NHTSA Complaint #11485571 — 2013 FORD MUSTANG

I have a 2013 Ford Mustang V6 coupe with Automatic transmission. I purchased the car Certified Pre Owned through Ken Grody Ford in Carlsbad, CA with Less then ~11,000 miles on it in 2/2014. I have been complaining of a jerk/ knock at ~ 1-1.6 RPM’s when idling & driving in stop and go traffic/ off ramps/ on ramps and parking lots - it appears to come from the transmission area. Fast forward to complaining over the years during service intervals ~ 2x a year for for the works service - oil/ lube/ etc , dealer did a Transmission Control Module computer reset & advised to monitor for symptoms in 11/2020. As covid was present, the car wasn’t driven much during. However the knock/ jerk between 1-1.6 RPM’s has always been present, even returning after the TCM reset. Dealership was notified, and neglected to return calls or follow up. Fast forward to 9/15/2022, after 3-4 wks of calling and leaving voicemails to no avail from the dealership service department manager/ dealership. I set up an appointment for 9/15/2022. On 9/5 & night of 9/14/22, the car instrument cluster lighted up with all notifications, and dashes for the total mileage on the car, orange wrench light - indicating Ford Limp mode, and low fuel popup (car was just fuels 1 hr prior to driving from Costco for grocery) I left and drove up a hill when this occurred as I was going 40-45 miles per hour the speedometer dropped to 0 MPH & the car barely drove beyond 5-15 MPH. I pulled over at the nearest local street from The hill parked the car and powered off the engine. I had a OBDII Tool that indicates: Global OBD FORD. P0720(1 / 1) Output Shaft Speed Sensor Circuit. Severity 2 of 3. I finally heard back from dealer after calling & escalating between 9/15-9/19, once I got ahold of the customer relations managers assistant she said the service manager/ customer relations manager would call back by today 9/20/22. The service mgr states I am out of WTTY & need to cover cost of repair myself. TSB for trans. is attac
