PURCHASED FROM HENDRICKS IN CARY, NC. NEVER FELT IT OPERATED CORRECTLY, WOULD LURCH FORWARD VERY VIOLENTLY AND BRAKING WAS DIFFICULT. IN EARLY FEB 2015 WHILE DRIVING AT 30-35MPH THE CAR REFUSED TO MOVE FORWARD AND WAS STUCK ON 2ND GEAR, PULLED OVER AND TURNED IT OFF TWICE, BUT WOULD NOT CORRECT. DROVE 6 MILES TO DEALER ON 2ND GEAR, THEY CHECKED IT BUT SENT ME ON MY WAY TELLING ME THAT THEY COULD NOT DUPLICATE IT AND THEREFORE NOT INVESTIGATE. ALSO, THEY TOLD ME THAT THERE WERE NO OTHER SIMILAR COMPLAINTS EVER MADE TO FIAT-CHRYSLER. 2 WKS LATER THE CAR STALLED AND THEN JUST SHUT DOWN IN THE MIDDLE OF AN INTERSECTION, NO TOWING PROVIDED WHEN I CALLED DEALERSHIP, I WAITED FOR MY AAA TO SHOW UP(IN 16 DEGREES)THEY HAD THE CAR FOR OVER 3 WEEKS AND SAID THEY COULDN'T FIND THE PROBLEM. THIS HAS CONTINUED TO HAPPEN, ON 2ND GEAR AND TWICE WHEN I ACCELERATE ON HIGHWAY WONT GO PAST 5TH GEAR AND EVERY TIME I TAKE IT IN AND PICK IT UP, THERE ARE OTHER ISSUES, RADIO, BLUETOOTH,NOT OPERATING, STALLING, LURKING AND BRAKES, ITS LOCKED ME OUT, THERE IS ALSO A VERY FOUL ORDER FROM THE EXHAUST THAT HAS BEEN THERE SINCE THE DAY I TOOK IT HOME. TOTAL DAYS IN SERVICE AT HENDRICKS 71. FILED WITH FIAT-CHRYLSER ON ADVICE FROM DEALER, THEY SAID THEY SUPPORTED THE BUY BACK, BUT WHEN IT CAME DOWN TO DOING IT, THEY REFUSED TO ASSIST. FIAT-CHRYSLER REQUESTED I TAKE IT BACK TO DEALER, THEY HAD IT FOR 36 DAYS. NO ONE CALLS OR COMMUNICATES WITH ME SO I JUST SHOW UP TO GET AN UPDATE AND THE DEALER TELLS ME THERE IS NOTHING WRONG WITH THE CAR, THE BUY BACK HAS BEEN REFUSED AND I NEED TO TAKE MY CAR BACK NOW! WHEN I PICKED UP THE CAR AFTER 36 DAYS IT HAD THE SAME MILES AS WHEN I DROPPED IT OFF. THIS WAS 1 WEEK AGO AND I HAVE YET TO HEAR FROM FIAT-CHRYSLER REGARDING MY REQUEST FOR A BUYBACK OR AT LEAST AN UPDATE ON THEIR INVESTIGATION.

THE VOLUME GOES UP AND DOWN ONCE IN AWHILE BY ITSELF AND THEY CAN'T SEEM TO FIGURE THAT OUT EITHER! ALSO MY WIFE HAS BEEN EXPERIENCING A LACK OF POWER WHEN SHE'S DRIVING AND THE VEHICLE WILL NOT GO PAST 50MPH,AND THEN IT STARTS TO SHAKE PRETTY BAD! SHE HAS TO PULL OVER AND SHUT THE CAR OFF WAIT 2 MINUTES AND THAN TURN IT BACK ON AND THAN IT'S FINE! AND LASTLY WHEN I SIT AT A TRAFFIC LIGHT I START TO SMELL SOMETHING BURNING COMING FROM THE ENGINE AND I PULL OVER TO INSPECT THE ENGINE AND NOTHING.. I CALLED THE DEALERSHIP AND THE LADY TOLD ME IT'S THE TRANSMISSION BURNING BECAUSE I HAVE THE AUTO MANUAL SHIFTER MODEL AND THAT'S WHY IT DOES IT AND IT IS NORMAL! I REALLY DON'T THINK IT'S NORMAL AT ALL? THE LADY AT THE SERVICE COUNTER TOLD ME THAT THIS MODEL REALLY TOOK OFF IN ITALY BUT NOT HERE IN THE STATES! SO I GUESS I BOUGHT A LEMON I TOLD HER AND ALL SHE SAID WAS SHE WAS SORRY!! I HAVE SO MUCH TROUBLE AT THIS DEALERSHIP BECAUSE I HAVE TO PROVE SOMETHING IS ALWAYS WRONG WITH MY CAR!!!

I BOUGHT THIS CAR BRAND NEW IN JUNE 2014 WITH 3 MILES ON IT AND ABSOLUTELY LOVED IT. WHILE SITTING IN A DRIVE THRU ONE DAY, THIS WHITE SMOKE CAME OUT FROM UNDER THE HOOD AND THE SMELL WAS AWFUL. I HAD NO IDEA WHAT WAS GOING ON SINCE NO LIGHT INDICATORS LIT UP ON THE DASH BOARD. I LEFT THE DRIVE THRU AND PROBLEM SEEMED TO STOP SO I THOUGHT NOTHING MORE ABOUT IT. THE OTHER DAY, AGAIN WHILE SITTING IN A DRIVE THRU, WHITE SMOKE POURS OUT FROM UNDER CAR, CAR SHUTTERS, THEN DASH BOARD LIGHTS UP AND CAR DIES. I AM LEFT FREAKING OUT IN A DRIVE THRU ALONE WITH A DEAD SMOKING CAR WHICH HAD TO BE PUSHED OUT BY 2 HELPFUL EMPLOYEES. TOWED TO THE DEALERSHIP, I WAS INFORMED THAT YOU CAN'T JUST SIT IN TRAFFIC WITH THIS CAR, YOU HAVE TO PUSH THE BREAK PEDAL HARD TO RELEASE THE CLUTCH FROM SPINNING AND CAUSING FRICTION. THE FRICTION IN STOP AND GO TRAFFIC WILL CAUSE OVERHEATING AND STALLING OF THE VEHICLE... UM HELLO, THIS IS NOT SAFE. I LIVE IN ORLANDO FLORIDA, STOP AND GO TRAFFIC CAPITAL. I HAVE 8400 MILES ON THIS CAR AND NOW FACED WITH THE DILEMMA OF GETTING RID OF THIS FIRE TRAP WAITING HAPPEN WITH MYSELF AND CHILD IN THE CAR, OR JUST KEEP IT AND PRAY IT DOES DIE IN THE MIDDLE OF THE INTERSTATE AND I AM KILLED TRYING TO PUSH IT OFF THE ROAD. I WILL NEVER BUY THIS BRAND AGAIN, NOR WILL I SUPPORT ANY "FIXES" THEY SAY WILL HELP. THE COMPANY KNOWS THEY MADE A MISTAKE AND COULD COST LIVES, THIS IS WHY IT IS NOT OFFERED IN THE NEW 2015 500L OR THE NEW 2016 500X. I AM GETTING RID OF THIS DEATH TRAP, BUT NOT UNTIL I BUG THE HELL OUT OF THE CORPORATION FOR SELLING FAULTY PRODUCTS TO THE PUBLIC AND KNOWING THE ISSUES AND RISK THEY HAVE CAUSED.

1EA19001 · Electrical Overstress
Opened Apr 19, 2019 · Closed Sep 19, 2024
Status: closed (inferred from source dates) · Air Bags: Air Bag/restraint Control Module
The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect. During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW. The ECU receives signals from crash sensors mounted in the vehicle and deploys the vehicle air bags and seat belt pretensioners in accordance with manufacturer design specifications. The ECU in the subject vehicles contains a model DS84 application-specific integrated circuit (ASIC) which controls the communication of the crash sensor signal, firing commands (i.e., when to deploy the airbag(s) and/or pretensioners), and fault information (e.g., diagnostic trouble codes). In September 2016, FCA announced recall 16V-668 for certain model year (MY) 2010 to 2014 Chrysler, Dodge and Jeep products manufactured with the subject ZF-TRW ACU. In this recall, FCA discussed an EOS condition that resulted in a failure of the subject DS84 ASIC, which caused air bag non-deployment. FCA noted that the defect condition had only been observed in vehicles equipped with sensor harnessing routed across the front of the vehicle. Other FCA vehicles that also used the subject ACU, but were not equipped with cross-car harnessing, had not experienced EOS failures, despite similar time in service. During the course of this investigation, ODI sent two separate Information Request (IR) letters to six vehicle manufactures (including FCA, Hyundai, Honda, Kia, Mitsubishi, and Toyota) and one IR letter to ZF-TRW. These IR letters resulted in ODI receiving comprehensive data from these manufacturers and suppliers. Studies of this data found that the DS84 ASIC does not have sufficient protection against negative electrical transients or electrical overstress (“EOS”) that can be generated in certain severe crashes. An electrical transient occurs when the electrical power supplied to a circuit changes momentarily over a short duration of time. In these severe crash cases, the crash sensors and other powered wiring can be damaged and short circuited so as to create a negative electrical transient of sufficient intensity and duration (that are outside the vehicle manufacturer's specification) to damage the ASIC before the restraint device deployment signal is received by the SRS ECU. This damaged signal can lead to incomplete or nondeployment of the air bags and/or pretensioners. Airbag non-deployment and/or lack of pretensioner operation can increase the risk or severity of injury in a crash.A total of 8 fatalities and 14 injuries were associated with known EOS events. The common element in all investigated manufacturers vehicles is the SRS ECU containing a DS84 ASIC manufactured by ZF-TRW. The risk associated with the ASIC is equally shared among all OEMS involved in the investigation. The actual real-world risk can be mitigated by other factors which were assessed by ODI during this investigation. The first mitigating factor involves protections built into the ACU design which protect the DS84 ASIC from damage. There are multiple strategies and levels of protection employed by different OEMs that provide effective EOS mitigation. The two most common strategies at the ACU level are circuit protection diodes on the remote senor signal lines, and current limiting resistors that protect critical components. The second mitigating factor is found at the vehicle level and involves the location and routing of the wires leading from the crash sensors to the SRS ECU. If the wires are well protected in a crash and are not routed with other power wires carrying large currents, the risk for an EOS event is significantly reduced or eliminated. These design specific factors combine to produce a spectrum of risk for the vehicles equipped with ACUs using the DS84 ASIC. Given the many of years of field exposure, it is possible to divide the subject population into two groups; vehicles which have experienced EOS events, and vehicles which have not experienced EOS field events. Four of the six OEMs involved in this investigation have experienced EOS field events on at least one of their models equipped with a DS84 ASIC. All vehicle models (including the Toyota models identified in the Failure Report Summary of the opening resume for this investigation) with field events have been recalled. In an abundance of caution, ODI kept this investigation open five years to monitor field performance and did not identify any field events on vehicles not included in existing safety recalls. Given the spectrum of risk identified in this investigation and that all vehicles with a demonstrated unreasonable risk have been recalled, ODI is closing this investigation. ODI is closing this investigation with the following manufacturer safety recalls: 16V-668, 18E-043, 18V-137, 18V-363, and 20V-024. With the recall actions taken by the subject vehicle and equipment manufacturers, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exists on other model or model year vehicles outside of the recall scopes. The agency reserves the right to take further action if warranted by the circumstances.
