Since the day of delivery, the 2018 Dodge Challenger I purchased from Carvana has been non-operational due to a dead battery and significant engine problems. Despite multiple attempts to start the vehicle, it required towing to the dealer for repairs. Additionally, the car was delivered with illegally dark tint on all windows, including the front windshield, which is not compliant with California state regulations. These issues have rendered the vehicle unusable and have not been adequately addressed, posing safety and compliance concerns

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.

UConnect LCD Control Screen is completely on the fritz due to adhesive de-lamination. The screen will frequently and randomly ‘ghost touch’ itself to turn the heat all the way up, turn the media volume all the way up, call contacts, adjust the clock, switch screens, etc while I’m driving. It is available for inspection upon request. Car has become a danger to drive as a result. Having to constantly fumble with the screen to not be roasted by the heat or have my eardrums blown out by max volume media while driving is significantly more distracting and dangerous than being on the phone while driving. It isn’t something that happens once or twice on a drive, it will touch the screen ~30 times a minute. This is a well known problem with UConnect systems in jeeps and dodges. You can look it up online or speak candidly with any dodge dealer. When I called dealers in my area directly they said this is a problem they see everyday. Vehicle is being taken to be inspected 6 days after reporting this event to UConnect and dodge as that is the earliest appointment they could get me at an approved service center. Absolutely 0 warning this would happen and no functional way to turn off the screen in the meantime. If you try to turn it off, when it senses it touched itself it just turns right back on. I’m being required to pay $300 out of pocket + costs for a rental to get the diagnosis.

Because of this defect the system takes control of the infosystem switching between screens and options and as it gets worse it could possibly get into the power modes and other engine controls by itself without the driver knowing along with taking control of heating, cooling, lights and other safety features on the car itself without the driver knowing. Besides being annoying this is a huge safety concern that they are well aware of as there is extensive back ordering of replacement systems. In the dealership I go to they have 24 replacement units on back order. At roughly $1,800 per unit the company won't take responsibility for this defect.

Per the car fax report provided at time of purchase. This car supposedly not been in any accidents. I noticed that the lights when on are not leveled. I took it to a local Dodge dealer to fix and to my surprise we were told that the lights were not leveled because the car had been in a wreck before. There is no physical damage from what we can see however the cost to repair or level required extra work in order to complete and cost was very high. I feel that Toyota of Aneheim sold us a car knowing it had been in a wreck. When I called to see if they would repair they said no because I cannot prove that the problem existed before we purchased the r car. We have not been on any car accident and feel like Toyota does not care about making things right. Please help https://www.toyotaofanaheim.com

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.
