Your car won't start and is displaying a diagnostic code (P1327) that was specifically mentioned in a recall letter you received in April 2025. Your original dealership initially said the engine needed replacement but later cleared the recall after a software update, even though the same error code is now preventing your car from starting almost a year later with an expired warranty. The current dealership is refusing to help because you didn't purchase the vehicle from them, leaving you unable to get your car repaired.

Dealer has denied to look into recall claiming that it is part of a warranty extension when it is a safety recall due to the issues I am experiencing. The car began to stall not even a year into me owning the vehicle. I had barely had the car for 4 months, not even enough time for my first oil change and my car stalled on me in a parking lot as I was driving.

Your engine failed to start and was found to be completely depleted of oil, which may be related to a known safety recall (SC336) involving defective piston rings. The dealership has had your car since March 14 but hasn't performed the required recall inspection or added oil, instead trying to charge you for diagnostic work you didn't request. Running the engine without oil could cause catastrophic damage and create a risk of engine failure, stalling, or fire while driving.
