The Uconnect HMI/touchscreen in my 2018 Dodge Challenger has visibly delaminated and developed severe phantom touch inputs. When powered on, the screen registers commands without any physical contact. The failed touchscreen remains installed and available for inspection. The vehicle has approximately 19,600 miles. This creates a significant driver distraction and safety risk while driving because the touchscreen repeatedly activates functions and changes settings without my input, including HVAC controls, fan speed, camera activation, audio sources/stations, menus, and other touchscreen-controlled features. Because the system is actively issuing unintended commands, I must look away from the road to determine what changed and try to correct it. Additional phantom inputs repeatedly occur immediately afterward, forcing repeated attention to the screen and diverting focus from traffic, road conditions, pedestrians, cyclists, and other hazards. The ongoing, unpredictable malfunction increases crash risk. The safety concern is not that the infotainment system is inoperative; it is that the touchscreen actively generates unintended inputs while driving, creating a recurring distraction that cannot be safely anticipated or ignored. I previously brought the vehicle to a Dodge dealer for this issue. The dealer instructed me to contact Uconnect/Dodge Customer Care, though I do not know whether the condition was formally documented. Dodge Customer Care opened Case #97977966 and instructed me to return to the dealer for further diagnosis, which I intend to do. There were no warning lamps or messages before the failure. The first symptom was visible delamination, which progressed to phantom touchscreen activity. The condition is now present whenever the HMI is powered on. The touchscreen has not been repaired or replaced and remains available for inspection.

Driving along and all of a sudden the shifter lights started flashing, wipers turned on, steering became difficult, and finally the transmission locked up. Stalled in the middle of the hiway turn lane and because the transmission was locked up it couldn't even be pushed out of the way. Traffic was backed up and people trying to get around because I was blocking a major hiway intersection. The dodge dealership has had the car 3 times and finally diagnosed it as the rack and pinion plug.

I purchased the vehicle which had minor passenger door damage under $500. There were false reports on Copart and Autobidmaster about the vehicle. They lied and said the vehicle was 91.2 percent damaged. The businesses are false. They admitted insanity as their fraudulent motivation. The title should be clean title and the door has been completely repaired. The title to the vehicle should be in my name. Car is ready to be registered. The reports from State Farm Insurance, Copart and Autobidmaster were what they said were false attempts to keep me from registering my vehicle I purchased. This has been ongoing since February 2025 and they are the guilty party.

My trouble is with my 2018 Dodge Challenger. The UConnect system is delaminating and the entire system is malfunctioning. I have taken the vehicle to my local Dodge dealer and showed them the issue, and they agree there is an issue. The safety issue is that the screen display system goes into what is called "ghost touching" where random buttons on the display are acting as if someone is pushing them but no one is touching anything. While backing up, the screen goes haywire, when trying to control anything electronic, the system goes haywire. Safety issue of distraction trying to find certain when in "ghost mode" The vehicle has been inspected by my local Dodge dealer, and agree there is an issue, but refuse to fix it without me paying $1,500. No prior issues electrically prior to the delamination issue. The first time is saw an issue was june 0f 2024.

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.
