The torque converter is defective in my 2018 Acura RDX. I have received flashing warning lights on my dashboard in Red " Check Transmission." This warning light is due to Acura's defective torque converter. The torque converter affects the shifting of power during driving and cause hesitance or shuddering when attempting to accelerate.which causes my vehicle to sometimes to have a decrease in power . This affects my safety while driving my 2018 Acura RDX. Acura is aware of this defect and safety risk. Acura Client Relations informed me that Acura was mandated by the government to provide a Warranty Extension for the 2017-2018 Torque Converter. I received one of these notices and took my car for the repair. I left my car with the dealership for 6 days. The dealership decided that they will not repair my car because they have determined my car has a "branded title." I purchased my vehicle used from an Auto Body Shop. My vehicle was declared to be salvaged. My engine/transmission/torque converter is the original on my Acura RDX. and was never damaged or repaired. My RDX torque defect should be a safety recall because it affects my safety.

I am unable to find a dealership that will perform the repair, please help. They all say they are short or parts and are only fixing vehicles experiencing issues. I lose power when accelerating all the time but this apparently is not enough.
