Business ProfileforMcKinney Buick - GMC

Truck brought in by tow for an issue - They did not check In and left Key Asked for service and Diagnose possible issue (Diagnosed and charged $2600)- Paid cash Was falsely accused of neglect and told zero oil after they started. They j voiced me and said my warranty which is through GMC under Manufacturer and also have extended would be voided. I complained and *** accepted responsibility. Agreed that workmanship error and warranty approved, February -May I spent thousands on rental which documented would be reimbursed by GMC as long as I didnt call GMC- Loaner was given as they had diagnosed and for a few days would be ready. A month later they had billed me 3 dollars a mile over mileage despite putting timing chain on wrong, and dilute to communicate. Threatened to call police on me on Friday that personal emergency prevented travel (They wanted to sell car as a demo and maximize profit while charging 3 dollars a mile). Under duress and fear had towed despite medical emergency. Despite my documentation and request for records *** GMC GM and ******************* (Who said she was the contact and tech) documented in writing issues and ******* documented invoices to their needs which I have in writing. I picked up car and less than 48 hours the services rendered were not done and my car overheated on highway. Ioened hood and no coolant or fluids and screws and bolts holding the fluids not connected and tire was leaking which they documented fixing . I was told I had to bring back to them but in fear and months of threats, workmanship errors, ***** accusations, and verbal abuse I had taken to another dealership to diagnose. The AD documented that because workmanship error the car had extensive engine damage from GMC Mcknney failures. Safety for family over fear/bullying.Safety concerns I had to pay . *** and dismissed every concern in writing, After many attempts *********************** yelling at me offered $500 for NDA signature not to ever speak or contact or see in court
