NHTSA Complaint #11702683 — 2017 JEEP CHEROKEE

My car back in June 2025 left me stranded in the turn lane with traffic backing up after the emergency parking brake turned on without warning. I was not able to drive e my car or to release the brake and move my car. I did a thorough review of all possible reasonable switches that could have caused the malfunction. So I tried to turn off all of the warning systems. Once I did this I couldn't drive faster than 5 to 10 mph. I was able to get to a parking lot about 100 ft away. I called a tow truck, spoke with my mechanic at the local dealership. He suggested what I had already done including removing the battery cables. We did all this to no avail. He got the car then took 3 days to get it to release after opening and closing the door 10 times before starting the car again. He said I need a modulator valve. We have been waiting for over 6 months and my car is still waiting for this part. I can not drive the only car I own when I have a safety issue. Should this had happened while driving with my grandson in the car it is unsafe and it isn't what an autistic child needs to face. This incident has happened 4 times since it happened in June. Every time it takes place, I have to turn off the car open and close the door 10 times before the carvwill release and reset the computer system to make the car drivable again. I did check with the dealership yesterday and still other jeeps of this year has the same issues but my car is not in that listing. What does a person have do when it is clearly a manufacturer defect?
