS 55 MPH. AFTER THE VEHICLE STOPPED (BARELY)..THEN THE SAME FAULTS APPEARED. FROM MY POINT OF VIEW, THE INTERMITTENT WHEEL SPEED SENSOR CAUSED THE FRONT ABS SYSTEM TO ACTIVATE ON A DRY ROAD, ESSENTIALLY DISABLING MY FRONT BRAKES WHILE IN THE PROCESS OF BRAKING. THIS IS NOT AN EXPECTED FAILURE MODE. I UNDERSTAND ONBOARD DIAGNOSTICS INDICATING THE PROBLEMS ABOVE, HOWEVER, IT APPEARS THAT IF THIS PROBLEM TAKES PLACE WHILE BRAKING, BRAKE PERFORMANCE IS COMPROMISED. THIS IS NOW THE SECOND WHEEL SPEED SENSOR TO BE REPLACED IN THE LAST 6 MONTHS OR SO. FROM MY PERSPECTIVE, THAT MEANS THAT THIS IS A HIGH FAILURE RATE ITEM (LAST ONE WAS ON THE RIGHT REAR WHEEL), AND IF IT HAPPENS WHILE BRAKING...I ESSENTIALLY LOSE BRAKING AT THE PRECISE MOMENT BRAKES ARE NEEDED. I CONSIDER THIS A DESIGN ISSUE. REDUNDANT SENSORS RECOMMENDED FOR ABS.

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.

RQ15004 · Software Security Vulnerability

Opened Jul 24, 2015 · Closed Jan 5, 2016

Status: closed (inferred from source dates) · Electrical System:software

On July 23, 2015, Fiat Chrysler Automobiles (FCA) launched Safety Recall 15V-461 to remedy security vulnerabilities in approximately 1.4 million model year (MY) 2013 through 2015 vehicles equipped with Uconnect head units (HU) 8.4A (RA3 radio) and 8.4AN (RA4 radio) manufactured by Harman International.On July 24, 2015, the Office of Defects Investigation (ODI) opened Recall Query, RQ 15-004, to investigate HU security vulnerabilities and remedy effectiveness in the recalled population and to determine whether similar units have been supplied for use in other FCA vehicles.In an August 11, 2015 letter, FCA submitted a second Part 573 safety recall report expanding the scope of the Uconnect RA4 model radio to include additional 7,810 MY 2015 Jeep Renegade vehicles manufactured from September 18, 2014 through June 25, 2015 (Recall 15V-508).Scope analysis indicated that Uconnect radios installed in FCA vehicles not included in recalls 15V-461 or 15V-508 (subject recalls) are not equipped with built-in cellular access or short range wireless communication features and, thus, do not contain the security vulnerabilities addressed by the subject recalls. SUBJECT VEHICLES: MY2014 through 2015 Dodge Durango, Jeep Grand Cherokee and Jeep Cherokee sport utility vehicles; MY2013 through 2015 Ram 1500, 2500, 3500 and 4500/5500 pickup trucks; MY2013 through 2015 Dodge Viper vehicles; and MY2015 Chrysler 200, 300, Jeep Renegade, Dodge Charger and Challenger vehicles.According to FCA, long and short range wireless vulnerabilities identified in the recalled vehicles could allow unauthorized third-party access to, and manipulation of, networked vehicle control systems.Successful exploitation of the vulnerabilities, coupled with reverse engineering of networked microprocessor control modules, could result in unauthorized manipulation of vehicle control systems. This unauthorized manipulation of vehicle controls and systems could expose the driver, vehicle occupants or other highway users to an increased risk of injury.FCA and its network provider, Sprint, conducted a nationwide campaign to block access to a radio communications port that was unintentionally left open.On July 27, 2015, short range wireless vulnerabilities were also blocked.Finally, third party security evaluation and regression testing identified vulnerabilities that were either remedied by Sprint or through updates to the FCA Uconnect software.ODI identified a total of 30 complaints or field reports on unique vehicles submitted by FCA (29) or received by NHTSA (1) alleging incidents of theft from a vehicle or anomalous performance that the owner alleged were caused by, or may have been caused by, remote hacking.Twenty-six (87%) of these reports were submitted after a magazine article was published on July 21, 2015, describing the remote hacking of an FCA vehicle by researchers who were able to affect the operation of various vehicle control systems, including the service brakes, steering, throttle and ignition.Most of the complaints involved vehicle systems that were not safety critical (e.g., complaints related to radio, navigation system, or air-conditioning control) and did not affect vehicle control.Three complaints reported engine stalls.One owner reported sudden unintended acceleration allegedly related to hacking.None of the complaints or field reports reviewed involved the steering and braking vehicle control effects demonstrated by the research hackers prior to the recall.There were no confirmed incidents of hacking in any of the records reviewed by ODI.The remedies completed by Sprint and FCA appear to have eliminated vulnerabilities that mi
