I experienced an issue with the trunk lights on my 2018 Dodge Charger SXT Plus, which would not illuminate when the trunk was open. Additionally, the dashboard display failed to indicate that the trunk was open. This posed a significant safety concern, as the car allowed me to drive without alerting me that the trunk was open. Normally, when the trunk is ajar, the vehicle displays a notification and prevents the car from being driven without addressing the open trunk. However, with the broken latch, no such alert occurred, and the car could be driven with the trunk accidentally left open. Furthermore, the remote start feature, which typically only works when all doors (including the trunk) are closed, was compromised. The car could be remotely started via the keyfob regardless of whether the trunk was open or closed. This is a serious safety concern, as the vehicle could be driven or left running with the trunk open without the driver’s knowledge. This repair cost $301 to fix. Repair Details: Date of Repair: January 17, 2023 Description of repair from dealership: Trunk lights and dashboard indicator were non-functional, and no alert was provided when the trunk was left open. The latch was internally shorted, causing the malfunction. After the latch was replaced, the lights and notifications worked correctly, and the vehicle's safety functions returned to normal.

The Uconnect screen in my 2018 Dodge Charger SXT Plus began to delaminate, leading to unresponsiveness and phantom touches on the screen. This created a distraction while driving and impacted the use of essential vehicle controls, such as navigation, climate settings, and the backup camera was completely non-functioning. At the dealer I was initially quoted a price over $2,000 and I know from researching the internet many many many others have had this issue. I contacted both Chrysler and a local dealership. The dealership at my 2nd visit replaced the screen for free under a goodwill repair, and Chrysler also contacted me later promised to get the issue resolved if the dealership could not help me. I am reporting this issue because it is a significant defect that could affect the safety and functionality of the vehicle.

The Uconnect system in my vehicle has been delaminating and has been causing several issues in my vehicle where the Blindspot detectors are not working properly and the back up camera is not working properly to notify me and alert me with whistles and chimes if a vehicle is driving behind me while I’m backing up or if a pedestrian is on my Blindspot crossing near my car. The Uconnect system in my vehicle is also causing issues where it is ghost touching and glitching my screen and clicking buttons I’m not clicking. Example trying to change the clock when I’m not clicking anything and when navigation is in, use the system clicks out of maps and starts clicking FM radio. It starts to change stations and put people on hold when I’m on voice connect over the vehicle. It will put someone on mute by itself mostly the fact that the camera is not functioning due to the Uconnect being connected with the vehicle and causing it to malfunction. I’m worried it will start to click on other settings in the vehicle. There are many reports with Dodge Jeep, Chrysler, and ram on all forums about this issue. I’ve notified the Dodge dealership and Uconnect and all the want to do is have me pay out of pocket for a new system that is $2000 not including labor . The uconnect system should be recalled from all vehicles from 2018-2023 .

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.
