I am reporting a safety defect issue that I believe is an alternator recall waiting to happen. While driving with my children, my Audi suffered a sudden, complete electrical failure caused by what I was later told is an alternator defect. The vehicle shut off without warning. At that moment, I lost braking power, the ability to shift into neutral, and full control of the vehicle’s speed. Because of this defect, I was unable to slow or stop the car safely putting myself, my passengers, and others on the road at serious risk. I request that NHTSA investigate whether this alternator issue constitutes a recall-worthy safety defect under the Federal Motor Vehicle Safety Standards.

The vehicle is a 2020 model with less than 55k miles and experienced coolant leaks. Specifically, the water pump was faulty and leaked causing coolant liquid to leak in additional lines and gaskets. The repairs resulted into costs upwards of $5k. When I first brought into dealer, the service rep mentioned that the fluctuating coolant lines wouldn’t be an issue but I further pressed them on doing a pressure test to which the issue was discovered. This is a huge safety problem if my engine was to overheat or face and other issues on the leak. I’ve never heard of a water pump going bad so quickly.

- The water pump failed, leading to a coolant leak and potential engine overheating. The failed component is not available for inspection, as it was replaced by an independent repair shop after the dealership quoted an excessive price and could not complete the repair in a timely manner. - A failing water pump can cause engine overheating, sudden power loss, or complete engine failure while driving, which increases the risk of an accident. Additionally, I noticed the smell of coolant inside the cabin, which could indicate a leak that might pose a fire hazard or expose occupants to coolant fumes. - Yes, the issue was diagnosed by an Audi dealership (Audi Northlake), which confirmed that the water pump had failed and needed replacement. Due to their high repair quote and scheduling delays, I had the repair completed at an independent service center, which also confirmed the failure and replaced the water pump. - The issue was confirmed by an Audi dealership but was not formally inspected by Audi corporate, law enforcement, or an insurance company. - Yes, I noticed a coolant smell inside the cabin for a few days before taking it to the dealership. However, there were no warning lights or messages on the dashboard before the failure was diagnosed.

Rear back up camera and 360 cameras do not work consistently and result in difficulty in backing up the car without complete visibility. This issue is subject to recall on 2021 and 2022 models but not on 2020. I wonder why this isn’t being addressed properly by Audi and NHTSA

Basically, when driving, the complete cars looses power and looses all electrical power. When I was making a turn, the car lost power, transmission and steering wheel locked up. Audi power system needs to be reviewed and seemed like the Audi dealership was aware of this incident happening to other customers. Quite dangerous

On or about September 19, 2023, I was driving to work when all of a sudden, while I was driving, I received 2 error codes: 1) electrical system maintenance malfunction; and 2) vehicle starting system malfunction. I proceeded driving to work, and when I got there, no problems arose. I contacted Audi dealership to inquire about the problems, as I had only bought the vehicle maybe 2 months prior. I was informed that the vehicle cannot be driven, and I need to have it towed to the dealership immediately, as the car would more than likely breakdown and I would be stranded. I started researching the issue and discovered that this is an ongoing issue that has been happening for quite some time. Apparently, Audi has been aware of this issue for YEARS, and has failed to inform consumers or customers because they do not have the parts in stock to do a formal recall. As of this moment, my car is still at the dealer, and I am awaiting confirmation that the issue is the issue with the alternator as it relates to the battery, which is faulty. I have been informed that Audi is aware of the issue and the part has been on back order for quite some time. it could be weeks, if not months, for them to have the part needed to fix the vehicle. I do not have a loaner yet, and getting one has been an extreme pain and inconvenience, but it appears that Audi will do nothing to recall this problem due to the part shortage. I am grateful I discovered the problem when I did, and it did not cause any harm to me or anyone I know. However, there are SO many cars still on the road that this will affect, and it is a safety concern that should be looked into further.

Recall has been open since the middle of last year. Defective part represents potential fire risk Dealer says they dont know when they will have the part to repair my car Manufacturers says no parts are available yet and they dont know when they will have them. This is not credible or reasonable. This vehicle is still in production and they are prioritizing sale of new vehicles over repair of existing safety issues

I purchased the vehicle as a CPO, two days (1/28/23)and 200 miles later I got a warning”Electrical system malfunction”. I turned the vehicle off/on and the message reappeared every time. I spoke to the dealership they advised that the issue is know to abruptly shut down power to the vehicle at any given time even while driving. I had the vehicle towed to the Audi dealership.
