2020 Audi Q8 Complaints

    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 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...
