NHTSA Complaint #11718670 — 2025 AUDI Q6 E-TRON

While driving on the freeway in the carpool lane, our Audi Q6 malfunctioned and lost power. There were numerous malfunction lights all at once. No other warning that the car was about to lose power. I was forced to coast across lanes avoiding traffic to the side of the road. Steering wheel was also violently shaking. The car has been out of service at the dealer for 58 days as of today. The manufacturer and dealer have both spent time analyzing the car and replaced the 12 volt battery and some control modules. Here is the text message I received from the service advisor at the dealer: “the following are the latest notes from the technician and techline audi :The control module for engine and suspension control is the module that has the static low voltage faults. Tech line thinks this control module staying awake is what’s killing the 12 volt battery. A faulty or discharged 12 volt can cause several problems in an electric vehicle” My concern is that there is no advance warning that the control module or suspension control is draining the battery and there is no advance warning that the 12 volt battery is going to die or is discharged. Audi has not been able to provide reassurance or confirmation that we will know in advance of this issue happening again. We were fortunate to be able to get out of traffic and to the shoulder, but it was a dangerous situation for me and my family to be in. With no advance warning, it seems a good possibility this can happen again.
