My wife was involved in an accident with her Audi Q4 E-Tron on Monday, August 7, 2023 at approximately noon. She was driving into Boulder to pick up our granddaughter from an art camp in Table Mesa. On her way to Boulder, she noticed that the lane departure warning indicator light was not working which was odd because she had been using that since she purchased the car. She was also in Drive B (regenerative braking) mode. She drove into the parking area and was pulling into a parking spot very slowly. When she moved her foot off of the accelerator towards the brake, the car lunged forward at an incredible speed. She pushed on the brake pedal with all her might, but it did not stop her from crashing into a pole, another car and the store front of Weaver’s Dive Shop. This resulted in damages that were determined to be a total loss by the insurance company. We have researched the web to determine if this situation has happened to others. We were not surprised to discover that Unintended Sudden Acceleration is a known issue. However, this occurs very rarely and happens when the car’s computer gets confused by the signals from the battery, accelerator and inverter. Dr. Ronald Best has been researching Unintended Sudden Acceleration for over 10 years and has published a number of articles which document his findings and how Unintended Sudden Acceleration can occur due to what he refers to as a design flaw. We have saved & printed out documents which address this issue. I am attaching the most relevant article by Dr. Ronald Best. State Farm, our insurance company compensated us for the total loss of our vehicle. We were not made whole because the car was 10 months old. The State Farm report is attached. We submitted a request to Audi National Customer Service to research the car to determine if there were any issues and to have them compensate us if there were issues. Attached is their response followed by our response followed by their final response.

I was hit by a large truck on the driver side as I was in the right lane catching up to a safe speed. The hit spun the car around at least 180 degrees. Due to the massive pain I couldn’t move. The car just shut off completely to include all functions. There were no prompts from the car’s emergency to call for help which I find as a fault. Luckily I was in a populated area and emergency was able to respond. I am seeing reports in forums with photo evidence that the SOS function is malfunctioning. The car is likely in a junk yard. I took the car in a month or so back for a charging module fault. Audi in Lehi claimed to have seen a significant number of faults but couldn’t identify and remedy them.
