Rear backup camera will sometimes either be distorted or have a black screen while in reverse. This is a safety hazard as dodge challengers have large blind spots and makes it difficult to see when backing up without the rear camera. This has almost caused me to hit another car and pedestrians as it's hard to see them due to the blind spots and not having the assistance of the camera. While driving in the rain, the front windshield will have streaks across the whole window, making it very difficult to see while driving in the rain. Windshield wipers have been replaced several times but issue continues to happen. The breaks will shake when breaking. This causes the car to not want to break at times. I have brought my car back to the dealership on several different occasions for this issue and all they have done is resurfaced the rotors and have changed the break pads and told me that there is nothing else they can do and to break more aggressively as there is a film on the rotors causing the car to shake when breaking.

I WAS IN THE CITY OF OLD SAN JUAN, IN MOTION DRIVING DOWN A TWO LANE STREET. I WAS IN A STRAIGHT WAY I HAD BEEN PRESSING THE BRAKE DOWN TO 55 MILES APPROACHING A A SLIGHT CURVE ( NOT EVEN HARD, THE CURVE ONLY DEVIATED FEW FEET TO A RIGHT AND THEN A COUPLE FEET TO LEFT, IN PR TRAVELING TO THE IN THE HISTORICAL AREA THERE IS A CEMENT LIKE STRUCTURE NO MORE THAN 10 INCHES SERVING AS A BARRIER BETWEEN THE TWO CAR LANES AND THE BICYCLE PATH). AT THAT MOMENT I LOST CONTROL OF THE VEHICLE, BRAKES FELT WEIRD COMPLETELY PRESSING THEM DOWN, IN MOTION. WHEN I SLIGHTLY PUMP THE BRAKE AGAIN GOING TOWARD A FULL PRESS THE BRAKE AND WHEELS DIDN'T RESPOND. I TRIED GETTING CONTROL AND AS I LEFT THE LAST CORNER AND STEER I LOST CONTROL HITTING THE BARRIER. MY FRONT TIRE WENT OFF!! ROLLED DOWN HILL. AFTER THAT MY CAR GOT SCRATCH AT THE BOTTOM DRIVING ON MY BRAKE PAD. I BOUGHT THE CAR THE SAME DAY!!!!! I CAN'T STRESS ENOUGH THE SITUATION. I USED TO DRIVE OLDER MODELS AND I'VE NEVER HAD THIS ENCOUNTER. THE STREET THAT IT HAPPEN WAS ASPHALT. THE DEALER AND BANK I GOT MY LOAN, DENIED MY CIVIL CODE RIGHTS, HAD TO GO THROUGH THE INSURANCE. I DIDN'T SIGN THE DOCUMENT STATING I GAVE THE RIGHTS TO THE CAR. THE DEALER INDEPENDENT DODGE DEALER TOOK BACK THE CAR AND NEVER COMPENSATED ME NOR DEALT WITH ME AGAIN. THEY NEVER GAVE ME AN ALTERNATE VEHICLE FOR MY TROUBLE WHILE I FIXED THE PROBLEM. THEY NEVER CALLED BACK! I TRIED GETTING A GOOD LAWYER BUT AFTER THEY TESTED WHAT HAPPEN IN THE BLACK BOX THEY GOT TO THE CONCLUSION I WAS 40 MPH, 5 SECONDS, PRIOR TO THE MOMENT THE INCIDENT TOOK PLACE, SO I WASN'T GOING THAT FAST PUSHING MY BRAKES LOSING CONTROL FROM THE LEFT LANE TOWARDS THE CONCRETE I COULDN'T GET A LAWYER IN PUERTO RICO. I FELT THEY STOLE MY HARD EARNED MONEY, $5,000 I PAID UPFRONT, PLUS THE LOAN AND PLUS THE INSURANCE MONEY AND THE LAWYER I HAD TO PAY FOR THE AGGRAVATION.

SHE CLOSED THE CASE AND SENT ME NO NOTICE. THE TRANSMISSION ALSO HAS SHIFTING ISSUES AND BANGS IN AND OUT OF GEAR AT LOW OR HIGH SPEEDS AT ALL TIMES, WHEN THE CAR HAS BEEN, OR HAS NOT BEEN DRIVEN. I HAVE LEASED OR BOUGHT 7 CARS FROM CHRYSLER / DODGE IN THE LAST TEN YEARS AND HAVE NEVER BEEN TREATED SO POORLY. I DID ASK THAT THEY TAKE THE CAR BACK AS THE FIRST INCIDENT OCCURRED WITHIN 3K MILES WHERE I NEARLY RE-ENDED SOMEONE AT VERY LOW SPEEDS UNDER 20 MPH BECAUSE OF THE CAR'S DEFECTIVE STOPPING DISTANCE. INSTEAD DODGE TOLD ME TO GO THROUGH MY STATE'S LEMON LAW. I AM ASKING FOR ASSISTANCE FROM THE NHTSA. I AM ASKING THAT THEY CONTACT DODGE FCA CUSTOMER CARE DIRECTLY AT 1 844 827 2006 AND SPEAK TO SARAH AT EXTENSION 3020683. THE TRANSMISSION IS VERY CLUNKY AS WELL. IT SLAMS INTO A LOWER GEAR SO HARD IT LURCHES THE VEHICLE BACKWARDS FROM THIRD TO SECOND GEAR.

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.
