What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2024 Audi A4, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
I purchased a 2024 Audi A4 with 20 miles as a birthday present for my son on 12/20/2023 for $45,028.81 cash, plus traded my son’s 2012 BMW 328i with 22,000 miles and they applied $8,500.00 credit. This is an Atlanta, Georgia Audi dealership. My son drove the car for one week and his salesman had an appointment set for him to bring his car back one week later to add Audi Connect Software to vehicle and my son’s phone. We took his car back to the dealership and they added the software and we left. My son told me several lights starting turning on in his dashboard but he could not take the car back that day because the dealership had closed as we were leaving the dealership. I called the salesman the next morning and he said to bring car back and they would check it. My son could not bring it back until 10 days later on [XXX], because he was sick in bed. His apartment is about 20 mins from the dealership so when he returned his car had 100 miles from only driving the vehicle to and from the dealership those four trips. Oscar in service dept said he needed to leave the car over weekend and they would check it Tuesday [XXX] since that was a holiday weekend, and Oscar gave [XXX] a loan car. Oscar texted my son on [XXX] saying his car had a defective air bag module and that module was causing all the trouble lights to appear on his dashboard, and they could not fix it until 30 days because they had to order part from Sweden. Oscar also said they had to keep the vehicle and it could not be driven until that part was fixed because of all the trouble lights in dash and he wanted to make sure the car would be ok when my son starts to drive it again. I don’t like the fact that the dealer has my son’s car we traded in and they have my full payment of the remaining balance after my trade in was applied to balance of car. Is this car a lemon and is it normal to buy a car only to have dealer keep it one week after Audi Connect software was downloaded? Thanks INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION
