Shift Linkage/cable/rod problems of the 2015 Dodge Dart

My 2015 Dart has suffered a major loss of shift function, the key is being trapped in the ignition, the gears are not shifting properly or sometimes the gear locks up and doesn’t shift at all. The dealer refused repair due to parts not being available. I have been in contact with the dealership on numerous occasions by phone and told I have to wait until the parts become available in the past and recently with the manufacturer (NHTSA) and nothing has been done about the issue. The car is unsafe for me to drive the car has slipped into neutral while I was driving. The car is available for inspection upon request. The problem was confirmed prior to this incident on a previous recall but the issue is happening again after being repaired for the initial problem and it has been a hassle with customer service on how to get a resolution before tragedy happens driving the vehicle with these problems. There were not other symptoms of the problem prior to failure.

Recall on parts not available tried several times to get appointment no parts. This I and 1 car family must use daily to work and and cannot get fixed per dealership no parts available 2+ years or so. Need help for this severe issue as a consumer. Who is responsible if collision or death from this.

Due to this safety-related defect, the vehicle moves even when the car is placed in park and on other occasions this defect has prevented the car from starting. I feel completely unsafe, but do not have another option for transportation. I am a senior on a fixed income so I can not purchase a new vehicle. I have taken excellent care of my Dodge Dart because I know I can't buy another car; but I need the manufacturer to care enough to fix this for me and many others. These incidents have occurred several times but the most recent is indicated below.

The contact owns a 2015 Dodge Dart. The contact received notification of NHTSA campaign number: 25v674000 (power train); however, the part for the repair was unavailable. The contact stated the manufacturer had exceeded a reasonable amount of time for the remedy to be available. The dealer was contacted, and it was confirmed that the remedy was not available. The contact stated that while in park, the transmission would shift, causing the vehicle to move slightly forward. While driving at various speeds, the vehicle would suddenly slow and come to a complete stop. The contact would have to immediately turn the vehicle off, then restart. When restarting the vehicle, it would fail to start immediately, intermittently, requiring several attempts. The manufacturer was made aware of the issue, and a case was opened. The failure mileage was approximately 110,000.
