HELP: Miscellaneous charge?
Context: so we have a 2022 Audi Q5 with 65k miles. We had a power loss issue twice. The 1st time they replaced something for free and then one month later it happened agBTW. There is no sign or any codes that pop up. They had the car for 3 weeks and then come back saying they dont know what it is but they want to try replacing the engine wiring harness but are not sure if it will work. They are charging 4 grand but potential repairs can range from 6.5 to 8 depending on if it gets fixed or not. Is there any other options or should I just get rid of the car?? Because this is ridiculous for only having the car for 4 years. This is in GA btw.
