2022 Nissan Murano

My wife was victim to a hit and run driver on 30 Dec 22. Our 2022 Nissan Murano's AUTOMATIC COLLISION NOTIFICATION SYSTEM FAILED TO ACTIVATE UPON COLLISION. There were no warnings in the car prior. Additionally, the secondary system known as the "SOS BUTTON" which My Wife manually activated REPEATEDLY for 15 minutes failed. She called 911 and after 45 minutes a trooper finally arrived to help her. Unbelievably, this manufacturer advised us to "routinely test" the system to ensure it is active!!! No explanation how (we press the SOS button each time we start the vehicle now, and feel afraid to drive it, (but we have no other option). Nissan has not reached out to us until recently to express their denial of the system failure (this system failure has already been verified by two separate Nissan agents where three separate reported failures occurred that same day PRIOR to the accident). We were not notified. Our request to Fred Anderson Nissan and the manufacturer for a "buy back" were denied. I'm a 100% disabled Veteran (Retiree) and my wife is also a disabled Veteran (Retiree). One year ago we put our ENTIRE LIFE SAVINGS of $22,000.00 down-payment on the Murano,as it offered the most safety features available, specifically the Automatic Collision Notification system, which is to notify a specially trained agent to initiate emergency services. This system is a major priority for us. The dealership's only response is to trade the vehicle in (lose our $22,000.00 in the process) and purchase another Nissan with the same system in place. Our new vehicle has depreciated almost 40% in less than one year. We're being forced by the manufacturer to either keep this car with documented safety failures, or sacrifice our life Savings and begin anew with another 6 year payment, with zero equity. we have just begun to travel in this "perfect vehicle", after serving a combined 60 years of service to our country. Our financial future is at stake, and we did nothing to cause this.
