Head lights become inoperable. Dealer says its a common problem. $1,500 fix. Well known power issue. Heavily discuss on the internet. Temp fix is to replace fuses that ARE NOT BLOWN. They are melting in place causing non contact. I have never seen a fuse melt and not blow. Potential dangerous situation especially if you have the owners replacing with a higher rated fuse then what is called for. The manufacturer has 20 amp mini fuses in position 15 & 16 to protect the two circuits. One for each headlamp.

My screen is delaminating and posing a risk for backing up and using the rear view camera. I am unable to use navigation which causes me to make wrong turns and struggle to get where I’m going as I have to hold my phone for navigation. This is very stressful as the screen touches things by itself. It makes calls during my drive so I struggle to end them before going through.

Engine: Timing chain, valve rocker arms and valve lifters. All in sequence once the rocker arms went out with the lifters which is a common problem with dodge 3.6L PenStar engine it made my timing chain go off timing causing my engine to shut off while driving. Lighting: When vehicle was purchased i noticed condensation in both head lights got 1 replaced per warranty, they would not do both at same time and within 1 month moisture was in replaced headlight again. Dodge would not replace headlights even though the malfunction was not due to any wear and tear of mine. This is extremely unsafe for drivers if both headlights go out due to extreme amounts of condensation/moisture.

The electric steering rack failed. I was turning into a parking lot and suddenly there was no power steering. Luckily I had both hands on the wheel and was able to avoid an accident. A dash light came on at that time related to steering. My mechanic was able to pull the code. I was able to drive home. What component or system failed or malfunctioned, and is it available for inspection upon request? I have the EPS unit right now - but it is a Core and I have 14 days to return. Please let me know ASAP if you want me to keep it. How was your safety or the safety of others put at risk? Sudden loss of power steering without advanced notice. Old cars with power steering often make a "noise" prior to failure. Electric Power Steering like on my car doesn't provide advanced notice of issues. Also, failures of power steering at 57K miles are rare. But Dodge (Chrysler) have had prior NHTSA issues and recalls prior with EPS. Also, it seems like this may be a common issue - as there are almost no new parts available, no reman/aftermarket parts, and very difficult to find used. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No - out of warranty Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Nothing prior - but warning light after EPS failure.

The radio screen is delaminating (Common problem with many Dodge owners). The screen can no longer be controlled to use hands free phone which is critical for my job and soon to be a new law in Michigan. Radio "ghost dials" different stations. Cannot control the climate control etc. Car is out of warranty, but I believe should be repaired at no cost because I have read many complaints about the same problem. I also saw websites like Top Class Actions and ClassAction.org that were inquiring information about similar issues on several Chrysler products from I believe 2017 - 2020? This does become a safety issue and wanted you to be aware of this. Our problem started in early 2022 and has continued to get worse.

The control touch screen has delaminated. The radio and the vehicle operation functions will not work most of the time. The screen is also apparently sensing input and randomly initiates functions so it beeps, changes stations, adjusts heating/cooling, etc. This is very distracting and I'm concerned that at some point all of these functions will become inaccessible. The car has 5,000 miles, is barely over 3 years old and neither the dealership nor Chrysler will take responsibility. I see this issue is very common. The cost of the radio is over $2,000 and Chrysler will not confirm if the replacement is the same version that came with the car - if so, should I expect to pay another $2,000 in 3 years?!?

The screen cover separates from the touch screen on the radio. This makes the radio not function but more importantly other vehicle operational features are inaccessible. Apparently the screen feels random touches so even when I power it down it turns itself back on constantly beeping changinging stations, adjusting the heating/cooling controls, the clock etc. This is very distracting to a driver and I did nothing unusual to this device. I contacted the dealership and just the screen alone is over $1000. Before I pay this I wonder if anyone else has had similar issues or if its been previously addressed.

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.

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.
