Consumer Description
I wish to report a critical safety issue with our Audi Q8, which experienced a complete electrical failure while traveling at 65 mph on the freeway on [XXX]. The warning indicators transitioned from yellow to red before the vehicle lost all functionality, including turn signals and emergency blinkers, posing a severe risk to my family and other motorists. We managed to coast to the roadside without incident, but the potential for a catastrophic outcome was alarmingly high. Audi has identified the problem as an alternator defect, which is apparently a known issue covered under an extended warranty for Audi Q8 2019-2022 for 7 years unlimited miles. However, the policy to address this defect only upon failure is unacceptable and dangerous. This malfunction could reoccur at any time, significantly endangering everyone on the road. Importantly, we frequently tow an Airstream trailer with our Q8. Had this failure occurred while towing, the consequences could have been disastrous on a large scale, endangering not only our family but also other road users due to the increased risk of a multi-vehicle collision, tipping over of Airstream or the Q8 if hit by vehicle who didn’t The replacement part's minimum of 3-8+ weeks wait time exacerbates our concern, leaving us without a vehicle or ability to use our Airstream which is one reason why we purchased the Audi Q8. I am aware of similar incidents of this failure in SF Bay Area across the past 4-6 months, underscores the need for immediate investigation and action to prevent future occurrences. We frequently travel on challenging routes like [XXX] in California as we own a home in Santa Cruz highlight the urgent need for a reliable vehicle. The thought of such a failure under those circumstances on a routine drive home or while towing, is unthinkable but could have happened to us at anytime. We urge the NHTSA to investigate this matter thoroughly to ensure the safety of all Q8 drivers public. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO
