Uconnect screen is delaminating. It’s causing safety hazards due to driver distraction because of the radio volume randomly going full blast ( scaring me half to death) , heat turns itself up all the way full blast ( that’s very dangerous especially when you have little kids in the car), it will switch to the back up cam while driving ( scaring the crap out me me at times) randomly placing calls when Bluetooth is active, the list can go on. It will literally look like someone is touching the screen pressing on stuff, although no one is touching it. It’s almost caused me to get in several accidents from being distracted which this. I contacted Uconnect when this first started to happen and the said I was out of my 36,000 mile warranty ( I had 38,000 miles) and the couldn’t help me. It’s only getting worse

The uConnect 8.4 Display in my car has begun to delaminate. There is a large air pocket under the top portion of my display. This morning while waiting for the car to warm up so the heat would function on the climate control system, I used the display to set the defrost to on. After removing the initial frost from my windshield and I was able to see clearly, I left the house and headed to work. While on my way to work I begun to hear confirmation beeps from my display, as if I was touching the onscreen controls. The touchscreen display began to change settings on its own. Changing my climate controls from High heat to low Cold resulting in my windshield immediately frosting up and reducing my visibility to nothing, during morning traffic. I nearly impacted another vehicle that was turning while distracted by the display and the lack of visibility it caused. I rolled down the windows and found a safe place to pull over to wipe the frost from my windshield. The entire time the display was switching thru pages and begun to call contacts from my phone change songs, and even the performance level settings. I had taken the vehicle to the dealership far prior to my warranty expiring when I initially noticed the bubble at the top of my screen, only to be told that since it was a cosmetic defect and the operation was normal that the warranty would not cover the replacement. and a replacement was $2,200. Now my vehicle warranty is expired and it has changed from a cosmetic defect to a defect that has affected the safe operation and nearly caused me to rear end another vehicle at 55 MPH. From the research I have gathered during my lunch break the display in these units operates too hot and the glue bonding the touch panel to the display itself has melted and caused the separation. It seems to be a common issue that affects any vehicle with a 8.4 uConnect display, judging by complaints on the forums. This is not only a distraction but a Major safety hazard.

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.
