NHTSA Complaint #11475295 — 2012 FORD FOCUS

I had regular service done on my vehicle 5/27/2022 to which the battery needed to be replaced. That was done without issue however 3 days later as I was on my way to work the check engine light came on and my engine began revving then stalling/losing power as well as shuddering. This was especially concerning as I was on the highway traveling at 70 MPH when suddenly I lost engine power and my vehicle began lurching. I was close enough to home that I was able to turn back and drive very slowly as it was apparent there was an issue in the gears turning over when accelerating. I could not get my vehicle in for service as the dealership could only schedule me later the following week to get it diagnosed. I was able to drive it, again very, very slowly - to the dealership. I was told it was the TCM; 14MO2 Extended Coverage Warranty. The dealership assured me this would be covered yet now continues to tell me that this is not being accepted and that I have to pay out of pocket for this repair. I'm unsure of what to do at this point as my daily commuter has been at the dealership since June 9th 2022.
