“Hennessey Lincoln in Atlanta repaired my car in June 2026. My Torque converter needed to be replaced. My car was there over 20 days. Two weeks after getting it back from shop it started jerking and smoking. It needed another torque converter replacement. Two weeks after getting this car back it did the same thing again. I contacted Ford Warranty they did not help. Lincoln iin Michigan did not attempt to help. I couldn't even get the car in the shop for repair because of lack of employees that work on transmissions and no loaner cars.”

Problem could go unnoticed for an extended time.”

Evidence includes: Photographs of the wheel hub and broken/missing studs Mechanical inspection documentation 3. Inspection Findings A professional inspection revealed mechanical issues with the vehicle, including: Fuel filter failure Engine air filter failure Evidence of wheel stud damage Potential improper installation or pre-existing mechanical defect These issues indicate the vehicle was not properly inspected prior to sale, despite Carvana advertising a comprehensive inspection. 4.
